SADERFLEX 805 D is a fast-set multi-purpose acrylic adhesive.
Especially designed for use on building sites - excellent quality/price ratio.
Low solvent content: <5%.
It is suitable for PVC/vinyl floor coverings: heterogeneous PVC sheeting and tiles, cork-PVC bonded coverings, expanded vinyl, semi-flexible tiles; and textiles: needlepunch with or without backing, foam-backed (latex) carpets, non-woven textile floor coverings, polypropylene (Action Bac®), rubber-backed natural fibre floor coverings (coir, sisal and sea grass).
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.

Safety:
IMPORTANT: before embarking on any work involving SADERFLEX 805 D the separate Product Safety Data Sheet must be studied carefully by those carrying out the work.
Observe good hygiene in use. Avoid skin and eye contact.
Shelf life:
Up to 12 months in the original unopened container stored between +10°C and +30°C. Frost-sensitive.
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. Anhydrite screeds as well as particleboards and plywood should be primed with solvent-based primer IMPREGLUE, several subsequent coats may be necessary (100-120 g/m²/coat).
All surfaces must incorporate adequate damp proofing, if not, they should be primed with EPONAL 336 Moisture Vapour Barrier coating.
Always allow primers and 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 N°01: apply approx. 250 g/m².
For all coverings with a rough underside, use notched trowel N°02: apply approx. 350 g/m².
Avoid puddle formation. Allow an appropriate open time: approx. 5 to 10 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.
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 cure 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.
