S-40 WATER REPELLENT SEALER
FOR POROUS CONCRETE AND MASONRY
2
Form: GDH-571
Rev.: 120619
PRODUCT APPLICATION (cont.)
COVERAGE
One saturation coat is normally sufficient for vertical, smooth
dense concrete or masonry. For textured or horizontal
surfaces a second coat may be required. A second coat can
only be applied while the first coat is still damp. The
coverage rates listed are approximate and for estimating
purposes only. The surface texture and style of mortar joints
can greatly affect application rates. Always apply material to
test area prior to general application to establish spread rate.
LIMITATIONS
OKON S-40 does not provide protection against hydrostatic
water pressure, efflorescence caused by interior moisture
sources, or moisture penetration through cracks in mortar,
expansion joints or junctures between dissimilar materials.
S-40 will not fill large pores, bridge cracks, seal inaccessible
areas, or compensate for flawed construction. Do not use on
glazed or sealed surfaces. Do not tint. A mock-up should
always be performed and approved by property owner. To
protect more porous substrates when RILEM tube test
standards are required use OKON PLUGGER. Refer to
Technical Data Bulletin for detailed use instructions.
CLEAN UP
Clean hands and tools with soapy water. Clean drips, runs
and over-spray residue while still wet, using detergent and
water. S-40 will not etch common glass but spills and over
spray onto glass should be removed with a damp cloth while
wet. Dried material may require mechanical abrasion to
remove. Clean application and spray equipment with
detergent and water immediately following use.
