Product Description

Carbosol Metal Primer Spray is an anti corrosive metal primer paint for iron and steel, now available in an aerosol format. It is based on alkyd resin and contains modified zinc phosphate and binding pigments. This means that long term protection is provided (see below). It can be used with a variety of top coats so is a good choice for metal gates and doors, architectural iron work etc.

A choice of red, white, black, buff or grey gives you several options to match your topcoat. We have a variety of suitable topcoat paints for use with this rust inhibiting, anti corrosion primer. Take a look at our range of industrial and decorative top coats here and here.

  • Suitable for mild steel, carbon steel, stainless steel, cast and wrought iron
  • High in zinc phosphate for protection against corrosion
  • Drying Time: 15 minutes
  • Coverage: 2sqm per 400ml

About rust and corrosion:

Both iron and steel are prone to rust because they’re generally exposed to air and moisture. Rust forms when iron reacts with oxygen and water, it then creates a coating on the metal surface. When rust isn’t treated, the reaction (or oxidisation process) continues. This results in corrosion, which causes significant damage to metal (see HSE for more details).

A quality primer like Carboxide Metal Primer paint will provide longer term protection against rust and corrosion. Our customers say it works even when a surface has already begun to ‘ginger’ with rust.


Why does condensation form in my home?
Condensation forms more easily on cold surfaces in the home, for example walls and ceilings. In some cases, those surfaces can be made warmer by improving the thermal insulation. In many cases, thermal insulation is not possible due to house configuration or cost of refurbishment. An efficient way of combating condensation is to cover walls and ceilings with a specially formulated anti-condensation paint and TruTherm anti condensation paint has been formulated using the latest technology of additives.

What is the difference between anti condensation paint and thermal anti condensation paint?
Anti-condensation paint and thermal anti-condensation paint both aim to prevent condensation issues, but they work in slightly different ways:

Anti-Condensation Paint:
Purpose: Anti-condensation paint is designed to stop damp problems caused by moisture from inside the property.
Function: It creates a layer of insulation on surfaces, reducing the formation of water droplets on walls. This type of paint is particularly useful in areas prone to high humidity, such as bathrooms, kitchens, or basements.
Effect: By improving the thermal performance of surfaces, it makes them less likely to retain moisture, preventing condensation and mold formation.
Limitations: While it helps reduce condensation, it cannot completely prevent mold growth. Good air circulation, adequate heating, and ventilation are still essential12.
Thermal Anti-Condensation Paint:
Purpose: Like anti-condensation paint, thermal anti-condensation paint aims to prevent condensation, but it focuses on thermal insulation.
Function: It absorbs and holds heat longer than standard emulsions. By doing so, it prevents condensation from forming on the surface of the wall, as the heat evaporates any moisture.
Effect: The improved thermal properties keep the wall warmer, reducing the risk of condensation.
Application: Use it in areas where standard paints might struggle due to constant high humidity and moisture levels.
Note: While it helps prevent condensation, it’s essential to address root causes (such as ventilation and heating) alongside using this paint for optimal protection32.
In summary, both types of paint serve similar purposes but approach the problem from different angles. Consider your specific needs and the environment when choosing between them. Remember that no paint can completely eliminate mould growth, so proper maintenance and ventilation remain crucial.
