Acryl Seal 25: Solvent Base

Acryl Seal 25 is a solvent-based alkylalkoxysilane penetrating water repellent. It is designed specifically for warehouse floors, brick masonry, limestone, pre-cast, and concrete surfaces, including blocks where darkening is unacceptable.

Acryl Seal 25 reduces bonding of airborne hydrocarbons, reduces water damage from freeze thaw, protects against efflorescence, and has excellent ultraviolet resistance.


– Protect all non-masonry surfaces.
– Treated surface should be free of dirt, grease, moisture, etc.
– New concrete should be allowed to cure at least 14 days before application.
– Product may be applied with low-pressure spray equipment, a brush, or aroller.
– When using low-pressure equipment, apply a light mist coating to break the surface tension; this allows for good penetration. Repeat the process with a flood coat (4 to 6 inches run down).


– Air and surface temperature must be above 40° F during application.
– Caulking should be installed prior to application.
– Protect surrounding non-masonry surfaces, such as glass, aluminum, etc.
– Inadvertent splash should be removed with water before the solution has dried on the surface.
– Do not apply when rain is predicted with 24 hours.
