SADERTAC S41 is a solvent-free high-performance acrylic adhesive (EC1 level) suitable for:
- PVC/vinyl floor coverings: homogeneous and heterogeneous PVC in sheet and tile, cork-PVC bonded coverings, polyolefin-based floor coverings, linoleum in sheet, rubber flooring in sheet or tile*, expanded vinyl, semi-flexible tiles;
- textiles: needlepunch with or without backing, foam-backed carpets, non-woven textile floor coverings, polypropylene (Action Bac®);
- natural fibre floor coverings (Coir, sisal and sea grass).
It can be used on sport facilities, in showers, bonding difficult flooring, inside corners, PVC onto PVC.
For use onto subfloors of concrete, sand/cement screed, anhydrite screeds, smoothing underlayments, flooring grade plywood and timber.
Recommended by main manufacturers.
For interior use only.
* For high traffic and mechanical cleaning-up, use our 2-component polyurethane adhesive.

PREPARATION
Preparation should be in accordance with building standards. Subfloors must be sound, even, smooth, permanently dry and free from old adhesive residues, dust, grease or other contaminants.
When overlaying existing floor coverings ensure that they are firmly bonded and clean.
Remove dirt, polish, oil and similar contaminating substances.
When further preparation of the subfloor is required, select suitable Bostik primers and Bostik smoothing and levelling compounds. Very absorbent surfaces must be primed to prevent over absorption.
All surfaces must incorporate adequate damp proofing, if not, they should be primed with EPONAL 336 Moisture Vapour Barrier coating.
Always allow primers and self-levelling and smoothing underlayment to dry thoroughly before applying the adhesive.
APPLICATION
Apply an even coat over the whole area to be covered using a suitable notched trowel (depending on the porosity and roughness of the substrate).
For all coverings with a smooth, polished underside use notched trowel A2: apply approx. 200 g/m².
Hint: To minimise the effect of the adhesive serrations showing through thin floor coverings, apply with a trowel and flatten with a foam roller, taking care to pre-wet the roller with adhesive.
For all coverings with a rough underside, use notched trowel N°2: apply approx. 300 g/m².
Avoid puddle formation. Allow an appropriate waiting time: approx. 10 to 15 minutes, depending on temperature and humidity conditions; substrate absorbency and type of floor covering. Lay the floor covering whilst the adhesive remains tacky and receptive. Use a rubbing block and/or roller to expel trapped air and ensure good transfer of the adhesive. After 30-40 minutes, repeat.
Bonding PVC onto PVC, impervious surfaces: waiting time can vary from 30 to 90 minutes depending on ambient conditions and the quantity of adhesive applied.
Do not weld the joins until the adhesive has had sufficient time to develop a good bond, normally 24 hours after installation.
REMARKS
- Always observe an appropriate drying time.
- Tightly close all containers after use.
- Suitable for rubber floor coverings for which the manufacturer recommends an acrylic adhesive
Cleaning
Tools should be cleaned with warm water, preferably whilst the adhesive is still wet.
