Stem Wall needs Mortar to fir out ????

[CamarosRus]

Not a specific floor issue, but hoping concrete/floor experts here would help out.

My shop framing sits on top of my short stem walls. Interior is sheet rocked making the sheet rocked surface protrude out further than stem wall, by maybe 1/2" or more.

I'm thinking of installing FRP panels on top of sheetrock and then 6" ROPPE brand rubber base cove over the FRP and sitting (and chalked) to epoxy flake floor.

I need to build out stem wall so as it will be flush with sheet rock or FRP panels. Can you give me specific advice on what kind of concrete mortar or other product I can trowel flush onto the stemwall........all after drying
then use ROBERTS brand adhesive to bond the ROPPE coving to this new "mortared" surface.

I want to use the FRP panels in case I get lower part of walls wet in the future.
Fasten FRP to sheet rock with Heavy Duty LIQUID NAILS or ?????....

I'm asking for detailed advice as Ive never done this kind of work before

Thanks so much

Don't use mortar. Simply attach a piece of plywood the appropriate thickness to the face of the foundation to make it flush with the sheetrock. You can glue it on, shoot it on, or screw it on with tapcons.

Liquid nails will work but I have always used spray on contact adhesive.

Use PT plywood to shim the stem wall out even with the drywall, then use AZEK vinyl trim to make a lower kick board around the perimeter. Azek is water proof and doesn't rot or deform if it gets wet.

I need to measure in several places, but I'm thinking that the amount, the difference in offset is not consistant along the approx 45' of sheetrock vs stem wall. This is why I was thinking that "mortaring" (or ???) the stemwall to be flush with the sheetrock was
a viable idea ?

I need to search to see what AZEK vinyl trim is and what the size(s) are. Why do you not like a rubber base cove like ROPPE ?

Chuck, If you are handy with a trowel you could get a little silica sand and cement and mix your own. I've was doing this 30 years ago when parging foundations. A little bit of a modifyer would make it stick better. I think they still make acryl 60. It's not the greatest but just fine for a diy'r to make their own stuff. You could even get some colorants and make what ever color you want in the mix. Then you wouldn't have to paint it..... paint doesn't do well anyway. Get some clear sealer and seal it up well.

Gene, I havent investigated the product in person....but what would be so criminal about using 6" ROPPE (or ?? brand) Rubber Base Cove to cover flushed out stem wall.

Cove would sit on top of polyurethane epoxy chipped floor and extend up onto the sheetrock or possibly FRP.

I just need to learn what product would be the most cost effective, and easy to apply
for bring the stem wall flush with sheetrock. Maybe I should measure several misc places and see if cutting strips out of plywood could work ? What is PT plywood ?

Cost of AZEK trim boards for example are quite spendy. I was on AZEK web site and
couldn't find AZEK Vinyl Trim ???

Oh hell, I don't know. Having concrete in my back ground I always think that is the easiest. The vinyl cove base would be the quickest if you didn't have to do a lot of prep to get it up. The FRP is really thin and could show waves if the base isn't straight. They have a lot of trim stuff for it.

How high is the stem wall? If it's not too high perhaps you could just let the sheet rock float down towards the floor, then poke holes in the bottom of the sheetrock and squirt some of that expanding foam into the gap sealing everything off. After it sets up install the cove with adhesive. Just thinkin outside the box...........
