UPOL Primer

Why Apply a Primer?

A primer creates a stable surface that ensures proper adhesion of the new paint. Applying paint directly to the bodywork does not guarantee durability or a flawless finish. The primer helps mask imperfections, prevents rust, and extends the lifespan of the coating.

When to Apply a Primer

Applying a primer is essential to achieve a solid, uniform result. It is particularly recommended when:

• The surface is too porous and would otherwise require several coats of paint

• The bodywork is too smooth or glossy, reducing paint adhesion

• The surface has never been painted before

• You are using water-based paint

• You are changing color shades (from dark to light or vice versa)

How to Choose the Right Primer

The choice of primer depends on the color, substrate, and intended use:

• Water-based primers: eco-friendly, fast-drying, easy to clean with water, and low odor

• Oil-based primers: suitable for difficult surfaces, cleaned with thinner, stronger odor

• Filler primers: fill surface defects and irregularities

• Wet-on-wet primers: require no sanding, helping improve productivity

• White primer: for white, yellow, light orange, and tri-coat finishes
