CMS Bond 100 High Performance Acoustic Sealant for Use with Regupol 4515 Eco (REGUPOL sonus eco) Soundproof Underlay

CMS Bond 100 is a solvent free low VOC high performance water based acrylic dispersion with very good bond strength. It is suitable for plasticized vinyl floor coverings (3mm only) (including PVC tiles) together with high density foam backed carpets.


CMS Bond 100 is distributed in the UK by CMS Danskin Acoustics. The adhesive manufacturer will guarantee the performance and quality of products against manufacturing defects provided they are used in accordance with our relevant Technical Data Sheets at the time of installation and the appropriate sub floor preparation has been undertaken in accordance with the relevant British Standards.

Floor covering manufacturers are constantly introducing new backings and improving their current products. Certain backings may have unique characteristics which may influence the choice of adhesive used. Whilst every effort has been made to ensure the information is correct at the time of publication it is the responsibility of the user to ensure that the product is suitable for the particular installation.
If there is any doubt as to the use of our adhesives the installer should contact CMS Danskin Acoustics for advice or carry out their own tests to ensure compatibility.

Important steps before you lay CMS Bond 100 – Surface Preparation

Suitable sub-flooring substrates include concrete, flooring grade hardboard, plywood, chipboard, sand/cement screed, proprietary good quality self-smoothing underlayments. Asphalt and surface membranes should be treated with at least a 3mm coating of the latter before applying the adhesive.

Site conditions should comply with the latest British Standards editions: BS 8102 (Code of Practice for protection against moisture from the ground), BS 8203 (Code of Practice for installation of resilient floor coverings), BS 5325 (Code of Practice for installation of textile floor coverings), BS 8204 part 1 (Code of Practice for installation of self levelling screeding compounds), and supplementary specifications.

Surfaces must be level, firm and clean, free of loose material, mould, oil, grease, organic growth and surface moisture (under 75% RH).

Uneven, dusty or friable surfaces should be treated with the appropriate universal primer and screed.*

It is essential that suitable damp proof membranes be in place to prevent rising damp.*

Under floor heating should be turned off for at least 48 hours prior to and after application.

Particular attention must be paid to the floor covering manufacturer’s instructions. i.e. any pre storage conditions prior to fitting.

*Please contact CMS Danskin for further information.


CMS Bond 100 is a ready to use versatile product and should not be diluted or adulterated in any way.


Use a notched trowel of dimensions 1.5mm x 5mm or as CFA guidelines.

Heavy textured floor coverings may require a larger towel.

Apply adhesive evenly to the substrate and depending on the substrates lay the floor covering while still wet. It is best to allow the freshly applied adhesive to stand for 15-45 minutes depending on the ambient conditions, to build tack before embedding the floor covering.

Press firmly into place and rill using a 60/70Kg roller or glider depending on material used. Roll again approximately 1 hour after application.

Wait at least 24 hours before welding vinyl seams (3mm only).

Removal of adhesive from tools

Clean tools with water if adhesive is still wet or use white spirits if it has dried.
