Epoxy Floor Moisture Mitigation

Many flooring contractors have products available to use.

Epoxy floor moisture mitigation.

The epoxy mitigation product does not lock the moisture 100 percent from coming up through the slab but it slows it down to a rate acceptable for all flooring manufacturers to proceed with the new flooring products to be installed. Third crews apply primer over the epoxy and then self levelling underlayment ensuring a flat and dry floor. Once a moisture mitigating hydro epoxy is selected for application as the primer coat installation becomes a 2 day process at best. Laticrete recommends for protection against moisture vapor or when the relative humidity rh in the concrete measures 75 or greater to use laticrete vapor ban er or spartacote moisture vapor barrier as your base coat primer in all spartacote systems.

High moisture in the slab and associated moisture vapor transmission is one of the leading causes of resinous flooring issues and failures. Vaporsolve systems are used when concrete has a known moisture problem when concrete dries too slowly to meet the construction schedule and as a preventative measure when concrete doesn t have a vapor retarder. Proflex mb25 is a two component epoxy reaction resin based sealer for professional flooring installation over damp sub floors. Per 24 hours and in situ relative humidity rh moisture readings up to 100.

When applying the moisture mitigation system make sure that the concrete slab is strong enough clean. Two component hydro epoxies provide deep substrate penetration and mitigate substrate moisture problems due to hydrostatic pressure. If the any of the readings are high we select our moisture mitigating hydro epoxy as our primer coat. For terrazzo it is suggested to use a two part 100 solids epoxy system when possible.
