R E V . 1 1 - 8 - 1 0 INSTALLATION, SUBFLOOR AND UNDERLAYMENT REQUIREMENTS Approved subfloors: a. b. c. Concrete: The concrete must be free of any curing compounds or adhesives. Even after old glued down carpet has been removed, and the subfloor has been scraped, it should NOT be assumed that the concrete is porous. Often the old adhesive has sealed the floor. A porosity test, using water, should be taken. Be aware that porous subfloors may take a different adhesive than non-porous subfloors.
R E V . 1 1 - 8 - 1 0 g. installation and remain off for at least 6 days after installation to allow the adhesive to fully cure. Maximum operating temperature should never exceed 85°F. Radiant heat components must be a minimum of ½” separated from adhesive and tile. Quarry tile, terrazzo, and ceramic tile: Properly cleanse substrate using a commercial degreasing/dewaxing solution. Grind any highly polished or irregular surfaces.
R E V . 1 1 - 8 - 1 0 SUBFLOOR PREPARATION In general, all substrates must be free of contaminants such as dirt, weak concrete, grease, wax, oil, sealers, paints, curing compounds, and old adhesives. The surface should be leveled to within 1/8 inch in ten feet; and all constructions seams, expansion joints, and holes should be filled level with the surrounding surface to eliminate telegraphing of such irregularities.
R E V . 1 1 - 8 - 1 0 Sealers: Shaw does not endorse any concrete or floor sealers against moisture. IF MOISTURE IS PRESENT, DO NOT INSTALL FLOOR. Some sealers will protect the installation against alkalinity. Some also serve as a barrier between old and new adhesives to deaden old adhesive tack, prevent plasticizer migration and seal over dust or old cutback adhesives. Most latex- and acrylic-based sealers are compatible with Shaw adhesives.
R E V . 1 1 - 8 - 1 0 Bond Test: To determine if a subfloor is compatible to Shaw adhesives, or to determine if the porous or non-porous adhesive application method is required, use this test: Using the flooring and adhesive suitable for the subfloor, install a 2’x2’ section following the recommended installation procedures Select areas next to walls, columns, or other light traffic areas. Tape the perimeter with duct tape to prevent edge drying of the adhesive.
R E V . 1 1 - 8 - 1 0 INSTALLATION FOR TILE Layout of the Room for Squarely Laid Fields To square the area to be covered, first find the center of one end of the main rectangle. Locate the same point at the other end wall. Snap a chalk line between these points to mark the center line on the floor. Then measure along this center line to find the middle of the room. Fig. 1 At the center point, mark off a line across the room at exactly right angles to the first line.
R E V . 1 1 - 8 - 1 0 Array-Grout □ Stain Resistance □ Premixed □ No Shading □ Resists mold and mildew Coverage: Joint Width 1/16 “ 1/8 “ 1/4 “ Coverage per gallon 500 sq. ft. 300 sq. ft. 140 sq. ft. Product Description: Array-Grout, with a unique formula, offers stain resistance color consistency and a smooth texture for easy spreading and clean-up. Uses: For Grouting Shaw Calcutta tiles.
R E V . 1 1 - 8 - 1 0 INSTALLATION FOR PLANK Layout of the Room: Find the center point of the room. Strike a line. Obtain a true 90’ angle by using a carpenter’s square. Strike a second line which will divide the room in to four equal parts. Measure the distance from the center to the wall, parallel to the direction of the plank. Divide the measurement by the width of the plank. If less than half remains as the border plank, adjust the point to compensate.
R E V . 1 1 - 8 - 1 0 TROUBLE SHOOTING TIPS Occasionally, problems can arise during installation or during the life of the floor. The following information has been compiled as a way to prevent failures from occurring. More than seventy-five (75) % of installation related failures are due to improper use of adhesives. Problem: 1. Tiles not adhering to subfloor with little to no adhesive transfer. 2. Tiles curling up or releasing at the edges. 3. Product is well bonded in some areas but not in others.
R E V . 1 1 - 8 - 1 0 Problem: Product is well bonded in some areas but not in others: Causes: • • • • • • • Since adhesives do not fail selectively, you must look elsewhere for the cause. Spreading more glue than can be covered with product in the allowed amount of time (this will occur mostly with wet-set adhesives). Improper rolling in areas or rolling too late. Some underlayment panels may absorb adhesive liquids faster than others.
R E V . 1 1 - 8 - 1 0 Problem: Adhesive becoming “wet” or “gummy” some time after installation; Causes: • • Moisture present in subfloor Old cutback adhesive from prior installations or contaminants breaking down the adhesive. Problem: Gaps between tiles which are corresponding with underlayment joints. Causes: • Shrinkage or separation of the underlayment panels Problem: Tiles coming loose with adhesive dry and powdering: Causes: • High alkalinity in subfloor.
