Sikalastic® Primer EPDM

12 months

Store dry between 41 °F and 86 °F (5–30 °C)

0.779 kg/l

-22–176 °F (-30–80 °C) intermittent

41 °F (5 °C) min. / 95 °F (35 °C) max.

80 % R.H. max.

Not for use on surfaces wth condensation. Air, substrate and uncured coating must be ≥ 5 °F (3 °C) above dew point.

41 °F (5 °C) min. / 140 °F (60 °C) max.

Once opened, the product should be used and reasealed promptly. Sikalastic® Primer EPDM does not react with atmospheric moisture allowing it to be opened and resealed for use at a later date.

Allow primer to dry completely before applying resins (typically within 40 minutes). Primer will visually appear “dull” or “flat” and will feel dry to the touch. Drying conditions will vary depending on ambient air conditions. Use caution when installing at temperatures below 40°F (5°C) to prevent blushing of Sikalastic® Primer EPDM (formation of condensation on surface of primer). 

200 - 250 sq.ft./ gal.

All work surfaces should be clean, dry, free of dirt, dust, debris, oils, unadhered coatings, deteriorated membrane and other contaminants that may result in a surface that is not sound or is uneven. If necessary, clean the surface with mineral spirits or VM&P naptha prior to application of Sikalastic® Primer EPDM.

Shake or stir the 1 gal. (3.8 L) can of Sikalastic® Primer EPDM for 30 seconds prior to application.

Do not dilute or extend Sikalastic® Primer EPDM. Surfaces should be dry and clean before applying Sikalastic® Primer EPDM. EPDM and TPO surfaces should be cleaned with a suitable solvent such as mineral spirits prior to priming. Observe all manufacturers’ safety precautions and use recommendations when using solvents.  When the surfaces are dry, apply Sikalastic® Primer EPDM with a fully saturated roller or brush. Some applications may require the use of a scouring pad to acheive proper adhesion. Always complete an adhesion test before application.  If using a scouring pad, be sure that it is free of excessive dust from EPDM membranes. Replace pads often. The surface should appear wet during application. Do not overwork primer.   Apply Sikalastic® Primer EPDM 2" past actual applicaiton area to insure complete coverage.

Allow primer to dry completely before applying resins (typically within 40 minutes). Primer will visually appear “dull” or “flat” and will feel dry to the touch. Drying conditions will vary depending on ambient air conditions. When not in use, keep lid on primer to prevent solvent evaporation. When finished, secure lid and store primer as recommended for use at a later date. Use caution when installing at temperatures below 40°F (5°C) to prevent blushing of Sikalastic® Primer EPDM (formation of condensation on surface of primer).
