- Our in house Expert Charlie and Vince took a look at the differences between PVA and our own SBR.
Tell us what you think? Do you use PVA or SBR?

Used to like using your No more ply SBR. For some reason is not giving good results of recent
Do you a tiling video which shows a)how to prepare/prime the wall prior to tiling and b)how to tile after priming the wall? Also how do you make the wall waterproof prior to tiling?
Can you paint over SBR?
Ok i get what you are saying but what about if you use exterior PVA
Can i re prime with sbr when it has already been primed with pva
Thanks for your great video very helpful.
Is there a good SBR I could use to prime an external wall that has masonry paint.
The paint is sound and not flaky.
😊
Thanks for the question. Although we are not specialists in priming painted surfaces, I could recommend using a Sika acrylic product, and would also recommend checking with Sika for the best product from their range.
@@stslimited9160 ok thanks for your reply 👍
1- Waterproof surface VS PVA
Yes, after 3-4 coats and 48h + of wait time, and most likely it will be a very slim film that is waterproof, similar to a sealer I reckon.
2- Eliminates dust VS PVA
Well PVA sort of eliminates dust, but I assume key point is that the dust will not stick to the SBR applied area ? I don't think this will make anyone rush to buy SBR.
3- Best adhision VS PVA
We need to see stats on this, tests made. How significant is this "best adhision", when adhesives stick to a non primed PVA wall anyway ?
My actual question is, why would you test this on a gloss tile which doesn't absorb the PVA or SBR and not test in a real life scenario, on plasterboard or whatever ?
I could brush some cheap sealer on that tile and get the same results that were shown in this video :)
Cheers
To be honest there should have been a number 4 (or at least mentioked in point 3) and that's the major one. SBR when set it no longer water soluble, PVA when set is reactivated by water. So when you smear some adhesive over SBR it gives you a nice pull on the trowel and sticks good. PVA is reactivated and turns to mush giving shit adhesion
Show how to remove tile after time not like that lol...... I use PVA and iven remove tile after long time the tile is bont like hell...
Hi, thanks.so I shouldn’t use pva on a plaster wall before painting..? What do I use ? Thanks
Hi, thanks. The normal way to prime a newly plastered surface is with watered down paint. The standard recommendation is a 70:30 mix of paint:water. Apply this mist coat to the plaster and allow to dry before applying your finished paint surface. Hope this helps :)
What about before plastering an old internal bedroom wall?
ive been plastering 40 years i use a neat sbr as precoat then sbr 1 part pva 1 part and 3 parts water as a second coat plaster when tacky
Very helpful video, thanks. What ratio SBR/water would you recommend?
Hi Mark, Thanks for asking. We recommend 1 part SBR to 3 parts water. Just so you know our 6mm NoMorePly boards are Pre-Primed however. :)
Is mapei( primer g ) similar to sbr ?
Yes it's a similar product, they are both an acrylic and latex based primer.
Great video guys.
So you can use instead OF Arc primer..do same think
Yes that s correct.
What is Full form of SBR
Styrene-Butadiene Rubber (SBR) is a general-purpose synthetic rubber, produced from a copolymer of styrene and butadiene. I trust that helps.
Thanks was about to comment asking what is SBR - I haven't heard the term here in Australia before
Those steeple fingers are all wrong body language for a video like this... aside from that. Good stuff
SBR is far superior than PVA
I never allow PVA on any on my build sites ...
helllo bro what is ur nimber
