Painting above the waterline
Surface preparation Preparation is the key. Good preparation will result in a beautiful finish. So takeyour time.Loose paint should be removed by scraping back to a sound substrate. Largerareas can be dealt with by slurry blasting or mechanical sanding. However, most
chemical paint strippers should never be used on glass fibre, as they will quickly
destroy the protective gel coat.UseSEAJETThinner to remove any grease spots. Then wash and degrease withSEAJET
BOAT WASH. Sanding is required to obtain a smooth surface and key the surface. Surfaces tobe painted must be clean, dry and free of oil or grease. Existing paints need to be
sanded to remove small lumps and blebs in the paintwork. Flatten back with
P180-P280 abrasive paper. Finally, brush off dust and use lint free tack rags to
remove remaining traces of dust. Preparation can vary depending on the surface to be coated, so follow our painting specification for specific details of preparation.
Topcoats
Before we start painting SEAJET topcoats are designed to protect your boat against the elements andkeep her looking like new. Where conventional alkyd paints can soon fade and need repainting regularly, SEAJET topcoats provide a longer term solution.
The main benefit is that you need to paint less frequently than when using conventional paints. This is due to:? Improved gloss retention? Improved colour retention
? Improved resistance to UV light
? A tougher, harder surface which is more resistant to knocks and scratches Repaintingintervaldependsupontheambientsunlight,whichvariesaroundtheworld.FortheCaribbeanandMediterranean,reducetheabovefiguresbyhalf.

yearsNote: So how do we tackle the painting work? Firstly, youll need to wear the right clothing. Painting can be a messy job, so youll need old clothes or a pair of
overalls; rubber gloves; and a hat. We also recommend that you wear a pair of
safety
marine glasses.TIP: Dont paint while wearing a woolly sweater or hat as the fibres will get ontothe paintwork. Youll also need a few basic tools, including a scraper for scraping off any loosepaint; some wet or dry paper and sanding blocks to key the surface by sanding
down; and brushes or a roller for putting your new paint on. And dont forget
some masking tape to
marine mask off the waterline. 34
