Types of Primer
1. Oil Based Primer
Oil based primer is mainly used for wood work, i.e. new wood, painted wood, dry wood, etc. It can be used on metal surfaces as well. It is suitable for both interior and exterior application.
The drawback of oil based primer is that they are often slow drying, generally 24 hours or more. It releases high amounts of volatile organic compounds (VOC), which can be harmful to people if in high concentrations and for prolonged exposure.
Oil primers are known for their smooth finish, ability to penetrate the wood grain by filling pores without raising the grain. This means that little or no sanding is required to achieve a smooth surface.
Oil-based primers are good to use for new and unfinished wood and wood prone to weathering, to provide an extra wear-layer.
2. Water Based Primer
Water based primer is usually used for walls and ceilings where there is new work and preparation is required. These are made to apply on multiple surfaces and are growing in preference because of their low odour, low-VOC formulations that make them environmentally friendly, while still providing a flexible and crack-resistant finish.
They also allow water vapour to pass through, and make the surface less prone to peeling. Use water-based primers on concrete, brick, new softwoods, unfinished drywall etc.
