How to Lay the Engineered Wood on Floor?

Where to lay the engineered wood on floor?
Engineered wood flooring can be laid directly onto the sub-floor or an underlay based on the following systems:

  1. Direct Lay to Sub-floor
  2. With Underlay and Fixed
  3. With Underlay and Floating

 

Direct Lay to Sub-floor

For direct laying of engineered wood, the flooring strips are glued to the sub-floor using compatible adhesive. This is effective for sub-floor that meets evenness tolerance. This method of laying provides a solid feel for the user.

 

With Underlay and Fixed

The engineered wood flooring strips are glued to an underlay (plywood, rubber or felt) which is fixed to the sub-floor using suitable adhesive and/or nailing. If plywood is used, it is recommended to use Water Boil Proof (WBP) plywood.

 

With Underlay and Floating

The underlay is not fixed to the sub-floor and the engineered wood flooring strips are installed without fixing to the underlay. This method provides a floating feel.

 

The underlay can accommodate sub-floor unevenness (within 3 mm in 2 metres) and provide a smooth surface to receive the engineered wood. However, this should not be used as the solution to correct the levelness of the floor screed.

 

The underlay helps to cushion the flooring and makes it comfortable to walk on. Some underlays also act as a moisture barrier protecting the wood from any moisture ingress from the concrete floor and dampen the sound of steps making it a friendly environment for the user and also neighbours in the lower floor.
