Air and surface temperature must be above +5 °C and relative humidity below 85%; surface temperature must be at least 3 °C above the dew point.
SUITABLE BOAT TYPES
Technical data are average values at 20 °C and 65% relative humidity. Coverage varies with surface roughness, application method and film thickness. Consult the Gen Boya technical team for a paint schedule tailored to your boat.
