Siloxane Water Repellent

WR-10 SILOXANE WATER REPELLENT 23-10X

 

TUF-TOP " WR-10" is a solvent based siloxane water repellent designed to render water repellency to old and new masonry. It provides a long lasting, breathable barrier which exhibits excellent resistance to water, airborne dust and dirt, acid rain, salt, efflorescence, and freeze/thaw damage and spalling. The water repellency of WR-10 does not allow the substrate to retain moisture and therefore prevents growth of mold and mildew. Also available in %, 15, & 17 % Solids Concentrations.

Preparation:

Surface to be coated should be clean, porous, and dry. Remove all dirt, grease, oil, wax, mildew and excessive chalk and surface and all efflorescence from the surface. High pressure washing is recommended to remove dirt and open up the pores of the concrete. Reasonable effort should be made to repair all loose or missing mortar, flashing, vapor barriers, expansion joints etc.....

Application:

Surface to be coated should be clean and dry. Apply by flood coat, using a low pressure airless, pump up sprayer or power roller. DO NOT ATOMIZE. Best results are obtained when the product is applied in the form of droplets rather than mist. Surfaces must be " flooded/saturated ", allowing the material to run down 6 to 8 inches from the point of application. Vertical block and brick must be saturated with the material at the proper coverage rate in one coat, or two coats wet on wet. This product rely's upon penetration depth for performance. The deeper the penetration, the better the performance. If the material is not applied at the proper coverage and is allowed to dry, it must be re-applied at the proper square footage, and not " touched-up" with the missing amount. Always work from the bottom up to insure complete coverage. Two coats are generally recommended, depending upon surface porosity.

Limitations:
  • Not for use on the following : marble, limestone, or other forms of calcium carbonate. May inhibit over-coating.
  • Will not "bridge" cracks or spaces wider than 0.2 mm. Do not apply at temperatures below 45 degrees Fahrenheit.
  • WR-10 will not inhibit water penetration through cracked, or unsound surfaces, or surfaces with defective flashing, caulking, or structural water proofing design.
Drying Time:
  • TO TOUCH - 3 HOURS
  • RECOAT - OVERNIGHT
  • FULL CURE - 7-10 DAYS
