Sikagard®-150 N Duroplast®
Sikagard®-150 N Duroplast® is a two-part, high solids, low odour, low VOC, fine-textured, pigmented, water-based epoxy wall coating. It produces a durable, easy to clean ceramic-like finish on interior surfaces in a range of gloss levels. Sikagard®-150 N Duroplast® demonstrates superior UV resistance to colour change compared to traditional epoxy coatings. Can be applied over properly prepared and primed, concrete masonry, common steel, or gypsum board substrates. It is fully compatible as a system component (body coat and or top coat) in all Sikagard® Duroplast® epoxy wall coating systems. Sikagard®-150 N Duroplast® contains high performance resins that naturally inhibit the growth of bacteria, molds, mildew and fungi for the lifetime of the coating.

Application
Mixing Ratio
A:B = 2:3 by volume
Ambient Air Temperature
Minimum 10 °C (50 °F ) Maximum 30 °C (86 °F)
Ambient Air Relative Humidity: Maximum 75 % (during application & cure)
NOTE: Mixing and application attempted at low ambient air or substrate temperatures and/or under high humidity conditions, will result in a decrease in product workability and slower cure rates.
Dew Point
Beware of condensation! The substrate must be at least 3 °C (5 °F) above the Dew Point to reduce the risk of condensation, which may lead to adhesion failure or “blushing” on the finish. Be aware that the substrate temperature may be lower than the ambient air temperature.
Substrate Temperature
Minimum 10 °C (50 °F ) Maximum 30 °C (86 °F).
Substrate Moisture Content
Maximum moisture content of all concrete substrates must be < 4 % by mass (pbw - part by weight) when measured with a calibrated moisture meter for concrete (Tramex CME/CMExpert). Masonry surfaces, gypsum board and plaster must be below 85 (green zone on the reference scale) when measured with a calibrated electronic moisture meter (Delmhorst Model BD-10).
Minimum age of concrete and masonry surfaces prior to application: 28 days (depending on curing and drying conditions).
Minimum age of SikaTop® or Sika MonoTop® mortar prior to application: three (3) days, depending on curing and drying conditions. Moisture content must be < 4 % by mass (pbw - parts by weight) when measured with a calibrated moisture meter for concrete (Tramex CME/CMExpert).
Waiting Time / Overcoating
Before application of a second coat Sikagard®-150 N Duroplast®, allow:
Minimum | Maximum | |
10 °C (50 °F) | ~18 hours | ~72 hours |
23 °C (73 °F) | ~10 hours | ~48 hours |
30 °C (86 °F) | ~7 hours | ~24 hours |
Before application of compatible Sikafloor® or Sikagard® coatings, allow:
|
Note: Drying times will vary according to anbient air and substrate temperature and relative humidity.
Pot Life, 250 g (8.8 oz):
23 °C (73 °F) | ~35 minutes |
Full Cure:
23 °C (73 °F) | ~7 days |
Protect from dampness, condensation and water contact during the initial 24 hour cure period.
Consumption
6.5 m²/L to 9.8 m²/L (265 ft²/US gal to 400 ft²/US gal.) per coat (4 mil to 6 mil w.f.t.) (2 mil to 3 mil d.f.t.)
Typically two (2) coats are required, though on higher absorbency substrates additional coats may be required. Actual coverage rates and material consumption will depend upon porosity and profile of the substrate. Test areas are recommended to establish correct coverage rates.
Thinning: Not recommended
MIXING
Mixing Ratio (A:B) = 2:3 by volume.
Do not hand mix Sikagard® Duroplast® resin materials; mechanically mix only.
Pre-stir each component to ensure all soft settling is dispersed, solids are evenly distributed and even colours and consistencies are achieved within each component.
Empty Component A (Resin) in the correct mix ratio into B (Hardener). Mix the combined components for at least three (3) minutes using a low speed drill (200 - 300 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 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.
Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.
APPLICATION
Sikagard®-150 N Duroplast® can be applied by brush, roller or spray equipment, whichever is the most suitable to the surfaces to be coated or site conditions and limitations. For spray applications, contact spray equipment specialists to determine suitable equipment and for application advise.
Sikagard®-150 N Duroplast® must be applied in a workman-like manner using skilled and trade-qualified applicators. The film thicknesses stated must be produced and complete coverage achieved.
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.
Following cure of body coats, 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 before the application of the final top coat.
CLEAN UP
Clean tools & brushes with Sika® Epoxy Cleaner. Once hardened, product can only be removed mechanically.
