How to fix a leaky wall crack
Basement wall cracks often leak water into the basement if gone untreated. You can fix a weeping wall crack with the do-it-yourself CRACK! waterproofing sealant. CRACK! seals with a tight, flexible waterproof hold.
- 1 to 2 tubes of CRACK! (depending on the size and amount of wall cracks)
- Putty knife
- Cylindar drill attachment to clean surface (also know as a wire power stripper)
- Air hose or can of pressurized air
Simply clean the surface with a drill attachment that is best described as a cylinder with infrequent coarse steal wires loosely nicking away at the concrete surface.
Then blow the surface clean with an air hose.
With the surface dry, squeeze a thick bead of CRACK! along the wall crack quickly followed with a 1-1/2” wide plastic putty knife, creating a 1/4” thick ribbon of CRACK! down the wall. If the leaking wall crack leads all the way down to the floor line, leave the bottom 3" of the wall crack open and install the SquidGee Dry System.
The next day most of the CRACK! will absorb into the pourus cement wall leaving a VERY tough 1/8” thick, smooth ribbon on the wall.
