Concrete Vapor Barrier Coating

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.

Concrete vapor barrier coating.

Ft 24 hours to 3 lbs 1000 sq. 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.

Ft 24 hours or less. Seal krete vapor shell is designed to reduce moisture vapor emission levels up to 25 lbs 1000 sq. It has 0 voc s as calculated per scaqmd rule 1168 low odor and is solvent free. 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.

It really gets into the concrete and takes a bite. From crown polymers he purchased some crowncote vapor barrier an ultra low viscosity epoxy. It s hard to beat epoxy concrete floor coatings for their durability and abrasion resistance making them ideal for high traffic commercial applications. It combines a primer and finish in a single fast drying coat and is specially formulated for manufactured housing facilities.

Vaporcoat recyclable water based coatings confer high barrier to paper based packaging and wraps. 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. This approach offers a simple roll on impermeable barrier on the inside surface of the concrete. Moisture vapor barrier primer finish interior latex is a coating designed to reduce the loss of moisture through walls and ceilings.

However a big drawback of most epoxies is that they don t breathe and will trap moisture vapor coming up from the concrete slab. Slab cote passes astm f 3010 13 moisture mitigation system for use under resilient flooring. 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.
