Sealing a Block Basement Options?

[fishfinder72]

I have a block basement that I am planning to finish off. Before I frame up and insulate the walls can anyone suggest a paint/sealant product to go over the block? Any input is appreciated. Thanks

There are numerous brands on the market. I picked up something at Mendards. I don't recall the brand off hand but it had a pretty lengthy against water penetration and mold/mildew growth.

I've never had water seaping throught the walls so I only used it as added insurance. Its only been on the walls for a couple weeks so I can't comment of long term effectivness.

Drylok Masonry Waterproofer is one I've used and had good luck with.

go with a 2 for 1 package and spray foam it.

Are you talking about something for waterproofing the block? If so, I would recommend one of the Thoroseal products. To get the good quality commercial line (I think they also have a consumer line) go to a contractor supply house like Brock White. Tell them what you have and what you are trying to accomplish and they can get you what you need. Thoroseal has been around since I started working back in the early 70's and has withstood the test of time.

Oh and be aware if there is active cracking in the block, you probably don't want a cementitious product like Thoroseal. The folks at B-W can set you up with something else that will work.

+1 on the advice to get info and product from Brock White.

Drylock...read the application instructions first before application
