-22–176 °F (-30– 80 °C) intermittent

Condition material to 50–77 °F (10–25 °C) before using for ease of application

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.

≤ 6 % moisture content Test method: Sika®-Tramex meter
No rising moisture according to ASTM (Polyethylene-sheet).

45 minutes

Allow primer to cure completely prior to applying membrane resin.

Full cure: 8 hours at 68°F.

Apply membrane resin within 24 hours of primer application. Maximum primer exposure is 3 days. Primer exposed longer than 3 days, exposed to water during curing and exhibiting a chalky appearance, must be reprimed. Deteriorated primer must be mechanically removed before repriming

200 ft²/gal on prepared, dry concrete, depending on substrate profile and porosity.
100 ft²/gal when mixed with 10 lb. 20–40 mesh kiln-dried sand as a 30 mil slurry coat.

Note: Rough, porous, or absorbent surfaces will reduce yield and may require an additional coat of primer.

All substrate surfaces shall be clean, dry and sound. Acceptable substrates include: sound concrete and masonry. Reference separate System Data Sheet for specific surface preparation requirements.

Mix ratio is 1.6:1 (A:B) by volume. Add Part B into Part A and mix with mechanical mixer (Jiffy) at low speed. Avoid adding air into the primer during mixing. When fully mixed, the primer should be free from streaks and of a uniform amber color. Do not break down kits into smaller quantities. For leveling/sealing slurry, add 10 lb. 20–40 mesh kiln-dried sand to mixed primer and mix with mechanical mixer (Jiffy) until a uniform consistency is achieved.

Apply by brush or phenolic resin core roller at the recommended rate. Correct amount of primer will saturate the substrate and leave a slight film on the substrate top surface. Apply evenly without puddling. Apply slurry with flat-bladed squeegee or trowel.

Removal

Remove wet primer with solvent. Once cured, primer can only be removed by mechanical means. Strictly follow solvent manufacturer’s warnings and instructions for use.
