- Cut to suit a variety of different batten widths, giving greater flexibility when selecting the batten size.
- Only 6mm thick, therefore minimises floor heights, which can often be the disadvantage in using standard “off the shelf” products.
- Fix to the top or bottom of the battens.
2.Please ensure each roll of Regupol® 3912 Acoustic Underlayment is completely unrolled, turned over and left in the area to which it is to be applied for a minimum of 6 hours or ideally overnight prior to cutting and installing.
Laying Regupol® 3912 Acoustic Underlayment
1. Bond Regupol® 3912 Acoustic Underlayment to the base floor. The Regupol® 3912 Acoustic Underlayment should be bonded to the subfloor using one of our recommended adhesives – please contact CMS Danskin for a list.
Please ensure the adhesive guidelines are followed at all times.
2. Lay the Regupol® 3912 Acoustic Underlayment into the adhesive and press from the centre outwards to exclude air and ensure overall contact with the adhesive.
3. Roll the Regupol® 3912 Acoustic Underlayment with a 68kg flooring roller, from end to end and side to side to ensure overall contact.
4. Please leave a minimum gap of 3mm around the entire perimeter to allow for expansion and contraction. Do not butt the Regupol® 3912 Acoustic Underlayment against the skirting boards and/or carpet grippers.
5. Use a craft knife and straight edge for cutting to size and please ensure that all edges are butt jointed.
6. After 30 minutes, when the floor has been completely covered, roll once again to ensure contact is maintained.
7. Please do not apply loads or move furniture on the Regupol® 3912 Acoustic Underlayment until the adhesive has fully set. Please refer to the adhesive manufacturer’s installation guidelines for curing times.
Important steps before you lay Regupol® 3912 Acoustic Underlayment
The recognized technical rules of the industry, and the code of practice requirements of BS8203 2001 “Installation of Resilient Floor Coverings” are to be observed. Regupol® Acoustic Underlayments can be easily installed provided BS 8203:2001 and our installation guidelines are observed.
Please note that Regupol® 3912 Acoustic Underlayment consists of PUR foam and no rubber crumb. When comparing alternative products please be cautious where a ‘direct equivalent’ is offered. Many alternatives consist of a rubber compound which can cause plasticizer migration when used with certain floor finishes. CMS Danskin will not accept liability for products sold as a Regupol® 3912 equivalent.
CMS Bond 100 High Performance Acoustic Sealant for Use with Regupol® 3912 Acoustic Underlayment
based acrylic dispersion with very good bond strength. It is suitable for plasticized vinyl floor coverings (including PVC tiles) together with high density foam backed carpets.
- 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.
- 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.
Clean tools with water if adhesive is still wet or use white spirits if it has dried.
