Preparation & Installation Of Flooring

Subfloor Preparation

  • Existing floorcoverings must be removed, and the subfloor made good before commencing installation
  • The subfloor must be structurally sound, level, smooth, dry and free from contaminants
  • New concrete and sand/cement screeds must be left for construction moisture to dry out, and the floor covering must not be laid until a hygrometer test in accordance with BS 8203 gives a relative humidity reading of not more than 75%
  • Absorbent surfaces should be primed before the application of adhesive or smoothing compound

Installation

  • The material should be allowed to acclimatise (tiles removed from their boxes) to the room’s normal operating temperature and humidity for a minimum period of 24 hours, and to be installed under the same conditions
  • Where installed over underfloor heating, the heating must be switched off at least 48 hours prior to installation, and switched back on at a low level at least 48 hours after installation, bringing the temperature up to its normal level gradually over 7 days. A maximum surface temperature of 27°C should not be exceeded
  • Carpet tiles should be installed over a full spread of tackifier adhesive, commencing at the centre of the room and working towards the perimeter
  • Sheet material should be fully bonded to the subfloor, however, in some instances an underlay system can be used – further details available on request
  • When forming the seams of a loop pile sheet material, the carpet should be cut between the two rows of loops and seam sealer applied
  • Generally, Paragon carpet tiles can be laid broadloom or chequerboard (according to preference) however due to the nature of the product, some should be laid chequerboard only – further details available on request
