DESCRIPTION

A solvent free modified acrylic emulsion formulated to provide a permanently tacky film for the removable fixing of "loose lay" carpet tiles. This enables the tiles to be easily lifted and replaced when required. The adhesive in non staining, resistant to plasticiser migration and may be applied by either roller or brush.

USES

• Bond It CTT is a recommend for installing carpet tiles with the following backing: PVC, PVC/Glass Fibre, Bitumen/Felt or non woven fabric, APP and other polymer backings including polyurethane, Hessian.
• It may be applied to most common substrates, including concrete, cementitious screeds, chipboard** hardboard, plywood and smoothing compounds and metal access floor panels. It may be used over existing well bonded resilient floor coverings provided they are thoroughly cleaned of any wax, polish or other contaminants. It is suitable for use where there are underfloor heating systems. However, heating should be switched off at least 48 hours before and after the installation of the floor covering.
• ** Please note that some chipboard products have been treated preservatives and for fire proofing or moisture proofing and may be unsuitable for adhesion. Please check boards and contact technical services.

APPLICATION INFORMATION

• Apply an even coating of CTT with either a roller or brush and allow to dry to a clear tacky film (approx 30 - 40 minutes) before placing the tiles. The time will vary due to room and floor temperatures, porosity of sub-floor and thickness of adhesive layer. Good airflow through the rooms will shorten waiting time. When laying on metal access floor panels care must be taken to ensure that the adhesive does not flow between panel joints.
• Please Note: Placing tiles before the adhesive has dried to a clear film may result in permanent bonding.

SUBSTRATE PREPARATION

• All phases of the installation should comply with the latest editions of the following standards: -
• BS CP 102 Code of Practice - for protection of building against water from the ground.
• BS 5325 Code of Practice - for installation of textile floor coverings.
• BS 8203 Code of Practice - for installation of resilient floor coverings.
• Sub-Floor: Ensure the sub-floor is clean, sound, dry and free from contaminants that may hinder adhesion, including surface hardeners and additives. It should have an effective damp-proof membrane and be tested in accordance with British Standards, using a properly calibrated and insulated hygrometer. A reading of 75% RH or less indicates the sub-floor is suitably dry
• Mechanically remove any surface treatments or "friable" areas to expose a sound concrete base. Repair any deep indentations in the sub-floor with a suitable patch repair product. Where floors require smoothing apply a suitable smoothing compound at a minimum of 3mm thickness. Surfaces should be thoroughly cleaned (preferable vacuumed). Existing resilient floor coverings must firmly bonded to a sound sub-floor and all contaminants (wax, polish etc) must be removed.
• Priming: Prime boards and other porous surfaces with a Bond It PVA (diluted 1:4 with clean water) or other recommended primers, and allowed to dry. This is imperative with hardboard, chipboard and plywood. Ensure the floor covering manufacturer recommends the floor covering for use with the particular substrate.
