Generic Type

Modified Siloxane with Diffused Quartz Carbide

Common Usage

Prime-A-Pell N.S. (natural stone) is a clear, filmless, penetrating water repellent for virtually all above-grade, vertical concrete and block and brick masonry and vertical and horizontal installations of natural stone. Concrete, natural stone and masonry treated with Prime-A-Pell N.S. 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.

Volatile Organic Compounds

6.1 lbs/gallon (727 grams/litre)


Prime-A-Pell N.S. is a clear liquid when applied but dries clear, leaving the aesthetic appearance of the substrate unchanged.

Curing Time

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.


If color is desired, apply Series 607 Conformal Stain.
