Anybody out there tried the concrete sealant product called 'DryLoc'? It's one of a number of concrete sealants I'm considering using to prevent water vapor from ruining the carpet of a residential home. If the carpet is covered for a period, w/ furniture or whatever, it becomes perceptably damp- not soaking wet, but just barely damp. Concrete sealant has been recommended to fix this problem, but I don't want to do all that work if the product won't work, or only lasts a few years. And that's my post.

You may have already found an answer.

I bought a brand new house and in the basement I will put in a bathroom. I also did not want a moisture issue so I bought Drylok masonry waterproofer. There were not many choices at the store but reading the can this looked like just what I needed. I put on 2 coats like the can said and it dried with a very gritty sandpaper-like finish, onto what was a very smooth concrete floor. I contacted the maker, UGL. They said that stuff is not intended for floors, it's for walls. True the can did not use the word floor for it's uses, but also did NOT say it was not good for floors. THe good part is that the rough surface is going to have a floor built over it anyway so it wont matter. So you should be ok to use it too. I just will have to find something else to paint the part of the basement floor that will not be finished into rooms.

I don't particularly care what the surface will look like, since it will be covered w/ carpet padding & carpet. Did the product stop moisture from coming through the floor? I guess if you didn't have a problem to begin with, there's no way to know. Have you heard anything to lead you to believe it WON'T repel moisure? Thanks for the reply. This project is sort of on the back burner, pending more info.

I can't say how it performed stopping moisture because, well I just dont have any coming through anywhere on the floor, including the areas not painted. But it is now November and the weather is dryer anyway. I put it down to prevent it from happening, in case it would have if I didnt use it. As you know, once that living space floor is created, for all that money spent, I dont want moisture coming through. So I painted it just to be safe.

I've heard nothing to say it does not work. The good part for you and I - it's tough stuff made by a reputable company and I assume performs well, and we dont care about the finish since it will be covered.

Both my sons have used the product in their basements. One has more of a moisture problem than the other. It was a bit of work to apply with a large course brush, but it dries like iron. It's made in Scranton, PA by Gilsonite Labs.

Another thing you might look into is a silicon type spray for masonry. I have done that to basemtnts that I was finishing off, and the pores are sealed up and water beads off like the floors are greased and will not soak in. It also seals the pores so that the mositure will not wick up from below. Sherwin Williams makes a good masonry sealer, or Thompson Water Seal is excellent too. Watch out for the fumes, open the house up. YOu will need a paint respirator to protec t you from the fumes, but the stuff will work and there is no build up on the floor or walls.

I have stone foundation walls that I want to treat w/Dryloc and then painting. How well do Dryloc'd stone walls take paint? It sounds like the treatment leaves the walls kind of rough.

It leaves them very rough. But rough surfaces accept paint better. So it's a matter of what kind of surface you want once your final coat of regular paint is done. Personally, I would not want this Drylok exposed at all in any area where people will be. Somebody rubs against it too hard and there goes their skin. I imagine multiple coats of that paint will smooth over the Drylok's rough finish but who knows how many it would take.

As a paint contractor, I have used Dry Loc hundreds of times. This product CAN be used on floors. The company states that it is not intented for this, but I use it everyday. My own home that I had built in 1998 was 3200 sf. with a 980 sf basement. I told the contractor to lay a double vapor barrier down, for I wanted to Epoxy the floor; he didn't! I had 1" of water the first heavey rain, that had hydrostaticly came through the floor. I applied 3 coats of LATEX Dry Loc to the wall and floor. After full cure, I did a moisture test (take a 12"X12" piece of plastic and tape it tight to the floor on all edges and leave it for 48 hours) and the results were great.

The reason they say it is not intended for floors is that 1). It will wear off in time (along time). and 2). It is very ruff to the touch (thats the portland powder cement in the mix).

I also have had water in a new addition and checked everywhere and everyone to find the best waterproofing for the concrete. I even had a concrete expert come over to advise. After finding many choices online but not wanting to pay the expensive shipping charges, I decided to use Dry Loc, BUT! Before I painted the walls and floor seam, someone let me borrow their dehumidifier. WOW!!! All this time that the rain and high watertable were being blamed for the moisture, it turned out to be nothing but condensation from high humidity. After running the dehumidifier for a few days, ALL the water was gone! Now the Dry Loc has been applied and looks super. Time will tell.
