- On this one I show how I float finish my sand and cement render smooth with a sponged finish giving tips and my technique on the way I render from start to finish ,plastering is no easy task or job exterior rendering has many variables with weather background materials and so on , The mix I am floating is 4 sand to one cement with water-proffers and plasticise in the render mix using a hawk and trowel to get it on and a straightedge to rule it off and get it straight and ready to rub smooth float of with a float and sponge finish Links bellow to the other stages and videos that are similar and related

Thank you brother means the world :) Have a new video out in a few hours if you fancy it :) Than you again for watching and supporting :)
You all probably dont give a damn but does someone know a trick to get back into an Instagram account..?
I stupidly lost the account password. I would appreciate any tips you can offer me!
@Ira Esteban instablaster =)
@Gannon Kamdyn thanks so much for your reply. I got to the site thru google and Im in the hacking process atm.
Takes a while so I will reply here later with my results.
@Gannon Kamdyn it worked and I finally got access to my account again. Im so happy:D
Thank you so much, you saved my account!
I'm so glad you showed your presentation from start to finish,
glad you liked it my friend : ) We have a few more videos similar if you wished to see them :) thanks again for watching and commenting :)
Excellent teaching. At least now I can do my own brick layering, plastering as well.
So glad its helpped you
another great video. Looks like a great job mate well finished. I try my best but I can never get it that good ,but watching your videos always gives me good tips and things to try out next
👍👍,
Im using some sbr in the mix it can make it harder to finish as its stickeyer very sticky compared to just mortar mix and water proffers , Dude I am glad that you can take some things from the videos even if it just some ideas that can be tweaked to suit yourself means our videos are helping :):) As always more to come :):)
Well explained mate and the end job is superb full marks 👍👍👍👍👍
Cheers Mark mate hows things are you back from the resting yet ? :):)
On ya lad keep them coming brother! 😎 Good demo ✓ Good info ✓ Nice work! 💯
hey bro thanks for the feedback mate :):) Always more to come :):)
You're a very hard worker
Thanks Norma hope your having a good weekend
I love the rough look without the floating stage. The wavy Spanish-type look (not level and with rough texture/feel.. My sister has it on her house in the countryside down here and I saw it also in Spain and on posh holiday cottages in Buratty Castle area (left of the castle about 300M) when visiting during the summer. Perfection in imperfection or what the Japanese might call Wabi Sabi. In Ireland we just render exteriors smooth most of the time I feel because we think that's the way it's "supposed to be". The imperfect Spanish type look I feel ages better over time, even when dirty looks less "off" or "wrong" My thoughts.
Yes some of the house i seen in Spain i liked but some was just to rough for me LOL do like a smooth wall but texture sure dose have its place also it seems also big in the US also I thinks its due to the hot weather it must make it easier to finish and possibly crack less with heat
Nice job, cool few vids Mac 👍
Hi Michael mate thanks buddy hopeing to be getting some skimming ones out soon , thanks again for watchong and taking time to comment mate
great finnish! just to say sometimes I nail a bit of carpet on to an old float and use that ,all the same great video mate !carry on the good work
Never seen that technique before what kind of carpet , dose it rip in to the surface much ? Thanks for watching and supporting buddy :)
as long as the offcut has a soft pile you can rub up but you must use a light touch ,just like a sponge
@@markstarkey6423 nice one for sure want to try this its a great idea man:) :)
Nice job mate 🖒
Hey Jordy buddy thanks mate hope you having a good wekeend :)
Just a perfect looking finish at the end there Mac. Love how smooth you managed to get it and how sharp it looks.
Hope you and the family had a good weekend. You mentioned it has been warm there and I hope you're getting a chance to relax outside while the getting's good and that it's not so so warm out that'd you're melting/can't enjoy it! Have a good week :D
Hey Annie had a great day yesterday was very warn and got out and about :) was a fun day very good weather :) Back at it , Hope your doing good Annie and getting out at the sun a little :)

Very informative video - thanks for sharing 👍
Hi Paul Thanks for the support and feed back buddy means a TONE :):):) should have more on Sunday /EVERY Sunday lol :)
Great videos mate. Thanks for posting!
Thanks for watching and commenting buddy more Videos every Sunday :)
nice job u covered everything a fella needs to know step by step how to get a good finish on the render.it sure is down to timing it right aswell.i before made the mistake of floating it in wet and having to wait for ages to finish it.keep it open let the air at it works best.👍
Hi mate for sure keeping it open at the bottoms is a must, and i must admit sometimes its hard to wait haha and want to get it smashed out and away sometimes you know yourself the bottoms just about rub in wet but other times can be a nightmare
@@macplastering ya sometimes we just cant help ourself by trying to finish it asap but i sure can backfire as u said mainly the bottoms and when working into a stop bead or rules its harder again.i always try fill them out as much as possible in the scratch coat so its that bit less of dept on the finish coat
@@emmettmccarthy7247 Yes i do very similar s it wont sag at them parts
How do I begin what materials do I need I'd like a shopping list of what's needed to do this plz
Beautiful. That's what I'm talking about
Hi Asghar Mate glad you liked it :):) this is a very popular finish here :)
Years ago we was working with an old plasterer.
He said those plastic floats are crap the wooden ones used to last forever.
My mates said why haven't you got one now then
Haha thats true I would like to try make a wooden one up to try out for fun LOL but these can last a decent time if looked after and nice and light easy broke in so float well I found that if you let them kinda get dirty almost let the cement burn into them some they last a little longer sounds crazy as every other tool im like clean clean clean but I have let my flats get a nice stain of cement on them more so the back and it seems to make them more hard wearing might just be me though Thanks for watching buddy :)
Another helpful and good vid thanks mate
Thanks Simon man what job are you guys on these days ?
Plastering, rendering and any other jobs that need doing buddy
@@simoncrewe5625 Thats it mate take it all on :) do you prefer skimming or rendering ?
Atm if I'm being honest I prefer skimming but am liking rendering more n more. I'm still learning, not qualified. Been labouring for plasterers for ages. Sick of earning chump change so the last year or so bought the tools n learning. I can only get better buddy 🤛🤜. And watching your vids n others can pick up huge beneficial tips. Thanks again mate
@@simoncrewe5625 You and me both know its hard work doing either plastering or labouring respect to you man getting the tools and getting on them ... We also both know it can be hard to learn and get the knowledge needed to relay succeed this is what I hope my channel can hep the new to the trade excel faster and get them little things that took me years to learn but if I knew at the start could a helped me more , but yes man stick at iit you will only get better and better until you look back and see how far you've came
Quality finish m8👍👍👍
Thank you buddy means a tone from my follow Plasterers :):)
Thanks for the video
Hi dude thanks for watching :)
Nice job
Thank you David mate hope your doing well buddy
Good stuff nac 👍👌
Hi mate thanks for watching buddy this heat is so good hope you getting time to relax in it :):)
Nice job mac only criticism is rendering to floor level. I use Bell cast bead just above damp course to avoid bridging it.
Normally would do a step in or bell for dash or a nice big base / plynth but on this one i match the front and side so have to stick with whats there not sure you see the painted side at the corner LOL
Great video
Thanks buddy :) hope your having a great week :)
Thanks same to you.. im just starting out. What trowel would you recomend for sand and cememt and skimming.
@@johnny545 Morning buddy Loads of great trowel out now , I do love my Refina premium , but dont use it for floating anymore I keep it just for skimming , I would normally have 2 trowels one for skimming and one for floating witch i will be breaking in for skimming , but lots of trowels out at the min refina tyzack ragni and marshalltown also they all have rendering trowels now and superlfex trowels for finishing I think this is the one I tend to use the most for skimming = amzn.to/2O8Lrug that links is an affiliate but as you can see they are priced well , if you get time look over the channel you will see how long I have had it , it was unboxed a long time ago , one the reasons I do unboxings to help me date how long the tools last :) Sorry for the massive reply :)
also forgot to say Ox
Ur too good mac you'll have them doing it all themselves they'll not need us lol
Haha monty mate thanks for the nice words , will always be work for the hard workers and the guys who take time to be clean and tidy and do there best, and besides this game is hard Im told only a plasterer is tough enough to do it and mad enough to love it ;):)
Looks great, the pressure is on you to get it finished , A hot day doesn't help. Do you have a helper ? great video
on bigger jobs I team up with other plasterers but this is just 1 wall :)
yes hot sunny days put the pressure on big time
Have a good day
Thak you Norma
Hi, what sand do you prefer for render? Apologies if you covered it and I missed it. Appreciate all of you videos, very helpful👌
Hi buddy hope your well, I would have probs talked more on it on the mixing videos we have but to answer you I like plastering sand always the sand we have here is pretty nice to use
Thanks, I’ll go check out you mixing vids then. Cheers 🍻
I’m on sand n cement at mo still managing to rub up next morning taking hours to dry 🤪🤩
Oh mate we job we where on builders got us ready mix it took ages to rub actually have some great footage of it to come out soon :) how i go it to dry a little better :)
@@macplastering oh ok I should have tried a heat gun fir paint stripping might have speeeded it up,same again today all on by 10 and rubbing by 3ush ave go back in the morning to finish 👎, shame u can’t use a scratcher on the top coat to finish
@@HSilver341 Mate I think you'll like what way this video is
That's gorgerous job! May I ask what float you are using? wood or magnesium?
I need to make myself a nice wood one this one is a polyurethane float they are super nice to work with light and break in fast, Thanks for the comment Kenny brother :)
About to render a garden wall i built, im a Bricklayer by trade, never rendered before,
Oh nice one mate we have a few on rendering but as you will see the are mostly the same ratios on just block , some ones on how to get it straight before its finished
Quality plasterer
Thank you brother means a tonne :) Hope your well
Nice job!
How do you know when is the right time to start floating?
Hi mate all about timings but i check it with the float yo see how it feels and my finger push it in see if its tighten any thanks for watching and the comment buddy
Hi Mac, just a quick question, as the weather is cold now ,when do you not render outside .. i have a small job to do outside ? I know it's warm when you released this video.
You want 5 and rising buddy temperature you certainly dont want it freezing as it could blow off / crack or just not set / cure for you to finish it well you can use frost proffer to speed setting time up :) Hope this helps mate will try and get a video out on it in the coming weeks
@@macplastering thanks for reply, 👍👍
@@anthonykenny1120 Any time Bro :)
What kind of float do you use?
Its a polly here then sometimes a powerfloat also sometimes use my refina diamond float i think its called
Did you render over the DPC? I thought it had to stop 6” off the floor.
Dont think there was a dpc in this mate and garage might be lower than outside at back if memory is right and i have seen loads of new builds stright to ground but in my own house i will be doing a plinth again think about them over the dcp but thicker and sloped at top keep an eye for newer videos you might like them making bellcast and setting beads at dpc will be right up your street mart mate
What would be the best sant to use? plastering sand I'm using at the moment is very gritty and seems to tear when floating even when still wet!
Washed plastering sand is best it real nice to work with got sand in for the wall I built its very red and is pretty sharp more like paving sand than plastering sand luck i aint got to the top coat yet but will go for a better plastering sand myself such as bagged washed plastering sand Hope this is helpfully buddy
I usually just wet the wall down and then float it up it's a lot easier he was going over it and over it which is kind
I rather rub it when its ready dont like wetting as it stains it no difference if painted but looks better
@@macplastering hi bud hope your well after your scrach coat as set and your doing your top final coat how do you get it nice and level bud
Have you a video or link I can wotch please Tc
Hi Mac, do you float straight after levelling? Cheers
I would if it was drying mate it all depends how well the gear is drying it will determine when i go at mate
Nice job pal, any tricks to break in a brand new float. Apart from a lot of floating. This day and age with the new trowels being broken ect, you think they’d do the same for floats.
Thats a real good one man I would say if any the tool companies read your comment they will be trying to find a nicer edge on a new float ready to finish render :) but yes to answer you mate you can use sand paper or if you have find sand paper you could use a block to rub corners down some then tidy it up with sand paper , I love my float I used here but you want to see it now it well worn in almost for the bin tbh and I will be in same boat as yourself trying to get one broke in nice loads of floating :):)
mac plastering I’ve a few garden walls to do and my old well broken in float, was robbed from a job a while ago. I have a newish one, used it couple of times before it just not that same. I have rubbed in the corners a bit with sandpaper like you said. Thought you might have know some Indian trick I might not have heard off. Anyhow such is life. I’ll carry on regardless. 😀
@@phils3631 Haha not thing better than just filing it down or the long hard way grinding it on sand and cement lol , if you know any guys do floor screeding lend it to them be ready in a week lol I know the feeling mate a new float is so bad for finished render it digs in way to much also i find you almost need to let the gear go off than much more than with an old broken in float you can get onto it sooner and across the wall faster , im still tearing away with the power flat trying to get better with it and i am getting better with every wall getting the hang of it and find you can near let the wall set solid and it gets it in all the same
mac plastering. While I have your attention, where did you pick up scup, hard to come by down south here in Wicklow/Dublin areas. I’ve been using a scudder for scoping out of tubs. A lot of bending up and down. Anything that makes life easier, you know yourself.
@@phils3631 The big refina one think its called the refina mac scoop lol but i dont get no commissions :( :( LOL If you look on the refina web site should be there mate if you cant find let me know
How come you scratch coat it and not do a slush (flick) coat? Slush coat is quicker. I dont use sand and cement mix any more. Premix render bags are the go here in AUS.
Didn't need to scud coat no suction in wall and plentey of grip on the blocks but have scud coat videos on the channel showing why im doing it there also have sbr in this mix again more videis on sbr aswell mate
Is there anything you could put in the mix to give more time in hot weather
Water proffer int he previous mix to slow down more on suction and plasticiser in the render mix will slow down the setting time and give good workable but to much is bad and can lead to cracking and failing render
I've just had my back of my house done and it's nice and flat but its covered in swirly lines of scratch marks as if there was larger pieces of grainy sand dragged through with the trowel. Is this normal?
Can be hard to know with out seeing it Render dose have a slight texture i think i have another video on finishung render with up close shoots in it but it might just be how tge other guy leaves his work
Waterproofer in scratch only or in top too? Also I noticed you use SBR in the top coat, how come? I notice you're not a big fan of lime too? Or you've never uesd it in your vids anyway. Cheers Mac 😎
Hi bud hows things , some guys like it in both some lie it in top coat only others in scratch coat , all about what works for the applicator I guess , Lime burns 10 times worse than cement if I was to use it , it would only be a little per mix some guys like 1 to 1 to 3,... 1 to 1 to 4
@@macplastering good thanks Mac, hope you're well! Was just interested in your methods, so you essentially waterproof both (with sbr?) then? Does it make it sticky to rub up in the top coat or is it ok? Also how much do you use per mix/ gauging bucket? Nice one
@@ljones396 dont always use sbr in top coat as it can be harder to finish it is sticky to rub and sets faster too , think i show the ratios on this vid mate - th-cam.com/video/Tsw-t8mwLRI/w-d-xo.html
@@macplastering ah, sorry, I got confused between the vids, of course, it was in the scratch. Long day, dont mind me 🤦🏻♂️😂
@@ljones396 Oh mate dont get me wrong I have done it in top coat on walls that are going to be always hit by water trying to do it over kill strength and waterproof but it can be a pain to finish .
Can this be done with a wooden float????
For sure mate i have been looking at some myself might give them a go
you made hard work of that !!! not enough render in the 1st place
thanks for your input all thought its useless and not true its your all the same have a good day clive
Hi mate, I've had my house rendered with sand and cement, the guys done an awful job, looks like a Spanish Villa, problem is it isn't smooth as stated it would be, it's noticable in the daylight, do I have any options to making it better other than hacking it all off and getting it redone? Is grinding/filling it an option? Even though it'd be time consuming, is it possible?
Cheers
Morning Graham buddy , sorry to hear about this job , I wouldn't think it would possible to grind / sand it down them touch up and make it look like it wasn't patched
Are you going to pant?
is it only bad at certain time of day when sun is going across it?
Thanks for the reply, I am going to paint it, I initially was going using Dulux weathershield but now I'm wondering if there is a textured option that would help mask it also, Mrs is quite particular on the colour though hence going with the weather shield, she chose a colour from there, large patches would maybe look better than the shotgun look it has currently haha and yeah depends on the sun's direction and strength so during the winter it wasn't so noticable but as we are getting a bit of sun now it's driving me nuts
@@spazpecker Only reason i ask on the sun was sometimes even then best work will look bad for an hour or so when it is being hit across by the sun, you could try sand scrap back all the high areas but getting it neat again will be very hard as it will open up the render and youll have to chose on how to re fill them areas and getting something to bond well would also be a problem.
so your main issues would be
scrap down get it level
then refilling and making it stay on
then how to refill and make it look good
These would be hard but if you where to say give it a go on an area not seen as much like a test area , I would do this actually use a small half block or brick something that is abrasive or a grinder with attachment if your good with it and its safe , So start on any waves lines marks lumps that are proud and rub them back its going to be sore on the arms.
so say you go the whole wall done any real heavy holes that say apparel you could try fill with a wet mix of 4 to 1 or 5 to 1 with sbr in the mix also painting it on the dusty surface to seal it after you dust or wash it down. I would trowel it smooth then using a sponge or sponge float providing these is not much depth to the render being applies rub it smooth paying real attention to the edges to avoid it looking like a mess getting them flush feathering to nothing this will be your real challenge.
So you have the whole wall filled but it now looks a little patchy probably diffrent colours but hopefully after the hours hard work put in it is a much better shape , it at this point might look o painted all one colour but if you think it would need a little more you could make a 5 to 1 slurry coat with sbr mixed in loads of sbr and basically sponge wash the whole wall witch again might help blend in the bad areas fill small holes and will dry out the same colour.
I wouldn't relay recommend this as it would be a lot of work and work that might not pay of for you mate but if you did test an area to see if it was going to help heal it or make it worse do it in as blind a place possible ,making render stick to smooth render is very hard why i say use sbr as its a bonding agent and very strong , but make sure to wash every thing down as you go and cover up everything you dont want ruined it wont set for like 12 hours but dont let it set to anything you dont want it to set to such as tools sponges buckets , around your windows glass room gutters drain pipes dont let it in any drains it will block them , I know you know this but its good to have a reminder
The other option is to chip all of go again or like you said use a highbuild product that has a texture to hide it highbuild is trowelled on then hit with a roller to texture the walls sometimes things like this can relay hide cracks and ugly but sometimes ts also just putting ugly on ugly so again test in a small area out of sight and see if you like result when wet it could still be scrapped back of.
sorry for this massive amount of words I gave you to not just read but climb over hope in them you found something useful and helpful
Mapeii do a thin coat acrylic render that is easy to apply and scratch flat . I believe from memory that it has minimal depth of 3_5 mm and max of 10-15mm. I have used it and found the results are good.and I am a DIYer ....
Is it ok to add lime for the top coat, 5-1-1
I wouldn't use as much lime I know some guys do but things work diffrent for diffrent plasterers , this one is simply 4 to 1
Have you ever rendered over hardie cement board? Put it on my house and I don't like it. I am thinking of doing rendering over it.
Think i have skimmed and binded and skimmed over it but never rendered over it, from what i rememer it dried super fast in me no matter hiw much prep i did
@@macplastering Thank you. I appreciate your professional opinion 👍
@@ricos6243 Anytime mate always here for help or tips and ideas :)
Should’ve used your Derby or a rod then you wouldn’t have to fill in all those empty spots just wait for it to set up floating was a hard rubber float
For sure would made it easier and slowed it down from setting I cover that a lot in the channel on this wall i did want it to set faster so i could get it rubber so left it open thanks for the commenting and watching Ryan mate

Do you guys up there cement render over Fibre-Cement sheet? If so have you done a video on it? Down here in Oz it's called BlueBoard and is used extensively. A render finish is popular as it gives the appearance of rendered masonry but a fraction of the weight/cost. Acrylic renders are available but quite expensive.
I'm currently using this product www.dunlopdiy.com/pdfs/renders_datasheet/Dunlop_Fine_Coat_Render_Datasheet_2.2018.pdf over primed FC/BlueBoard cladding. The product is designed to be "flexible" to accomodate BlueBoard. Having all sorts of issues floating it off. Very patchy with some areas going off, then right next to those areas pulling material off the wall when trying to float it. It can't be refreshed with misting. PIA. only need a thin cover but considering increasing the thickness to give longer working time. Would be very keen to see some info on rendering over FC sheets.
Keep up the awesome videos. Been very helpful.
1st time I ever worked over it I was like ok whats this , it was in a fire place guy wanted it to be fireproof so used it on the whole inside, so i looked at it and thought will need pvaing as it was the smooth side out also needed bonding as screws where not in and if you put them in more would just bust the sheet, so i got the pva went to get water ready for mixing came back and pva was bone dry so i pva it again get mix done and again pva was dry at this pint i know this is a nightmare so put pure pva witch still pulled in super fast and was able to get my bonding on it and beads stuck but no jokes it still set in 20 mins ready for the skim so yes I pva the bonding also and my skim was fully finished in around 40 mins , seems like real hard gear to work with did a bathroom with same stuff also was a nightmare had to do 1 wall at a time as it was drying so fast, sbr might be a good call to prime it but I haven't do that , If i ever come across it again will recorded my battles with it , Thanks for the support buddy its much appreciated. :)
@@macplastering Wow, ok, good to know I'm not the only one who sees this as a PIA. Next time I see somebody rendering it I'll find out what the secret is ;) Primed with an acrylic primer used for tiling adhesives etc. Should suit this. Got another wall done, but super slow and not convinced the bond is great. Would be awesome if you did a video when you next come across it. Not finding much on line about it.
