The subfloor should be smooth, level, dry, dust and grit free (It is easier and better to vacuum the sub floor rather than just sweep it).  Any oils, grease or solvents should be thoroughly cleaned off the subfloor prior to installation.

The carpet tiles can be installed over concrete, timber, metal, ceramic or stone surfaces. Indentations / grout lines / gaps  should be filled, high spots sanded down and any loose boards / tiles / sheets firmly fixed.

The subfloor, carpet tiles and adhesives should all be acclimatised to the same normal room temperature, which is usually 15° to 20°C.

Lay out some tiles in a dry run along each arm of the cross and see what sort of spaces you’re left with around the edges of the area. The aim is to keep full (or very near full) tiles in all entrances and to have cut tiles more or less the same size all around the perimeter trying to avoid awkward corners or narrow slivers.  If necessary, alter the position of one or both lines to arrange this.  With a piece of chalk or pencil, mark on the subfloor the approximate joint position for what will be each row of carpet tiles in the length and width of the area.

You will proceed to install one segment of the area first.  In most domestic circumstances, it is not necessary to fully adhere all of the tile.  We suggest that you apply the Pressure Sensitive adhesive to the subfloor so as to adhere 10 cm each side of each join between the tiles. 

Pressure Sensitive adhesive dries on the subfloor but remains sticky so as to grip to the rubber backing of the tile.  Damaged carpet tiles can be peeled up off the adhesive and replacement tiles installed.

Fix the perimeter tiles with residue free double sided tape. Body tiles can be loose laid in most circumstances.

Installation areas subject to movements of heavy rolling equipment also require fixing with residue free double sided tape to avoid tile displacement.

When positioning tiles on the floor and butting them up against neighbouring tiles lead in with a corner, then one edge and then the other edge.

Where a part tile is required, cut from the back using a straight edge and a sharp utility knife. Once the blade has cut through the rubber backing and carpet base, the pile may be gently separated by pulling the two sections apart.

A way of preparing part tiles to be fitted at the perimeter is to simply turn the tile to be cut over and place it under the edge of the whole tile abutting it with an edge up against the base of the wall. Using the abutting tiles outer edge and the straight edge, as a cutting guide, cut through the upturned tiles rubber backing and fibre base, remove the whole tile and gently separate the pieces. Turn the piece to be fitted the right way up and fit it with its newly cut edge against the skirting.

For more complicated shapes, such as curves, pipes, external corners, etc, cut a cardboard template to size first and use this to cut around.  Remember to turn over both the tile and the template to cut from the back.

Excellent clean-ability by standard methods ensures the tiles retain their original appearance longer.  A regular maintenance program of vacuuming and sponging up most spills with a mild domestic detergent mixture is all that’s normally required.  Always rinse off detergents with a clean damp sponge remembering to dab rather than rub the surface pile. 

Install large door mats (eg. 1 m x 2 m) at all entrances to the premises.

Periodic use of Extractive Hot Water (steam) cleaning removes heavy soiling. Dry wet tiles in the shade.
