Full installation guidelines are available on request. However, key points to observe are:

• Area of installation must be dry, dirt and dust free and weather tight.  If over 75% RH seal with Regupur® Regushield and for priming, if required, use Regupur® Reguprime, or equal approved. To determine RH please use a Hygrometer.

• Regupol® 4515 Multi should be unwound and left for a minimum 8 hours or ideally overnight at the place where it is to be installed, to allow for any potential shrinkage.

• The subfloor must be sound, smooth and dry. A self-levellin compound such as Regupu Regulevel 2 or equal approved may be required to achieve the desired ‘SR’ value. **

• Regupol® 4515 acoustic underlays can be easily installed providing BS 8203:2017 and the CMS Danskin Acoustics installation guidelines are followed at all times.

• When bonding to bare concrete a suitable concrete sealer is recommended to ensure maximum adhesive coverage and  bond strength.
