Hardener RM

What You Need to Know About RM Hardeners

A paint hardener allows auto body professionals to achieve better protection of the paint and an optimal aesthetic finish. The RM brand offers reliable products that are easy to apply and suitable for bodywork exposed to weather conditions or matte finishes.

Easy to use, RM hardeners require no complex preparation, except in cases of rust. In such cases, it is recommended to treat the surface with an anti-rust product before application.

Who Is the RM Hardener For?

The RM hardener is primarily intended for auto body professionals. It can also be suitable for individuals wishing to protect the paint on their car, motorcycle, or bicycle. By choosing the RM brand, you opt for durable and aesthetic protection.

How to Use the RM Hardener?

  • Clean the surface to be treated
  • Degrease thoroughly
  • Derust if necessary

The paint + RM hardener mixture is applied using a spray gun. It is recommended to apply 2 to 3 coats, allowing a drying time of 15 minutes between each coat. The mixture remains active for about 2 hours, according to the technical data sheet.

How to Properly Dose Your Mixture?

  • Pour the amount of RM hardener into a clean container
  • Add 2 parts of paint to 1 part of hardener
  • Mix slowly and carefully until a homogeneous consistency is achieved

It is essential to follow the proportions and instructions mentioned in the product's technical data sheet to avoid finish defects.

Usage Precautions

  • Wear protective equipment: gloves, goggles, mask
  • Work in a ventilated and secure environment
  • Avoid any contact with skin and eyes
  • Do not inhale vapors and do not smoke during application
  • Wash your hands after use
  • Clean your equipment after use
  • Dispose of residues in suitable containers to respect the environment
