When your Rubber tiles arrive please check the receipt of the tiles, check that the colours is correspondent to those ordered, that the quantity is correct and there is no obvious damage. Also Check that the tiles are from the same batch because if they are the tiles may differ from each pack. The tiles should be stored, together with the adhesive, at a minimum temperature of 18 c for at least 24 hours before installing them. The tiles should be stacked in storage no more then five boxes high during the condition period.
To achieve the best possible outcome,when laying the tiles the temperature conditions should be a similar temperature, to prevent thermally induced dimensional changes.
Installations where underfloor heating is used, this should be switched off from 48 hours prior to installation until 48 hours afterwards. it should then be brought slowly back up to the working temperature, a maximum of 27c Adhesive capable of withstanding temperatures up to 27c should be used. Where direct sunlight, sometimes in conjunction with underfloor heating, creates high surface temperature on the floor, an approved epoxy or polyurethane adhesive should be used.
The work area should now be prepared to receive the rubber tiles. Ensure all other trades have completed their work and removed all debris and sweep or vacuum the whole floor area. Check the condition of sub floor and make good necessary. Stone or power grind any cementicious sub floor to remove any nibs or ridges. Remove any surface contaminants that may affect adhesion. Sweep or vacuum again prior to laying the tiles. If required, check the moisture content of the sub floor and record the results and method used. Good lighting is essential.
layout of rubber tiles, Although many floor layers regard tiles as being easier to lay than a sheet, the layout of the tiles can be critical to the success of the installation. The regular form of tiles, especially when laid in contrasting colours, can especially when laid in contrasting colours, can accentuate deviations in the building line, emphasising the need for detailed planing of the layout. Many floor layers start in the main doorway, believing that the initial impression when entering a room is most important. However, working from the centre of the room and loose laying tiles to check the layout will make the final appearance correct from any viewpoint. This is especially important where a geometric design is incorporated into the floor.
Measuring and marking out,
- Measure the room to be laid in both directions, including any alcoves
- Mark a chalk centreline A-B ensuring that it is square to the wall with the doorway.
- Loose lay tiles away from the centrelines A-B and check that no small strips will have to be laid at the perimeter of the room. If small strips do result, move the centreline in either directions keeping it parallel to the line A-B so that the perimeter tiles will only require a small piece cutting off.
- Mark a chalk centreline C-D, ensuring that it is square to line A-B. Check Squareness with a large square, trammels or geometrically.
- Loose lay tiles away from the centreline C-D and check that no small strips will have to be laid. Adjust centreline C-D as described for a A-B
Spreading the adhesive, if the sub floor is porous, it should be primed using a primer compatible with the adhesive, as recommended by the adhesive manufacturer.
The amount of adhesive that can be spread at any one time depends upon the prevailing site condition, such as temperature, humidity and through flow of air – all of which the open time of the adhesive.
Adhesive manufacturers provide details provided details of the open time, and their instructions should be followed. ideally, the floor area should be divided into workable sections, leaving the perimeter tile areas adhered until the main body of the floor had been laid.
Ensure the backs of the tiles are free from dust prior to laying. This can be done whilst waiting for the adhesive to go off. Once the adhesive is ready to accept the tiles, place the first tile at the starting point, which is the intersection of the two centrelines. Press down well in the centre of the tile and then run your thumb around the edges, ensuring all air is expelled.
Place the next tile in position, alternating the colour if necessary tile in position, alternating the colour if necessary, and proceed down the centreline, laying two tiles wide i.e one tile either side of the centreline. It is essential to keep the tiles exactly on the centreline. Repeat the sequence along the centreline at right to the first. Then, working from the completed centrelines, finish the section taking care that tile bond is maintained throughout. Any Excess adhesive should be removed as work proceeds. When a section has been laid,expect for the perimeter, it should be thoroughly rolled, Repeat for each section until the main field of tiles has been laid
