Safecoat Grout Sealer is a clear, moisture resistant sealer for porous tile grout and other cementitious surfaces. It actually reacts with and becomes a part of the grout, increasing water resistance and minimizing the penetration of liquids, helping to prevent staining and giving a wearable, washable surface. Like all Safecoat products, it is as safe and not toxic as possible, formaldehyde free and virtually odorless, giving off no offensive chemical fumes. Dries clear without discoloration.
USE ON - Unsealed tile grout. May also be effective on a variety of other porous cementitious surfaces (test first). For previously sealed grout, conduct several small test patches for absorption and compatibility.
APPLICATION - Always have adequate ventilation. Apply to grout liberally and in an even manner, using a sponge, dry lint-free rag, small brush, or any other tool which can be used comfortably. Flood coating is acceptable, but avoid puddling and to wipe off tile. One coat is generally sufficient. IMPORTANT - Wipe off any sealer which has not penetrated into the grout within 10 minutes; do not allow sealer which has not soaked in to dry on the surface (simply wipe off with a slightly damp cloth or sponge). Always test a sample for suitability prior to full use. Note - these instructions are intended to be general only and not exhaustive. The applicator should determine what preparation and techniques are best suited to the specific surface. See product data sheets for most current information.
COVERAGE - Variable depending on method of application and surface porosity. Generally one quart will cover a minimum of 75 square feet of standard grout lines. Do not thin.
DRYING/CURING TIME - Under normal conditions, Safecoat Grout Sealer dries to the touch within one hour and cures within 24 hours. Normal conditions include a clean, dry surface, access to fresh air flow, a dust free environment, moderate humidity, and temperatures above 55 degrees F. Thick application, high humidity or conditions other than normal will cause Safecoat Grout Sealer to dry and cure more slowly. Avoid using sealed surface for at least 24 hours after application.
