Penetrating Water & Salt Repellent Iso-Tek™ 8540
At 55% actives, this breathable silane sealer provides long-lasting protection against moisture, freeze-thaw cycles, and intrusion from water and chlorides.
Easily applied with a sprayer, roller or brush, the 8540VOC can be used on a variety of poured concrete, brick and masonry applications. Can be used on interior and exterior substrates, on new and old concrete and is an excellent choice for nearly any substrate that needs water repellency.
Provides a flat, natural finish. Treated concrete will not change in appearance, color or texture. The proprietary nanotechnology offers deeper penetration when compared to traditional silane isomers resulting in an even longer service life. Provides excellent adhesion when used as a primer for paint or coatings.
