General:
A Tarkett Corner Roller is used to obtain smooth junctures when coving.
Adhesives: use the same adhesives approved for Tarkett’s homogeneous vinyl floors, for example a water dispersed acrylic adhesive. Follow the manufacturer’s directions.
The floor is joined and hot welded with welding rod. For the best result, use a speed welding nozzle.
For removal of excess welding rod use a special trimming knife or an equivalent tool. Use a water-resistant levelling compound for all subfloor proprietary work in areas where wet conditions exist. When marking, only use a lead pencil.

Preparation
The substrate must be smooth, level, dry, clean and free of all foreign material in accordance with the specifications of local flooring authorities. Subfloors made of particleboard shall be installed according to the respective manufacturer’s directions.
The flooring is coved to approximately 10 cm (about 4 in.) up the wall. If a wallcovering is to be installed, then it should overlap the wall base by at least 3 cm (about 1 in.).
For best results, the top section of the coved material should be tapered off gradually to the wall using an acrylic filler / body filler or a levelling compound to achieve a smooth finish prior to installing the wallcovering.
If the subfloor is painted, damp-proofed or non-absorbent, then you must allow the adhesive to become “tacky” before installing the floor. Seams are not recommended within a 0.5 m radius of floor drains. Contact Tarkett if unsure about any part of the installation.

Handling and Installation
The manufacturing batch number of the rolls must match for the installation. Save the details for each roll until the installation is completed.
Reverse sheets whenever possible.
The rolls shall be stored in an upright position.
Before installation, the material should be allowed to reach room temperature.
Report material defects to your nearest Tarkett regional office/dealer. Be sure to state the colour and roll number found on the control card of each roll.

Installation
The floor is always installed at room temperature. The temperature of the room, however, should not be lower than 18° C (about 65° F). Cut length sizes required. If possible, let them lay flat out to allow the material to relax and adapt to room temperature. This is especially important for long lengths.

Fitting, coving and corners
Using a straight edge and pencil, mark up wall to a height of about 10 cm (about 4 in.) all walls where the flooring will be coved.
Apply the adhesive on the walls up to the marked line, using a fine notched trowel. Spread some of the adhesive out on to the floor, as shown in the picture.
Whilst the adhesive becomes tacky, the sheets are cut. The sheets should be cut longer than the room length to allow sufficient material for coving.
When a sheet fits the width of the room, make a cross mark on the bottom of the material and the subfloor to indicate the centre. This will help you place the sheet in its exact position. The cross marks should coincide when placing the material.
When the width of the room exceeds the sheet width (more than one piece has to be installed to cover the area), mark a line on the floor parallel to the longitudinal wall at a distance equivalent to 12 cm (about 4.5 in.) less than the sheet width.
Mark the room’s centre on this line. On the bottom of each sheet, mark their centre. The cross marks on the subfloor and sheets shall coincide.
Fold back and loosen the sheets covering half of the floor area. Apply the adhesive on the subfloor with a fine-notched trowel. Use a soft brush around drains and hard-to-reach areas.
Around and inside drains, use contact adhesive. Follow the respective manufacturer’s instructions for the adhesive you have selected.
Use a corner roller to press the material firmly into the juncture between the floor and wall. In areas where one sheet is sufficient to cover the subfloor, the adhesive can be applied over the entire surface area before installing the sheet.
Although this requires experience, it is the fastest installation method.
When fitting in-corners, make a cut in the excess material starting about 5 mm (about 1/4 in.) above the floor in the corner. The material has to be heated before folding, heat the area between the sheet and the wall.
This provides better contact between the sheet and adhesive.
Press the material firmly into the corner with a corner roller.
The corner seam shall be placed on one of the walls at a 45-degree angle.
When fitting an out-corner. The sheet is folded against the corner and cut about 5 mm (1/4 in.) from the floor.
The guidelines in the picture show the corner on the sheet and the position of the cut at about a 45-degree angle.
Then a diagonal cut is made as shown.
To adhere the triangle-shaped piece more simply and securely, cut a groove on the back of the triangle with a corner knife.
The depth of the groove shall be no deeper than half of the sheet thickness.
The triangle can now be folded and placed on the corner. It will overlap the coved floor.
Cut through the overlapping material to make a tight fit.
Use a hot-air gun for welding with welding rod at inner-corners and outer-corners.
Use a speed welding nozzles specially designed for welding vinyl floors.
For a perfect job, a repair gun is usually required to effectively seal all seams nearest to the floor.
Around pipes by walls, cut the sheet and press it against the pipe to form a collar. In tight or cramped areas between pipes and walls, cut as shown by the dotted line. If a cover is required, do the following:
1) If you make a cover out of floor material, fit it against the pipe with adhesive. Weld the seams together using a repair gun.
2) Prefabricated covers are applied according to the manufacturer’s instructions.
Seam sealer or sealing compound (silicone, Aquatät or equivalent), approved for this purpose, can be used for an extra tight fit around pipes. Apply it between the subfloor and sheet vinyl.
Around drain pipes, fold the sheet against the pipe and mark a line on the material where the centre of the pipe is. Cut the hole at the start of the fold.
Heat the sheet vinyl and press it over the pipe.
Trim off excess material with a hook knife so that the break in the pipe wall is covered.
Around flush drain openings, heat the sheet and mark the location of the drain using a clamp ring.
Then cut a small hole in the centre of the drain within the mark. Heat the flooring and press the clamp ring down into the edge of the drain. When using an adjustable clamp ring, make sure it fits tightly. Trim the material around the perimeter of the ring. For extra sealing, a layer of silicone is put between the sheet and the edge of the ring.
All welding seams are grooved with a grooving machine or a seam grooving tool with a hard-metal blade.
Weld with hot-air and a speed welding nozzle.
Do not heat weld until the adhesive is completely dry, normally one day after the installation.
CAUTION: Welded seams must cool to room temperature before trimming. Start trimming where you began welding. All trimming of welding rod is recommended in two steps: rough and fine trimming. With a trimming knife rough and fine trimming can be done by turning the knife. When fine trimming welding rod, turn the grooved side up.
