sealing out water in new garage
I have been slowly converting my carport over to a garage as time/money permits. A local handyman and his helper put up the most of the walls about a month ago. They have 2*4's on screwed into the cement floor, the studs attached to those which are connected to the existing ceiling walls. The walls are covered with plywood (t1-11 I think?). The 2*4's on the ground have plastic barrier between them and the cement floor. On the outside the contractors placed liquid nails for a water barrier, but I have found that is not enough and water leaks in during good rains. Over the past 2 weeks I have been putting down more and more liquid nails and when it rained thursday I happen to be home and noticed the Liq nails seem to help on one wall , perhaps a bit on a second, and not at all on the third. Yesterday, I went out to put out yet more nails on the wall that is still leaking and a contractor working next door saw me and in talking mentioned that Liq nails is not a good water sealer. He mentioned that silicon cement sealer would be a better choice and also perhaps a gutter in front of the wall( I had already been thinking of the same thing, only something like a vinyl "L" if they make such a thing). After that I went to lowes to look for such a sealer and found these 2: GE siding & trim-modified silicone polymer and PL Polyurethane concrete crack and Masonry sealant. I also picked up a 1*2 cement board that won't rot and thinking of sealing this in front of the wall as a trim Piece that also blocks the water. The contractor was gone when I got back home so I have no idea if what I have is the right stuff. Does all of this sound doable?
