Primer spray Unimet SPRAY 400ML red (MPN MTP P 3009)

Unimet SPRAY 400ML red is an aerosol primer formulated to prepare surfaces for subsequent coatings. Supplied in a 400 ml spray can, this red undercoat promotes adhesion on metal, wood and previously painted substrates. It is intended for use as a preparatory layer that improves paint bonding and provides basic corrosion protection before applying finishing paints or lacquers.

Advantages

The primer offers a fast-drying aerosol format for convenient, even application on small to medium surfaces. Its red tint enhances visibility of coated areas during multi-stage painting work and helps identify missed spots. The formulation improves adhesion of topcoats and contributes to basic surface protection against moisture and early-stage corrosion when applied according to instructions.

Suitable for

• Preparation of metal surfaces prior to painting or finishing
• Priming wooden parts before applying topcoats
• Refreshing previously painted substrates to improve new paint adhesion
• Small repair and maintenance jobs, metalwork, hobby and DIY projects

When it may not be suitable

This aerosol primer is designed for general preparatory use and provides basic corrosion resistance; it is not a substitute for dedicated heavy-duty rust converters or long-term industrial corrosion protection systems. It may not be suitable for large-scale professional projects where thicker, brush- or spray-applied industrial primers and specific anti-corrosion treatments are required.

Key specifications

• Volume: 400 ml aerosol can
• Colour: red undercoat
• Intended substrates: metal, wood, painted surfaces
• Function: adhesion-promoting primer and basic corrosion protection
• Application method: spray application from aerosol

How to use

Ensure surfaces are clean, dry and free of grease, dust and loose rust or paint. Shake the can thoroughly before use and spray from the recommended distance in even passes to achieve a thin, uniform film. Allow adequate drying time between coats as indicated on the product label before applying finishing paints or lacquers. Work in a well-ventilated area and follow safety instructions on the packaging.

What to consider before purchase

• Confirm compatibility of the primer with the chosen topcoat (solvent- or water-based)
• Assess the size of the job to determine how many 400 ml cans are required
• Consider surface condition and prepare properly (degrease, remove loose rust/paint)
• Check drying time and temperature limits on the product label for your working conditions

Usage recommendations

For best results, apply light, overlapping passes rather than heavy single coats, allow full drying between primer and topcoat, and test a small area to verify adhesion and finish compatibility.
