Vapor-reducing sealer for concrete / brick?
My house is in zone 3, marine/coastal, on the water, so really humid much of the year. The house is on pilings with the ground level a concrete slab with a single wythe of brick infill in between the pilings. I have a ~500’^2 workshop area I’d like make reasonbly dry for tools, etc.
What would be the appropriate sealer to apply to the concrete floor and brick to help reduce the water vapor transmission up through the concrete floor and from the outside air/rain through the brick?
