Surface Preparation

Bostik UltraFinish™ is a fast-setting, latex-fortified, Portland cement-based patch for interior use prior to the installation of hardwood, ceramic, carpet, vinyl, or rubber flooring. This product may be used to skim coat or feather-edge up to 1" deep in one application. Floor covering can be installed typically in as little as 15-20 minutes over concrete, wood, ceramic and quarry tile without the requirement of priming or the use of a liquid additive. When mixed with Durabond D-L16™ High Strength Additive or Bostik's Hydroment 425 Multi-Purpose Acrylic Latex Admixture instead of water, Bostik UltraFinish can be used as an embossing leveler.
This product contains Bostik's 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.

SL-150™ is a high compressive strength, self-leveling, cement-based underlayment. It is used to repair, smooth and level concrete as well as existing ceramic, terrazzo or approved plywood sub-floors prior to the installation of carpet, vinyl, VCT, laminate, solid and engineered hardwood flooring installation, ceramic or natural stone. Suitable for thicknesses from feather-edge to 1” thick, or up to 5” thick when mixed as designed with pea gravel. Use on, above, or below grade. Use SL-150 in smaller installations where it may be mixed by hand, or use underlayment pump to quickly cover large jobs.

Fast Patch 102 is a fast-setting, polymer-modified, cement-based compound. Simply mix with water to repair cracks, holes and uneven surfaces from feather-edge up to 1/2" thick in a single application. Use Fast Patch 102 prior to installation of carpet, wood, ceramic tile and stone floors. It can be applied over concrete, existing ceramic tile, exterior-grade plywood and well-bonded vinyl tile.
, 

When Hydroment 425 Multi-Purpose Acrylic Latex Admixture™ is mixed into Fast Patch 102 cement-based patch instead of water, not only is the performance and flexibility improved, but Fast Patch102 can also be used as an embossing leveler.
Available in 5 gallon, 2 gallon, 1 gallon, and quart containers.

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”).

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.
