This is an underlay assist product that should be placed underneath underlay to work as a moisture barrier and make the subfloor easier to install. It is useful for those underlays that don't have DPM built in. It both prevents moisture damaging your floor and offers extra comfort.

This product is 5m long and 4m wide, and suitable for all types of wood and laminate flooring as well as wood and concrete subfloors. It is also suitable for underfloor heating.

This product comes with a 15 year guarantee for that added peace of mind.

Solid and Engineered Wood Flooring Installation:

1) A “floating floor” is an extremely popular fitting method, this is where you run a PVA wood glue along the groove and slide the tongue back into the groove creating a strong bond. This method then allows the floor to naturally breathe as it is not fixed to one position. Underlays are often used when this installation method is used.

2) Fixing the flooring directly to the sub floor is equally as popular as a “floating floor”. You can either stick the flooring directly to the sub floor with an adhesive or secret nail the flooring to a wooden sub floor. This is the preferred method when installing solid wood flooring.

Laminate Flooring Installation:

Laminate flooring is one of the easier installation methods as it comes with click joining system. This means two planks simply just click together. Most people opt to use an underlay when installing laminate flooring.

Here are a few important tips:

  • Don’t forget to leave a 10mm expansion gap.
  • Allow 48 hours for an engineered floor to acclimatise
  • Allow 7 days for a solid wood floor to acclimatise.
  • Allow 24 hours for a laminate floor to acclimatise.
  • Try and install on a level sub floor
