RM primer

The RM Brand

Founded in 1919, RM has built a strong reputation among professional body repairers worldwide. Its carefully formulated primers meet the highest industry standards, offering durability, ease of application, and increased workshop productivity.

Why Use a Primer?

Applying paint directly to a bare surface can cause poor adhesion, yellowing, or premature peeling. This results in an uneven film that compromises the quality of your work.
A primer provides a stable foundation that ensures:

• Enhanced adhesion for new paint layers

• Uniform color and long-lasting finish

• Fewer coats required, saving both time and money

When to Apply a Primer

A primer is essential when:

• The surface is porous, to prevent over-absorption

• The surface is too smooth, to improve adhesion

• The bodywork is new or unpainted

• You’re applying water-based paint over an old oil-based layer

• You’re performing a major color change

How to Choose the Right Primer

Your selection depends on three main factors: the existing color, the surface type, and the new paint.

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

• Oil-based primers: stronger odor and slower drying, but highly effective on challenging surfaces

• Color choice:

  • White or light gray for light paint shades

  • Black or dark gray for dark shades

Key Features of RM Primers

• Excellent adhesion even on smooth surfaces

• Improved strength and durability

• Long-lasting paint performance

• Effective masking of surface imperfections

• Reduced drying time for faster workflow

RM primers also help prevent:

• Paint peeling or discoloration

• Excessive layering

• Poor surface durability

How to Apply RM Primer

1. Use an aerosol can or a spray gun.

2. Clean and sand the surface thoroughly.

3. Spray evenly, keeping the proper distance between the nozzle and surface.

4. Apply the recommended number of coats uniformly.

5. Allow to dry, then sand lightly and clean again.

6. Once dry, apply your paint for a smooth, even finish.

Safety tips: always wear a mask and protective glasses, avoid eye contact, and work in a well-ventilated area.
