Definitions
Open timeTime between the moment the adhesive was applied and the moment it has no more tack (end of possible laying the covering)
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
Working timeTime between end of waiting time and moment when the application is no longer possible

Uses

EPONAL PU 456 is a 2-component polyurethane adhesive for bonding industrial PVC and rubber (collective kitchens, sports floor coverings, etc.), linoleum in sheet and tile, carpet floor coverings, synthetic grass, outdoor-, sports- flooring, unfinished and factory pre-finished parquet flooring (all wood species).

Recommended by main manufacturers.

It is suitable for use onto subfloors of concrete, sand/cement screed, anhydrite screeds, smoothing underlayments, existing floor tiles, flooring grade plywood and timber.

For interior and exterior use.

Benefits

Exceptional mechanical properties (high bond strength)
Moisture-resistant (suitable for use in wet areas: collective kitchens)
Excellent resistance to weathering (can be applied outdoors)
Heat-resistant: up to 120°C
Easy to apply
Wet-bond (no open time needed)
Water-free adhesive (no stress on water-sensitive floor coverings like linoleum or parquet)
Suitable for a wide range of substrates, coverings, materials and uses
Suitable for underfloor heating or cooling system

Safety:

IMPORTANT: before embarking on any work involving EPONAL PU 456 the separate Product Safety Data Sheet must be studied carefully by those carrying out the work. Prevent skin and eye contact. Prevent spillages. Do not breathe vapours. The use of Bostik barrier cream DERMOSAFE or protective gloves is recommended. After contact with skin, wash immediately with plenty of water.

Shelf life:

Up to 12 months in the original unopened container stored between +10°C and +30°C.

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 336 Moisture Vapour Barrier coating.

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

APPLICATION

Mix thoroughly the 2 components together using an electric drill and mixing paddle until a uniform non-marbled yellow/pale brown colour is achieved. Mixer speed should not exceed 200-300 rpm.

Because of exothermic mixing reaction, the short pot life (approx. 45 minute at 20°C) is drastically reduced at higher temperatures.

Apply an even coat over the whole area of a subfloor using a suitable notched trowel (depending on porosity and roughness of the substrate).

Type of floor covering	Notched trowel	Consumption
Technical PVC	N°A5	300 g/m²
Smooth, polished underside	N°2	400-500 g/m²
Rough underside	N°3	600-700 g/m²
Rubber floor coverings with a structured underside and parquet	N°4	800-900 g/m²

No open time needed, good initial bond strength is further reinforced during curing. Install the floor covering immediately into the wet adhesive, ensuring full adhesive transfer. Use a rubbing block and/or roller to expel trapped air and ensure good transfer of the adhesive. After 30 minutes, repeat.

Rigid and distorted floor coverings must be rolled and weighted until adhesive has fully cured. Setting times depend on temperature, quantity of mixed adhesive (the more the quantity, the faster the adhesive cures and sets).

Lay the floor covering according to the manufacturers’ recommendations.

REMARKS

- Wet conditions during installation may lead to foam formation on the surface of the adhesive film.

- For collective kitchens: strictly follow floor covering manufacturers’ recommendations

- At low temperatures adhesive thickens, bonding reaction slows down or may stop.

- Tightly close all containers after use.

Cleaning

Tools and spillages should be cleaned with a solvent (such as MEK-Methyl Ethyl Ketone), preferably whilst the adhesive is still wet.
