Can I paint over rendered flooring?

jessgc

We've just moved into a new place, and it has this great flooring, which looks like tiles, but I think is a rendered finish. It's in the carport and up a ramp. While it's cool just like this, I thought it could be great to paint some of the shapes different colours so it has a Victorian tile effect.

However, I don't know what paint I'd need, or how well it would last? I'm assuming it would last better where there's only foot traffic, but it might wear down a bit more in the carport where the cars come and go. Any advice would be greatly appreciated!

These are the tiles...

And this is what I'm hoping to do...

Hello @jessgc 

Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your question about your carport flooring.

It sounds like you have a decorative rendered surface that mimics the look of tiles, which is a great feature. However, if there’s a seal over it, painting directly on top may not work, as the paint will not adhere properly. The challenge with sealed surfaces, especially on rough and uneven textures, is that it’s difficult to ensure complete removal of the sealer, which is necessary for good paint adhesion.

If you're set on painting it, the first step would be to test whether it's sealed by sprinkling some water on the surface. If the water beads up rather than soaking in, there's likely a sealer present. In that case, removing it would be necessary, but as I mentioned, the roughness could make this difficult. If you knew what sealer was used on the surface of the garage floor you could contact the manufacturer and ask them what stripper is compatible with the sealer used. You could then try to strip the surface of the carport. However, even with the best preparation, some residual sealer could remain, leading to adhesion issues.

If the surface is paintable, a high-quality paving paint such as White Knight Ultra Pave would provide extra longevity, especially in the carport. However, it will be necessary to verify with the paint maker if doing multiple coats in different colours over each other is possible.

If you have any other questions we can help with, please let us know.
