Installation

CMS Danskin SoundLay Acoustic Overlay Material is supplied in standard sheet/tile sizes. These are easy to lay on the floor in a staggered pattern, placing tightly together.

The SoundLay Acoustic Overlay Material sheets can be laid loose or bonded to the floor. When bonding to the floor, ensure that the surface is clean, dry, grease free and that the flooring is secured before bonding. CMS Bond 100 Adhesive should be used. The SoundLay sheets can be pushed up to the skirting board or wall; ensure a tight fit to prevent flanking of airborne noise.

Carpets

Can be installed using grippers or by bonding. Contact CMS Danskin Acoustics for advice on the selection and fitting of grippers. When bonding, ensure the adhesive is suitable for polyurethane materials, as shrinkage may occur. When bonding carpet, it is recommended that SoundLay Soundproofing Underlayment sheets are first bonded to the floor, using CMS Bond 100 Adhesive.

Laminate*

Where a wooden laminated floor finish is being used, it is recommended that a layer of 12mm T+G plywood or MDF is bonded to the SoundLay Soundproofing Underlayment first, using CMS Bond 100 Adhesive.

Vinyl

Where vinyl floor coverings are to be used, it is recommended that a layer of 12mm T+G plywood or MDF is bonded to the SoundLay first, using CMS Bond 100 Adhesive. Please note: For installations and applications not listed, please contact CMS Danskin Acoustics for guidance.

Recommended Adhesive

For bonding to the subfloor, CMS Acoustics recommends the use of CMS Bond 100 Adhesive. For further guidance please contact CMS Danskin Acoustics.

Please note, nail bound systems must not be used with SoundLay as this will compromise the material’s acoustic performance
