APPLICATION AND USE

Preparation PRIMING

Watertite can be applied over most International 1 and 2 pack primers. Ensure primer is sanded with minimum P280 grit and cleaned thoroughly.

PREVIOUSLY PAINTED SURFACE

In Good Condition:

Above water

Wash down with a suitable detergent, rinse with fresh water and allow to dry. Sand with 220280 grade (grit) paper. Clean thoroughly and allow to dry completely. Preprime using an International primer as detailed for specific coating systems. Below water All fouling and contamination must be thoroughly removed including the leached layer. Use high pressure fresh water wash (3000 psi/207 bar) and/or scraping and wet sanding with typically 80120 grade paper. Do not dry sand. If old antifouling is incompatible or unknown, seal with suitable International Paint barrier/sealer coat. RePrime where necessary.

In Poor Condition

Remove all antifouling and other loosely adhering and flaking material, feather back all edges and wet sand all areas. Areas taken back to substrate should be treated as recommended for substrates detailed below.

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 primer. Prime using an International primer as detailed for specific coating systems.

STEEL

Degrease with solvent, Super Cleaner or a suitable liquid detergent. 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 well roughened metal surface 5075microns anchor pattern. Use angle grinder on small areas. Clean thoroughly and allow to dry completely. Prime using a recommended International primer as soon as possible (within 8 hours) as detailed for specific coating systems.

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 completely. Prime using a recommended International primer as soon as possible (within 8 hours) as detailed for specific coating systems.

ZINC/GALVANISED STEEL

Degrease with solvent or a suitable liquid detergent. Sand well using 60120 grade paper. Clean thoroughly and allow to dry completely. Prime using a recommended International primer as soon as possible (within 8 hours) as detailed for specific coating systems.

GRP/EPOXY

Degrease with solvent or a suitable liquid detergent. Sand well using 180220 grade paper. Clean thoroughly and allow to dry completely. Preprime using an International primer as detailed for specific coating systems. When treating osmosis, use Gelshield Plus prior to application of 1st coat of epoxy primer.

LEAD

Degrease with solvent or a suitable liquid detergent. Sand well using 120 grade paper or power wire brush. Clean thoroughly and allow to dry. Prime using a recommended International primer as soon as possible (within 8 hours) as detailed for specific coating systems. Method Remove any dust from the surface. Apply firmly in a spreading action. Fill to a level slightly above the surrounding area. When hardened, sand smooth with 80220 grade wet or dry paper. If left longer than 24 hours, two component epoxy fillers will need sanding with 80220 grade wet or dry paper to ensure a good physical key.

Hints

Mixing: Mix the two components thoroughly to an even colour. Mix both components together thoroughly to correct mix ratio.

Thinning: Do not thin.

Cleaner: YTA061 International Epoxy Thinner No 7.

Ventilation and Humidity Control: Avoid cold, damp conditions which may cause a stickiness to form on the surface. This should be removed by water and a 3M Scotchbrite pad or sanding.

Other: Large areas should be sanded with paper on a board twice the length of the repair area, this will allow for curvature of the hull. Small areas can be sanded using a sanding block. Sand as soon as possible after the sandable time as Watertite continues to harden with time.
