Universeal Rapid All-In-1 stain stop impregnator sealer is a premium solvent-based product that offers excellent stain protection against oil and water spills. The unique formula of Universeal Rapid All-In-1 stain stop can be applied to damp stone and grout immediately after installation. No waiting around, saving time & money with this unique fast track formula.
Rapid All-In-1 stain stop penetrates to protect polished porcelain and all types of natural stone surfaces, i.e. travertine, terracotta, limestone, marble, granite, sandstone and many other porous stone surfaces against oil and water-based stains.
 
Before application make sure the surface is completely dry, clean and free from debris.
Apply an even coat of Universeal Rapid All-In-1 stain stop to the surface and edges of the stone using a solvent resistant sprayer, lint free cloth or brush. Ensure even distribution by wiping over several times, remove any surface sealer that has not penetrated the tile or stone after 15-20 minutes.
Apply a second coat of Rapid All-In-1 stain stop, allowing 30-45 minutes drying between coats, repeat the process and remove any excess sealer from the applied area with a dry lint free cloth. It will take up to 24 hours before the product will offer full protection. Until this has happened, keep the surface free from water and oil spills, as stains may occur before fully cured.
