WPC TILE Installation Instructions

GENERAL GUIDELINES

All instructions and recommendations are based on the most recent information available. They should be followed for

an ideal installation. Failure to follow these guidelines may result in installation failures. EarthWerks® is not liable for

improper installation practices beyond our guidelines and current industry standards.

1. This product should be stored at the jobsite in a climate controlled area with an average temperature between

55-85⁰ F (13-29⁰ C). All areas where product will be installed must have a working heat and air conditioning source,

operational for a minimum of one week prior to installation and remain in operation during and after installation.

Conditions should be at the same temperature and humidity level expected during normal use (between 55-85⁰

F / 13-29⁰ C with relative humidity no greater than 65%). This product should NEVER be installed outdoors.

2. Product should only be installed after the jobsite has been cleaned and cleared of debris that could potentially

damage a finished tile installation.

3. During the WPC Tile installation, mix and install tiles from several different cartons to minimize shade variation.

4. The finished WPC tile installation should be protected from exposure to direct sunlight.

SUBFLOOR INFORMATION

Although this WPC Tile locking system is designed to be a “floating” floor installation, proper preparation of the subfloor

is still a major part of a successful installation. Roughness or unevenness of the subfloor may telegraph through the new

floor. Unevenness in the subfloor can also cause problems with the integrity of the locking system and possibly cause the

locking system to disengage. All subfloors should be smooth and flat with the tolerance not exceeding more than 1/8” in

a 6’ span. All subfloor and underlayment patching must be done with a non-shrinking, water-resistant Portland cement

patching compound.

A. Concrete Subfloors

1. Concrete subfloors must be dry, smooth, and free from dust, solvent, paint, wax, grease, oil, asphalt sealing

compounds, and other extraneous materials. The surface must be hard and dense, and free from powder or

flaking.

2. New concrete slabs must be thoroughly dry (at least six weeks) and completely cured. The final responsibility for

determining if the concrete is dry enough for installation of the flooring lies with the floor covering installer.

3. Holes, grooves, expansion joints and other depressions must be filled with a Portland cement-based underlayment

and troweled smooth and feathered even with the surrounding surface.

4. Concrete floors with a radiant heating system are acceptable, provided the heating system is embedded into

either the concrete or covered with a Portland cement based self-leveler. Heating system must be covered with

a minimum ½” separation between the flooring and heat source. The temperature of the subfloor must not

exceed 85°F at any point. Before installation, turn on the heating system to eliminate any residual moisture.

B. Wood Subfloors

1. Wood subfloors must be suspended at least 18” above the ground. Adequate cross-ventilation must be provided,

and the ground surface of a crawl space must be covered with a suitable vapor barrier.

2. Wood subfloors directly on concrete or installed over sleeper construction are NOT suitable for the installation.

3. All wood and wood composition panels, including plywood, OSB, flake board, and particle boards can be used

providing they are smooth, flat, structurally sound, and free of deflection.

4. A 1/4” underlayment panel should be installed over the subfloor if the surface of the wood subfloor is not smooth.

C. Existing Floor Coverings

1. WPC Tile products can be installed over most existing hard–surface floor coverings provided the existing floor surface is smooth, or can be made smooth. 2. When installing over ceramic tile it is best to smooth the grout lines and texture with a cement patch or leveling compound. Smooth ceramic with narrow grout lines may be suitable without the need for a cementious overlay. 3. Heavily cushioned vinyl flooring or vinyl flooring consisting of multiple layers are NOT suitable subfloor for installation.

10. Using gentle force and at a 20–30 degree angle, push the long side tongue into the groove of the adjoining tile by sliding along the short side seam. You may need to lift the tile to the left of it slightly to allow for the “sliding” action. 11. The remaining tile can be installed in the room using the same technique. Make sure the required expansion gaps are maintained against all fixed vertical parts (such as walls, doors, cabinets etc).

Preventative maintenance is a must with any type of flooring. Please use entry mats to stop as much dirt prior to entry of the building. Make sure all furniture is well protected, avoiding rubber products as they can cause stains. Use hard plastic or felt pads under heavy furniture to prevent point loads. Use flat, polished metal glides with a minimum 1” diameter under chairs and stools. These should have a rounded edge and pivot to remain in flat contact with the floor.
