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

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

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

Maximum 85 % (during application and curing)

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.

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

Note: Any attempt to apply Sikagard® Duroplast PS at substrate temperature conditions less than 18 °C (65 °F) will result in an increase in viscosity and slower drying 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 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).

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.

Note: Typically one (1) coat is required, though on higher absorbency substrates 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.

IMPORTANT: Do not hand mix Sikagard® Duroplast PS; mechanically mix only.  
  

Stir material thoroughly to disperse all solids and liquids, using a slow speed (300 - 450 rpm) drill and Exomixer® or Jiffy type mixing paddle (recommended model) suited to the volume of the mixing container to minimize air entrapment.  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 thorough 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 PS should be uniform in colour and consistency. Should soft settlement have taken place, ensure that solids are dispersed and evenly distributed into the material. The primer/sealer is supplied ready for use and must not be diluted.

Stir for 3 to 5 minutes until a uniform consistency and colour are achieved. It is important to keep the material fully blended; any breaks in application should be followed by re-stirring of the material to again produce a uniform consistency.

Sikagard® Duroplast PS can be applied by brush, roller or spray equipment, whichever is the most suitable to the surfaces to be primed and sealed or site conditions and limitations.  For spray applications, contact spray equipment specialists to determine suitable equipment and for application advise. If the product is to be applied by spraying, Sikagard® Duroplast PS must be back rolled/brushed to ensure good penetration of primer into the substrate. 

Sikagard® Duroplast PS must be applied in a workmanlike manner using skilled and trade qualified applicators. The film thicknesses stated must be produced and complete coverage achieved.

Following cure of primer 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.

Clean tools and brushes with warm water and where required, detergent.  Once hardened, product can only be removed mechanically.
