How to waterproof Leaky Tie Rods in basement walls using the RadonSeal® DIY Crack Injection Kits (urethane). 1. Glue a surface port over the hole. 2. Fill the empty cartridge (included) with water. 3. Insert the cartridge into the caulking gun and inject the water into the surface port. 4. Insert the urethane cartridge into the caulking gun. 5.

Customer Inquiry – Brick Backsplash "Hi. I am using thin brick as a kitchen backsplash. Would this [LastiSeal] work to seal the bricks to help with splatters behind my range?" - Brandi, OK RS: LastiSeal® Brick & Masonry Sealer will work only if the brick you are applying it to is porous. The composition of brick and stone veneer varies so it always best to test the product before applying to the whole surface. If the sealer is absorbing well and not leaving a film behind than your good to go!
