FORTIS COAT 824 SL is a self-levelling solvent-free two-pack epoxy floor coating designed for build coats from 5mm to 40 mm. FORTIS COAT 824 SL is available in clear for metallic flooring and in colours. Refer to the Colour Chart.
FORTIS COAT 824 SL is self-levelling epoxy mortar coat. As a 2 Pack, it will allow up to 10mm build. In contrast, the 3 pack system with filler will build up to 30mm. Both provide a seamless epoxy base suitable for the remediation of errored concrete flooring. FORTIS COAT 824 SL clear is the perfect choice for metallic flooring able to provide 5-10mm of the build.
FORTIS COAT 823 SL is ideal for heavy industrial flooring, warehousing, factories, printing facilities, food processing plants, and recycling plants, and is also suitable for domestic and retail applications.

Application of FORTIS COAT 824 SL self-levelling epoxy flooring should take place after priming but within 24 hours.
Mix Components A (resin) and B (hardener) in the predetermined mixing proportions provided. Stir the for approx. 3 minutes with a low-revolution (300 rpm) mixer. It is important that stirring reaches the wall and bottom of the container as well, to achieve uniform dispersion of the hardener.
If 3 Component process add quartz sand with particle-size 0-0,4 mm gradually into the mixture under continuous stirring, in proportion 1:2 by weight (epoxy resin (A+B): sand) to obtain a uniform epoxy mortar.
Spread FORTIS COAT 824 SL with a notched trowel at a thickness of 2-3mm. To remove any air trapped in the self-levelling layer, the surface should be gone over with a special spiked roller. This inhibits the formation of bubbles.
Spread FORTIS COAT 824 SL with a notched trowel at a thickness of 2-3mm. Whilst the coating is still-fresh sprinkle with quartz sand, grade 0,1-0,4 mm or 0,4-0,8 mm, depending on the desired slip resistance at a rate of 3 kg/m2. Remove excess loose sand once FORTIS COAT 824 SL has hardened. Seal with a thin coat of 824SL in the desired colour.
The surface on which the epoxy coating is going to be applied must be dry (<4% moisture), stable, free of dust, loose particles, grease. The substrate must be properly prepared. Refer to Technical Note #4 - Surface Preparation, to open the pores to allow penetration of the primer. This will ensure better anchoring and bonding of the epoxy coating. Subsequently, the surface should be carefully cleaned with a high suction vacuum cleaner. The properly prepared surface (as described above) should then be primed with Fortis 820 Prime. Once the primer is dry, any imperfections in the surface (cracks, holes) should be filled and repaired with Fortis 820 Prime (A+B), mixed with grade 0-0,4 mm quartz sand, in the ratio of 1:2 to 1:3 by weight.
