AquaMarine HULL Surface Preparation

Ensure the boat bottom is clean and free of all forms of fouling such as coral worm or barnacles. If necessary undertake an acid wash to ensure all residue is removed and that any previous antifoul paint is completely removed. Follow the instructions below for new surfaces and for previously antifouled surfaces as appropriate.


  1. Abrade lightly with an orbital sander using P220 grade paper to promote adhesion.
  2. Wash surface thoroughly using AquaMarine PREP WASH.
  3. Rinse the surface thoroughly with clean water, ensuring you remove all traces of AquaMarine PREP WASH.
  4. Make sure that the AquaMarine PREP WASH does not dry onto the hull.
  5. In hot weather we recommended the surfaces being cleaned are pre-sprayed with cold water to cool them before application.


  1. Remove all antifoul back to the epoxy. Inspect the boat bottom for any signs of damage and repair where applicable BEFORE AquaMarine Hull application.
  2. Once the boat bottom is ready, lightly abrade with sandpaper to produce a smooth finish.
  3. Full preparation of the substrate will mean the end result will be better so plan accordingly.
  4. Wash the boat bottom surface thoroughly using AquaMarine Prep. Rinse the surface thoroughly with clean water, ensuring all traces of AquaMarine Prep are removed. It is best not to allow the AquaMarine Prep wash to dry onto the boat bottom.
  5. In hot weather we recommend the surfaces being cleaned are cooled with cold water before application.
  6. Once dry, apply two coats of two-part epoxy. We recommend Internationals’ ‘Interprotect’ two-part epoxy primer. Once the epoxy is touch dry, i.e. a thumb print can be left on the surface but no traces of epoxy come off onto your skin, AquaMarine Base should be applied, to ensure a good bond between the coatings is achieved.

HULL FINISH system creates an extremely slippery surface, especially when wet. When lifting the vessel in an out of the water it is strongly advised that the front and rear support slings are secured together with a tether to prevent the slings from sliding apart. Additionally, we recommend that the lifting slings are tied to the top side cleats. Foam pads should be used between cradle / support legs and the hull to avoid slippage.


AquaMarine HULL Application


Please refer to all MSDS and Data Sheets before application of AquaMarine HULL.


AquaMarine HULL BASE


Apply 'plastic' masking tape around the boat bottom at the water line. Mask areas such as anodes where protection is not required.


Preferably bring the HULL BASE paint to 5-20°C for easy application. If the product is too cold it will be very viscous to work with.

Material supplied is ready to use.

Stir contents well prior to use.


HULL BASE is a high quality, deeply pigmented viscous paint that becomes mobile when applied.

HULL BASE requires one coat of 100 Microns (WFT). If covering over an opposing colour, a second thinner coat may be required.

Apply using the reticulated roller heads supplied.

Apply the coating with firm vertical and then horizontal strokes to give an even coating.

It is advisable to treat a 1 Metre Square area at a time.

Should there be gaps i.e; where support props have been moved, HULL BASE can be applied over the gap, ensuring that it overlaps the existing coating by at least 25mm.



Apply 'plastic' masking tape around the hull at the water line. Mask areas such as anodes where protection is not required.


Stir tin contents well before use. If the paint is too viscous, place the tin in a warm water bath.


HULL FINISH only requires one coat. To achieve the correct coating thickness (100 microns) apply HULL FINISH with a fine haired roller. Do not apply too much coating as it may run. At 100 microns it will form a good even cover and self-level.

Should there be gaps i.e: where support props have been moved, HULL FINISH can be applied over hte gap (even when it has cured) ensuring that it overlaps the existing coating by at least 25mm.

After applying HULL FINISH, ideally the vessel should be left for 36 hours before the boat is returned to the water.




AquaMarine HULL Maintenance



Dive cleaning, otherwise known as boat bottom cleaning, is a convenient and cost effective method of maintaining the underside of your vessel between lifting.

In most cases all foul can be removed from a vessel’s hull, propeller and underwater running gear to return peak performance by simply using a rubber squeegee or foam sponge, leaving your boat clean and the organisms in their natural environment.

Most marinas worldwide will offer this service either as a one-off dive or as part of a regular maintenance program.


Scrubbis Brush

Scrubbis makes it easy to remove algae and other coatings from your hull. You clean it by yourself while the boat is in the water. The cleaning head has a buoyancy of 2 kg which continuously push it against the hull and flexible flanges which follows the shape of the hull and keel. Scrubbis should be used regularly from once a month to once a week depending on the water.



Once out of the water the hull should be lightly power washed to remove any fouling that has managed to attach itself. Any stubborn organisms can be easily removed by using a rubber scraper.
