Polyac 61 — Tough-flexible, liquid-tight top layer for Polyac floor and membrane systems

Note: The following is a typical application description. In case of other jobsite parameters, please contact our technical department.

POLYAC® 61 is evenly distributed with a rubber squeegee or a short-haired paint roller. Apply sufficient POLYAC® 61 to create a tight top layer. Processing time of POLYAC® 61 is 10 to 15 minutes. Do not disturb the paraffin layer that occurs during curing. After one hour (at 20°C) a second layer of POLYAC® 61 can be applied if necessary.

POLYAC® 61 top layer is only placed on another POLYAC® system.

Before starting the substrate preparation and applying the products, it is important to test various parameters in order to achieve a good and sustainable result.

• Compressive strength of the substrate: min. 25 N/mm2
• Tensile strength of the substrate: min. 1,5 N/mm²

• POLYAC® 61 must be applied a dry surface. Moisture content in the substrate: ≤ 5% moisture.
• Conditions during the application and curing: see “Application conditions” further described in this technical data sheet.
• Technically studied dilatation joints must be provided. These are resumed in the synthetic resin system to be installed.
• The flatness of the surface must be consistent with the desired requirements. Should this not be the case, correct measures must be taken to fill in or smooth out the unevenness with products that are complementary to the substrate and to the synthetic resin system to be installed.
• Shrink joints and passive cracks can be coated. This on condition that they are not used as dilatation joints or if they do not follow other movements of the structure and the substrate and that they are flattened with products that are complementary to the substrate and to the synthetic resin system to be installed.

• Mixer with spindle (min. 300 rpm)
• Rubber squeegee

Brush or pain roller suitable for synthetic resin-based products.

Masking tape.

POLYAC® 61 top layer is only placed on another already cured POLYAC® system. Always apply the products on a clean substrate, free from adhesion-reducing materials such as dirt, oil, grease, etc. High pressure water jetting is possible but the surface must dry sufficiently (moisture content in the substrate: ≤ 5% moisture) before applying the primer.

Cracks, joints and other parts that show water leaks must first be made completely water-tight and leak-proof. The parts of the surfaces to be coated that do not meet the requirements as described above (compressive strength, tensile strength, parts that are not well connected, …) must be treated or removed and repaired according to a correct method and with products that are complementary to the substrate and the synthetic resin system to be installed.

Remove any loose parts by brushing properly and remove dust with an industrial vacuum cleaner.

Mix POLYAC® 61 well before use. Paraffin can separate during storage.

Dispense an amount of resin that can be processed within 15 minutes.

For colouring POLYAC® 61 8% pigment powder is added and homogeneously mixed before adding the POLYAC® CATALYST. Add 1 to 5% curing powder. POLYAC® CATALYST must be ordered separately.

Mix until the powder is completely dissolved.

Always work with clean mixing containers and application material.

Conditions during the application and curing of the products.

The recommended processing temperature for substrate, environment, material and products is between +5°C and +35°C. For temperatures lower than +5°C please contact RESIPLAST NV.

Relative humidity: Max. 85%

Dew point: The temperature of the substrate and of the not fully cured product must be at least 3°C higher than the dew point. Avoid condensation on the surface from the moment that the preparations start until the complete curing of the products. Ensure adequate ventilation and a low relative humidity during curing.

Clean the used tools with SOLVENT MEK or ethyl acetate before the curing of POLYAC® 61. Cured products residues must be removed mechanically.

For the cleaning and maintenance of the installed synthetic resin system, please refer to the information leaflets:

Cleaning and maintenance of synthetic resin floor systems – INDUSTRY TOUGH – FLEXIBLE PMMA TOP LAYER FOR POLYAC® SYSTEMS

POLYAC® 61

Cleaning and maintenance of synthetic resin floor systems – PUBLIC AND PRIVATE BUILDINGS.

• Cleaning solvent for tools: SOLVENT MEK or ethyl acetate

• Pigment powder

To obtain a better coverage a fine filler can be added to POLYAC® 61.

For more information please contact RESIPLAST NV.

Rather smooth surface: 0.35 kg/m²

Consumption on an anti-slip surface broadcasted with colour quartz grain 0,8 – 1,2 mm. grain size; 0.6 kg/m² With a higher roughness or if one wants to level out the roughness, consumption increases up to over 0,8 kg/m².

To be ordered separately:

Store POLYAC® products in a dry, well-ventilated storage area between +5 and +35°C. Shelf life: 12 months after production date.

In case of doubt, please contact RESIPLAST NV and state the batch number on the packaging. Do not discharge into groundwater, surface water of sewers. Dispose of contaminated packaging and residues in accordance with the applicable legal requirements.

Carefully read the safety data sheets before using POLYAC® products. A characteristic odour arises during processing. Ensure adequate ventilation, keep away from sources of ignition and do not smoke. Avoid skin contact. Eye irritation and/or hypersensitivity may occur with severe vapour concentration, inhalation and/or skin contact. Do not store food (food, drinks) in the same workspace. Always wear personal safety equipment in accordance with the applicable local guidelines and legislation. Gloves and safety glasses are mandatory.

All values on this technical sheet are average values that result from tests carried out under laboratory conditions (20°C and 50% RH). Values that are measured on the construction site may show a slight deviation since the environmental conditions, the application, and the way of processing our products are beyond our control. Do not add any products other than those indicated on the technical documentation.
