Lees Carpet Tiles are intended for installation on dry, properly prepared floors. These products are not intended for installation on walls, outside use, or wet surfaces.

Lees is not responsible for any product failure if proper floor preparation and/or installation procedures are not followed. The required adhesive is Lees Pressure Sensitive Adhesive. It is the responsibility of the installation contractor to make certain the floor is properly prepared and suitable for the installation of Lees Carpet Tiles.

The floor should have a minimum temperature of 65°F for at least 72 hours prior to installation and 48 hours after installation. Temperatures should not exceed 90°F. Relative humidity above 65% will adversely affect the adhesive and primer.

Installation of Lees Carpet Tile on a floor outside the scope of the guidelines in this document will void all applicable warranties.

The floor must be sound and dry prior to the installation of the Modular System. Any curing chemicals, sealers, or other chemicals must be compatible with the Modular backing system and Lees Pressure Sensitive Adhesive. Completely remove all wax, dirt, grease, paint, or old adhesives including cut back adhesive. DO NOT use solvents to clean the floor. DO NOT use oil based sweeping compound. Do not install over Resin Base Curing compound.

The floor should be flat to within 1/8” in 10 ft. Cracks, holes and depressions should be filled using a Portland based patching compound. Use leveling compound when required.

Sweep and vacuum the floor. Smooth, nonporous floors should be damp mopped prior to installation. All dust must be removed to insure proper adhesion.

All Gypcrete floors or substrates that have excessive dust must be cleaned, then primed with an approved primer or a latex milk additive.

Concrete: Prime only if floor has excessive dust. Note: Any existing sealer or primer should be tested for compatibility to the Lees Squared Pressure Sensitive Adhesive. Terrazzo, Marble, Vinyl Tile (VAC or VCT), Linoleum and other smooth nonporous surfaces do not require priming. Damp mop only. If patching is required on these areas, prime the patched areas.

The starting point in a modular installation must be as near to the center of the room as possible and must be positioned to utilize the largest perimeter cut module size.

Snap a chalk line parallel to one major wall bisecting the starting point. It may be necessary to offset the center chalk line to assure perimeter modules will be at least half size.

A second chalk line must be snapped from the starting point at 90° to the first line. This can be accomplished using a 6-8-10, or larger triangle, depending on the room size.

(See Illustration A) Meters or feet may be used to lie out the triangle in these proportions.

It is very important to install Lees Carpet Tiles in the order they were manufactured. This is easily accomplished by selecting pallets in sequential order and following the numbers located on each carton of tiles. Typically an installation will begin with the lowest carton numbers and progress through the highest numbers until the project is complete. Installing Lees Carpet Tiles by carton sequence will assure the most even uniform look possible.

installation, mark off a small area of the subfloor and determine the adhesive spread

rate. This will allow you to determine the proper coverage level and amount of

pressure to apply to the roller during installation. The installer must gauge the

adhesive spread rate.

is smooth and/or sealed, it still requires a proper coating of adhesive.

immediately after adhesive has dried. To determined if the adhesive is dry, press finger

into adhesive. When dry, adhesive should not transfer to finger.

Begin spraying by holding the wand approximately 20"off the floor at a 45 degree angle.

Allow the adhesive to become tacky, but not completely dry. The adhesive should be tacky enough that the tiles do not slide around, but wet enough to achieve transfer to the backing.

Set-up time will vary in different climates.

Roll floor with 75 to 100-pound roller.

Start from the intersection point in the center of the floor. Install the tiles in one quadrant using the chalk lines as guidelines. Fill in the area in between the two chalk lines using the stair step method.

All arrows on the tiles must be turned in different directions. Although there is no specific directionality that the installer must follow, products specified “Multi-Directional” cannotbe installed with arrows facing the same direction on touching tiles. Mixing tiles from various boxes during installation will further blend color and design elements. This process is essential for achieving optimal aesthetics.

Continue to install tiles in a stair step or pyramid pattern, starting at the center point. Check to make sure the tiles are properly aligned at edges during the installation.

Fit the tiles together by sliding them together, being careful not to trap face yarns between or under the edges of the tile. Press or roll the tiles into the adhesive. They may be removed at any time and repositioned.

All carpet tiles should be rolled with a 75 lb. or 100 lb. roller.

Cuts are made from the back. Install border tiles by placing the tile face down exactly on top of the last row of field tiles, keeping the arrows pointed in the same directions. This will be your cut tile. Using another tile, butt it against the wall allowing it to lie on top of the tile that is to be cut. Using this tile as a reference tile, score a line on the back of the tile that is to be cut. Cut the tile along the reference line being careful not to cut through the installed tile below. Install the cut tile with the cut edge along the wall. Use this same technique at doorways and other objects t hat must be cut around. A transition strip must be used to protect any exposed edges.

Do not allow traffic on tiles unless they are anchored at control grids and perimeters. When heavy furniture are wheeled traffic is moved in over tiles, use plywood runners to avoid tile shifting.

Chair pads are not required, but are recommended for use under chairs with roller casters. Casters should be the flat round type with 5/8” to 1” width minimum. If chair pads are not used, the appearance of the carpet tile will decrease. Maintenance and/or shifting of the modular may be required more frequently if pads are not used.
