Antifouling a Squib

t wex

Looking for some advice on what paint to use on the underside of a squib?

Any advice would be greatly appreciated

To get a good smooth finish I would use interlux micron, there are 3 different types depending on what you use the boat for and in what water.:)

Thanks for the advice Fergal.

Squib is used for racing in silty salt water of Wexford Harbour and is kept on a mooring.

I've brought it back to the bare hull, is there anything that should go on before Micron or can this go straight on?

Thanks
Tom

On bare fiberglass you will need primer here are a few tips.

BARE FIBERGLASS - (POLYESTER OR VINYLESTER): Clean and degrease with Fibreglass Solvent Wash 202 or use Fibreglass Surface Prep.
No Sand System -: Repair defects with Watertite, then sand and wipe clean. Apply one thin, continuous coat of Interlux Fiberglass No-Sand Primer. See primer datasheets for details on substrate preparation.
Sanding System -: Sand with 80 grade (grit) paper. Wipe with Fiberglass Solvent Wash 202. Repair defects with Watertite, then sand and wipe clean.
BARE WOOD: Sand with 80 grade (grit) paper. Clean with Special Thinner 216. Apply first coat reduced 10% with Special Thinner 216 or Brush-Ease 433. Fill seams, if necessary, with Seam Compound Brown 30. Repair defects with Watertite, then sand and wipe clean. Apply 2 additional coats.
STEEL/ALUMINIUM: Contact the Interlux Technical Service Department at 1-800-468-7589 for full information on how to properly prime underwater metals.


Method At least 2 coats should be applied. Apply an extra stripe coat in areas of high wear such as chines, rudders, sterngear and any leading edges.


Hints Thinner Special Thinner 216 or Brush-Ease 433.
Cleaner Painted Surfaces - Special Thinner 216. Bare Fiberglass - Fiberglass Solvent Wash 202 or Fiberglass Surface Prep YMA601. Bare Wood - Brush-Ease 433.
Airless Spray Spraying can be done using the correct safety and spray equipment. Contact Interlux Technical Service for more information.
Conventional Spray Spraying can be done using the correct safety and spray equipment. Contact Interlux Technical Service for more information.


Some Important Points Product temperature should be minimum 5°C/40°F and maximum 35°C/95°F. Ambient temperature should be minimum 5°C/40°F and maximum 35°C/95°F. Substrate temperature should be minimum 5°C/40°F and maximum 35°C/95°F.


Compatibility/Substrates Surface must be dry and clean, and free from grease, detaching paint etc. Micron 66 can be applied to most popular antifouling paints as long as the old coating has been aged, is tightly adhered and is in sound condition. Do not apply Micron 66 over aluminum. Use Primocon primer as a conversion coat prior to application over tin-based copolymer antifouling paints.


Number of Coats 2-3 minimum Bare Wood: 3 coats (first thinned)


Coverage (Theoretical) - 320 (ft²/Gal) by brush/roller


Recommended DFT 2.0 mils dry
Recommended WFT 5.1 mils wet


Application Methods Brush, Roller
