Stain Block PS

Invisible penetrating stain blocking masonry sealer for POROUS SURFACES

Overview

GST International's Stain Block PS masonry sealer is a state of the art water and stain resistant penetrating sealer specifically designed for dense concrete, brick and masonry surfaces. When dry it is virtually invisible, leaving the surface with its original appearance and breathability. It resists oil and grease stains, rust stains, moss, mildew and spalling problems associated with freeze/thaw cycles. Stain Block PS masonry sealer provides superior protection against moisture penetration, thereby reducing the formation of efflorescence.

Stain Block PS masonry sealer chemically bonds with the silicates present in the substrate surface, forming an insoluble barrier that cannot wear away, fade, yellow, crack or peel. It is highly alkaline resistant and designed for use on dense surfaces such as; marble, granite, limestone, travertine, polished or tumbled stones, concrete, brick, pavers, slate, precast concrete, tile and cultured and natural stone. It's easy to apply, fast drying, and can be applied even in cold or damp conditions. Commonly used in both commercial and residential applications, i.e.: eating, food preparation and serving areas.

LIMITATIONS: Will not resist moisture where hydrostatic pressure is active. Do not use as a pre-grout sealer. Once installed, this product is not removable.
