APPLICATION AND USE
Preparation: PREVIOUSLY PAINTED SURFACES
In Good Condition Wash down with Super Cleaner, rinse with fresh water and allow to dry. Abrade with 280-320 grade (grit) paper.
In Poor Condition: Remove all previous coatings and prime the substrate.
PRIMING All preparation for bare substrates is covered on the appropriate primer datasheet.
BARE WOOD Prime with Interprotect.
STEEL Prime with Interprotect.
ALUMINIUM Prime with Interprotect.
GRP Wash down with Super Cleaner, rinse with fresh water and allow to dry. Abrade with 180-220 grade paper.
AGED/WEATHERED GELCOATS Degrease with solvent or suitable detergent cleaner. Sand well using 180-220 grade paper. Clean thoroughly and allow to dry completely. To avoid potential pinholing, apply 3 coats of an International 2 pack epoxy primer which must be then overcoated with an International 2 pack undercoat prior to topcoat application.
ALL SUBSTRATES If any filling is required use the appropriate product from the International range.
Method If maximum overcoating time of previous coating/primer is exceeded, abrade using 180-220 grade paper. Remove dust with a dust wipe. Apply 1-2 coats.
TIPS: Mixing Stir contents of each part prior to mixing. Add Curing Agent to the Base, stir and leave for 10 minutes to allow bubbles to disperse.
