Browse Similar Models by CategoryThis model belongs to: Primer, Alkyd

Key properties

• Economical primer for conventional protective coating systems, suitable for maintenance or new construction projects
• Suitable for superstructures and steel surfaces not immersed in water under normal conditions
• The primer coat does not affect intercoat adhesion with subsequent coats even after prolonged exterior exposure.
• Do not apply over zinc-containing primer surfaces, except for certain interior dry surfaces.
• Can be overcoated with conventional paint systems
• Apply in a cross-coat pattern; a single spray pass can achieve a dry film thickness of up to 75 µm (3 mil).

Colour and gloss

• Yellow, brown, red, grey, dark grey (off-white only available as a custom special order)
• Flat

Recommended substrate condition and temperature

Substrate condition

• Bare steel: abrasive blast clean to Sa 2½ (ISO 8501-1), with surface roughness of 40–70 µm (1.6–2.8 mils).
• Bare steel: power-tool cleaning to at least St2 of ISO 8501-1
• Steel surfaces with pre-treatment shop primer: sweep blasting or power tool cleaning to the corresponding SPSS standard Ss grade or SPSS standard Pt2 grade respectively.
• The previous coat must be clean, dry and free of all contaminants.

Substrate temperature and application conditions

• During application, the substrate temperature must not exceed 50 °C (122 °F)
• During application, the substrate surface temperature must be maintained at least 3 °C (5 °F) above the dew point.

Coating system specification

• Coating system for the boottop and topsides of the hull — system sheet SYSTEM SHEET 3102
• Coating system for decks — system sheet SYSTEM SHEET 3103
• Coating system for superstructures and deck outfitting — system sheet SYSTEM SHEET 3104
• Coating system for internal surfaces — system sheet SYSTEM SHEET 3105

Instructions for use

• Stir thoroughly before use
• Before application, raise the temperature of the components or the mixed paint to above 15 °C (59 °F); otherwise, thinner may need to be added to bring the paint viscosity

adjust to a state suitable for application.

• Excessive thinning generally reduces the sag resistance of the wet film
• During application and curing, ensure continuous, adequate ventilation (see sheets {1433} and {1434})

Safety Precautions

• For the coating and its recommended thinners, see Safety Sheets 1430 and 1431 and the relevant Material Safety Data Sheet
• This is a solvent-borne coating. Avoid inhaling spray mist and solvent vapours, and avoid contact of uncured paint with skin and eyes.
