Installation Instructions VersaShield MBX is a rolled moisture barrier designed to reduce the upward movement of water vapor from concrete floor slabs into finished flooring systems. VersaShield MBX can be installed in elevated slabs (structural concrete, precast, or slabs on metal decks) and on slaps on-ground (on-grade and below-grade). Moisture Test Testing must be conducted prior to initial VersaShield MBX installation with results documented and retained in order to be in compliance with the VersaShield MBX Limited Warranty. Testing must be conducted in accordance with the latest version of ASTM F2170; a maximum reading of 99% RH is allowed. Do not install VersaShield MBX on slabs below-grade where hydrostatic pressure exists. Preparation of Concrete Subfloor All joints, cracks, and variations in the concrete surface 1/8" or greater must be filled. Use a quality patching and/or leveling compound warranted by the compound manufacturer to withstand high moisture conditions. Protrusions must be ground flat. All patching, leveling, and/or crack suppression materials must be cured and surfaced dry before installing VersaShield MBX. Concrete slab surface must be dry, smooth, clean, flat, and structurally sound within flooring manufacturer's specifications. Residual adhesives must be scraped down to the concrete surface and removed prior to installation of VersaShield MBX ensuring a no-track surface is obtained. If the scraped surface has residual tackiness of old adhesive, a flat trowel application of a cementitious skim coat is required.. VersaShield is warrantied for installations over abated floors. Abated floors require a water and mild neutral detergent rinse of the surface. After the water and mild neutral detergent rinse is performed, rinse the surface with clean water and allow the surface to dry. VersaShield may then be installed according to normal installation standards. If contaminants are known or suspected, contact Halex Corporation Technical Services at 800-576-1636 for more information. STEP 1: Installation of VersaShield 4" Wide VSDS Double-Sided Tape Store VersaShield 4" Seam Tape indoors in a cool, dry area at temperatures between 60 F and 80 F. VersaShield 4" Wide VSDS double-sided tape is marked with the VersaShiel MBX logo on the tape core for identification; use of any other seam tape is neve recommended and will void the VersaShield MBX Limited Warranty. Determine the required layout of the VersaShield MBX Rolled Moisture Barrier. Utilize a chalk line or straight edge line, mark the floor where the VersaShield MBX Rolled Moisture Barrier will be positioned. Apply the VersaShield double-sided tape directly (centered) over the seam lines marked on the floor. Use a hand roller to roll the tape, as it will ensure the VersaShield MBX doublesided tape properly adheres to the concrete surface. Do not remove the top release paper from the upper side of the VersaShield double-sided tape at this time. STEP 2: Installation of VersaShield MBX Rolled Moisture Barrier The rolls of VersaShield MBX should be acclimated for a minimum of 24 hours at the job location. Roll out the VersaShield MBX moisture barrier in desired placements starting in one corner of the room. Install the shiny, light blue underside down and the rough, mineral-coated dark blue surface facing up. Roll out VersaShield MBX positioned 1/8" from wall. When installing VersaShield, cut and tape cross seams at 25 and 30 feet creating a random stagger. VersaShield MBX cuts easily with scissors or utility knife. Roll out additional VersaShield MBX rolls, tightly butting the side edges to one another. Do not overlap seams and ensure no gaps. The seam should be centered over the midpoint of the 4" wide VersaShield doublesided tape. The top facing release paper can now be removed from the VersaShield doublesided tape at the desired start point, without altering the position of the VersaShield MBX above it. Adhere the first 3 feet of the VersaShield MBX to the top of the exposed VersaShield double-sided tape using a hand roller. After achieving good adhesion, proceed to remove the remaining release paper and continue to hand-roll the remainder of the seam. Make sure the seams remain butted and flush with no overlapping.
STEP 3: Installation of VersaShield MBX 2-1/2" Wide Seam Tape The top of the seam must now be secured. Tape all seams with VersaShield MBX 2-1/2" wide seam tape and roll with a hand roller to insure a good bond. VersaShield MBX is easily cut to fit around irregular objects such as pillars and poles; use VersaShield MBX 2-1/2" wide seam tape to secure the seams in these areas. Store VersaShield MBX 2-1/2" wide seam tape indoors in a cool, dry area at temperatures between 60 F and 80 F. VersaShield MBX 2-1/2" wide seam tape is marked with the VersaShield MBX logo on the tape and tape core for identification purposes; use of any other seam tape is never recommended and will void the VersaShield MBX Limited Warranty. VersaShield VSM-DS double-sided 4" tape (white) must be used for utility purposes at door threshold plates, around walk off mats, floor boxes, pillars and non-flat flooring surfaces. Concrete must be smooth, clean, and free of debris, oily materials, coatings, and other surface treatments. Unroll VersaShield double-sided tape with release liner attached, cut at desired length, apply to the concrete surface, firmly press on the release liner using a hand roller, peel off the release liner section by section as the VersaShield MBX Rolled Moisture Barrier is ready to be applied. Firmly press on VersaShield MBX using a hand roller or 100 pound roller. STEP 4: Installation of Flooring Install floor covering on top of VersaShield MBX mineralcoated (rough) surface in accordance with the flooring manufacturer's written instructions. Acclimate the floor covering at the installation site per the flooring manufacturer's requirements. The floor covering manufacturer's recommended installation guidelines must be followed using recommended adhesives and application guidelines. Apply the floor covering manufacturer's recommended adhesive directly onto the VersaShield MBX blue mineralcoated surface. Take care not to scratch, rip, tear, puncture, or damage the VersaShield MBX while spreading adhesive. VersaShield MBX's surface is non-porous; adhesives will take longer to flash off. If the flooring manufacturer has specific recommendations regarding adhesive and trowel size for different types of concrete, VersaShield MBX rolled moisture barrier should be considered non-porous. When installing LVT, VCT, or SVT, ensure the seams of VersaShield MBX are offset from the seams of the LVT, VCT, or SVT. Vinyl plank type tile should be installed perpendicular (90 degrees) to the VersaShield MBX seam pattern. When installing carpet tiles, the carpet tiles should be adhered directly to the VersaShield MBX. Ensure the seams of the VersaShield MBX are offset from the seams of the carpet. Most wide width carpets may be installed over VersaShield MBX. Some pattern match carpets may require stay nailing, knee kicking, crab stretching, or power stretching. These applications are not approved, as they may act to damage or distort the VersaShield MBX. VersaShield MBX is not approved for use with unitary backed carpets. When installing laminates and engineered wood flooring, planks should be installed perpendicular (90 degrees) to the VersaShield MBX seam pattern. Ensure the seams of the VersaShield MBX are offset from the seams of the laminate and engineered wood flooring. Floating (non-adhered) floor covering is installed according to the manufacturer's instructions. VersaShield MBX is not recommended for use with mechanically fastened floor coverings. There are many variations of each type of floor covering. Always check with the flooring adhesive manufacturer for approved product use, application instructions, and best practices. STEP 5: Cleaning and Maintenance Upon completion of the finished flooring installation, Halex Corporation requires a minimum of 5 days (120 hours) prior to conducting initial cleaning or maintenance. Failure to follow this requirement may result in improper drying and interruption of the normal curing process of the adhesive. After waiting the prescribed time period, accepted cleaning and maintenance procedures may begin. 02/16
