Roberts R656 Pressure Sensitive 15 Litres Carpet Tile Adhesive

ROBERTS R656 Pressure Sensitive Adhesive is a solvent-free pressure sensitive adhesive formulated for installing PVC backed, fibre backed, cushion back carpet tiles and reinforced vinyl composition tiles. It is also highly recommended for installing laminated slab underlays used in Double-Bond carpet installation.

ROBERTS R656 can be applied to concrete substrates with moisture contents up to 95% Relative Humidity (moisture reducing) tested with the In-Situ Probe method and concrete substrates with pH readings of up to 12.0.

• Cushion Back Carpet Tiles
• Double bond underlays to substrate
• Carpet tiles to Double bond Underlays
• Reinforced Vinyl Composition (VCT) Tiles
• Vinyl Planks with an embossed backing system

Surface Preparation

Follow all current Australian Standards, including Australian Standard 2455.2.2019 "Textile Floor Coverings Installation Practice" & "Floor Coverings 1884-2021 Resilient Sheet & Tiles - Laying & Maintenance Practices". All surfaces to be bonded shall be absorbent, dry, smooth, sound, and clean.

Subfloors must 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.

ROBERTS R656 Pressure Sensitive Adhesive can be applied to concrete substrates with up to 95% moisture content. Relative Humidity is tested with the In-Situ Probe method as outlined in ASTM F2170.

ROBERTS R656 Pressure Sensitive Adhesive can be used on concrete substrates with pH readings up to 12.0.

Before applying adhesive, it is recommended that highly absorbent concrete subfloors be primed with ROBERTS R48 Universal Primer before using adhesive.

Application

For securing Double-Bond underlays to a substrate, applying the adhesive with a 1.6mm x 1.6mm "V1" notched trowel is recommended.

Bonding Carpet Tiles to subfloor when laid in a releasable mode, we recommend using 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.

For securing reinforced Vinyl Composition (VCT) Tiles, Vinyl Planks with an embossed backing system, Loose Lay Vinyl Planks and Cushion Back Carpet Tiles to a subfloor, a 1.6mm x 1.6mm "V1" notched trowel is recommended. Alternatively, if a stronger bond is required, a 2.4mm x 2.4mm "V2" notched trowel is also recommended.

Roberts 656 Universal Pressure Sensitive Adhesive is used in dry mode, allowing 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 before it completely dries.

Complete installation according to floor covering manufacturer's instructions, ensuring the installation is rolled in both directions with the recommended roller weight. Do not allow heavy traffic for 24 hours.
