For most paints, in order to guarantee efficacy, the only way we recommend changing the color of paints is to mix like paints, ie. Mixing Aluma Hawk with Aluma Hawk. We do not recommend addition of “universal” tints or pigments into our products. Many customers desire an antifouling paint in a deep, dark blue and this can be achieved by mixing blue and black.

Prepping & priming for topside work
Mega Gloss by Blue Water Paint provides a beautiful aesthetic finish, and also provides protection against – sea, rain, wind and sun.
Blistering UV rays will degrade the surface of fiberglass and prematurely age your vessel. Moisture can also cause as many problems for wooden vessels and metal boats.
- Clean and prepare the hull by first washing with soap and water and finish with fresh water. Then wipe the surface with a rag that has been dampened with Naptha.
- After preparing the surface, sand with 220-320 grit wet-or-dry sandpaper. Remove sanding residue by wiping with a rag that has been dampened with Naptha.
- Apply 1-2 coats of Mega Gloss Primer, and 2-3 coats of Finish Paint. Sand between coats with 320-400 grit. If the paint is peeling, cracking or generally showing signs of separations over the whole area, you need to remove the coating.
Applying topside paint
• Stir the paint thoroughly using a stir stick. Stir the can occasionally during work.
• Application methods for all paints include brush,roller or spray.
• It is best to paint on warm dry mornings – cold weather retards the drying of paint and dampness will spoil the gloss.
• Brush – Long flexible bristles are best for gloss paints. Apply by brush, spreading with horizontal strokes before finishing with light vertical strokes. To minimize brush marks, hold the brush at a 45° angle.
• Roller – A good gloss can be obtained using a high density / small cell foam roller. This will minimize the formation of bubbles in the surface. It is best to roll in one direction and tip off in another direction.
• Thinners can be added as you work to maintain working viscosity.
• Pour the amount you expect to use in 30 minutes into a separate container.
• Once topcoat painting is complete, it should be kept dry for at least 24 hours, and 7–10 days should be allowed for full curing to take place.
• Do NOT use or incorporate any flow control agents like Penetrol®.
Application of a topside primer will provide additional depth of color, adhesion and durability.
- The best method is to apply with a roller, and then tip off with a large brush with long flexible bristles.
- Use a diagonal brushing method at 45 degrees, followed by horizontal and then vertical strokes.
- The best roller is a solvent resistant foam roller, which will reduce bubbles.
- Use a top quality fine line masking tape for good crisp lines and no residual glue left on the hull.
Why do the majority of boaters paint with 1-part paint?
Alkyd enamels, and modifications of alkyd enamel technology, have been the work horse products in the marine industry for approximately fifty years. Generally, they dry reasonably fast, are easy to apply and have very good weathering characteristics. More alkyd enamels are still used than any other enamel type.
Can topside paints be applied to below water surfaces?
Most topside coating systems if constantly immersed or kept wet will tend to blister. Provided the boat is only put into the water for a few days then a topside coating can be used below the waterline.
What’s the best way to get a good finish with topsides paints?
You must lightly sand the surface and then use a good roller or brush. Thin when needed for proper flow and performance

Antifouling bottom paint is needed if you store your boat in the water. If left in the water without protection, marine growth may attach to your boat’s exposed hull. Marine growth slows a boat down and increases fuel consumption. Here are the items that you will need in addition to the bottom paint for the proper anti-fouling bottom paint application.
• 60–100 grit – Suitable for the removal of paint or to sand gel coat prior to the application of antifouling paint.
• After sanding remove sanding residue by wiping with a cloth that has been dampened with the proper solvent.
• Masking Tape – When it is necessary to mask off areas use a high quality clean edge masking tape, especially when the masking tape will be left on the surface for a long time.
• Brushes – For antifouling paints use a natural bristle brush but not necessarily one of as good quality as you would use to apply topside finishes.
• Rollers – Most solvent resistant rollers will have a phenolic core and will say that they are for use with oil based paints or epoxies. For antifouling paint and epoxy primers, use a 3/8”-1/2” nap roller.
