Dry-Back Glue Down Installation Instructions

General Information 

SAR Floors flexible glue-down flooring products must maintain proper temperature before, during and after installation to help minimize dimensional changes. All flooring material, subfloor and the adhesive must be left at a constant temperature of between 65 degrees F (18 degrees C) and 85 degrees F (29 degrees C) for 48 hours prior to, during and 48 hours after installation. After the installation period, the room temperature must remain between 55 degrees F (13 degrees C) and 95 degrees F (35 degrees C).

DO NOT MECHANICALLY CHIP OR PULVERIZE EXISTING RESILIENT FLOORING, BACKING, LINING FELT, AS-PHALTIC “CUTBACK” ADHESIVES OR OTHER ADHESIVES. Installed resilient floor covering products and the asphaltic or cutback adhesives used to adhere them may contain either asbestos fibers and/or crystal- line silica. The products in this carton do not contain asbestos or crystalline silica. Avoid creating dust or inhalation of asbestos/crystalline dust as they can cause cancer and respiratory tract hazard. Smoking by individuals exposed to asbestos fibers greatly increases the risk of serious bodily harm. Unless positive- ly certain that the previously installed product is a non-asbestos containing material, you must presume it contains asbestos. Regulations may require that the material be tested to determine asbestos content and may govern the removal and disposal of material. See current edition of the Resilient Floor Cover- ing Institute (www.RFCI.com publication “Recommended Work Practices for Removal of Resilient Floor Coverings” for detailed information and instructions on removing all resilient covering structures.
General Information 

All subfloor surfaces must be clean, dry, flat, free of movement and smooth. All surface imperfections should be filled and sanded with a Portland cement-based latex patching compound. Flat within 3/16” in a 10’ radius and or 1/8” in a 6’ radius. Sand high areas or joints. Fill low areas with a high compressive strength Portland base compound.

Remove all residual adhesive with an approved method on previously covered concrete floors. Never use solvent-based adhesive removers.

Dry – Select the appropriate moisture indicator test specifically designed for use with wood or concrete subfloors. Test and record moisture content results. Do not install flooring if moisture test results exceed recommended limits. (www.RFCI.com)
Concrete Subfloors
  1. Concrete subfloors must be smooth, dry and free from dust, paint, grease, solvent, asphalt sealing com- pounds, oil and other materials. The surface must be dense and hard and free from flaking or powder.
  2. New concrete slabs must be thoroughly dry and completely cured. The process takes a minimum of 6 weeks.
  3. Surface hardeners, curing agents and other additives may cause adhesive bonding failure. These should be removed by sanding or grinding.
  4. Moisture arising from new or old concrete can create high levels of alkalinity, hydrostatic pressure and moisture vapor emissions. This combination is highly damaging to the floor and will cause long term, damaging affects. To avoid this problem, ensure that concrete subfloors are constructed according to the American Concrete Institution’s guidelines (ACI’s 302.2 Guide). To check current conditions, a calcium chloride test (ASTM F1869) and a RH test using in situ Probes (ASTM F2170) is necessary. If the level of vapor emissions / hydrostatic pressure exceeds 6 lbs and /or 90% RH, a moisture barrier must be installed over the concrete.
Wood Subfloors
NOTE: Modification of existing structural components may be required for a successful installation.
  1. Screw or nail any areas that squeak or are loose. Wood panels should exhibit an adequate fastening pattern. They should be screwed, nailed or glued as that system requires, using an acceptable pattern. Flatten edge swell as necessary and replace any swollen. water-damaged, or delaminated underlayment or subflooring.

  2. Wood subfloor panels should be a minimum of 1” or thicker and free of vertical deflection. All fasteners must be flush with the subfloor panels.

  3. Basements and crawl spaces must be dry. The crawl space clearance from ground to underside of joist should be no less than 18” and perimeter vent spacing should be equal to 1.5 percent of the total square foot- age of the crawl space area to provide cross ventilation. Use of a 6 mil black polyethylene membrane is required to cover 100% of the crawl space earth.

Finished Flooring Installation

Spread the SAR 5000 adhesive over one half of the floor up to the center line. Allow the adhesive to dry to tack before installing the plank (see SAR 5000 adhesive pail label for clarification). Allow the adhesive to dry completely to tack prior to flooring installation.

Start installing plank along the center line. Complete each row (including cut pieces at the wall) before proceeding to the next row. Offset end joints by at least 6 inches and position planks in at random, working out of three to four cartons for the best appearance. Position each plank lightly against the previous one by pressing it firmly into place without sliding it. Remember to avoid small cuts of less than 6 inches at the ends of each row and place the cut ends towards the wall.

If it is necessary to adjust or remove a plank, use a heat gun to first warm the plank. Complete the opposite side of the room in the same fashion as the previous side.
Cutting a plank to fit

The last row of planks will need to be cut to fit to walls and other vertical surfaces.

Straight Cuts: Place loose plank directly over the top of the last full installed plank. Line up all of the edges. Using a plank to measure the distance from the wall to the last installed plank, position the edge against the wall and mark the loose plank with a pencil where it meets the installed plank at the opposite edge from the wall. Next, place the marked plank on a cutting board. Using a carpenter square to guide, score the pencil line carefully with a sharp knife, then break/snap/cut the plank along the score mark. Install plank with the cut edge toward the wall.

Irregular cuts: Scribe plank to fit irregular shapes such as pipes and door trims, pipes , etc. Cut with a utility knife.

Immediately after installation

Roll the entire floor with a 100-pound roller with 3 sections. Restrict foot traffic for the first 24 hours after installation. Replace the base moldings and return furniture and appliances to the room gently over hardboard strips.

Seal all areas that may be exposed to surface spills (i.e. toilets, showers, tubs, etc. with silicone caulking.
Plank Repairs
  • Warm plank with a heat gun

  • Using a sharp utility knife, cut corner of damaged plank. Do not cut subfloor below.

  • Lift the end of plank and continue heating

  • When enough heat is provided the plank will release from the adhesive

  • Lift up entire plank and warm the exposed adhesive and install new plank

  • Set new plank firmly into place with hand roller

Warnings & Tips:
  • Use soft bristle broom to sweep regularly.
  • For heavy pieces of furniture, use felt protectors under legs.
  • All exterior entrances should have protective Do not use mats made of PVC or rubber or PVC but instead urethane backed mats. Mats should be cleaned regularly to avoid becoming a soil source.
  • Spiked heels or shoes in need of repair can severely damage your floor.
  • Replace hard plastic or metal furniture casters/wheels with soft rubber casters.
  • Prolonged, direct exposure to sunlight can change the color of planks.
  • Never slide or roll heavy furniture or appliances across the floor.
  • Keep animal nails trimmed.

Radiant Heat:

SPC / LVP Over Radiant Heat:

Radiant Heating: Radiant-heated subfloor systems can be concrete, wood or a
combination of both.

The heating systems components must have a minimum of 1/2″ separation from the heating system to the flooring covering product. The system must be on and operational for at least 2 weeks prior to installation to reduce residual moisture. Three days prior to installation lower the temperature to 65 degrees. After installation, gradually increase the temperature in increments of 5° F to avoid overheating. Maximum operating temperature should never exceed 85°F. Use of an in-floor temperature sensor is recommended to avoid overheating. Contact the manufacturer of your radiant heating system for further recommendations.

Warning: Heating mats work very well under carpet, tile, and stone. However, we do not recommend having them placed directly underneath the Vinyl SPC or LVP floor. It is best to install Vinyl SPC flooring over hydro-based radiant heating systems.

LVP (dry-back, glue down) specific:

Use only recommended flooring adhesive over manufacturer’s recommended plywood substrate. The system must be on and operational for at least 2 weeks prior to installation to reduce residual moisture. Turn the heat off for 24 hours before and during installation, and 24 hours after installation when installing over radiant heated subfloors. Failure to turn the heat off may result in shortened working time of the adhesive.

Floor temperature must never exceed 85°F (30°C).

Failure to strictly follow adhesive manufacturer’s guidelines may result in failure and void warranty.
