Boysen Red Oxide Metal Primer B310 – 4L

Description

Preparing steel or iron for a protective paint system? Boysen Red Oxide Metal Primer B310 is the primer stage of the job. This listing supplies one 4L can; the final coloured topcoat is ordered separately.

At a glance

Coverage and project timing

Boysen’s theoretical coverage is 25–30 m² per 4L at 2.5–2.0 mils dry-film thickness, depending on texture and porosity. Use it as a reference for one primer application. Budget the topcoat separately and allow the stated recoating interval; a surface that feels dry to touch is not automatically ready for the next coat.

Topcoat compatibility

The manufacturer’s schedule lists Quick Drying Enamel, Cool Shades or Roofgard for the second and third coats. Follow the appropriate preparation and thinning guidance on the label. Selecting a compatible finish is part of the order, so include the topcoat name when asking us to check your shopping list.

Before ordering for gates or metalwork

Tell us the metal type, whether it is bare or painted, and how much corrosion or loose coating is present. Send a close-up photo and measured coating area; include both sides when both will be painted. Different metal conditions need different preparation decisions. Brushes or rollers, surface-preparation tools, tape and thinner can be added as separate order lines.

What is included

One 4L container of Boysen Red Oxide Metal Primer B310. Primers, putty, reducers and painting tools are separate purchases unless expressly listed in your order.
