Dur A Pell 40
Generic Type
Silane
Common Usage
Dur A Pell 40 is a clear, filmless, penetrating water repellent for virtually all above-grade, concrete, stucco, natural stone, block and brick masonry. Concrete, stone and masonry treated with Dur A Pell 40 resist water intrusion, stain damage, freeze/thaw spalling, efflorescence and rust damage. The treatment does not alter the color or texture of the surface, nor significantly affect the vapor transmission qualities of the substrate. The solution penetrates the substrate and chemically reacts to create a powerful barrier against water penetration. This barrier is resistant to ultraviolet and weather deterioration.

Curing Time
Dur A Pell 40's volatility increases with temperature, therefore more material will evaporate from the treated surface prior to curing when temperatures exceed 80°F (27°C). Protect treated surfaces from rain and lawn sprinklers for 6 to 8 hours. (Time to resist moisture is increased at lower temperatures). Allow 7 days before evaluating performance.
