In this video I'll show you how to parge your insulated concrete foundation (ICF). Follow this two step process for a beautiful looking wall that will be durable and look like concrete.
I wasn't aware of what parging was so thanks. I have to figure out what to put on the outside of the ICF extension that is planning to be built Spring 2023 on Prince Edward Island, Atlantic Canada. I am enjoying your video's and have watched a few several times so I understand as much as what you are teaching about ICF extensions, to a poured concrete basement and then stick build. Cheers and thank you so much!
Just poured my walls today. Your videos are the only ones that actually explain how the icf works in real life experience. Anyway, thanks for the info from Indian Lake NY
Gre After watching your video we went to work! Our first coat and mesh went on well. After 24 hours of dry time we started to apply the second coat, it dryed immediately upon applying it and was not workable . We waited another 24 hours, same . Any recommendations would be much appreciated .
Could a whole ICF exterior be parged and last? I’m just wondering if that might be the least expensive siding option and not have to have expansion joints- and be forest fire resistant.
Regardless if the mesh is sticky or not, the best way to apply it is the way that you did it. You get a much better bond by sinking the mesh into the mud.
Samuel. I have to agree with you on that one. My buddy tried to do it in one coat. Customer was not happy the mesh showed through. Put a second coat on and light broom. Looked awesome 😎
So you Would you still do the scratch coat if plastering icf but then attach wire with fasteners to ICF. But no synthetic mesh needed really? I have an addition with ICF I need to match to main house which is also not finished. It’s 1/2 treated plywood on the base of original house because I had done new foundation walls all around a year ago. Nothing finished yet needs stucco.
I would attach diamond wire lath with screws and stainless washers to the ICF studs then do a scratch coat. Notch the scratch coat with a notched tile trowel. Let that dry a day and plaster it.
What is the products name that you used? I just had a frost wall installed under my camp, and didn't know if you cover it or not. Now I know, I got more work to do.
Thank you for the great video. I had a quick question (if thats ok). I have an ICF wall foundation to parge and the way the house is built, the bottom of the foam board insulation overhangs the foundation and siding is attached to that. Should the bottom of the foam board be sealed with parging as well?
Here in Alaska the Nadura distributors don't have this product. 😐 What could be another option for something that fine? We used the rubber membrane for below grade stuff. But this is for the shop above the slab. So about 6 inches.
Enjoyed your informative video on parging. I applied 1/2" treated plywood to my exterior ICF. I want to parge on the wood. Should I do a scratch coat and press the mesh into it or staple the mesh to the plywood ? I have the nudura product and fibreglass mesh.
@@timdurant6920 I'm just reading your comment here ,, I did almost the same thing as you did except I used cement board. I was wondering if the parging stuck good to your plywood , because when I did my cement board it only lasted about 6 months and then started cracking and parts actually separating , the reason I went with putting the cement board on the ICF was probably the same reason you put plywood ,, for better protection from being hit with eg. kids bicycles ,, lawn tractor , you know what I mean lol.
@@mrmikestandard Hi Mr. Mike: The 1/2 inch treated plywood was partially applied by the framing builder mostly in hard to access walls or walls that were backfilled - I finished the plywood for that reason and parged for a finished look and prevent the plywood from drying out on the south side from sun exposure. No cracking for me except at one corner where I had issues with the plywood getting fastened tight. It has worked out great mind you I didn't skimpy on coats nudura and made sure I had enough for pressing the fiberglass mesh into it. No problem with damaging with toys😉 as our residence is located in cottage country and grass is not important - lots of rocks 😂
Ron I would think so but again I would rather have you contact Nudura with advise on doing a pool. Id like to see some videos of pools from ICF blocks. There is a few on TH-cam. 😊
@@bondobuilt386 Yeah I've been investigating this and have watched every video I can find. Nudura has a product with foam on one side and wood that can be unscrewed on the other side. I wanted to try to pour the floor and walls in one connected pour. Pour the floor first then the walls. I was going to cut 4" off the bottom of the inside form to run steal from slab into the wall, and allow everything to connect seamlessly. Like your monolithic pours but also add the slab in 5he same pour. This would be kind of like a DIY gunite pool but poured instead. Your thoughts would appreciated.
Ron Chamberlain I think it would be a good idea to not have the foam on the inside like your thinking. I poured a floor and wall like that. I’ll send u the video buddy.
Thanks for the video. I have watched a lot of ICF foundation videos and it never occurred to me to ask my contractor what happens to the above grade portion of the foundation. I double checked the contract (not signed yet) and all I see is this: "7) foundation coating on walls below grade" It leads me to ask what happens above grade. I am awaiting a reply from him now.
@@bondobuilt386 I just got off the phone with the contractor. We are up by Oneonta NY and he stated he doesn't like parge as it will likely crack due to weather extremes. He mentioned vinyl stone veneer siding, regular vinyl or stone as options, stone being most expensive and stone veneer in the middle.
@@wagnerj01 It wont crack if done proper. We live in upstate New York. The mesh must be installed that keeps it from cracking. We have screwed stainless steel diamond lath to the studs and parged it with Comproco Which is a parge coat with fiberglass in it that is used for concrete block basements. That has more impact resistance. We have also covered it up with products like you mention. 👍😊
Good video man! I’m looking to do this soon I plan on attaching stone to the ICF blocks maybe I should use a metal lath type screen instead? What are your thoughts on this?
@@jesselytle7367I just have the bare ICFs is building paper AKA (Tyvek) required for shedding of water should it get behind the final surface? I’m going to make my own Stacked Stone There’s nothing on youtube showing this process
Uncle Jim. 😊 I can thank my dad for pushing me when I was younger to learn new ways of doing things.A lot of things I just learned myself by researching or. by trial and error. I have always loved building things ever since I was old enough to cut down a tree with a hatchet. There is just something so satisfying when you create unique structures. 👍😊

George I love hearting stories like that. So glad my videos are helping you Folks out there. 😃
Nice video, just what I needed. I love your channel!
You made that parting look so easy, now I want to do it.
Awesome bud. You can do it it’s not that hard. Let me know how you do. 👍👍
Way to go Bondo! The texture of the broom finish will bite mortar, too.
Thanks for the video, a job similar to this just dropped onto my plate.
Can you do this over foil faced rigid insulation?
I never have but I would think so.
Appreciate your videos, man. Keep up the good work.
What do you use for finish coat?? do you prime it before finish coat? what brand is it??
Exactly what I needed. Thanks.
Can you use this method if the wall has Styrofoam SM on it instead of the Nudura blocks?
Do you need to rasp the block beforehand? Can you parge over the waterproofing?
Great Video, Thanks.
Just about to do it. Thanks!
Hope the video helps.
can you put the second coat on a day later or longer
yes you could the next day or longer.

How long between coats can you wait. Would a couple of days be ok?
Are able to but on a stone face after scratch coating?
I would do 2 coats and the second use a tile notch trowel to rough up the surface.
Was wondering the same. Might want a diamond lathe mesh instead but nice u can go right over it.

Thank you for the video thumbs UP.
Richard Maunder thank you sir. 👍
Appreciate the informative video. Did you charge extra for the tree parging at 15:20 ? 😃
Nope that was free of charge. Lol 😆 🤣
You ever try a paint roller thick nap for scratch coats? Think it goes on quicker and follow up with a trowel…. Not for parging but for a scratcher…
I like that idea I will have to try it. Thanks 👍👊😊
How quickly should second coat be done? Can it be delayed for a week or two?
Do you need to put on peel and stick before putting the mesh into the sticky material you mixed up?
We usually do the peel and stick on the below grade area first then the parge after.

I have done this to ICF walls before and no synthetic mesh needed.

Polaris Fusion. Hi both the screen mesh and the prep coat are made by Nudura. You can buy them from any Nudura distributors. 👍👍

I have an ICF wall foundation to parge and the way the house is built, the bottom of the foam board insulation overhangs the foundation and siding is attached to that.

I would use a flashing detail I am thinking.
Here in Alaska the Nadura distributors don't have this product. 😐 What could be another option for something that fine? We used the rubber membrane for below grade stuff. But this is for the shop above the slab. So about 6 inches.
Check into a product called Dryvit Stucco. It's the same thing as Nudura prep coat.
Do you over lap the corners with the mesh bud ?
Clive HD Homer. I would fold it over the corner a couple inches for best results 👍👍

I think a scratch coat and press the mesh into the parge. I have never done it over wood but this stuff is real sticky so its probably good.

Thinking of using nudura for pool walls. Wanting to tile the pool, would this product work underwater behind the tile?

We poured this short wall and floor and cut the holes at bottom
What’s the name of that product?
Nudura prep coat. You can also use a product called Dryvitt

Menards has 25' x 3' rolls of sticky side mesh for about $25 I'm not sure if that stuff works for what you're doing tho
Where would I be able to buy the parging materials for ICF forms.
Hi you should be able to get it anywhere that sells ICF blocks. 👍
Can you do the same with plaster on ICF walls?
Hi. Plaster will not stick good to ICF unless you mechanically fasten diamond lath and then plaster it as you would a concrete wall.
So what do you you if anything, below grade? TIA
We use a ruber stick on membrane or spray with closed cell foam. 👍👍
Good video man!
I’m looking to do this soon
I plan on attaching stone to the ICF blocks maybe I should use a metal lath type screen instead? What are your thoughts on this?
Use a metal lath and anchor into the ribs of the ICF the way he did this isn’t actually secured to anything
@@jesselytle7367I just have the bare ICFs is building paper AKA (Tyvek) required for shedding of water should it get behind the final surface? I’m going to make my own Stacked Stone
There’s nothing on youtube showing this process
Surprises you dont install a substrate of housewrap and tar paper under the mesh first to allow for water to eliminate behind the parging finish
Below grade we use a membrane or spray foam for water prevention.
Maybe try a tripod for your camera so I am not barfing by the time the video finishes.
Thanks
