Post Installation Guidelines

Once installed Fermacell requires 72 hours to become fully load bearing.

Firmax CP boards are capable of accepting foot traffic typical of a building site and, provided that certain precautions are followed then our system can be used as a working surface before the final floor finishes are fitted.

The system can be used as a working surface if the following precautions are observed:
  • Site traffic thoroughfares should be protected with 1 x 18mm ply. Sweep the floor before laying the ply!

  • The floor system can accept regular, normal site foot traffic after 24 hours at 20°C

  • Ladders should be used on 1 layer of 18mm ply after 24 hours

  • Towers and scaffolding should be erected on 1 layer of 18mm ply after 72 hours

  • Pallet trucks with load should be used only on 2 layers of 18mm ply after 72 hours

  • The heating system can be turned on after 24 hours – no heating-up protocol required

The Firmax CP floor is at risk of damage if the following points are not observed:

Pallet trucks of ANY kind should NOT be used directly on the system

DO NOT apply heavy/point loads at the edge of the system

DO NOT allow scissor lifts, cherry pickers to be used

DO NOT proceed with final floor installation on damaged areas

DO NOT allow any foot traffic on the system before the 24-hours has elapsed
