International Primocon Primer
Tarfree, quick drying conventional one part primer for all substrates underwater. Can be used under all International antifoulings or as a barrier/sealer coat over incompatible or unknown antifoulings.
* Primocon prevents leaching of TBT from an underlying antifouling coating provided it is applied at a minimum dry film thickness of 80 microns (minimum 2 coats by roller) & that the film remains intact.

Note: For all other International antifoulings such as Cruiser Uno EU, Boatguard EU, Ultra EU, Cruiser Polishing Antifouling, Cruiser Premium Plus, Micron Superior, Navigator and Trilux Hard Antifouling, use the Micron Extra EU overcoating times. If maximum overcoating time has been exceeded, sand using 80180 grade (grit) paper. Drying times refer to brush and roller application.
APPLICATION AND USE
Preparation: Wash all surfaces except STEEL with Super Cleaner.
BARE GRP: Sand using 180220 grade (grit) paper.
BARE WOOD/PLYWOOD: Sand smooth with 80180 and then 280 grade paper. Remove sanding dust by brushing,dusting and wiping. If wiping with solvent then allow to dry completely before applying products recommended for application direct to wood (see specific coating systems).
ALUMINIUM: Degrease with solvent or Super Cleaner. Sand well using 24120 grit (aluminium compatible) paper.
Coarser grits are recommended to achieve optimum adhesion. Clean thoroughly and allow to dry. Preprime using an
International primer as soon as possible (within 8 hours) as detailed for specific coating systems.
ZINC/GALVANISED STEEL: Degrease with solvent or Super Cleaner. Sand well using 60120 grade paper. Clean thoroughly and allow to dry completely. Preprime using an International primer as detailed for specific coating systems.
LEAD: Degrease with solvent or Super Cleaner. Sand well using 120 grade paper or power wire brush. Clean thoroughly and allow to dry. Preprime using an International primer as detailed for specific coating systems.
STEEL: Gritblast to Sa 2½ near white metal surface. If gritblasting is not possible, sand the metal surface with 2436 grit abrasive discs to a uniform, clean, bright metal surface with a 5075 microns anchor pattern. Use angle grinder on small areas. Preprime with Primocon thinned 1015% with Thinners No.3.
PREVIOUSLY ANTIFOULED SURFACE
In Good Condition: Remove loose material. Wash down with fresh water. Allow to dry.
In Poor Condition: Remove using Interstrip.
Method_ If filling is required, use appropriate filler after the first coat of Primocon has been applied. Before painting, remove any dust with a dust wipe. Apply the following number of coats: GRP 1, Wood/Plywood 3, Aluminium/Alloy/Zinc/Galvanised Steel/Lead/Steel 5, Barrier/Sealer coat 1.
Tips: Mixing: Stir well before use. Thinner YTA085 Thinners No.3 GTA007.
Cleaner YTA085 Thinners No.3
Airless Spray Pressure: 211 bar. Tip Size: 21802680.
Some Important Points: Do not use below 5°C. Do not overcoat with 2component products. Ambient temperature should be minimum 5°C/41°F and maximum 35°C/95°F. Product temperature should be minimum 5°C/41°F and maximum 35°C/95°F. Substrate temperature should be 3°C/5°F above dew point and maximum 35°C/95°F. Under certain application conditions it may not be possible to achieve 40 microns dry film thickness in a single coat application. For application to GRP a single coat of Primocon is suitable providing that the dry film thickness is 20 microns or above. For other substrates further coats than that stated should be applied to ensure adequate film thickness is applied for protection of the substrate. Primocon prevents leaching of TBT from an underlying antifouling dry film thickness of 80 microns (minimum of 2 coats by roller).
Compatibility/Substrates: Suitable for all substrates specified.
Number of Coats: 15 by brush depending on substrate

(Practical) 7.4 m²/lt by brush
Recommended DFT per coat 40 microns dry
Recommended WFT per coat 121 microns wet
