Dur-A-Pell 20 is a clear, filmless, penetrating water repellent for virtually all above-grade, vertical and horizontal concrete, stucco, block and brick masonry and natural stone. Concrete, stone and masonry treated with Dur A Pell 20 resist water and chloride ion 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.
Clear. Dur A Pell 20 is milky-white when applied but dries clear, leaving the aesthetic appearance of the substrate unchanged.
If color is desired, apply Series 617 Conformal Stain WB within 12 to 36 hours after application of Series 636. Application of Series 617 outside of this time frame may compromise water-repellency and/or adhesion properties.
