Primer spray Bardahl Grå Primer 400 ml — Bardahl 64004, gray aerosol primer for surface preparation

Bardahl Grå Primer Spray 400 ml is a gray aerosol primer formulated to prepare and optimize surfaces prior to painting. The product creates a uniform priming layer that improves adhesion of subsequent topcoats, reduces the risk of corrosion on metal substrates and evens out minor surface imperfections. Packaged in a 400 ml spray can, it is suitable for targeted application in automotive refinishing, repair tasks and general maintenance where a consistent base coat is required.

Advantages

This gray primer provides good adhesion to metal and commonly used substrates, helping subsequent paints to bond more reliably. The aerosol format enables controlled, even application and quick drying compared with conventional brush-on primers. Its corrosion-inhibiting properties help protect treated surfaces during storage and assembly until the topcoat is applied. The neutral gray color gives a consistent and practical base that reduces the number of topcoat layers needed for full coverage.

Suitable for

• Automotive bodywork preparation and spot repairs
• Metal parts and equipment maintenance before painting
• Small to medium-sized repair and refinishing projects
• Preparation of surfaces prior to applying lacquer or enamel topcoats

Key specifications

• Form: aerosol spray, 400 ml can
• Color: gray primer
• Function: adhesion promotion and surface priming
• Substrates: suitable for metal and commonly painted surfaces
• Drying: fast-drying aerosol formulation (drying time depends on ambient conditions)

How to use

Ensure the surface is clean, dry and free of rust, grease and loose paint before application. Shake the can thoroughly for the time indicated on the label to homogenize the contents. Apply in thin, even coats from a suitable distance, allowing brief flash-off time between passes to avoid runs and ensure an even layer. Allow the primer to dry fully according to ambient temperature and humidity before sanding lightly if necessary and applying the chosen topcoat.

Usage recommendations

Use in a well-ventilated area and follow all safety instructions on the packaging. For best results, test on a small area to check compatibility with the intended topcoat and substrate. Store upright in a cool, dry place away from heat sources and direct sunlight.
