Application steps

MIXING

Premix Component A and Component B components using a mechanical mixer (Jiffy) at slow speed to obtain uniform colour, making sure to scrape the solids from the bottom and sides of the pail. Pour Component B into Component A slowly and while mixing scrape the side of the container. Mix the combined material thoroughly for typically three (3) minutes until a homogenous mixture and uniform colour are obtained.

 
When mixing, use care not to entrap air into the mixture. Sikalastic® Recoat Primer can be applied with or without Sikalastic®-700 ACL Accelerator as an accelerator. In the event that Sikalastic®-700 ACL Accelerator is used, add 946 mL (2 US qts) of Sikalastic®-700 ACL Accelerator into 37.8 L (10 US gal.) of mixed primer. Mix the combined material thoroughly until a homogenous mixture and uniform colour is obtained (typically 3 minutes). When mixing, use care not to entrap air into the mixture.

APPLICATION

Apply at the recommended coverage rate, typically 1 L per 7.3 m2 (1 US gal. per 300 ft2) at 5 mil w.f.t., using a phenolic resin core roller. Coverage rate will depend on surface roughness and porosity. Reference Typical Data section for curing and recoat guidelines.

Over Painting

Sikalastic® Recoat Primer without Sikalastic®-700 ACL Accelerator should be recoated within 12 hours once tack-free or within 6 hours (once tack-free) if Sikalastic®-700 ACL Accelerator is used.

CLEAN UP

Remove liquid primer immediately with dry cloth. Once cured, primer can only be removed by mechanical means.
