Escamas de epoxi para pisos - Caja de 10 libras para pisos de epoxi con escamas

Concrete looks solid. It isn't. Every slab is full of tiny connected pores, and ground moisture underneath it is constantly wicking up through those pores and evaporating off the top surface. You can't see it happening on bare concrete because the vapor just leaves.

Put a coating down and that changes. The vapor still arrives at the surface, but now there's an epoxy film in the way. Pressure builds underneath. Eventually it wins, and you get bubbles, blisters, or a sheet of coating that peels off in one piece with white powder on the back.

Contractors call it a coating failure. It's really a slab problem that the coating just happened to reveal.

Barrier performance is measured in "perms". Think of it as a leak rate. Lower is better, and the industry line for a Class I vapor retarder sits at 0.10 perms.

MVB Fast Cure 2:1 is formulated on an improved moisture vapor suppression chemistry that independent third-party testing that delivers perm ratings below 0.10 on properly prepared concrete. That's the chemistry underneath our product.

Here's the part most suppliers don't test for:

Adding color to a moisture barrier can wreck its barrier performance. Pigment particles disrupt how the film forms and can open pathways for vapor that weren't there in the clear version. It's a known problem in the industry, and it's the reason most moisture barriers ship clear.

So we had it checked. An independent certified third-party lab cast films of our pigmented grey formula alongside films of the neat clear reference system and ran water vapor transmission testing on both over seven days.
