Concrete Vapor Barrier Coating

This approach offers a simple roll on impermeable barrier on the inside surface of the concrete.

Concrete vapor barrier coating.

The good news is that it s still possible to apply decorative epoxy coatings to floors with high moisture vapor emission rates using a system of products from duraamen engineered products. Cmw 8000 moisture vapor barrier is a clear colorless spray applied penetrating lithium potassium silicate blended system designed to stop concrete floor coatings and floor coverings from de bonding due to hydrostatic vapor pressure coming up through a below grade concrete slab on grade slab and elevated deck slabs. Slab cote passes astm f 3010 13 moisture mitigation system for use under resilient flooring. Bostik slab cote extreme moisture vapor barrier coating is a single coat two component 100 solids epoxy formulated to dramatically reduce moisture vapor transmission and surface alkalinity from substrates.

However a big drawback of most epoxies is that they don t breathe and will trap moisture vapor coming up from the concrete slab. Bone dry original penetrating concrete sealer is a permanent low voc cost effective solution to protecting finished coatings from concrete moisture related issues and extending the integrity and life of concrete surfaces. It s hard to beat epoxy concrete floor coatings for their durability and abrasion resistance making them ideal for high traffic commercial applications. Ft 24 hours to 3 lbs 1000 sq.

It combines a primer and finish in a single fast drying coat and is specially formulated for manufactured housing facilities. It has 0 voc s as calculated per scaqmd rule 1168 low odor and is solvent free. Moisture vapor barrier primer finish interior latex is a coating designed to reduce the loss of moisture through walls and ceilings. Ft 24 hours or less.

Seal krete vapor shell is designed to reduce moisture vapor emission levels up to 25 lbs 1000 sq. The best vapor barriers for concrete floors and slabs are a new generation of poly made from high quality polyolefin resins that are designed to ensure low permeability high tensile strength and superior puncture resistance compared to regular polyethylene sheeting. Most vaporcoat grades are designed for low mvtr to retard water vapor transmission in order to keep perishables fresh frozen goods intact or sensitive contents in factory condition. Then i take the vapor block squeegee it on and it just disappears into the concrete.

I start by grinding the floor to get a nice tooth surface prep is really important. Seal krete vapor shell is a low viscosity clear one coat 100 solids epoxy membrane forming moisture vapor control system formulated to bond to concrete with relative humidity rh. By sealing the concrete surface moisture concentration and pressure equilibriums would be reached inside the concrete which would stop the flow or movement of moisture although not its presence.
