EQUIPMENT
MIXING EQUIPMENT
Electric double-paddle mixer (> 700 W, 300 to 400 rpm)
SUBSTRATE QUALITY
The surface must be clean, dry and free of contaminants such as dirt, oil, grease, coatings and surface treatments. All dust, loose and friable material must be removed from all surfaces using vacuum. Pull-off strength shall not be less than 1.5 N/mm2. If in doubt apply a test area first.
MIXING
- Mix Part A (resin) for ~30 seconds.
- Add Part B (hardener) to Part A.
- IMPORTANT Do not mix excessively. Mix Part A + B continuously for ~3 minutes until a uniform mix is achieved.
-
Gradually add either Sikafloor® Antislip Agent or glass beads to the mix.
Note: Refer to the aggregate addition table for the amount to add. - 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.
AGGREGATE ADDITION
Add the following amount of aggregate to the mixed Part A + B.
Aggregate | Addition |
Glass beads (90–150 µm or 200–300 µm) | 3 % to 10 % by weight |
Sikafloor® Antislip Agent | 2 % to 4 % by weight |
APPLICATION
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.
IMPORTANT
Protect from moisture
After application, protect the Product from damp, condensation and direct water contact for at least 7 days.
IMPORTANT
Damaged finish due to heating with fossil fuel heaters
Fossil fuel heaters powered by gas, oil or paraffin produce large quantities of both carbon dioxide and water vapour, which may adversely affect the finish.
- For temporary heating, use only electrically powered warm air blower systems. Do not use gas, oil, paraffin or other fossil fuel heaters.
IMPORTANT
Insufficient coating due to uneven or dirty substrates
Uneven or dirty substrates cannot be covered by thin seal coats.
- Clean the substrate and adjacent areas thoroughly prior to application.
SEAL COAT
-
Pour the mixed Product onto the surface.
Note: The consumption is specified in Application Information. - Apply the Product evenly over the surface with a micro fibre roller with a fibre length of ~10 mm.
-
Back roll the surface in two directions at right angles with a micro fibre roller.
Note: Maintain a "wet edge" during application for a seamless finish.
MULTI-COAT APPLICATION
The Product is typically applied as a single finish coat. When a multi-coat application is required, the surface must be prepared before the application of the subsequent coat.
- Roughen the surface by abrading using abrasive manual tools or mechanical equipment.
- Remove dust by industrial vacuuming equipment.
- IMPORTANT The prepared surface must be gloss free and uniformly dull in appearance. Solvent wipe the surface to remove all traces of dust and allow the solvent to evaporate.
CLEANING OF TOOLS
Clean all tools and application equipment with solvent immediately after use. Hardened or cured material can only be removed mechanically.
