SURFACE PREPARATION:
- To be in accordance with the current Australian Standard “Floor
Coverings – 1884-2012 Resilient Sheet & Tiles – Laying & Maintenance Practices” or
Australian Standard 2455.2.2019 “Textile Floor Coverings – Installation Practice”. - All surfaces to be bonded shall be absorbent, dry, smooth, sound and
clean. Subfloors must also be free of wax, grease, paint, previously used adhesive,
polish, PVC based membranes, curing compounds, hydrostatic pressure and any other
impurities that may affect adhesion. - The minimum subfloor temperature before commencing surface preparation
and adhesive application is 10°C. - Test all concrete substrate flooring for moisture content, according to
the current Australian Standards prior to priming or the Installation of any
floorcoverings - If mechanical preparation is required prepare the floor using
recommended preparation methods such as shot blasting, diamond grinding, to provide
a roughened, clean, sound, and open porous surface. - Thoroughly vacuum loose material and dust.
- It is recommended that highly absorbent concrete subfloors be primed
with Roberts R400 floor and wall primer prior to the application of adhesive. - Indentations and uneven concrete subfloors should be treated with the
Roberts range of levelling compound and be in accordance with manufacturer’s
recommendations.
APPLICATION:
- Spread adhesive with the recommended notched trowel.
- Bonding Carpet Tiles to subfloor when laid in a releasable mode we
recommend the use of a long nap roller with a pile height of no less than 10mm. - Alternatively a 1.6mm x 1.6mm “V1” notched trowel is also recommended.
- Roberts 444 Pressure Sensitive Adhesive is used in dry mode, allow the
adhesive to dry and become clear, this will limit the transfer of the adhesive to
the back of the carpet tiles therefore enabling them to be relayed or repositioned
with a clean backing. - A stronger bond can be achieved by laying the material into the adhesive
film just prior to it drying completely, this will cause some transfer onto the
back of the material. - Complete installation according to Floorcoverings manufacturer’s
instructions, ensuring the installation is rolled in both directions
With the recommended roller weight.
COVERAGE:
- Coverage when applying adhesive with a Long Nap Roller Pile height no
less than 10mm can achieve an approximate spread rate of 8-10 square metres per
litre. - “V1” 1.6mm x 1.6mm notched trowel will achieve approximately up to 5
square metres per litre. - Spread rates may vary depending on the condition and substrate
absorbency.
SETTING TIMES:
- Roberts 444 Pressure Sensitive Adhesive will tack up and turn clear
after approximately 30 minutes to 1 hour at 20°C. - Times may vary depending on substrate absorbency, temperature and
humidity.
CLEAN UP:
