Sikafloor®-511

ABRASION AND UV RESISTANT PIGMENTABLE POLYASPARTIC RESIN SYSTEM

Sikafloor®-511 is a two-component, solvent-free, high solids, low-viscosity, high strength, polyaspartic resin system. Sikafloor®-511 is designed to be available in clear that can used over a quartz or flake broadcast system where a low VOC, quick cure, flexible, UV resistance finish coat is necessary. Sikafloor®-511 is pigmentable with Sikafloor® SCO ColorAdditive to achieve a variety of colors.

Coverage

Prime coat:

160–266 ft2 / US gal (3.9–6.5 m2 / L) at 6–10 mils (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 mils (0.30–0.38 mm) wet film thickness (w.f.t.)
Application steps

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.  Apply up to 16 wet mils maximum.

  

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 any air 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.

  

Field Pigmented:
If color is desired, Sikafloor® SCO Additive is added to Component A at a rate of 1 quart per 2.5 mixed gal. (i.e. Components A+B) for all colors. Mix Component A and Sikafloor SCO Color Additive for 2 minutes or until a uniform color is achieved with a low speed drill (300–450 rpm) and Exomixer or Jiffy type paddle suited to the volume. Empty Component B (Hardener) in the correct mix ratio to Component A (Resin) and mix for additional 2 minutes. Be careful not to introduce any air 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 pigmented topcoat/sealer coat for smooth or broadcast finish
Squeegee and back roll Sikafloor®-511 to provide a uniform coverage without ponding at a thickness of 10–15 mils (160–107 ft2/gal). If required, repeat this procedure for a second coat.

   

As a clear topcoat for a broadcast quartz or flake system
Squeegee and back roll Sikafloor®-511 to provide uniform coverage without ponding at a thickness of 10–15 mils (160–107 ft2/gal). If required, repeat this procedure for a second coat.

    

As a stand alone double broadcast fast cure decorative quartz and flake system

Step 1: Primer - Apply a neat coat of Sikafloor®-511 on a prepared substrate as a primer using a squeegee and roller without ponding at 6–10 mils (160–266 ft2/gal).
Note: When using Sikafloor®-511 as primer extra precaution should be taken on the substrate preparation and moisture content. 

    

Step 2: First Broadcast Application

Squeegee and back roll Sikafloor®-511 to provide uniform coverage without ponding at a thickness of 10–15 mils (160–107 ft2/gal). Broadcast pre-blended decorative flakes or colored quartz aggregates into the binder to saturation. Broadcast in a manner so that the flakes or colored 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. Removal of excess flakes/aggregates is carried out by sweeping up the flakes/aggregates, followed by vacuuming, until surface is free of all loose particles and dust.

  

 

Step 3: Second Broadcast Application

Squeegee and back roll Sikafloor®-511 to provide a uniform coverage without ponding at a thickness of 10–15 mils (160–107 ft2/gal). Broadcast pre-blended decorative flakes or colored 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. Removal of excess flakes/aggregates is carried out by sweeping up the flakes/aggregates, followed by vacuuming, until surface is free of all loose particles and dust.

   

Step 4: Finish Coat

Squeegee and back roll Sikafloor®-511 to provide a uniform coverage without ponding at a thickness of 10–15 mils (160–107 ft2/gal). When required, repeat this procedure for a second coat.
