I just ordered a 5 gallon container of the above from Home Depot.

(They don't stock it but it's free delivery)

I am building a room in my basement where I used to have an unfinished darkroom.

Though my basement is generally dry, I figured it would be a good idea to water-seal the brick walls. (House was built in 1898 so these are actually bricks and not cement block.

The product specifically states that it can be used on concrete, masonry or composite but makes no mention of wood.

Since I am putting in a plywood floor I was going to use sealer on both sides and am wondering if this product is satisfactory.

Thanks for any input.

Curious so I googled it:

Says it is OK but may not last as long and requires multiple coats.

My basement is dry too and I put up some framing on partially exposed to outside side and put down polyethylene sheet first for vapor barrier at the advice of a friend who did part time construction.

Thank you.

In the 38 years I've lived here, water only got in the basement one time...and it was not much so I guess this is not a major concern.

I might give it a coat of Eagle seal and when it dries, give it a coat of oil-based paint too.
