IMPORTANT
Exposure to moist or wet heat
Sikafloor® broadcast systems with a minimum thickness of ~3–4 mm, that use this product, can resist short-term moist or wet heat of up to +80 °C, if the exposure is only temporary (less than 1 hour). However, during exposure to moist or wet heat, do not also subject the Sikafloor® broadcast system to chemical and/or mechanical strain, as it may cause damage to the system.
Application
Mixing Ratio
Part A : Part C : Part D = 12.5 : 1 : 25 (by weight)
The amount of Hardener required depends on the substrate temperature:

| 0 °C | 6 % |
| +10 °C | 4 % |
| +20 °C | 2 % |
| +30 °C | 1 % |
Note: For ease of handling, units may be split into smaller amounts. Make sure to follow the mixing ratios as described in the Application Information. Always weigh out each part before mixing it.

Note: Consumption data is theoretical and does not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.
APPLICATION INSTRUCTIONS
IMPORTANT
Strictly follow installation procedures
Strictly follow installation procedures as defined in Method Statements, application manuals and working instructions which must always be adjusted to the actual site conditions.
EQUIPMENT
APPLICATION EQUIPMENT
-
Trowels, including serrated
-
Spiked roller
MIXING EQUIPMENT
- Electirc double paddle mixer (>700 W, 300 to 400 rpm)
SUBSTRATE QUALITY
SUBSTRATE CONDITION
Cementitious substrates (concrete / screed) 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 all contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.
MIXING
SELF-SMOOTHING WEARING LAYER MIXING PROCEDURE
- Mix Part A (resin) for ~30 seconds.
- Add the required filler.
- 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.
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/exhausting of 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
Pin holes
If the Product is applied on porous substrates during rising temperatures, pin holes may form from rising air.
- Apply the Product during falling temperatures.
REINFORCED SELF-SMOOTHING WEARING LAYER APPLICATION
- Pour the mixed Product onto the substrate. Note: The consumption is specified in 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: A seamless finish can be achieved if a "wet" edge is maintained during application. - Roll out the reinforcement (Sika® Reemat Premium) onto the wet resin. 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.
CLEANING OF TOOLS
Clean all tools and application equipment with Sika® Thinner C immediately after use. Hardened material can only be removed mechanically.
