Hush IINoise Reduction Underlayment

071VS

Installation InstructionsThe following installation instructions are a recommendation and are not intended as a definitive project specification. They are presented in an attempt to be used with recommended installation procedures as published by the Resilient Flooring Industry. For use with Resilient Plank and Tile only, NOT for use with resilient sheet goods.

Site ConditionsThe installation site must be acclimated, with the HVAC system in operation. The floor and room temperature, as well as the Hush II underlayment, flooring materials and adhesives must be maintained at 65–85˚ F and the relative humidity below 60% for 48 hours prior to, during and after the installation.

Subfloor

1. All substrates shall be smooth, structurally sound, permanently dry, cleanand free of all foreign material such as dust, wax, solvents, paint, grease,oils, old adhesive residue, curing and hardening compounds, sealers andother foreign material that might prevent adhesive bond.

2. Concrete subfloors shall be flat and smooth within 1/8" in 6 feet or3/16" in 10 feet.

3. Wood subfloors need to be structurally sound and in compliance withlocal building codes.

4. Inspect concrete subfloors for any open cracks and fill with a high-gradeepoxy filler or polymer modified cementitious floor patch.

5. Lightweight concrete or gypsum based subfloors must be free of structuralcracks and prior to the application of an adhered underlayment or finishfloor, must be primed with two coats of the SHAW 9050. If theunderlayment is loose laid, priming is not required.

6. Remove any excess lumps or residue from the subfloor that may interferewith the installation of the SHAW Hush II underlayment or would possibly“telegraph” through the finished flooring.

Testing for Moisture – Concreteo Calcium Chloride test method per ASTM F 1869 or In-Situ Relative

Humidity test method – ASTM F 2170 test must be performed.o Lightweight concrete: Internal Relative Humidity – Tests should be

performed per the latest edition of ASTM F 2170. Three internal relativehumidity tests should be conducted for areas up to 1000 sf.

Perimeter Isolation

It is important that the finished flooring not directly contact the perimeter walls or vertical partitions of the entire floor area, including any openings or protrusions such as electrical boxes, heating ducts, cold air returns, columns or pipes in the subfloor installation.

Perimeter Isolation can be achieved by leaving at least a ¼" expansion gap between finished flooring and the fixed partitions or walls.

Adhesives

SHAW 200 TPS: 1/16" x 1/16" x 1/16" square notch trowel is required. Maximum moisture vapor emissions must not exceed 5 lbs/1000 sf per 24 hrs using the Calcium Chloride ASTM F 1869 or 85% rh using the In-Situ Relative Humidity ASTM F 2170 and a ph level between 5–9.

SHAW S150: Spray adhesive: Spread rate is approximately 100–150 sq ft per can depending on the substrate. Moisture vapor emissions must not exceed 90% using the In-Situ Relative Humidity ASTM F 2170 test and a maximum ph level of 10.

SHAW 4100: 1/16" x 1/32" x 1/32" U-notch trowel. Moisture vapor emissions must not exceeed 90% using the In-Situ Relative Humidity ASTM F 2170 test and a maximum pH level of 10.

Installation for Glued Down Luxury Vinyl Plank and Tile ONLY (Double-Glue)1. Cut the SHAW Hush II roll material to the desired length and position

the material in the space to be covered.

2. Proceed to cover the entire room, making sure the sheets are tightly buttedtogether, without gaps. Open seams and gaps will “telegraph” throughmost vinyl, so the underlayment work must be as smooth and well seamedas possible.

3. Never mechanically fasten the sheets to the subfloor, as this will severelydiminish the acoustical value of the product.

4. Pull the loose laid material back at least half the length of the cut materialand apply an approved adhesive to the substrate.

5. SHAW 200 TPS: Use a 1/16" x 1/16" x 1/16" square notch trowel andallow adhesive to flash off 10–20 minutes. Note: For lightweight concreteprimed with Shaw 9050, or other limited porosity substrates, use a1/16" x 1/32" x 5/64" U-notch trowel, making sure to completelycover the substrate. Allow a 30–40 minute flash time and install theHush II underlayment while the adhesive is partially but not completely dry.

6. When using SHAW S150 spray adhesive, spray an even amount ofadhesive on the subfloor (approximately 100 sq ft per can) and allow theadhesive to dry to the touch before installing the Hush II underlayment.

7. SHAW 4100: Use a 1/16" x 1/32" x 1/32" U-notch troweland allow adhesive to flash off 10 minutes.

8. Install the underlayment and, upon completion, roll the material with aroller (75 lbs or less) to insure contact with the adhesive.

9. Hush II underlayment should cover the entire floor area without gaps andbe securely bonded with the joints tightly butted.

10. Allow underlayment to cure for a minimum of 3–4 hours.

11. After 3–4 hours you can then proceed to install the luxury vinyl tileor plank following resilient installation guidelines for a non-poroussubstrate (adhesive in pressure sensative mode).

Installation for Floating Resilient Floors (Residential application only) Commercial products – underlayment must be full spread prior to floating vinyl products.

1. If the underlayment is to be loose laid, the seams should be securely tapedand it may also be advisable to bond it to the subfloor at the perimeter,doorways and/or areas that transition into other flooring materials, usingeither an adhesive or commercial grade double faced tape.

2. Cut the SHAW Hush II roll material to the desired length and position thematerial in the space to be covered. Proceed to cover the entire room,making sure the sheets are tightly butted together, without gaps. Openseams and gaps will “telegraph” through many resilient flooring products,so the underlayment work must be as smooth and well seamed as possible.

3. Once the underlayment is installed on the subfloor, care should be exercisedto avoid having it move or shift during the installation of the finished flooring.Follow resilient installation instructions for installing the finished flooring product.

4. If a rigid baseboard or shoe molding detail is required, leave a minimum1/8" gap between the finished floor and the bottom of the quarter roundor baseboard molding. This gap can be filled with a non-hardening, colormatching, paintable or clear Acoustical Grade Sealant.

• Commercial and residential sheet vinyl flooring • Rubber flooring • Resilient sports flooring • Wood court flooring • Installations Guidelines

SLAB RH TESTING AND PRE-INSTALLATION REQUIREMENTS

All concrete slabs, regardless of grade, should be tested for moisture content using the approved method of RH in-situ probe testing in accordance to the latest version of ASTM F-2170. Slabs should only be tested 28 days after pour and once the slab has been allowed to realize appropriate service conditions, which includes permanent heat/HVAC operations and complete enclosure of the space.

Acclimate all flooring materials and adhesives in accordance with the flooring manufacturer’s recommendation. Floors and the planned installation space should be conditioned at least 48-72 hours prior to the start of the installation. Environmental conditions should remain constant during the installation and after the installation is completed. Permanent HVAC should be in operation and set to between 65°F - 85°F.

Always inspect KOVARA™ MBX, KOVARA™ tapes, and flooring materials for physical damage and/or defects. The installation of defective or damaged materials, in most cases, may deny any future rights to a claim.

KOVARA™ MBX installations, including floor preparation and finished flooring, should not be started or installed where further trade work on or above the product will be required. Always read the associated documentation and installation instructions for all flooring, adhesives and underlayment to be installed.

When selecting adhesives, KOVARA™ MBX is considered a non-porous surface. The appropriate adhesive, recommended trowel size and/or spread rate should be specified by the flooring manufacturer. If considering adhesives classified for wet-set applications, contact GCP Technical Services for specific application recommendations.

CONCRETE SUBSTRATE PREPARATION

All of the recommended work practices contained in these guidelines are in conformance with the most recent version of ASTM-710 and acceptable industry guidelines as approved by RFCI. The installation contractor is solely responsible for determining the suitability of a slab, moisture testing and use prior to starting the installation of KOVARA™ MBX.

The concrete slab should be smooth, dry, clean and structurally sound. Dust and other contaminants may have an effect on the mechanical bond of the KOVARA™ tapes to the substrate and overall performance of the system.



All surface cracks, grooves, depressions, control or other non-moving joints greater than 1/8” should be filled and sanded smooth with the plane of the substrate using modified Portland cement patching compounds or an epoxy injection. Crowns in slab or protrusions should be smoothed in the same manner. Patching materials should be allowed to completely dry prior to the application of KOVARA™ MBX and finished flooring materials.

Existing adhesives should be completely removed to provide a tack-free substrate. Please follow the RFCI’s (Resilient Floor Covering Institute) “Recommended Work Practices for Removal of Existing Floor Covering and Adhesive.”

Substrates that have been installed with cutback adhesives should only be removed in strict accordance with local, state and federal guidelines. If the slab has been abated using a chemical process, immediately contact GCP Technical Services for additional encapsulation and installation recommendations.

Do not use gypsum- or plaster-based patching compounds underneath KOVARA™ MBX. Areas requiring deep fill, other than a skim coat, should only be repaired using a MRP (moisture resistant patch) or exterior grade patching/repair compound. Consult your manufacturer for additional recommendations on these types of substrate repair products.

INSTALLATION OVER EXISTING RESILIENT FLOORING

Ensure the existing floor is well bonded and securely attached. Such installations should not exceed one layer of non-cushioned resilient flooring beneath KOVARA™ MBX.

The existing floor must show no indication of failure related to moisture or alkalinity. Tiles that have de-bonded, cracked or cupped should be removed and replaced with new flooring tile or filled with an approved patching compound to smoothly transfer to the surrounding flooring materials.

Floors with embossed surfaces or textures should be made smooth using an approved latex embossing leveler or modified Portland cement patching compound approved for this process.

All waxes and/or sealers should be removed using industry approved methods prior to the installation of KOVARA™ tapes and encapsulation KOVARA™ MBX.

KOVARA™ MBX INSTALLATION

Apply KOVARA™ 4” double-sided tape at all doorways and transitions to other flooring materials to prevent air from entering below the system or movement of the KOVARA™ MBX. If the floor to be installed will be heavily trafficked or used with heavy rolling loads, please refer to the Box Grid Application Method on gcpat.com before continuing.

Evaluate the KOVARA™ MBX seam layout by measuring across the room and laying chalk lines to clearly identify the seam line locations. These lines will serve as a guide for setting the required 4” double-sided tape correctly. Begin by setting the first chalk line 4’10” away from one wall, and then measure all subsequent lines at 5’ intervals away from the first chalk line. Continue this pattern across the entire room

When installing around floor monuments, columns, or poles, splice the KOVARA™ MBX to fit around the obstructions and tape to secure the seams in this area.



Begin placing the tape by anchoring the double-side tape along the first chalked line. The edge of the tape closest to the first wall should sit right along the chalk line. Pull the tape across the entire length of the seam line. Set the KOVARA™ Double Sided Tape in place and roll the KOVARA™ Double Sided Tape, ensuring that you have removed any wrinkles and the tape is flat. DO NOT REMOVE THE RELEASE FILM FROM THE KOVARA™ DOUBLE-SIDED TAPE AT THIS TIME. Continue the process by placing tape at each of the newly snapped chalk lines, with the edge of the tape closest to the first wall sitting along the chalk line.

Unroll the KOVARA™ MBX material starting at a wall, ensuring that the first piece falls exactly centered across the installed KOVARA™ double-sided tape. The smooth, glossy side of the KOVARA™ MBX should be facing the substrate (down) and the rough, textured side should be facing up. Net fit to walls and trim to fit. Individual cuts should not exceed 30 linear feet in length.

Repeat the previous step to complete the layout of subsequent pieces, ensuring that the end cuts are staggered to allow the offset of cross seams.

Working from one side of the room, lightly butt the first two adjacent pieces of KOVARA™ MBX together ensuring that both sheets fall centered over the previously placed KOVARA™ double-sided tape. Continue by removing the release film through the seam, while at the same time setting the KOVARA™ MBX membrane into the tape. Continue this process across the entire installation, and roll all seams with either a hand roller or 75-100 pound resilient roller. NEVER OVERLAP SEAMS as it may telegraph through the finished flooring, and NEVER USE COMPRESSION METHOD at any seams.

Complete the installation by setting the blue KOVARA™ MBX seam tape across the top of all side seams and cross seams. Maintain adequate tension on the tape when setting to minimize bubbling and wrinkling. Roll the seam with the approved roller.

FINISHED FLOORING INSTALLATION

Sweep the KOVARA™ MBX membrane to remove any installation debris, dust or dirt that may have accumulated during the application. Complete the finished flooring installation in accordance with all manufacturer guidelines. Apply the adhesive directly to the surface of the KOVARA™ MBX in accordance with the manufacturer’s recommendation for non-porous substrates.

With the continuous advancement of flooring technologies, it is impossible to list all of the products that can be effectively installed using KOVARA™ MBX. If your product is not included in the list of approved floor coverings, please contact GCP Technical Services for additional information. Always follow your specific flooring manufacturer’s recommendations for installation over non-porous substrates.

Perform necessary planning and layout of all flooring materials. We recommend lighter chalks as they will be clearly seen on the surface of the KOVARA™ MBX. Always adjust the layout to avoid seam joints falling directly over a KOVARA™ MBX seam.

Caution should be taken to ensure the KOVARA™ MBX membrane is not cut, damaged or punctured. Some adhesives may take longer to flash off and cure compared to installations over porous concrete. Always use a new trowel with the recommended notch for each application.

.



Do not mechanically fasten wood flooring through KOVARA™ MBX. Regarding floating flooring systems, carefully follow all flooring manufacturer’s recommendations for the installation.

INITIAL MAINTENANCE

Upon completion of the finished flooring installation, KOVARA™ MBX requires a minimum of 120 hours (5 days) before conducting initial ‘wet’ cleaning or maintenance. Failure to follow this requirement may result in improper adhesive curing and/or failure of the adhesive bond. Always clean and maintain flooring with neutral pH cleaning products.
