0.0 (0)
Sikafloor®-515 is a clear, two-component, high-solids, low-viscosity, high-strength, polyaspartic resin system with exceptional resistance to tire marking; making it ideal as a garage floor finish. Sikafloor®-515 is designed to be installed as a clear topcoat over a quartz or flake broadcast system where a low VOC, quick cure, flexible, and UV resistance finish coat is necessary. Sikafloor 515 is available only in clear.

Coverage
Smooth Finish Coating:
Prime coat: 160 – 200 ft2 / US gal. (3.9 – 4.9 m2 / L ) at 8 – 10 mil (0.20 – 0.25 mm) wet film thickness (w.f.t.)
Wear coat: 105 – 135 ft2 / US gal. ( 2.6 – 3.3 m2 / L) at 12 – 15 mil (0.30 – 0.38 mm) wet film thickness (w.f.t.)
Note: These figures do not allow for surface porosity, profile or wastage.
MIXING
Mixing Ratio - 3:2 by volume.
For bulk packaging, when not mixing full units, each component must be pre-mixed separately to ensure product uniformity.
Clear Resin
Premix each Component separately. Empty Component B (Hardener) in the correct mix ratio into Component A (Resin). Mix the combined components for at least 3 minutes using a low speed drill (300 - 450 rpm) and Exomixer or Jiffy type paddle suited to the volume of the mixing container to minimize entrapped air. Be careful not to introduce excessive air bubbles while mixing. Make sure the contents are completely mixed to avoid any weak or partially cured spots in the coating. During the mixing operation, scrape down the sides and bottom of the container with a flat or straight edge trowel at least once to ensure complete mixing.
APPLICATION
As a clear topcoat for a broadcast quartz or flake systems
Squeegee and back roll Sikafloor®-515 to provide a uniform coverage without ponding at a thickness of 10 – 15 mil (0.25 – 0.38 mm ) 107 – 160 ft2/US gal. (2.6 – 3.9 m2/L) . If required, repeat this procedure for a second coat.
As a stand-alone double broadcast quick cure decorative quartz and flake system
Step 1: Primer - Apply neat coat of Sikafloor®-515 on a prepared substrate as a primer using a squeegee and back roll to a uniform coverage without ponding at 8 – 10 mil (0.20 – 0.25 mm) 160 – 200 ft2/US gal. (3.9 – 4.9 m2/L).
Note: When using Sikafloor®-515 as primer extra precaution has to be taken on the substrate preparation and moisture content, see product limitations for further details.
Step 2: First Broadcast Application
Squeegee and back roll Sikafloor®-515 to provide a uniform coverage without ponding at a thickness of 10 – 15 mil ( 0.25 – 0.38 mm ) 107 – 160 ft2/US gal. (2.6 – 3.9 m2/L). Broadcast pre-blended decorative flakes or coloured quartz ggregates into the binder to saturation. Broadcast in a manner so that the flakes or coloured quartz aggregates fall vertically into the binder. Broadcast to rejection. Ensure that broadcast flakes / aggregates cover entire surface. Allow broadcast system to cure sufficiently to be able to resist foot traffic without damaging the surface. Remove excess flakes / aggregates from the surface by sweeping up and vacuuming, until surface is free of all loose particles and dust.
Step 3: Second Broadcast Application
Squeegee and back roll Sikafloor®-515 to provide a uniform coverage without ponding at a thickness of 10 – 15 mil (0.25 – 0.38 mm) 107 – 160 ft2/US gal. (2.6 – 3.9 m2/L). Broadcast pre-blended decorative flakes or coloured quartz aggregates into the binder to saturation. Broadcast in a manner so that aggregates fall vertically into the binder. Broadcast to rejection. Ensure that broadcast flakes / aggregates cover entire surface. Allow broadcast system to cure sufficiently to be able to resist foot traffic without damaging the surface. Remove excess flakes / aggregates from the surface by sweeping up and vacuuming, until surface is free of all loose particles and dust.
Step 4: Finish Coat
Squeegee and back roll Sikafloor®-515 to provide a uniform coverage without ponding at a thickness 10 – 15 mil (0.25 – 0.38 mm ) 107 – 160 ft2/US gal. (2.6 – 3.9 m2/L ). When required, repeat this procedure for a second coat.
Critical Recoat / Overcoat Time
It is important to apply subsequent coats of this and other products within 6 to 24 hours (under normal curing conditions). If this coating is allowed to cure longer than the 24 hours before subsequent recoats, light sanding, vacuum cleaning and solvent wiping will be necessary. The floor surface should be sanded / abraded to the effect that a uniform dullness is achieved. There should be no gloss present on the floor after vacuuming and before applying the next coat.
