LL10 & LL20 Water Repellents
LL10 & LL20 Clear Siloxane Masonry Sealants
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
•Prevents concrete corrosion by blocking salt penetration
•Effective protection, even in wind- driven rain
•Reduction of salt blooming
•Normally, no visible change of surface

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.

Preparation & Application
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.
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 40°F and rising. Examples of application fields:
•Stucco, brick, terra-cotta
Apply at a rate of 125-175 square feet per gallon.
Caution/Care of Tools
Do not apply when rain is imminent. Protect from freezing. Coating must be dried before exposure to water. Store in a heated room and keep container covered when not in use. Do not thin. Cover air intakes during application and while drying. Keep out of reach of children. Avoid prolonged contact with skin. Wear protective eye wear. Dispose of in an environmentally safe manner. For additional information refer to the MSDS sheet. Do not store material at extreme temperature, below 32°F (0°C) or above 125°F (50°C) for any length of time. KARNAK #LL10 (and #LL20) has a shelf life of 12 months from date of delivery when stored in unopened containers at room temperatures.
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.
