Bulk Application Steps
1) Mix 2-part kit. Mix when temperatures are between 65°F and 90°F (18°C and 32°C).
- Pour Part A into Part B container
- Reseal the Part B container and shake for 5 minutes
- There is no induction time for Sur-Prep® AP-1. Pot life of Sur-Prep® AP-1 is 24 hours. If white particles are noticed in Sur-Prep® AP-1 after it was mixed, discard the product and make a fresh mix.
- Pour mixture into used container. Keep used container covered until ready for application.
2) Apply with HVLP, air assisted, airless, or electrostatic paint gun.
3) Apply as a thin film and make sure that the surface is damp (gloss on paint surface will change).
4) Apply next decorative paint coat or stencil paint within 24 hours.
5) Once applied, the surface coated with Sur-Prep® AP-1 shall not be touched or disturbed prior to application of any subsequent coating.
6) Clean spray equipment with methyl propyl ketone (MPK) or 70/30 MPK/methyl ethyl ketone (MEK) mixture.
7) Allow the film to dry 30 minutes for large area and 15 minutes for stencil use.
Note: Sur-Prep® AP-1 Part A and Part B should not be mixed as partial kits because Sur-Prep® AP-1 absorbs moisture from the air and can contaminate the compound. When Sur-Prep® AP-1 Part A receives moisture, a slight particulate form in the liquid will be seen. For Sur-Prep® AP-1 Part B, there will be no change in the liquid even if moisture is absorbed. If Sur-Prep® AP-1 Part A is mixed in with Sur-Prep® AP-1 Part B when moisture is present in Part B, then there will be a slight precipitate form in the Sur-Prep® AP-1. If there is cloudiness in the Sur-Prep® AP-1 Part A or the Sur-Prep® AP-1 Part A and Part B materials combined, then the Sur-Prep® AP-1 Part A and Part B must be discarded. The mix ratio for Sur-Prep® AP-1 should be 6.3 parts by weight of Sur-Prep® AP-1 Part B to 1 part by weight of Sur-Prep® AP-1 Part A.
Aerosol Application Steps
1) Shake aerosol can for 10-15 seconds.
2) Apply a thin film and dampen the surface (gloss on paint surface will change).
3) Allow film to dry 30 minutes for large area and 15 minutes for stencil use.
4) Apply next decorative paint coat or stencil paint within 24 hours.
Note: If any defects occur during application (runny or areas are heavily dampened), dry the area with compressed air. Remove the dried powder using a solvent, such as MPK or 70/30 MPK/MEK mixture. A tack rag can also be used as well. Reapply a thin wet film of Sur-Prep® AP-1. If the second coat of paint is not applied over Sur-Prep® AP-1 within 24 hours, remove the dried powder using a solvent, such as MPK or 70/30 MPK/MEK mixture. A tack rag can also be used as well. Re-apply a thin and wet film of Sur-Prep® AP-1.
5) Once applied, the surface coated with Sur-Prep® AP-1 shall not be touched or disturbed prior to application of any subsequent coating.
