Typical Shelf Life	2 years
Substrate	For use over suitably primed GRP, Wood, Steel/Iron and lead. Not suitable for use over Aluminium/Alloy substrates or zinc sprayed surfaces. Can be applied direct over most types of antifouling, provided they are in sound condition, with the exception of VC17m/PTFE antifouling. Consult your local International Paint representative for specific overcoating advice if you are unsure about compatibility of Ultra 300 over your existing coating scheme.
Coverage	by brush/roller: (Theoretical) – 10m²/L per coat  (Practical) – 9m²/L per coat by spray: (Theoretical) – 5m²/L per coat (Practical) – 3m²/L per coat
Number of Coats	by brush/roller: Apply 2 coats of 60 microns dry for 12 months (Total DFT of 120 microns) by spray: Apply 1 coat of 120 microns dry for 12 months (Total DFT of 120 microns) In all schemes, apply an extra stripe coat in areas of high wear such as chines, rudders, stern gear and any leading edges.

 

APPLICATION AND USE

Preparation

PREVIOUSLY ANTIFOULED SURFACE

In Good Condition

All fouling and contamination must be thoroughly removed including the leached layer. Use high pressure fresh water wash (3000 psi/207 bar) and/or scraping and wet sanding with typically 80-120 grade paper. Do not dry sand. If old antifouling is incompatible or unknown, seal with suitable International Paint barrier/sealer coat.

In Poor Condition

Use Interstrip to remove all traces of antifouling.

PRIMING

All preparation for bare substrates is covered on the appropriate primer datasheet.

BARE GRP

Prime with Gelshield 200 for osmosis protection, or Primocon or Interprotect.

STEEL/IRON/LEAD/WOOD

Prime with Interprotect or Primocon.

Hints

Mixing

Thoroughly stir until product is mixed to a uniform consistency before use

Thinning

Thinning is not recommended. Antifouling performance can be compromised if correct dry film thickness is not applied.

Cleaner

YTA085 Thinner No.3

Airless Spray Pressure

176-210 bar/2500-3050 psi. Tip size: 517 to 521.

Ventilation and Humidity Control

Ensure adequate ventilation during use

Other

Antifoulings should only be wet sanded. Never dry sand or burn-off old antifouling. True colour will develop after immersion.

Compatibility/Substrates

For use over suitably primed GRP, Wood, Steel/Iron and lead. Not suitable for use over Aluminium/Alloy substrates or zinc sprayed surfaces.

Can be applied direct over most types of antifouling, provided they are in sound condition, with the exception of VC17m/PTFE antifouling.

Consult your local International Paint representative for specific overcoating advice if you are unsure about compatibility of Ultra 300 over your existing coating scheme.
