Use-case
Water repellent for precast concrete facade panels
The problem
Facade panels take on rain, then fail freeze-thaw and stain. A plant wants a sealer that does not change color or block drying.
How it works
A silane dispersion soaks into the surface and reacts with moisture in the concrete, lining the pores so liquid water stays out while vapor still moves. Two spray coats. No film to peel.
