Steel Chemicals' Water-Guard for Stone

This is a slightly opaque, water-based stone waterproofing product. It is designed to penetrate all stone, brick, pointing and render and leave an invisible waterproof coating to prevent rain penetration. It can also be used as part of the external wall coatings for flood protection work, providing resistance to water entry into houses.

Notice especially the gap filling qualities of the formulation, stopping water from entering a really quite large gap. Imagine this product protecting brick and stonework on the outside of a house! No water entry into the external masonry means a dry wall that does not then draw heat from inside the house as the wall dries out. Dryer houses are warmer houses for the same amount of heat input.

Seven days after application the stone surface will be oil repellent.
This makes it possible to coat driveways, or areas in industrial situations, where contamination of surfaces by oil may be a problem.
The product has been independently tested by Vinci Technologies who have certificated the product as withstanding 8 bar (120 psi) of hydrostatic pressure whilst remaining 40% vapour permeable.
This product can be used to protect any external walls from weather penetration and also has excellent salt prevention properties where chlorides are a problem.
Stone Water-Guard is perfectly safe to handle and needs no hazard markers on the drum.
