Water-Based Concrete Cure Membranes and Sealers

Dow Construction Chemicals offers water-based concrete sealers and cure membranes.

Sealers are typically applied to fully cured concrete. They can provide gloss, stain resistance, long-term UV and water durability, and hot tire pick up (HTPU) resistance.

Cure membranes are applied to fresh concrete (usually within two hours) – to retain water and hydrate Portland cement in certain situations. It is acceptable for cure membranes to wear off after 28 days of service.

For cure and seal applications, the product initially acts as a cure membrane. It also must offer performance benefits such as long-term UV and water durability and HTPU resistance.
