Hi there, I used Rust-Oleum Benchtop Transform Kit - Galaxy Black Bench Top Resurfacing Paint, which worked well. However, i have stains in one area. How can I fix it? Is redoing it the only way? If so, how would i do that? Thank you
Welcome to the Bunnings Workshop community @Kateryna. It's wonderful to have you join us, and many thanks for your question about painting a benchtop.
Is this a benchtop you've just coated or one you've done some time ago, which has developed stain marks?
Do you have any idea how the marks may have occurred? For example, do they look like roller marks, or do you think they may have been caused by something touching or sitting on the surface before it had fully cured? Knowing how they formed can help determine whether they are only in the top layer or if they go deeper into the coating.
If the marks are just in the surface layer, one option before committing to a full redo is to try polishing them out on a small, inconspicuous section. This can sometimes reduce or completely remove light surface blemishes. The process would involve very lightly wet-sanding, starting around 800 grit and gradually working your way up through 1200, 1500, and then 2000 grit. After that, you would typically use a cutting compound to refine the finish, followed by a polish to bring back the sheen. It’s important to go gently, as there is a risk that polishing can make the area more noticeable if you break through the coating or change the gloss level compared to the surrounding surface. If the marks are deeper than the surface layer, this method is unlikely to remove them.
As we stock the Rust-Oleum Home Countertop Kit Tint Base rather than the Benchtop Transform Kit, I’m not entirely familiar with the exact recoat process for the kit you used. With our kit, you would normally sand back and key the surface before applying a fresh top coat. For your specific product, it would be a good idea to contact Rust-Oleum directly or check the supplier to confirm the correct preparation and reapplication steps so you don’t risk compatibility issues.
If you do decide to recoat, I’d suggest trying the polishing approach first in a small area. If it improves the finish, you may save yourself a lot of extra work. If not, you’ll know a recoat is the more reliable path forward.
Please let me know if you have any questions.
