Product Description

Sure Klean® Weather Seal Natural Stone Treatment WB is an odorless, water-based solution of potassium methyl siliconate developed to effectively treat a wide range of natural stone

and masonry surfaces. Natural Stone Treatment WB is a low VOC treatment that provides long-lasting repellency without altering the natural appearance of the substrate.

Natural Stone Treatment WB is used as a surface treatment on natural stone and masonry surfaces to impart a water-repellent surface and reduce water absorption into the substrate. Unlike conventional siliconate water repellents, Natural Stone Treatment WB has been developed to help prevent surface staining during application.

Application

Before applying, read “Preparation” and “Safety Information” sections in the Manufacturer’s Product Data Sheet for Weather Seal Natural Stone Treatment WB. Refer to the Product Data Sheet for additional information about application of Weather Seal Natural Stone Treatment WB. Do not dilute or alter.

Vertical Application

Spray

1. For best results, apply Natural Stone Treatment WB in a thin single saturating coat to a thoroughly dry surface.

2. When spraying, saturate from the bottom up. Use enough to create a 4" to 6" rundown below the spray contact point.

Brush: Minimize overlap. Saturate the surface. Brush out heavy runs and drips that do not penetrate

Porous Surfaces: Let the first application penetrate the masonry surface. Resaturate within 5 to 10 minutes. Less material will be required on the second application.

Dense Surfaces: Saturate in a single application with no rundown. Back roll any runs or drops to ensure uniform appearance. One application is usually enough.

Horizontal Application Instructions

1. Apply a single, saturating coat so that the surface stays wet for a few minutes.

2. Thoroughly broom out any pools or puddles that do not completely penetrate the surface. Do not let puddles stay on surface.
