Berger Zinc Chromate Red Oxide Primer

Red oxide primer is a specially formulated coating used as a base coat for ferrous metals.

Berger Red oxide primer is formulated for interior and exterior use on ferrous metal and is not usually suitable for galvanized or nonferrous metals like aluminium, copper or brass. Ferrous metals contain iron. To confirm if your metal is ferrous or nonferrous, test it using a magnet. Ferrous metals are magnetic, and nonferrous metals are not. Berger Zinc Chromate Red oxide primer is an anti-corrosion coating, designed to stop rust formation. It can be applied directly over a rusty surface and is most ideal for exterior use. Red oxide primer can be coated with Berger 404, Rustpro or Machinery Enamel once dry.

For interior and exterior ferrous metal surfaces

Professional quality primer

For industrial use

Surface preparation:

Ensure that all substrates are clean and free from grease or oil
A clean surface ensures proper adhesion of the primer
Remove all loose and flaking material by scraping with a paint scraper, wire brush or by sanding
For some metals, flame cleaning or grit blasting may be necessary

Application Procedure:

When applying red oxide primer, use a brush or a short pile roller Thinning is not required if applying by brush or roller
For airless sprayer thin primer 10% to 15% by volume with Berger Reducer #2
Begin thinning with as little solvent and add more as needed until the right consistency is achieved
Spray red oxide primer onto the surface with a minimum working pressure of 2000 psi
Apply 1 coat to provide an adequate base coat to your metal
Touch dry 15 minutes. To handle 1 hour and recoat time 4 hours

Solve Potential Paint Problems

Reddish-brown stains on the paint surface are called nail head rusting and are usually a sign that the surrounding wood may be rotting.

What are the possible causes?

Non-galvanized iron nails exposed to moisture
Nails not properly countersunk
Nail heads not caulked with siliconized caulk before painting
Frequent exposure to damp wood

What is the solution?

Completely remove the nail and replace with a new nail
Wire brush each nail head until bare shiny metal
Clean and spot priming with appropriate Berger primer
Caulk nail heads with paintable Berger acrylic caulk
Topcoat with premium Berger acrylic or oil paint

Patchiness generally occurs when insufficient paint has been applied or when paint is applied unevenly, resulting in a variation of the film build leading to patches.

What are the possible causes?

Inconsistent distribution of paint on the surface
Incorrect or low quality paint brush or roller
Failure to apply a primer over joint compound
Applying paint over joint compound not fully dried
The top coat is applied over spot-puttied surfaces
Variations in surface gloss can cause paint to appear patchy

What is the solution?

Increase the amount of paint on the brush or roller to allow better distribution
Apply the paint in a grid fashion to ensure an even finish
Allow puttied wall to dry evenly before priming
By applying one coat of appropriate premium Berger Primer
Apply two coats of premium Berger acrylic topcoat

Poor hiding occurs when paint fails to obscure or hide the surface to which it is applied.

What are the possible causes?

Using low-quality paint with little hiding power
Spreading paint too thinly or unevenly
Over-thinning paint beyond the recommended amount
Failure to prime the surface before top-coating
Painting a porous or absorbent surface
Using incorrect or poor quality tools
Inadequately mixed paint

What is the solution?

Prime first, if moving from a significantly darker to a light colour
When painting in a dark colour, tint primer in a similar tone to the topcoat shade
Use premium quality paint for better hiding and flow
Use quality and correct tools for the job
Follow manufacturer’s recommendation for thinning
