  • Ablative mechanism inhibits the attatchment of fouling organisms
  • Cost effective performance
  • Controls common types of fouling for periods up to 12 months per coat, depending on sailing pattern applied systeem
  • Compatible with most suitably prepared copper based anti-foulings
  • Recommended Uses:
  • It is recommended for both launches and yachts and will typically provide up to 18 months protection from a two-coat system.
  • Coastal Copper antifouling is an ablative coating - being harder than Altex NO. 5, and therefore or experience higher wear than normal. Vessels that are moored in highly tidal areas ( that can ablate softer coatings too readily) are well suited to Coastal Copper.

How Much Paint Do I Need?

Calculate / Approximate the surface area in square metres of of the hull below the waterline. Divide that number by 6. That will give you the number of litres, for a single coat, based on 80-90 microns thick. Double that number to get the total required for two coats. Apply ALL of that colume (even if it takes you several coats). You will then have maximum protection.

  • Density: 1.79 kg per litre
  • VOC: 414G pre Litre
  • Volume Solids: 52%

Theoretical Coverage Rate:

  • 5.2sq. metres per litre at 100 microns dry
  • 6.9sq. metres per litre at 75 microns dry

Recommended Film Thickness Per Coat:

  • 192 microns wet to obtain 100 microns dry
  • 145 microns wet to obtain 75 microns dry

(Typically two spray applied coats (at 75 microns each) equates to three roller applied coats to achieve the same film thickness)

  • Application: Spray, Brush, or Roller

Reccommend Dry Times Times(100µm DFT / 25oC / 50% RH):

  • Dry to Recoat: Minimum 6 hours. Maximum - not critical
  • To Launch: Minimum 8 hours
