.PRODUCT APPLICATION (cont.) .
LIMITATIONS
OKON W-1 does not provide protection against hydrostatic water
pressure, efflorescence caused by internal moisture, or moisture
penetration through cracks in mortar, expansion joints or
junctures between dissimilar materials. W-1 will not fill large
pores, bridge cracks, seal inaccessible areas, or compensate for
flawed construction. Do not use on glazed or non-porous
surfaces. Tinting OKON W-1 is not recommended. Application of
W-1 may slightly darken the color and over application may build
sheen on the surface. A mock-up should always be performed
and approved by property owner. To protect more porous
substrates like CMU, rough stucco and blasted concrete, use
OKON W-2 or OKON PLUGGER. Refer to Technical Data
Bulletin for detailed use instructions.
CLEAN UP
Clean hands and tools with soapy water. Dried spills can be
removed using a strong solvent within 24 hours after application.
After that time sanding may be necessary.
