Prep & Clean Floor

Clean the bare concrete floor by washing with clear water and sponge to remove all dirt and dust. When finished feel the area with your fingers for any loose grit left behind. If the surface is free of grit, move onto the next step. If not, repeat this step until clean.

Apply Adhesive

When installing the SquidGee Dry System, you will need one tube of SealOnce Adhesive per 4-foot 6-inch main section. Turn a main section over and apply a tall, thick bead of SealOnce Adhesive to the bottom of the main section. Turn the main section over and set in place.

Install Butt-Joints to Seal

Butt-joints make a seamless watertight connection at the critical joint between main sections. Apply SealOnce Adhesive on both sides of the seam. Hook the butt-joint at the bottom and "snap" in place at the top.

Easy to Install Pre-molded Corners

Easy Pre-Molded Corners

Install and seal our pre-molded inside and outside corners. No mitering corner joints. Seal the corner's edges and caulk the bottom for a leak-free bond.

Finishing Waterproof Seal

Caulk the floor joint with enough pressure to force some of the SealOnce Adhesive under the system. Follow by slicking down and feathering the finishing bead of adhesive using a cornering tool or your fingers.

Drain Water Away

Drain the SquidGee Dry System to your sump pump or floor drain using our 23" Drain Port Channel. Once installed, walls can easily be finished.
