APPLICATION AND USE

Preparation

Wash all surfaces except STEEL with Super Cleaner.

BARE GRP

Sand using 180220 grade (grit) paper. Apply 1 coat of Primocon.

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). Apply 1 coat of Primocon (thinned 1015% Thinner No. 3) + 3 more coats.

ALUMINIUM

Degrease with solvent, Super Cleaner or a suitable liquid detergent. Sand well using 24120 grade (aluminium compatible) paper. Coarser grades 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. Apply 1 coat of Primocon (thinned 1015% Thinner No. 3) + 5 more coats.

ZINC/GALVANISED STEEL

Degrease with solvent, Super Cleaner or a suitable liquid detergent. Sand well using 60120 grade paper. Clean thoroughly and allow to dry completely. Preprime using an International primer as detailed for specific coating systems. Apply 1 coat of Primocon (thinned 1015% Thinner No. 3) + 5 more coats.

LEAD

Degrease with solvent, Super Cleaner or a suitable liquid detergent. 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. Apply 1 coat of Primocon (thinned 1015% Thinner No. 3) + 5 more coats.

STEEL

Gritblast to Sa 2½ near white metal surface. If gritblasting is not possible, grind 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. Apply 1 coat of Primocon (thinned 1015% Thinner No. 3) + 5 more coats.

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. Hints Mixing: Stir well before use.

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.  Before sealing old antifouling layers, boat owners must check and comply with local legislative requirements.

Primocon prevents leaching of TBT from an underlying antifouling dry film thickness of 80 microns (minimum of 2 coats by roller). We have studied the leaching rate of TBT from a TBT SPC antifouling (Superyacht 900) overcoated with Primocon (applied as specified) & seen that TBT leaching is prevented. The leaching rate determination method used was ASTM D510890 (2002) Standard Test Method for Organotin Release Rates of Antifouling Coating Systems in Sea Water.
