Health Precautions

MAY BE HARMFUL IF SWALLOWED. MAY IRRITATE EYES AND SKIN. Wear skin and eye protection. Contains potassium hydroxide and potassium methyl siliconate. If in eyes, flush with water for at least 15 minutes. If on skin, wash with soap and water. If irritation persists, seek medical attention. If swallowed, DO NOT induce vomiting and seek medical attention. Keep out of reach of children.

Pre-Grout Sealer/Grout Release

Porous tile, such as clay and Saltillo pavers, can be stained by grout during installation. Sealing the tile before grouting will make grout removal much easier. Apply two coats of sealer according to directions after tile has been bonded for a minimum of 24 hours, or apply to front face of tile before installation.

Application of Product

USE CHEMICAL-RESISTANT GLOVES, such as nitrile, when handling product.

Surface should be clean, dry and free of any waxes or finishes. For new installations allow grout to cure 48 - 72 hours. Unscrew cap and remove seal. Apply liberally to grout joints in even coats. Allow to penetrate 5 minutes. Wipe off excess. If absorbed, apply a second coat. Surface is sealed when sealer no longer penetrates. If residue is visible on tile surface, remove with water and sponge or white nylon pad 60 minutes after application.

Drying Time

2 - 3 hours.

Cleaning of equipment

Clean tools and hands with soap and water immediately after use.

Product Maintenance

Do not use cleaners containing ammonia, acids or bleach. Use an appropriate TileLab® or Aqua Mix® neutral cleaner. Tile industry experts recommend periodic testing of sealed surfaces. Apply a few drops of water on the surface. If it soaks in, a coat of TileLab® or Aqua Mix® sealer will be necessary to keep sealer at peak performance.
