PU 2K Long Working Time

Versatile parquet adhesive with long working time

Definitions
ImperviousCharacterisitc of a subfloor which porosity is very low. Adhesion on such substrates is usually more difficult and requires more attention and preparation.
PrimerLiquid or paste applied onto a substrate to obtain optimum bonding. It helps regulate the porosity of the substrate (reduce absorption, therefore adhesive usage), increase adhesion to non porous surfaces, improves application properties of later on applied adhesive
Tiling
Waiting timeTime between adhesive application and material bonding. It is required to wait to allow the adhesive to have enough adhesion power (tack) to receive the floor covering.
Working timeTime between end of waiting time and moment when the application is no longer possible

Uses

BOSTIK TARBICOL PU 2K long working time is a two-component polyurethane parquet adhesive suitable for securing all parquet types on absorbent and impervious substrates.

Suitable for direct bonding onto all types of substrates such as concrete screeds, cement/sand screeds, flooring grade plywood and particle board, metal decking, ceramic tiles, anhydrite screeds.

Suitable for securing:

- all wood species (including horn-beech, beech, birch and bamboo)

- strip parquet of all thickness and lengths, unfinished or factory-prefinished wood flooring

- mosaic parquet

- on-edge floorboards

- end-grain wood

Benefits

Long working time: about 80 minutes
Good moisture-resistace (e.g. bonding in wet areas)
High-temperature resistant : up to +80°C
Easy notched-trowel application
No waiting time required
Dry solids content: 100%, no primer required
Water-free, thus no damaging swelling effect on wood
Can be used on all types of subfloors
Suitable for underfloor heating and cooling systems
New packaging: 4 languages available - Bulgarian, Romanian, Russian and Ukranian

Safety:

IMPORTANT: before embarking on any work involving BOSTIK TARBICOL PU 2K Long Working Time, separate Product Safety Data Sheet must be studied carefully by those carrying out the work.

Shelf life:

Up to 18 months in the original unopened container stored between +10°C and +30°C. Frost/thaw stable down to -20°C. In case of product freezing, put the bucket into the heated room (+25°C) for at least 24-48 hours. Mix well before application.

Application

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.

When overlaying existing floor coverings ensure that they are firmly bonded and clean.

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.

All surfaces must incorporate adequate damp proofing, if not, they should be primed with Eponal 376 Moisture Vapour Barrier coating.

Always allow primers and self-levelling underlayment to dry thoroughly before applying the adhesive.

The adhesive is suitable for bonding onto all types of substrates such as concrete screeds, cement/sand screeds, flooring grade plywood* and OSB*, metal decking, ceramic tiles, anhydrite screeds*.

* ask for advice Bostik Technical Department

APPLICATION

Mix the two components using an electric drill and a mixing paddle (200-300 rpm) until a uniform non-marbled amber yellow colour is obtained. Do not mix at high speed : higher temperature will reduce the mixture pot life.

Apply the adhesive evenly onto the substrate using a notched trowel Pajaraito N°69 or B3 at a rate of 800-1400 g/m². No waiting time is necessary.

Distorted floorboards may need to be weighted and retained in position until full cure.

Cure rate depends on temperature and the quantity of the adhesive applied (the higher the quantity, the faster the adhesive heats up and cures).

All of the mixture should be applied immediately onto the subfloor in order to guarantee an optimum working time.

Beat the floorboards in order to ensure the best possible adhesive transfer to the underside of the parquet.

Allow a gap of at least 8 mm along the perimeter of the walls.

Gap dimensions: 0.15% of the largest dimensions of the area to be covered with flooring.

REMARKS

- Store the parquet in a dry place.

- Do not install parquet flooring if the relative humidity is over 65%.

- Underfloor heating systems must comply with current regulations. Turn off the heating 48 hours prior to installation. Wait for at least 1 week after laying the floor covering before gradually turning up the heating.

- Greasy wood species (e.g. teak) should be degreased with acetone before parquet installation.

CLEANING

Tools and spillages should be cleaned with acetone.
