Product #40 Silane Penetrating Sealer is a clear, one (1) component sealer that provides excellent protection to concrete against attack from wet/dry, freeze/thaw cycles, and de-icing chemicals. PRODUCT #40 provides a hydrophobic "water-shedding" effect to masonry surfaces. PRODUCT #40 is a penetrating sealer that is repellent to liquid water but permeable to water vapor: a "breathable" sealer.
WHERE TO USE: PRODUCT #40 is used to protect bridge decks, roadways, parking garages, parapet walls, brick work (clay and lime sand), timber wood and mortar.
PROPERTIES: PRODUCT #40,
tested in accordance
with NCHRP Report # 244, produces the following results:
Surfaces must be clean, sound and dry. If some moisture is present in the
concrete or masonry, it will not
affect the performance of PRODUCT #40. However,
the drier the surface, the deeper the penetration.
PRODUCT #40 may be applied by spray (using hand-pumped pressure sprayer),
brush, roller or dipping of masonry units. For best results, use hand-pressure
spray equipment. For best results on most concrete or masonry surfaces, two (2)
applications are recommended. Dense new concrete surfaces may only require one
150 to 250 square feet/gallon, depending upon concrete or masonry porosity. If
two (2) applications are required, second (2nd) coat may be applied immediately
after first (1st) is fully absorbed.
PACKAGING: One (1) gallon, five (5) gallon and fifty-five (55) gallon drums.
LIMITATIONS: Do not apply on or through standing water. Material is not intended to seal moving cracks from moisture intrusion. PRODUCT #40 is not to be used to prevent leaks from hydrostatic pressure. Do not apply at surface temperatures below 45? F, or when surface temperature is expected to fall below 45? F within four (4) hours after application. If material is to be stored after initial opening of container, be certain container is closed airtight.
CAUTION: COMBUSTIBLE! Contains hydrocarbon solvent. Avoid inhalation of vapor. In case of contact, immediately flush eyes or skin with plenty of water for at least fifteen (15) minutes. Call a physician in case of severe skin or eye irritation. Wash clothing before re-use. Discard contaminated shoes. Wear protective clothing, goggles, and/or barrier creams.
