Flammability / Fire Rating:

Gloss (before & after 10 000 cycle scrubbability evaluation)

A:B = 4:1 (by volume)

Condition product at temperatures between 18 °C and 30 °C (65 °F and 86 °F) before using and during the application.

Minimum: 10 °C (50 °F)  Maximum: 30 °C (86 °F)

Note: Mixing carried out under conditions where the Sikagard® Duroplast-100 N temperature and ambient temperature are below 18°C (65°F) will result in reduced product workability and slower curing rates.

Maximum 85 % (during application and curing).

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 temperature.

Minimum: 10 °C (50 °F)  Maximum: 30 °C (86 °F) 

Note: Mixing and application attempted at material, ambient and /or substrate temperature conditions less than 18 °C (65 °F) will result in an increase of the viscosity of the Sikagard® Duroplast-100 N and slower cure rates.

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 / masonry surfaces prior to application: 28 days (depending on curing and drying conditions).

Minimum age of SikaTop® or Sika MonoTop® mortar prior to application is 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).

Note:

• Drying times will vary according to ambient air and substrate temperature and relative humidity.
• Protect from dampness, condensation and water contact during the initial 24 hour cure period.

IMPORTANT: If the maximum waiting time has been exceeded. The previous coat must be lightly sanded, to remove all gloss; vacuum cleaning using a brush attachment followed promptly with a solvent wipe off the surface as per the following generally accepted practices:

• Avoid using solvent that can leave a oily residue: (such as, but not limited to most mineral spirit).
• Avoid Paper Towels: Pre-treated shop towels or standard paper towels may contain silicone or manufacturing additives that will ruin your paint job. Stick to lint-free cotton cloths or dedicated microfiber towels.   
• Change Rags Frequently: As soon as a rag becomes visibly dirty, discard it or fold it to a clean side. Continuing to wipe with a saturated, dirty rag just re-deposits contaminants onto the surface.    
• Wet Wipe: Pour a solvent (onto the first rag. Do not dip the rag into the solvent container; pour it directly to keep your supply clean).   
• Lift: Wipe down a small, manageable section (e.g., ~0.5 m² [~ 4-6 ft²]) of the surface. Use enough pressure to break up and lift the oils or sanding dust. Rotate the cloth frequently so you are always using a clean spot.  
• Dry Wipe: Before the solvent can flash off (evaporate) and dry on the surface, wipe the same section with a second, clean, lint-free rag. When used correctly, this second cloth absorbs residual solvent and removes materials that could reduce or prevent adhesion or the proper performance of the next coat.

Xylene: at a maximum 5 % by volume (if required: 50 mL/L (6.4 oz/US gal.)

Note: This may reduce sag resistance of Sikagard® Duroplast-100 N.

5 m²/L to 6.7 m²/L (202 ft²/US gal to 270 ft²/US gal) per coat 6 mil to 8 mil (w.f.t.)  Typically two (2) coats are required, however, on higher absorbency substrates, additional coats may be required.

Note: Actual coverage rates and material consumption will depend upon porosity and profile of the substrate.  Test areas are recommended to establish correct coverage rates.

Mixing ratio A:B = 4:1 (by volume)

IMPORTANT: Do not hand mix Sikagard® Duroplast-100 N; mechanically mix only.  

Pre-stir each component separately to ensure that all soft settling is dispersed, solids are evenly distributed and even colours and consistencies are achieved within each component.  

Empty Component B in the correct mix ratio to Component A into a suitably sized, clean mixing vessel. Mix the combined components for at least three (3) minutes, using a low-speed drill (200 - 300 rpm) fitted with an Exomixer® or Jiffy type mixing 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 attempt to attend to unmixed material that may gather on the sides of the mixing container while mechanical or electrical parts are in motion. When completely mixed, Sikagard® Duroplast-100 N should be uniform in colour and consistency.

Note: Do not mix more material than can be applied within the working time limits (i.e. Pot Life) at the actual field temperature.

Sikagard® Duroplast-100 N may 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 advice (thinning may be required) contact Sika Canada.

Sikagard® Duroplast-100 N 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 all tools and equipment with a non-flammable solvent. Once hardened, product can only be removed mechanically.
