Limitations to the Product
When using over lightweight concrete or gypsum underlayment,
the surface must first be prepared with RedGard®Waterproofing
and Crack Prevention Membrane.
Donotusewhenthetemperatureisbelow50°F(10°C)orabove
90°F(32°C).
Do not use on sloped surfaces that require drainage.
This product is not meant for use as a wear surface.
Precautions should be taken when applying over post-
tensioned concrete, pre-stressed concrete or prefabricated concrete
planks. Contact CUSTOM technical services for further details.
Do not bond directly to hardwood, Luan plywood, particle
board, parquet, cushion or sponge-back vinyl flooring, metal, fiberglass
or plastic. Contact CUSTOM technical services for recommendations.
For installations over metal decks, contact CUSTOM technical services
for recommendations.

5 Instructions
General Surface Prep
USE CHEMICAL-RESISTANT GLOVES, such as nitrile, when
handling product.
All surfaces must be structurally sound, clean, dry and free from
contaminants that would prevent a good bond. Concrete must be fully
cured. Concrete surfaces should be primed with LevelQuik Latex
Primer. Smooth concrete surfaces, existing glazed tile, terrazzo, or
polished stone may need to be roughened or scarified. For increased
performance in demanding applications, concrete surfaces can be
mechanically profiled and prepared by shotblasting, sandblasting,
water-jetting, scarifying, diamond-grinding or other engineered
approved methods (reference ICRI CSP 3 standards for acceptable
profile height). CUSTOM's MBP Multi-Surface Bonding Primer may be
used as an alternative to profiling the surface.
Bonding to Concrete Surfaces
Contaminants or curing compounds should be mechanically
removed before installation. Concrete must be free of efflorescence
and not subject to moisture beyond the floor covering manufacturers'
limits or hydrostatic pressure. Lightweight concrete surfaces must have
atensilestrengthinexcessof200psi(1.4n/mm²).
Bonding to Plywood Surfaces
Plywood floors, including those under resilient flooring, must
be structurally sound and must meet all industry guidelines.
