Spending more time at home because of the pandemic has spurred on countless home owners to embark on their home improvement journeys. From repainting projects to furniture DIYs, there are endless ideas on how to make your house truly a home. With the onset of the rainy season though, you’ve probably noticed some extra set of items that need to be ticked off your list as well. This can include leaky roofs, some paint failures, and of course, rusting. Rust starts off small. A seemingly harmless patch of brown on a far corner of your gate, roof, or metal railing. But, if left unchecked, it can spread out in no time. This is where BOYSEN Rust-Off comes in. 

What is BOYSEN Rust-Off?

BOYSEN Rust-Off is an alkyd-based metal primer that is used for interior and exterior steel and iron surfaces. If you’ve got any metal doors, beams, framings, and railings, you can use Rust-Off on these! As the name implies, it inhibits rust in these metal substrates. However, it can be used as an intermediate coat as well.

Product in Focus: BOYSEN Rust-Off | MyBoysen

Why should you consider Boysen Rust-Off as a metal primer for your upcoming projects? Developed with special rust-inhibiting pigments, it’s even more corrosion-resistant than traditional metal primers. It’s also available in a light gray shade that offers optimal coverage over colored substrates. It makes it easier for you to pick your topcoat color of choice! Last, but not the least, you can rest easy knowing that this product is also formulated without any harmful, heavy metals such as lead and chromate.

Surface Preparation

Always wipe the surface with a clean rag soaked in paint thinner prior to painting to remove grease, oil, and wax. If the substrate to be repainted is still in good condition (no significant paint defects), you can just sand the surface lightly to promote adhesion of paint onto surface. Make sure to clean the surface again after sanding. Surface to be painted already rusty and corroded? Thoroughly remove any existing rust by using a wire brush. Use BOYSEN Metal Etching Solution B-71 on the brushed surface and leave the solution on the surface for about 10 to 15 minutes. Afterwards, wipe off any remaining residue from the surface and immediately prime the surface after letting it dry.

How to use Boysen Rust-Off

Product Highlight: BOYSEN Rust-Off | MyBoysen

Boysen Rust-Off can be used as a primer for painting various metal substrates such as roofs, floorings, and other metal substrates like gates and beams. Its application is quite simple too. You can just use a regular brush or roller to get the job done. However, you have to wait for around 8 to 12 hours for the product to fully cure. Make sure to follow this recommended drying time before you apply two coats of a topcoat to ensure the best results!

For roofing systems, paint one layer of Boysen Rust-Off  then you can use either Boysen Roofgard or our heat-reflecting roof paint, BOYSEN Cool Shades, as a topcoat. In case you have some metal floorings like in exterior walkways or garages, use BOYSEN Acqua Epoxy as your topcoat after applying Boysen Rust-Off. For other areas such as gates, doors, and beams, use Boysen Quick Drying Enamel as your topcoat. All of these are available in several colors for you to choose from!

Some Final Thoughts

Rusting is no small matter. It starts off in one small corner of your gate or roof and the next thing you know it’s all over the place! It corrodes and weakens metal substrates that can lead to leaky roofs and faulty gates. Make sure to nip it in the bud before it has a chance to settle in by using BOYSEN Rust-Off as your metal primer. Do you have any other question on the product or how to use it?
