SikaBond®-201 Pressure Sensitive Adhesive

1-component Acrylic Dispersion

SikaBond®-201 Pressure Sensitive Adhesivehas a shelf life of 12 months from the date of production, if it is stored properly in undamaged, original, sealed packaging, and if the storage conditions are met.

SikaBond®-201 Pressure Sensitive Adhesive shall be stored in dry conditions, protected from direct sunlight and at temperatures between +5 °C and +25 °C.

+5 °C to +35 °C

+15 °C to +35 °C

40% to 60%

During laying and until SikaBond®-201 Pressure Sensitive Adhesive has fully cured, the substrate and ambient temperatures shall be between +15 °C and +35 °C. Where underfloor heating units are installed, the heating units shall be turned on prior to laying the floor covering for a minimum of 7 days to ensure that the moisture condition of the heated subfloor will permit successful laying of the coverings. Heating units shall be turned off 48 hours prior to the commencement of installation. The heating units shall not be turned on again until 48 hours after the laying is completed.

Moisture content requirement:
85% RH (in-situ probe method: ASTM F2170) or 15 g/m2 per 24 hrs (moisture vapour emission rate surface test ASTM F1869) prior to installation.
pH requirement:
The pH / alkalinity of the concrete must not be higher than 10.
Note: AS2455:1 should be followed in conjunction with the guideline of the soft floor manufacturer.

For the application of SikaBond®-201 Pressure Sensitive Adhesive all standard construction guidelines and relevant valid data sheets apply.

• The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles. Paint, cement laitance, prior adhesives, floorcoverings and other poorly adhering contaminants must be removed.

• All surfaces must be prepared in accordance to the current Australian Standards 2455:1 Textile floor covering – installation practice.

• Prime highly absorbent substrate with Sikafloor® -01 Primer prior to application of SikaBond®-201 Pressure Sensitive Adhesive.
• Defective subfloors shall be treated by taking appropriate measures e.g. grinding, milling, vacuuming, priming or self-levelling.
• Mastic asphalt and other non-absorbent subfloors as well as rubber floor coverings may require specific self-levelling compound layer thicknesses. For appropriate layer thicknesses refer to the relevant valid data sheets.
• Concrete and/or cement screeds must be ground and thoroughly cleaned with an industrial vacuum.
• When installing floor covering with underfloor heating, existing measuring points have to be checked regarding the moisture content of the subfloor.

Clean excess adhesive immediately using a lightly damp cloth. Clean tools immediately after use with warm soapy water. Dried adhesive may be softened using a Sika cleaner such as Sika® Colma Cleaner

IMPORTANT: Do not use solvent cleaner directly on finish floorcovering, as the solvent cleaner can potentially cause damage to the surface.
