Dayu sausage polyurea sealant Concrete Sealer creates a top coat that provides a durable, chemical, impact and abrasion resistant surface suitable for a variety of interior or exterior applications with an expected longevity of 3-5 years depending on traffic, conditions and location.
Surface must be structurally sound, clean, dry, and free of oils, grease and other bond inhibiting contamination. Failure to adequately prep the surface could result in the product delaminating from the surface.
Release agents, efflorescence and curing compounds must be removed from the surface prior to application.
Concrete surfaces should be profiled to at least a 200-grit level or should readily absorb water before applying to ensure good mechanical bonding. Older, weather eroded concrete is not a good candidate for this product. This product will become slippery when wet on smooth-finished outdoor concrete.
Applying to hot concrete surfaces 85-90F or above, such as a patio in the sun, will result in premature drying and a poor finish. To avoid a milky or cloudy appearance, do not apply to damp concrete or use wet applicators. Do not apply in periods of high humidity or when precipitation is expected during application or drying time is complete.
If uncertain about water vapor emission particularly in a basement, perform water test by firmly adhering plastic to the concrete and evaluating for condensation. Do not apply if condensation is present on the underside of the plastic.
