Safety:
IMPORTANT: before embarking on any work involving BOSTIK KV 360 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 24 months in the original unopened container stored between +10°C and +30°C. Frost/thaw stable down to -10°C. In case of product freezing, put the bucket into the heated room (+25°C) for at least 24-48 hours. Mix well before application.
PREPARATION
Preparation should be in accordance with building standards. Subfloors must be sound, even, smooth, permanently dry and free from old adhesive residues, laitance, dust, grease or other contaminants.
When overlaying existing floor coverings, ensure that they are firmly bonded and clean.
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).
Residual moisture content must be <3% for cement screeds and <0.5% for anhydrite screeds.
All surfaces must incorporate adequate damp proofing, if not, they should be primed with EPONAL 376 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).

Hints:
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.
To 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 to ensure good transfer of the adhesive. Repeat after 30-40 minutes.
Do not weld the joints before the adhesive has had sufficient time to develop a good bond, normally 24 hours after installation.
REMARKS
- 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.
