Remarks	:	Technical information and safety data sheets of any laying materials and floor coverings used must be observed! Allow floorings to air condition in the rooms before laying. The coverings must be relaxed and laid flat. During the setting phase, the direct influence of heat/solar radiation, dynamic and point loads must be avoided. Do not weld the coverings until the following day at the earliest. In order to minimise residual impressions as far as possible, resilient floor coverings should always be placed in the wet adhesive bed and immediately rubbed down well to completely crush the adhesive ridges. If the insertion time is exceeded, during which the adhesive grooves can still be completely squashed, standing grooves remain which can mark the top side of thin coverings or be squashed under point loads. This leads to visible deformations in the floor covering structure. The work progress is to be set up in such a way that a flash-off time, at wetting of the reverse side of the flooring is guaranteed, is not exceeded. With regard to such markings any claims arising therefrom are excluded. In the case of textile coverings, attention must be paid to the dimensional stability when exposed to moisture (shrinkage). When bonding textile coverings without fillers, a flash-off time of approx. 20 minutes must be observed to prevent the still wet adhesive from "sticking" into the back of the covering. EMICODE, further information at www.emicode.com. Wear protective gloves / eye protection.

* The mentioned values have been established in our laboratory and must be considered as guidelines in view of possible variations in climatic circumstances, subfloor compositions and layer thickness.

Consumption:
approx 250 - 300 g/m², depending on the condition of the subfloor.

Substrate:

The substrate must be pressure- and tension-resistant, permanently dry, free of cracks and dust, even and free of layers that reduce adhesion.
Adhesion-reducing layers, old material residues must be removed by suitable mechanical measures in accordance with the specifications of DIN 18365.
For levelling the substrate use recommended Eurocol levelling compounds/primers.
The installation materials to be used must be suitable for the substrate and the intended use.

User manual:

Before use, temper the product according to the processing conditions.
Stir before use!
Depending on the type of flooring, apply the adhesive with a notched trowel to the subfloor over the entire surface and evenly without adhesive nests. The back of the flooring must be completely wetted with adhesive in scored format. Worn-out spatulas need to be replaced in time to guarantee the minimum adhesive consumption.
Coverings must be laid in the adhesive bed which is still wet.
The necessary flash-off time depends on the amount of adhesive (toothed strip), temperature, humidity and the absorbency of the subfloor.
When finger-testing, the adhesive must have a soft centre, must be tacky, pull threads, but must not smear.
Depending on the room climate and the absorbency of the substrate, the air-conditioned covering should be pushed into the adhesive bed immediately or after the flash-off time specified in the technical data, rubbed in and rolled on. Air pockets under the covering must be avoided or removed immediately.
Head ends and non-flat covering edges must always be rolled in.
If necessary, rub or roll the top ends, seams or other hollow areas again approx. 15 minutes after installation.

Special instructions:

Wet/one-side gluing:

If the substrate is absorbent, allow the adhesive to flash off for approx. 10 - 15 minutes (skin formation) and lay the covering in the still relatively damp adhesive bed and rub/roll it in.
Within the working time of approx. 30 minutes, but as a wet adhesive, lay the adhesive, rub down well immediately and roll the surface vigorously.

Pressure sensitive adhesive

In the case of non-absorbent substrates and impermeable coverings, the adhesive must flash off completely.
Flash-off time approx. 30 - 90 minutes depending on the room climate conditions.

Contact bonding

Apply the adhesive to the substrate and the back of the covering and allow to dry in the same way as the pressure-sensitive adhesive.
Within the contact bonding time of approx. 90 minutes, lay the covering and rub down well. Corrections are no longer possible!

The adhesive can be reactivated with heat within a few days. To do this, heat the covering and substrate to approx. 70 - 80°C (welding device) and carry out the bonding process in the same way as for contact bonding.

Adhesive Roll - System

The adhesive, applied with a toothed strip, is immediately rolled out with Eurocol Microfibre Roller. This shortens the flash-off time and the tendency of coverings to indentations under early loading, as well as the marking of Scoring and the tendency to re-soiling

Working conditions:

At least 15 °C floor temperature,

at least 18°C material and room temperature,

35-75% relative humidity, recommended <65%.
