A ready to use formula that will provide ongoing protection against stains caused by algae, mildew, mold, and other organic growth from, roofs, decks, fences, siding, walkways, and other exterior surfaces.

The active ingredient is Tetraflex 50, a reactive silane. It has the ability to crosslink with itself and with the substrate, (i.e. a roof) to form an extremely large molecular weight cross linked, polymer barrier that is anchored to the substrate. The polymer barrier is formed in place, on the surface, and provides a durable, repellent barrier coating.

It is safe for cedar, redwood, treated lumber, asphalt shingles, concrete, stucco, brick, pavers, vinyl, patios, fabrics, canvas, nylon, cotton, and virtually any other surface. The invisible stain barrier is effective for up to 2 years. Reapplication should be made at the first sign of stain reappearance.
