| USES 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.
SPECIFICATION
- Fed Spec SS-W-11OC
- NCHRP 244 Series II
SURFACE PREPARATIONApplication
of the Karnak #LL10 & LL20 solution should be made onto a clean,
dry surface free of oil, grease, dirt, laitance and adhesion-inhibiting
materials.
COVERAGE RATEApply
at a rate of 125-175 square feet per gallon.
APPLICATIONKarnak
#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:
- Facades
- Pre-cast concrete
- Roadways
- Bridges Clay tile
- Field stone
- Stucco, brick, terra-cotta
CARE OF TOOLSTools
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.
