Moisture no more
This premium product is best used prior to the application of hardwood flooring, carpet and tile. Controlling moisture vapor emission rates of up to 20lb / 24 hr / 1,000 ft, a waterproof floor is in your future
Standard packages are in pre-measured kits and should be mixed as supplied in the kit. We highly recommend that the kits not be broken down unless suitable weighing equipment is available. Mix each individual component before using. Mix part A and part B together with slow speed mixing equipment such as a jiffy mixer until the material is thoroughly mixed and streak free. Avoid whipping air into the liquids. After mixing, transfer the mixed material to another pail (the transfer pail) and again remix before applying to the concrete substrate. Improper mixing may result in product failure.
The mixed material can be applied by brush or roller. However, the material can also be applied by a suitable serrated squeegee and then back rolled as long as the appropriate thickness recommendations are maintained. When applying by serrated squeegee, back roll the material at a right angle to the direction of the squeegee application. Maintain temperatures and relative humidity within the recommended ranges during the application and curing process. Do not use any heating equipment that would produce carbon dioxide. When rolling out the product, it is best to roll out the product in one direction and then back roll the material in the opposite direction to make sure it is worked into the concrete well. If concrete conditions or over aggressive mixing causes air entrapment, then an air release roller tool should be used prior to the coating tacking off to remove the air entrapped in the coating. When the mixed material is applied to the concrete surface, pin holes or voids may develop when air is displaced (outgassing). If voids or pin holes occur, re-application to remove them must be undertaken. Grind these areas and clean off residue; make sure the surface is dry and re-coat. Thinner applications than recommended may result in insufficient moisture vapor protection.
Concrete treated with Vapor-Tek 440 can be covered with wood flooring, tile, carpet or an epoxy floor system. For proper adhesion, use a product or primer suitable for application over a non-porous surface when applying to the moisture vapor product. Wait at least 12-16 hours before applying flooring, coatings, overlays, or other surfacing before the material is properly set up. Cooler temperatures or a colder substrate might need additional curing time. Usually, the degree of cure is sufficient when you can firmly press down on the coating with your thumb and leave no marking. The maximum recoat window for the Vapor-Tek 440 is 48 hours.
Clean equipment, tools and surfaces with xylol. Unused or old material may be disposed of in a waste disposal site in accordance with local, state and federal laws.
Use appropriate safety equipment during application and handling. Please refer to the safety data sheet (SDS) for additional precautionary instructions before use.
100 square feet per gallon. Variations in texture and porosity of substrate will affect the coverage and performance of the product.
