Installation Guide for Photosorption Acoustic Panels using Special Mastic/Adhesive

Photosorption  are simply bonded to the walls with our special Mastic/Adhesive.

The panels and adhesive must be kept and stored inside at normal room temperature at all times and fully acclimatised in the area they are to be installed for at least 24 hours before fixing.  To avoid soiling the diffusers, cotton gloves should be worn when handling them.

The substrate must be clean, flat, dry and free from oil, dust and grease or any other residue that could affect the bonding of the Diffusers.

The mastic/adhesive comes in ready to use cartridges and is applied with the aid of a skeleton gun.  It adheres immediately upon contact.  However, it is still possible to adjust the panels within 2 minutes after adhesion.  Pressure must be applied evenly over the panel upon contact; care must also be taken to not to damage the face of the diffuser by pushing too hard.

A bead of the adhesive is applied to the back of the panel around the perimeter and several bead stripes are applied across the back of the panel ensuring that enough are applied to ensure adequate adhesion of the diffuser.

The adhesive takes about 24 hours to cure to full bond strength but it is strong enough to hold the panel after a couple of minutes of pressure.

One cartridge of adhesive is usually sufficient to bond a 1200 x 900mm panel.  ¾ of a tube for the 900 x 600mm panels and ½ tube for the 600 x 600mm panels.  We strongly recommend a test adhesion is conducted before proceeding with full installation.
