LL10 Aqua-Repel Dampproofing and LL20 Aqua-Repel Dampproofing
Karnak #LL10 & LL20 are environmentally friendly colorless silane modified siloxane emulsions manufactured for use as masonry water repellents. They are formulated for deep penetration which enables surfaces to shed water effectively.
The active material penetrates into the substrate and condenses to give hydrophobic characteristics to the substrate. The reaction does not substantially affect the water vapor permeability of the treated surfaces.
Karnak #LL10 & LL20 are water repellents designed specifically for use on fresh concrete and similar alkaline substrates. Neutral substrates will require longer curing times to develop similar water repellent characteristics.
- Fed Spec SS-W-11OC
- NCHRP 244 Series II
Application of the Karnak #LL10 & LL20 solution should be made onto a clean, dry surface free of oil, grease, dirt, laitance and adhesion-inhibiting materials.
Apply at a rate of 125-175 square feet per gallon.
Karnak #LL10 & LL20 (stir before using) can easily be applied by brushing or spraying until the surface is saturated. Full curing requires 7 - 10 days.
Apply the solution by starting at the top of the structure and working downward. Avoid rundown or drips.Application should be made at temperatures of 40Â°F and rising.
Examples of application fields:
- Pre-cast concrete
- Bridges Clay tile
- Field stone
- Stucco, brick, terra-cotta
CARE OF TOOLS
Tools and other equipment should be thoroughly cleaned with soap and water immediately after use. Mineral spirits may be needed for clean-up if tools are allowed to dry, taking necessary precautions when handling combustible materials.
|VOC (ethanol by reaction)
- Prevents concrete corrosion by blocking salt penetration
- Water repellency
- Effective protection, even in wind-driven rain
- Good penetration
- Reduction of salt blooming
- Non-tacky finish
- Normally, no visible change of surface
- Prevents spalling
