Bostik’s BEST

BEST  is a one-part, trowel-applied, tacking moisture-cure urethane adhesive. This advanced, scientifically-formulated adhesive does NOT contain water. Once cured, Bostik’s Best is waterproof and is not adversely affected by exposure to moisture or water; its superior properties provide a tough, flexible, tenacious bond to a variety of surfaces. Bostik’s Best’s elastomeric characteristics allow the adhesive to move with the wood as it expands and contracts over the life of the floor.   More Info

Moisture Vapor Protection

Vapor-Lock™ Wood Flooring Urethane Adhesive/Vapor-Retarding Membrane

Vapor-Lock™ is a new and improved one-part, trowel-applied, rapid tacking, very low permeability moisture-cure urethane adhesive and vapor retarding membrane. This scientifically formulated adhesive/membrane does NOT contain water, is virtually odorless, and has 0%-VOC’s.

Vapor-Lock offers a tenacious waterproof bond to a variety or substrates and is not adversely affected by exposure to moisture, water, or alkalinity; it can also create a vapor-retarding membrane designed to reduce moderate amounts of moisture vapor transmission from the subfloor and bridge cracks that can occur in the substrate prior to or after installation (up to 1/8”).   More Info

MVP4 (Moisture Vapor Protection)

Bostik’s MVP4™ is a one-part, trowel-applied, elastomeric, moisture-cure urethane membrane designed to:

1. Reduce Moisture Vapor Transmission from the subfloor
2. Create a Noise Reduction Barrier over the substrate, Peace   Noise Reduction
3. Establish an anti-fracture membrane that can bridge subfloor cracks up to 1/8″ prior to or after installation

MVP4 contains Bostik® Blockade™ Antimicrobial Protection, which inhibits the growth of bacteria, mold, or mildew on the surface of the dried cement; the dried cement resists stains caused by mold.   More Info

Bostik Ultra-Set SingleStep

Bostik’s Ultra-Set® SingleStep™ is a one-part, trowel-applied, tacking moisture-cure urethane adhesive & moisture vapor protection membrane. This scientifically-formulated adhesive and membrane is very tenacious, has very low moisture permeability, and is formulated with patent-pending
Thickness-Control™ Spacer Technology to insure proper membrane thickness between hardwood flooring and the substrate. Bostik’s Ultra-Set SingleStep contains NO WATER, is 0-VOC and contains 1% recycled materials.   More Info

D-250 Moisture Vapor Barrier Coating

A high-performance, rapid-drying, water-based, penetrating epoxy formulated to dramatically reduce moisture vapor transmission  and surface alkalinity from substrates including “freshly-poured” concrete, cement backer board, radiant heat flooring, and cement-based terrazzo prior to the installation of engineered or solid hardwood, carpet; vinyl/VCT, rubber; porcelain, marble, granite or ceramic tile floor covering. Bostik EMC is a low-odor, non-flammable, two-component system.   More Info

D-261 Extreme Moisture Vapor Barrier Coating

D-261™ Extreme Moisture Vapor Barrier Coating is a two-component, high performance, rapid drying, epoxy formulated to dramatically reduce moisture vapor transmission and surface alkalinity from substrates including; “freshly-poured/green concrete”, properly prepared concrete, cement backer board, cement patch/underlayments, radiant heat flooring, and cement-based terrazzo prior to the installation of carpet; vinyl/VCT; engineered or solid hardwood; porcelain, marble, granite, or ceramic tile floor covering. D-261 contains Bostik’s Blockade™ antimicrobial protection and utilizes a breakthrough, silver-based, antimicrobial agent that provides built in protection to inhibit the growth of a broad range of odor causing bacteria, mold and mildew on the surface of the coating’s film. D-261 is uniquely formulated so that it may be applied to fresh “green” concrete as soon as it has achieved “initial set” (when the concrete can be walked on without disturbing the surface). It is pigmented light green for visual indication of coverage and film thickness during the installation process. It is extremely durable and wear resistant.

When properly installed, D-261 is designed to reduce the moisture vapor emission rate of even the most challenging concrete slabs from < 25 pounds per 1,000 ft2 per 24 hours to < 3 lbs. per 1,000 ft2 per 24 hours (per ASTM 1869). This non-flammable, non corrosive, low odor, non-blushing formulation requires no solvent wiping, and has no application window in which floor covering adhesives must be applied to achieve a strong bond. D-261 is formulated to be effective in reducing the surface alkalinity of concrete slabs to pH levels of 9 or lower as recommended by the Carpet and Rug Institute and the Canadian Carpet Institute, making them ideal for bonding with most adhesives.   More Info
