Do I always need to use a primer?

Not always, but many manufacturers recommend primers for difficult or porous substrates. Using a primer is especially important when working with materials like concrete, masonry, or certain plastics to avoid adhesion failure.

Can primers be used on outdoor surfaces?

Yes, many primers are suitable for external use and help improve resistance to moisture, weathering, and environmental exposure. Always choose a primer compatible with your substrate and intended application.

What types of primers are available?

There are primers for porous and non-porous surfaces, as well as specialist options for metal, concrete, timber, and plastics. Selecting the correct type ensures optimal performance and compatibility with your sealant or coating.
