The subfloormust be level, flat, clean, free from marks (no felt pen, marker of any type, ballpoint pens, paint, etc., that could cause discoloration due to migration) sound, dry, solid, hard, smooth (the absorbency must be checked) and not exposed to moisture.
The preparation/dryness of the subfloorand installation procedures should all be in accordance with the current relevant Standard within the country of use. The dryness of a solid subfloorshould be below the maximum moisture level permitted when tested in accordance with that Standard.
E.g. in the UK, the relative humidity of concrete surfaces must be below 75%, and less than 2% with the CCM method.
In North America, ASTM F-170 recommends a water-to-cement ratio of 0.40 to 0.45.
Before selecting a smoothing compound, check what type of traffic the floorcoveringwill be subjected to once installed. Latex smoothing compounds are not suitable for areas that will receive heavy traffic, especially heavy, narrow wheeled traffic (see EN 12529, Castors and wheels). Check levelling compound compatibility, and follow the instructions of the levelling compound manufacturer.
Note: exclusion of liability (adhesives, levelling compounds, etc.)
Although Tarkett may list a selection of adhesive, levelling compound and surface damp-proof membrane manufacturers and types, we do not guarantee the products listed. The list of products and manufacturers is not guaranteed complete or current.
Tarkett will accept no liability for any of these products failing to perform in conjunction with any of its products. It is theresponsibility of the adhesive, levelling compound and surface damp-proof membrane manufacturer and flooring contractor to ensure the products being used are appropriate foruse and applied in accordance with the manufacturers’recommendations.
Glue with an acrylic adhesive emulsion recommended by Tarkett. Apply 250 to 300 g/m2using a finely serrated trowel.
In some areas, it is recommended to cove the flooring up the wall.
Plan the sheet direction for the area to be installed to ensure whenever possible that joins do not coincide with doorways, main traffic lanes, sinks or urinals.If the room is reasonably square, the sheets should run parallelto the incoming light. In long, narrow rooms it is best to install the sheets along thelength of the room.Cut the sheets to length. If coving is necessary, the sheets should be cut longer than the room.
All consecutive sheets should be installed in the opposite directionto the previous sheet installed, except for Gemstone, which is laid in the same direction.Butt join when edges are straight, or overlap the edges by 3 cm and trim the two sheets simultaneously.
Before starting tile installation, determine the method of laying taking into account the shape of the room and the design to be laid. See the various methods on the separate sheet.Install the tiles edge to edge and flatten by hand as they are placed.
Hot welding with a welding rod is recommended for rolls and for tiles.
Important! Do not weld until the adhesive has bonded completely (wait 24 to 48 hours).
Groove the joints using a hand grooving tool or a machine beforewelding.
Weld with hot air and a Tarkett Speed Welding Nozzle or equivalent.
