COMMERCIAL SPC angle tap Installation 

GENERAL INFORMATION   

Site Conditions and Installation   

• It is recommended that floor covering installation shall not begin until all other trades are completed.    

• HVAC System: Must be operational, maintaining the following conditions 7 days prior to, during and after installation.    

• Acclimation of material prior to installation is not required; however, the floor covering should be installed in a climate-controlled environment with an ambient temperature range between 55°F - 85°F (13°C-29°C) or average temperature of 70°F (21.1°C).   

• Post installation temperature range allowed is an ambient room temperature between 55°F and 100°F (13°C- 37.7°C).  This allowance is for floating floors only and does not apply to glue-down installations.   

• Avoid exposure to direct sunlight for prolonged periods, doing so may result in discoloration. During peak sunlight hours, the use of drapes or blinds is recommended. Excess temperature due to direct sunlight can result in thermal expansion and UV fading.   

• If cabinets are to be installed on top of the flooring (including islands), that area of material must be fully adhered to the subfloor (including an additional 2’ft beyond the cabinets and islands)   

• To minimize shade variation, mix and install planks from several cartons.   

• Inspect all planks for damage before installing. If you have any concerns about the product fit or finish, call Shaw Information Services at 1-800-471-7429. Claims will not be accepted for flooring that has been cut to size and/or installed.   

• Installation Methods: Floating (on, above or below grade) / Glue Down (on, above or below grade)   

• Required perimeter expansion spacing for Floating or Glue Down installation is as follows:  

          For areas less than 2500 sq ft, use 1/4" gap.  

          For areas larger than 2500 sq ft. use 1/2" gap.   

• NOYE: For corridors or areas subject to rolling loads, a full glue-down installation is required. 

• Crumb rubber underlayments are not an acceptable option for use with resilient floor coverings due to performance issues resulting from chemical incompatibilities.   

• Store cartons of tile or plank products flat and squarely on top of one another. Preferably, locate material in the center of the installation area (i.e. away from vents, direct sunlight, etc.)   

• Do not stack pallet’s 2 high unless utilizing a 1” thick plywood in between pallets.   

SUBSTRATE TESTING   

NOTE: IT MAY NOT BE THE FLOOR COVERING INSTALLER'S RESPONSIBILITY TO CONDUCT THESE TESTS. IT IS, HOWEVER, THE FLOOR COVERING INSTALLER'S RESPONSIBILITY TO MAKE SURE THESE TESTS HAVE BEEN CONDUCTED, AND THAT THE RESULTS ARE ACCEPTABLE PRIOR TO INSTALLING THE FLOOR COVERING. WHEN MOISTURE TESTS ARE CONDUCTED, IT INDICATES THE CONDITIONS ONLY AT THE TIME OF THE TEST.   

Concrete Subfloors   

• Do not install over concrete with a history of high moisture or hydrostatic conditions. Excessive moisture in the subfloor could promote mold, mildew, and other moisture related issues like the trapping of moisture emissions under the flooring, which may contribute to an unhealthy indoor environment. Shaw Industries does not warrant nor is responsible for damage to floor covering due to moisture related issues.   

• It is up to the flooring contractor to determine if a subfloor is not cured. Should the subfloor not be cured, a moisture barrier/mitigator like 6 mil poly should be considered for a successful installation and to prevent the material from being damaged by (moisture) vapor from the subfloor.   

• Additional layer of minimum 6 mil poly film or equal vapor retarder with a perm rating of .1 or less may be used as an additional layer of protection.   

• All substrates to receive moisture sensitive floor covering require proper moisture testing.    

• Moisture testing per ASTM F-1869 CaCl/MVER and ASTM F-2170 In-situ Relative Humidity: Testing must be performed per latest revision. Three tests must be conducted for the first 1000 SF and one additional test per 1000 SF.    

• pH / Alkalinity per ASTM F-3441: 7-10 pH   

• Moisture Testing per ASTM F-1869 CaCl/MVER:  8lbs   

• Moisture Testing per ASTM F-2170 In-situ Relative Humidity: 90%   

• Perform Bond testing to determine compatibility of adhesive to the substrate.   

Wood Subfloors   

• Take readings of the subfloor – minimum of 20 readings per 1000 sq. ft. and average the results. In most regions, a “dry” subfloor that is ready to work on has a moisture content of 12% or less.   

APPROVED SUBSTRATES   

Concrete Subfloors       

NEW AND EXISTING CONCRETE SUBFLOORS SHOULD MEET THE GUIDELINES OF THE LATEST EDITION OF ACI 302 AND ASTM F 710, “STANDARD PRACTICE FOR PREPARING CONCRETE FLOORS TO RECEIVE RESILIENT FLOORING” AVAILABLE FROM THE AMERICAN SOCIETY FOR TESTING AND MATERIALS, 100 BARR HARBOR DRIVE, WEST CONSHOHOCKEN, PA 19428; 610‐832‐9585; HTTP://WWW.ASTM.ORG.    

• Concrete floors shall be flat and smooth within 1/8” in 6 feet or 3/16” in 10 feet.    

• F‐Number System: Overall values of FF 36/FL 20 may be appropriate for floor coverings.     

WARNING:  DO NOT SAND, DRY SWEEP, DRY SCRAPE, DRILL, SAW, BEAD BLAST OR MECHANICALLY CHIP OR PULVERISE EXISTING RESILIENT FLOORING, BACKING, LINING FELT, ASPHALTIC “CUTBACK” ADHESIVES OR OTHER ADHESIVES.    

These products may contain either asbestos fibers and/or crystalline silica.  Avoid creating dust. Inhalation of such dust is a cancer and respiratory tract hazard. Smoking by individuals exposed to asbestos fibers greatly increases the risk of serious bodily harm. Unless positively certain that the 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 Covering Institute (RFCI) publication Recommended Work Practices for Removal of Resilient Floor Coverings for detailed information and instructions on removing all resilient covering structures.  For current information go to www.rfci.com.   

Gypsum & Light Weight Concrete Subfloors    

All recommendations and guarantees as to the suitability and performance of lightweight concrete under resilient flooring are the responsibility of the lightweight concrete manufacturer. The installer of the lightweight product may be required to be authorized or certified by the manufacturer. Correct on-site mixing ratios and properly functioning pumping equipment are critical. To ensure proper mixture, slump testing is recommended.   

• Lightweight aggregate concrete having dry densities greater than 90 lbs. per cubic foot may be acceptable under flooring.    

• Concrete slabs with heavy static and/or dynamic loads should be designed with higher strengths and densities to support such loads.    

• Substrates must be primed with 9050 primer or comparable to reduce porosity and promote the bond of adhesive.    

• Perform Bond testing to determine compatibility of adhesive to the substrate 9050 primer can be utilized to promote adhesion.       

Wood Subfloors   

Wood subfloors must be structurally sound and conform to guidelines of ASTM F 1482 and in compliance with local building codes. 

• Do not apply sheet plastic over wood subfloors.  

• Basements and crawl spaces must be dry. Use of a 6-mil black polyethylene is required to cover 100% of the crawl space earth. Crawl space clearance from ground to underside of joist is to be no less than 18” and perimeter vent spacing should be equal to 1.5% of the total square footage of the crawl space area to provide cross ventilation. Where necessary, local regulations prevail.  

• DO NOT install over sleeper construction subfloors or wood subfloors applied directly over concrete. 

• Pier & Beam Construction: Follow local building codes for subfloor assembly, insulation, and airflow requirements in regions with higher humidity.  

• All other subfloors - Plywood, OSB, particleboard, chipboard, wafer board, etc. must be structurally sound and must be installed following their manufacturer’s recommendations.  

• Resilient flooring is not recommended directly over fire-retardant treated plywood or preservative treated plywood. An additional layer of APA rated 1/4" thick underlayment should be installed.  

• Strip – Plank Wood Flooring: Due to expansion/contraction of individual boards during seasonal changes, a 1/4" (6.3mm) or thicker APA rated underlayment panels must be installed over these types of subfloors.   

• Local building codes may only establish minimum requirements of the flooring system and may not provide adequate rigidity and support for proper installation and performance. If needed, add an additional layer of APA rated underlayment, fasten and secure according to the underlayment manufacturer’s recommendations. 

• Panel Subfloors: Truss/joist spacing will determine the minimum acceptable thickness of the panel subflooring. Refer to local building code for spacing and thickness requirements.   

• For Truss/Joist Spacing of 16” o/c or Less: The industry standard for single panel subflooring is a minimum of 5/8” (19/32”, 15.1 mm) CD Exposure 1 subfloor panels, 4x8 sheets. 

• For Truss/Joist Spacing of More Than 16” up to 19.2” (488 mm) o/c: The standard is nominal ¾” (23/32”, 18.3 mm) T&G CD Exposure 1 plywood subfloor panels (Exposure 1) or nominal ¾” (23/32”, 18.3 mm) OSB Exposure 1 subfloor panels, 4’x8’ sheets, glued and mechanically fastened. 

• For Truss/Joist Systems Spaced Over 19.2” (488 mm) o/c up to a Maximum of 24” (610 mm): Minimum 7/8” T&G CD Exposure 1 plywood subfloor panels (Exposure 1) or minimum 7/8” OSB Exposure 1 subfloor panels, 4’x8’ sheets, glued and mechanically fastened. Alternatively, two layers of subflooring or bracing between the truss/joist in accordance with the truss/joist manufacturer’s recommendations, and local building codes may be required. Note that some truss/joist systems cannot be cross braced while maintaining stability. 

Existing Floor Coverings   

Flooring can be installed over most existing hard-surface floor coverings, provided that the existing floor surface is fully adhered, clean, flat dry structurally sound and free of deflection.   

• Existing sheet vinyl floors should not be heavily cushioned and not exceed more than one layer in thickness. Soft underlayment and soft substrates will compromise the product's locking ability as well as diminish its indentation resistance.   

• Installation is NOT allowed over any type of carpet.   

• Do NOT install over wood floors adhered to concrete.   

• This product can be installed over existing ceramic/porcelain tile products with up to a 1/4-inch-wide grout joint.   If the grout joint width exceeds 1/4 inch, a cementitious patching compound should be used to fill the grout joint to make it smooth with the surface of the tile.   

NOTE: THE RESPONSIBILITY OF DETERMINING IF THE EXISTING FLOORING IS SUITABLE TO BE INSTALLED OVER TOP OF WITH RESILIENT, RESTS SOLELY WITH INSTALLER/FLOORING CONTRACTOR ON SITE. IF THERE IS ANY DOUBT AS TO SUITABILITY, THE EXISTING FLOORING SHOULD BE REMOVED, OR AN ACCEPTABLE UNDERLAYMENT INSTALLED OVER IT. INSTALLATIONS OVER EXISTING RESILIENT MAY BE MORE SUSCEPTIBLE TO INDENTATION.  

Quarry Tile, Terrazzo, Ceramic Tile, Poured Floors (Epoxy, Polymeric, Seamless):    

• Must be totally cured and well bonded to the concrete and free of any residual solvents and petroleum derivatives.    

• Waxes, polishes, grease, grime, and oil must be removed.    

• Show no signs of moisture or alkalinity.    

• Cuts, cracks, gouges, dents, and other irregularities in the existing floor covering must be repaired or replaced.    

• Fill any low spots, holes, chips and seams that may telegraph through the new flooring.    

• Grind any highly polished or irregular/smooth surfaces.    

• Quarry tile or Ceramic tile grout joints and textured surfaces must be filled with an embossing leveler or substrate manufacturer approved material.    

Raised Access Panel Subfloors    

• Raised access panels must be stable, level, flat, free and clean of existing adhesives    

• 24" x 24" panels are recommended.    

• Lippage (variation of height) between panels must not exceed 0.0295” (0.75 mm)    

• Gaps between panels must not exceed 0.039” (1mm)    

• There should be no deflection of the individual panels – Concave less than 0.0295” (0.75 mm)    

• Flatness 1/8” in 10’    

• Stagger the flooring tiles/planks to overlap the access panels    

• Telegraphing of access panel seams may be visible and is not considered a product defect nor warranted by the flooring manufacturer.   

• If needed overlay the panels with a 1⁄4” (6 mm) plywood and properly fasten to the access panels prior to the installation of the floorcovering. Prior to underlayment installation, repair any loose or unstable panels. Use the appropriate installation methods for the product.      

Radiant Heated Floors    

The heating system's components must have a minimum of 1/2" separation from the   flooring 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.  The 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.    

• Electric Radiant Floors: consist of electric cables (or) mats of electrically conductive materials mounted on the subfloor below the floor covering.  Mesh systems are typically embedded in thin-set.  When embedding the system components, use cementitious patching and leveling compounds that meet or exceed Shaw’s maximum moisture level and pH requirements.  Use of gypsum-based patching and/or leveling compounds which contain Portland or high alumina cement and meet or exceed the compressive strength of 3,000 psi are acceptable.   

• Hydronic Radiant Floors: pump heated water from a boiler through tubing laid in a pattern under the flooring. Typically installed in channels under a wooden subfloor (or) imbedded in concrete slabs.     

SUBSTRATE PREPARATION   

Concrete Subfloors: New and existing concrete subfloors should meet the guidelines of the latest edition of ACI 302 and ASTM F710, “Standard Practice for Preparing Concrete Floors to Receive Resilient Flooring” available from the American Society for Testing and Materials, 100 Harbor Drive, West Conshohocken, PA 19428; 610-832-9585: HTTP://WWW.ASTM.ORG.   

Wood Subfloors: Wood subfloors must be structurally sound and conform to guidelines of ASTM F 1482 and in compliance with local building codes . 

• All substrates must be structurally sound, clean, dry, and flat prior to installation. Surfaces must be free of contaminants including, but not limited to: dust, dirt, oil, grease, paint, curing compounds, concrete sealers, adhesive residues, loosely bonded toppings, and any other materials or conditions that may inhibit proper adhesion. 

• Substrate flatness must conform to the following tolerances: 

• Maximum deviation of 1/8 inch over 6 feet (3.2 mm over 1.8 m) 

• Maximum deviation of 3/16 inch over 10 feet (4.8 mm over 3.0 m) 

• Fill depressions or cracks with a cementitious patching / leveling compound that meet or exceed Shaw Industries maximum moisture level and pH requirements. Use of gypsum-based patching and/or leveling compounds which contain Portland or high alumina cement and meet or exceed the compressive strength of 3,000 psi (20684 kPa) are acceptable.  

• Dormant cracks wider than 1/32 inch (0.8 mm) may be repaired using Prepworx CJR400. 

• For cracks and saw cuts exceeding 1 inch (25.4 mm) in depth, the use of Prepworx MRS101 is recommended.  

• Moisture Mitigation: For new or existing concrete substrates exhibiting moisture levels that exceed the limits specified for products and/or adhesives, reference either of the two systems below for mitigation. 

• Totalworx Moisture Control Solution 

• Totalworx Vapor Barrier Solution 

• Trench Moisture Mitigation: For newly poured concrete trenches (e.g., plumbing), apply a two-part epoxy moisture barrier such as PrepWorx MCS310 to prevent moisture-related flooring failures. Ensure substrate preparation aligns with Shaw’s installation standards. 

• Use Prepworx CJR400 at the interface between new and existing concrete. 

• Extend Prepworx MCS310 coverage across the trench and a minimum of 8 inches (203 mm) onto the adjacent slab. 

• Concrete and terrazzo substrates need to be a minimum CSP 3 (maximum CSP 5) by use of shot/bead blasting. 

• Do not install flooring over substrates that have been chemically abated: Chemically treated surfaces may compromise adhesion and affect flooring performance. 

• Curing compounds: (DO NOT USE). If present, they can interfere with the bond of the adhesive to the concrete. Seek assistance from a substrate manufacturer if curing agents are detected.  

• Sweeping Compounds: Green sweeping compounds can be used but must be swept and removed immediately.   

• For dusting / powdering / porous concrete / lightweight concrete prime with a latex primer such as 9050.

ADHESIVE AND APPLICATION   

Adhesives provide variations of shear and peel strength depending on chemistry and application. The use of a proper adhesive is important for installation as the adhesive provides the bond of the flooring to the substrate to restrict movement.   It is important to understand the site conditions and installation in choosing the correct adhesive for the installation.     

Glue Down Installation: SPC products are approved for glue down installation over approved wood and concrete substrates. Follow adhesive label application instructions. Install flooring into semi-wet adhesive to achieve a permanent bond. Maintain 1/4” (6.35 mm) perimeter expansion space. Roll flooring immediately after installation with a 100 lbs. 3‐section roller.        

• Trowel Size: 1/16”x1/16”x1/16” sq. notch   

• Open Time/Flash Time: Open time begins at the time of adhesive application to the period the adhesive is ready to accept flooring.    

• Working Time: Working time begins at the start of installation of flooring until the adhesive is inactive, too dry, or past working time stated by the adhesive guidelines.  

Adhesive	Type	CaCl/MVER Limit	RH Limit	PH Limit	Open Time	Working Time	Trowel Size
4200 Resilient	HS	12lbs	99%	5-12	15-20 minutes	30 minutes	1/16”x1/16”x1/16” sq. notch
2200 Resilient	TPS	10lbs	95%	5-12	15-20 minutes	30 minutes	1/16”x1/16”x1/16” sq. notch

INSTALLATION   

Tools: Tape measure, utility knife, jigsaw, tapping block, rubber mallet/dead blow mallet, pull bar, ¼\" spacers, T-square, safety glasses, broom or vacuum, and (if necessary) tools for subfloor repair.  

Expansion Requirements: 

• For installations performed in temperature environments maintained between 55°F and 85°F (13°C to 29.4°C) or totaling 2,500 sq. ft. or less, provide a minimum 1/4" expansion gap at all vertical surfaces. 

• For installations performed in environments with post install temperatures between 55°F and 100°F (13°C to 37.7°C), or for installations exceeding 2,500 sq. ft., provide a minimum 1/2" expansion gap at all vertical surfaces. 

         

 

Step 1: Gather your tools	Step 2: Make sure your space is: clean, flat, dry and structurally sound.	Step 3: Begin installation working from left to right. Insert spacers at ends and edges where tiles meet wall to maintain ¼” expansion space
Step 4: Lock short end of tile by inserting tongue into groove at an angle and drop in place. Continue to end of first row.	Step 5: Use leftover tile from first row as starter for second row. Minimum 8” stagger between tile end joints.	Step 6: Lock long edge of tile by inserting tongue into groove at an angle and drop in place. Slide tile toward end of previously installed tile until the tongue just touches the groove.
Step 7: Use hammer and tapping block to engage tile and ensure tight fit.	Step 8: Attach a scrap piece to align tiles and bridge gaps between tile.	Step 9: Tap end of tiles with hammer and tapping block to engage ends.
Step 10: Use hammer and pull bar to engage final piece, insert spacers and continue to next row.	Step 11: Use hammer and pull bar to lock tiles on final row.

COMPLETION  

• Protect all exposed edges of the flooring by installing wall molding and/or transition strips. Make sure that no plank will be secured in any way to the subfloor.  

• For wet areas such as bathrooms caulk the perimeter of the floor with a flexible silicone caulk.  

• Protect the finished flooring from exposure to direct sunlight to reduce fading and thermal expansion.  

• Cutting resilient product into a fine point may lead to delamination. Use an ethyl cyanoacrylate based glue to help fuse the resilient point together. Be sure to clean all glue from the top surface immediately. Alcohol based glues may cause resilient products to swell.  

• Adhering tape to the surface of your resilient flooring could damage the surface.   
  Do not use tape to secure floor protection directly to the floor during construction or renovation. Instead, adhere tape to the material used to protect the floor and secure it to the base molding along the wall.  A material such as ram board can also be used to protect your flooring.
