Subfloors should be clean, dry and flat and prepared in accordance with BS 5325. Timber floors should be covered with plywood or other appropriate sheet materials.

1. Wherever possible lay the carpet down the length of the room to minimise the number of joints. Avoid joints in doorways and high density traffic areas. Measure the length of the room, and cur the first piece from the roll allowing an additional 75mm for trimming. Ensure and allowance is made for doorways, alcoves and any irregularities of the walls. Starting at the corner furthest from the door, lay the first piece into position lapping up the walls at both ends sufficient for trimming.

2. Run a pencil along the inner edge of the flooring making a guide line on the floor for the application of adhesive.

3. Fold the sheet half way back taking care not to disturb the positioning of the flooring. Apply the recommended adhesive onto the subfloor using the application techniques previously described, from the wall to within 20cm of the guide line. Replace the carpet carefully and accurately back into position and roll to ensure overall contact with the adhesive. Repeat for the other half of the sheet.

4. Measure and cut the second piece from the roll. Position the second piece with the edge overlapping the first by approximately 5cm and mark a guide line on the floor with a pencil at the next seaming edge.

5. Fold the sheet half way back taking care not to disturb the positioning of the flooring. Apply the recommended adhesive onto the subfloor using the application techniques previously described, from 20cm inside the first guide line to 20cm inside the next. Replace the carpet accurately back into position and roll with a 68kg flooring roller to ensure overall contact with the adhesive. Repeat for the other end of the sheet. Successive lengths may be installed in this way.

6. Using an Araseur or sharp knife trim the carpet to fit against the perimeter walls.

7. Position a straight edge along the middle of the overlap and cut through both pieces of carpet with a sharp knife and remove the surplus. Fold back the seam edges and apply adhesive onto the subfloor with a notched spreader. Re-lay the carpet and roll with a 68kg flooring roller to ensure overall contact with the adhesive.

8. When the floor has been completely covered re-roll the area again to maintain good adhesive contact.
