Consumption
| System | Product | Consumption |
| Levelling(optional): | Sikafloor®-Level | ~1.7kg/mm/m2 |
| Primer: | 1-2 x Sikafloor®-156/-161L | 0.3-0.5kg/m2 |
| Anti-cracking layer: | Sikafloor®-325SL | 1-1.4kg/m2 |
| Terrazzo mortar: | Sikafloor® Terrazzo + Aggregate | ~2.5kg/mm/m2 |
| Sealer: | Sikafloor®-169 CN | ~0.2kg/m2 |
| Curing agent(optional): | Sikafloor®-Proseal Finish | 0.1-0.2kg/m2 |
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level and wastage
etc. Lower consumption can cause gloss differences and irregular surface structure,The actual addition of aggregate should be depending on temperature and thickness on site.
MIXING
Precondition material for at least 24 hours to between 18° to 26°C before use to assist application and achieve the best results.
Pre-stir thoroughly each component of Sikafloor® Terrazzo to ensure all solids and pigments are evenly distributed and even colour or clarity and consistency are achieved within each component.
Where supply format permits, empty Component B into Component A. Alternatively and in the correct ratio by quantity Component A: Component B, empty material into a suitably sized and clean mixing vessel and thoroughly mix using a low-speed drill (300 - 450 rpm) and Exomixer-type mixing-paddle (recommended model). To minimize entrapping air, ensure mixing paddle is kept in the material. To the 25kg mixed unit, slowly add marble dust filler and selected aggregate chips. During the mixing operation, scrape down the sides and bottom of the pail with a flat or straight-edge trowel at least once to ensure thorough mixing. When completely mixed. Sikafloor® Terrazzo should be uniform in colour, aggregate chips should be thoroughly wetted out and the consistency should be homogeneous before use.
Mix only the quantity you can use within its pot life.
APPLICATION
Sikafloor® Terrazzo epoxy matrix can be combined with a wide range of fine and coarse mineral aggregate chips (marble or granite), coloured or recycled glass, mirror particles, plastic and non-corrosive metal fragments. these aggregates can all significantly affect the application properties, coverage rate achieved and final appearance.The applicator’s preferred installation technique (slurry and broadcast or traditional screed and trowel) methodology will determine an individual contractor’s preference for thixotropy. The addition rate of marble dust is variable as it absorbs resin, thickening the matrix, allowing the applicator to make adjustments to meet their specific application technique or site environmental conditions. Due to the wide variety of aggregate chips used to create an unlimited design pallet, it is impractical to produce a single specific mix design that will meet the needs of all parties involved.
The Sikafloor® Terrazzo mix design provided below is a starting point that requires further refinement. It is the responsibility of the terrazzo applicator to conduct additional project specific mix design mock-ups, to finalize adjustments to the mix to achieve an acceptable final appearance, establish production rates, predict pinhole frequency and finalize aggregate and epoxy consumption.
Alternative aggregate chips types, i.e. glass, plastic and non-corrosive metal can be incorporated into the mix design, consult Sika China Technical Services Department for advice.
Pour mixture of Sikafloor® Terrazzo onto the floor, immediately spread and compact the mortar to the desired thickness using a 75 mm (3 in) wide steel trowel. Take care to spread newly mixed materials across the transition of previous applied mixes before the surface begins to set. Allow the applied terrazzo to cure for 18 hours at 23°C before initiating the grinding operation.
CLEANING OF TOOLS
Clean all tools and application equipment with Thinner C immediately after use.
Hardened and/or cured material can only be removed mechanically.
