What do you seal Corten steel with?

BROMOCO CT-7571. CT-7571 coating is suitable for all rusted metal and rusted mild steel projects. It is thick with anti-oxidants and works well with porous metals like naturally rusted metal, corten or other steels.

What is the best Corten sealer?

CT-7571 is the worlds longest lasting and most effective coating that protects Corten Weathering steel from continuing to corrode and weather. The coating protects steel from UV, oxidation, bleaches and acids to ensure the desired patina remains perfect for the lifetime of the coating.

Can you stop Corten steel from rusting?

You can prevent or control oxidation of Corten steel with the CT-7571. In this way, you can even create unique designs by mixing oxidised areas with unrusted, weakly rusted areas to which CT-7571 has been applied.

Can CT-7571-W seal rusted metal?

Yes, CT-7571 is made to protect rusty metals, and most rusty metals such as Corten steel and weathered steel require only one coat. CT-7571-W does not affect the original colour of the substrate and can be used to provide a glossy or satin finish to the surface as required. While the CT-7571-T offers deeper colours and vintage aesthetics.

Should I seal Corten steel?

Once the Corten steel has oxidised to your satisfaction, you can seal it with CT-7571 to prevent the Corten steel from continuing to oxidise. The use of CT-7571-W will not affect the original colour of the oxidised layer of Corten steel and will give Corten steel protection from physical damage, chemical attack and contaminants.

How do you accelerate rusting of Corten steel?

You can make rusting faster with the XL-08 Corten/Weathered Steel Accelerator. Corten/weathered steel often takes months to rust to the right degree in its natural environment, whereas the XL-08 cuts this process down to a few hours to a few days. This can greatly reduce the duration of the process and save time and cost.

How do you speed up weathering steel?

You can use the XL-08 Corten/Weathered Steel Accelerator to speed up rusting. We will provide you with precise operating instructions so that you can rust weathered steel safely and quickly. We also provide a professional team to evaluate and apply it at your home, and you can enjoy extra guarantee time.
