While the Product is exposed to temperatures up to +80 °C, simultaneous mechanical or chemical strain may cause damage to the Product.
- Do not expose the Product to chemical or mechanical strain at elevated temperatures
Short-term, maximum 1 hour | +60 °C |
Short-term, maximum 48 hours | +50 °C |
Permanent | +40 °C |

EQUIPMENT
MIXING EQUIPMENT
Electric double-paddle mixer (> 700 W, 300 rpm to 400 rpm)
APPLICATION EQUIPMENT
Trowels, including serrated
Spiked roller
SUBSTRATE QUALITY
Cementitious substrates must be structurally sound and of sufficient compressive strength (minimum 25 MPa) with a minimum tensile strength of 1.5 MPa.
Substrates must be clean, dry and free of contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.
MIXING
SELF-SMOOTHING WEARING LAYER AND SCRATCH COAT MIXING PROCEDURE
- Mix Part A (resin) for ~30 seconds.
- Add the required filler.
- If required, add Part C (pigment) to the mixture while continuously mixing.
- IMPORTANT Do not mix excessively. Mix for a further 2 minutes until a uniform mix is achieved.
- Add Part B (hardener) to Part A.
- Mix for an additional minute.
- To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth and uniform mix.
- During the final mixing stage, scrape down the sides and bottom of the mixing container with a flat or straight edge trowel at least once to ensure complete mixing.
- IMPORTANT Do not mix excessively. Mix for a further 2 minutes until a uniform mix is achieved.
- To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth and uniform mix.
- During the final mixing stage, scrape down the sides and bottom of the mixing container with a flat or straight edge trowel at least once to ensure complete mixing.
APPLICATION
IMPORTANT
Protect from moisture
After application, protect the Product from damp, condensation and direct water contact for at least 1 hour.
IMPORTANT
Ventilation in confined spaces
Always ensure good ventilation when applying the Product in a confined space.
IMPORTANT
No application on rising moisture
Do not apply on substrates with rising moisture.
IMPORTANT
Ventilation for curing
For optimal curing, exchange the air at least seven times per hour. During application and curing, use a forced fresh air supply or exhaust fumes with appropriate equipment (explosion-proof).
IMPORTANT
Remove foodstuff from application area
Reactive acrylic resins exhibit a characteristic odour during application and before achieving full cure. Once fully cured, they are taint free. All unpackaged goods must be removed from the area of the works during application.
- Do not apply in the presence of foodstuffs.
- Isolate any and all foodstuffs, whether packaged or not, from the flooring works during the application process and until the products are fully cured.
IMPORTANT
Temporary heating
If temporary heating is required, do not use gas, oil, paraffin or other fossil fuel heaters. These produce large quantities of both carbon dioxide and water vapour, which may adversely affect the finish.
- For heating, use only explosion-proof electric powered warm air blower systems.
IMPORTANT
Pin holes caused by application during rising temperature
If the Product is applied on porous substrates during rising temperature, pin holes may form from rising air.
- Apply the Product during falling temperatures.
SELF-SMOOTHING BROADCAST WEARING LAYER APPLICATION
- Pour the mixed Product onto the substrate. For the consumption, refer to Application Information.
- Apply the Product evenly over the surface with a serrated trowel.
- Back-roll the surface in two directions at right angles with a spike roller. Note Maintain a "wet edge" during application to achieve a seamless finish.
- Broadcast the surface with aggregate, lightly at first, then to excess.Note The aggregate is dependant on the system build-up. Refer to the relevant System Data Sheet.
REINFORCED SELF-SMOOTHING WEARING LAYER APPLICATION
- Pour the mixed Product onto the substrate. For the consumption, refer to Application Information.
- Apply the Product evenly over the surface with a serrated trowel.
- Back-roll the surface in two directions at right angles with a spike roller. Note Maintain a "wet edge" during application to achieve a seamless finish.
- Roll out the reinforcement (Sika® Reemat Premium) onto the wet resin.IMPORTANT Allow a minimum 50 mm overlap on all joints of the reinforcement fleece.
- Press the reinforcement firmly into the wet resin with a short pile roller.
- To ensure full saturation of the reinforcement, apply wet on wet an encapsulation layer of the Product with a short pile roller.
SCRATCH COAT
- Pour the mixed Product onto the substrate. For the consumption, refer to Application Information.
- Apply the Product evenly over the surface with a trowel or a squeegee.
CLEANING OF TOOLS
Clean all tools and application equipment with Sika® Thinner C immediately after use. Hardened material can only be removed mechanically.
