LAYING ACOUSTIC UNDERLAY

1. The sub-floor must be level, sound, dry and free from dust, grease and other contaminants.
   
   It must be free from excessive moisture with a relative humidity not exceeding 75% (in accordance with BS5325). A hygrometer test should be performed in all new buildings to check for excessive levels of humidity.
   
   
2. The Acoustic Laminate Underlay should be laid foil side down (essential to ensure maximum resistance to moisture from the sub-floor) with each roll of underlay closely butted-up. The underlay should be trimmed-in flush to the walls.
   
   
3. Tape all joins with PVC Tape and press firmly into place. PVC tape used in conjunction with a recommended underlay creates a new, moisture resistant sub-floor onto which the wood flooring is fitted.
   
   
4. Once the flooring has been fully laid, trim the underlay to the top of the flooring, fit skirting or quadrant to finish.
