Cinder/Concrete Wall Sealer for Studio

Hello!
I work at a sound studio and we're close to finishing work on a new and exciting wing of the facility.
The wall in question is concrete or cinderblock and we've chosen to leave it exposed for a design esthetic (see picture). It occurred to me though that it probably needs sealing, but this is very foreign territory. It should probably be sealed enough to prevent moisture from getting into the room (which will have computers etc in it) - but we prefer keeping it natural in look, so a clear product is ideal. Plus as we're keeping the old studs in place, painting with a clear substance will be MUCH easier. We're assuming that this is also the other side of the exterior wall.

What products should I go for and is there any sage advice I can get on this endeavor?

Thanks!

Welcome to the forums!

What is on the other side of the block wall? Usually it's best to do the waterproofing on the exterior side. I don't know of any effective waterproofing coatings that are clear but I suppose a couple of coats of a water based poly would seal the block as far as dust goes.

Thanks Marksr - I'm assuming the exterior side is sealed. It's on the second story of our building, and it painted. It doesn't seem damp in the room, and there's no moldy smell either.

I found this stuff on home depot, seems like a good bet and people love it: Seal-Krete 1-gal. Original Waterproofing Sealer-100001 at The Home Depot

I don't think I've ever used that product but suspect it's similar to Thompson's WaterSeal. Generally for TWS to be effective it has to be applied liberally [where it runs down the wall as it soaks in] It won't leave a finish that you can see - dries flat and should look like nothing is on the wall.

If that room is part of a sound studio, how can you possibly leave it like that? The sound will bounce off of that thing like a rubber ball?

Valid concern Pulpo!
That wall is for the control room, where you edit and run the recording system for Foley/VO for the attached booth. The entire room with have sound treatment and a cloud system of sound panels. This wall will be what the engineer faces, speakers pointing away from. Each one will have a small halo of sound panel, and there will be small panels and bass traps in places between some of those studs. There are many pro studios like ours with exposed brick etc, you just have to offset them.
The new foley room though, is covered almost floor to ceiling with sound proofing.
