Sikagard® Duroplast EE

Sikagard® Duroplast EE

High Performance Water Based Epoxy Blockfiller

Sikagard® Duroplast EE is a two part, high performance blockfiller designed to prime and fill small pores and reduce surface irregularities on properly prepared walls and ceilings. Designed to fill voids on porous surfaces and improve both the adhesion and appearance of high quality Sikagard® finishes that will be exposed to high levels of moisture in service.

  • Mix ratio, 1:1 by volume resin to hardener
  • Low odor and low VOC
  • Excellent bond and adhesion properties
  • Superior moisture resistance
  • Good chemical resistance
  • Good bridging and filling properties
  • Good hiding capabilities
  • Provides a more uniform even surface to coat
  • Fully compatible with Sikagard® finishes
  • Clean-up with water

Usage

  • Interior applications
  • On wall and ceiling constructed of concrete block, masonry, poured or pre-cast concrete.
  • To provide superior bonding properties needed to support two part epoxy and urethane finish coats in high abuse installation
  • To fill and seal walls and ceilings with variable absorption which might excessively absorb coatings
  • Wet and dry process areas subject to repeated cleaning such as; food and beverage processing plants, health care facilities, pharmaceutical, laboratories, animal care facilities, wash bays, locker and shower rooms
  • Used in new construction, renovation and maintenance work

Consumption

Coverage

50– 80 ft2 / US gal (1.2–2.0 m2 / L) at 20-33 mils wet film thickness (w.f.t.) / 10-16 mils dry film thickness d.f.t

Typically, one coat is required, although on more porous surfaces a second coat may be required. Actual coverage rates and material consumption will depend upon porosity and profile of substrates. Test areas are recommended to establish correct coverage rates.
Application steps

MIXING

Thoroughly pre-mix each component separately to ensure that all solids are distributed throughout and to ensure product uniformity. Empty Component B in the correct mix ratio to Component A into a suitable size mixing container for the volume of material being mixed. Mix the combined components for at least 3 minutes, using a low-speed drill (200–300 rpm) to minimize entrapping air. Use an Exomixer type mixing paddle (recommended model) suited to the volume of the mixing container.

 

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. When completely mixed, Sikagard® Duroplast EE should be uniform in color and consistency. Allow the mixed material to stand (induction time) for 1 hour, then lightly remix to ensure uniformity before applying. Failure to do so will result in unsatisfactory performance. Mix only that quantity which can be used within its pot life.

APPLICATION

Tape off and mask all areas that require protection. It is recommended that suitable cleaning rags and clean warm water is on hand to remove accidental spills.

                  

Sikagard® Duroplast EE can be applied by brush, roller or spray equipment, dependent on limitatiions and site conditions. If sprayed, the material must be back rolled/brushed to ensure good penetration of the blockfiller into the substrate.

                 

Sikagard® Duroplast EE must be applied in a workmanlike manner using skilled and trade qualified applicators. The film thicknesses stated must be produced and complete coverage achieved (This condition may require a second coat).

            

After application and prior to drying, remove masking tape in between each coat to avoid ‘ripping’ in the finished coating and let surfaces dry completely. Sand off any rough spots and visible defects with a fine sandpaper (120–220 grit), then vacuum and wipe surface to remove all residual traces of sanding dust.
