Application guidelines
Summary from the data sheet — follow the PDF on site.
Application
Note: The following is a typical application description. In case of other jobsite parameters, please contact our technical department.
Spread the mixture with a spatula, rake or toothed trowel. and immediately vent and level with a spiked roller.
An anti-slip surface is obtained by fully broadcasting it with the desired type of granulate. (4 to 5 kg/m²)
Processing time of POLYAC® 55 is 10 to 15 minutes.
Preliminary analyses
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® 51 must be applied a dry surface. Moisture content in the substrate: ≤ 5% moisture.
- Exception: ≤ 10% moisture if the primer POLYAC® 18 are used.
- 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.
Required tools
- Mixer with spindle (min. 300 rpm).
- Spatula, rake or toothed trowel.
- Spiked roller.
- Masking tape.
Preparation of the substrate
It is not necessary to place a primer on existing POLYAC® systems before applying POLYAC® 55.
POLYAC® 55 is always applied on a suitable primer depending on the type of substrate.
- POLYAC® 12: Dry, form-retaining, mineral substrates.
- POLYAC® 14: Moving or less form-retaining mineral substrates, asphalt or bituminous membranes.
- POLYAC® 15: Metal.
- POLYAC® 18: Damp, form-retaining, mineral substrates.
(Always consult the POLYAC® primers technical data sheets) Before applying the primer.
- Tears, cracks, joints and other elements showing water leaks must be made fully water and leak proof.
- The surface must be mechanically pre-treated. This can be achieved by removing the dust by bullet- or sandblasting or by grinding the surface.
- Tiles are to be degreased well and grinded with a diamond blade. These treatments ensure that an open texture surface is obtained, to remove the cement skin from concrete and old remnants of coatings and adhesives.
- High pressure water jetting is possible but then the surface must dry sufficiently before applying the primer. (Moisture content in the substrate:
- ≤ 5% moisture. Exception: ≤ 10% moisture if the primer POLYAC® 18 is used.
- Always apply the products on a clean surface, free from adhesion reducing materials such as dirt, oil, grease, old coatings or surface treatments, …
- 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.
- The surface must be mechanically pre-treated. this can be achieved by removing the dust by bullet- or sandblasting or by grinding the surface.
- The degree of roughness for metal surfaces is SA 21/2. Remove rust by sandblasting. The surface must be dry and free of impurities such as grease, oil or dust.
- Galvanized steel is thoroughly cleaned in advance with water and soap or sandblasted. Degrease metal surfaces immediately after the mechanical preparation with SOLVENT MEK. After the SOLVENT MEK has fully evaporated, immediately apply a layer of POLYAC® 15 to prevent the steel from re-oxidizing.
Preparation of the product
Mix POLYAC® 55 well before use. Paraffin can separate during storage.
Dispense an amount of resin that can be processed within 15 minutes.
If a different colour is desired than the standard colour, you can now add 5% pigment powder (by weight of the resin part) to the resin and mix it well until a homogeneous mass is achieved.
The amount of aggregates is determined by the layer thickness, the climatic conditions and the application.

Application conditions
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.
