SADER LINO is an acrylic adhesive suitable for linoleum sheets, linoleum tiles with synthetic backing, cork-linoleum and cork underlayments.
It is suitable for use onto subfloors of concrete, sand/cement screed, anhydrite screeds, smoothing underlayments, flooring grade plywood and timber.
For interior use only.
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. 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
Stir well before use. Apply an even coat over the whole area to be covered using a suitable notched trowel. Avoid puddle formation.
Consumption:
- Foam-backed textile floorcoverings: 250-300 g/m² (notched trowel N°1 or A2)
- 2-4 mm thick linoleum and floorcoverings with a rough underside: 350-400 g/m² (notched trowel N°2 or B1)
To ensure good transfer of the adhesive to the underside of the floor covering observe an appropriate open time (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.
EXCEPTION: when installing linoleum, lay it immediately whilst the adhesive is still wet (no open time required).
Use a rubbing block and/or roller to expel trapped air and to ensure good transfer of the adhesive. After 30-40 minutes, repeat. Weight down with sand bags (the joins) if necessary.
Do not weld the joins until the adhesive has had sufficient time to develop a good bond, normally 24 hours after installation.
REMARKS
- Optimum material temperature should be + 18°C
- During installation the subfloor temperature must be above + 10°C and relative humidity must not exceed 75%, optimum room temperature + 18°C, if possible
- Underfloor heating systems must comply with current building regulations. In all cases drying time must be respected. Turn off the heating 48 hours before starting the work. The heating should be turned up to its operating temperatures gradually, in stages over 48 hours after laying the floor covering. Do not apply when underfloor heating is in operation.
- Residual moisture content of the subfloors must not exceed 3%.
Cleaning
Tools should be cleaned with warm water, preferably whilst the adhesive is still wet.
