Water-Based Acrylic Adhesive
CLAY-TITE ADHESIVE is a water-based, acrylic adhesive containing emulsified bentonite. It is easy to apply using a trowel or putty knife. The product bonds strongly to various substrates, including concrete and waterproofing membranes, such as CLAY-TITE from W. R. MEADOWS.
CLAY-TITE ADHESIVE is used to fill cracks and voids in walls and pipe penetrations, to fill inside corners between vertical and horizontal transitions, to fill voids and adhere WATERSTOP EC from W. R. MEADOWS to construction joints, and to seal joints and overlaps in applications of CLAY-TITE. CLAY-TITE ADHESIVE forms a strong adhesive barrier, helping create a seamless installation for these products. For installations with shotcrete or lagging, CLAY-TITE ADHESIVE protects CLAY-TITE from damage caused by this type of application.
- Easy to apply.
- Bonds strongly to various substrates.
- Ensures a complete, seamless CLAY-TITE waterproofing installation.
- Also compatible with WATERSTOP EC.

WATERSTOP EC SURFACE PREPARATION … Surface must be free of all debris and standing water. Dusty, damp, or uncured surfaces are suitable for application.
WATERSTOP EC APPLICATION METHOD … On smooth surfaces. Apply a bead at 1/8″ – 1/4″ (3.2 – 6.4 mm) along the joint. On non-smooth surfaces, knock down protrusions greater than 1/2″ (12.7 mm) and use CLAY-TITE ADHESIVE to fill voids. Apply WATERSTOP EC into uncured CLAY-TITE MASTIC and nail every 15″ (381 mm) o.c. with powder-actuated or hand-driven concrete nails (1″ or 2.54 cm shank) with washer (5/8″ – 13/16″ or 15 – 23 mm). Butt ends and fill gap between adjacent pieces for a continuous application.
Cleanup … Use soap and water on uncured material.
Protect from moisture. Do not freeze.
