In reply to Mike ridge. Hi Mike. You can apply a second coat. You need to wait a minimum of 6 hours and no more than 48.

Can I apply a second coat of rustoleum floor primer over the first and is there a timeline to do so?

In reply to Walter. Hello Walter. Once you pass the 48 hour window, you need to rough up the surface with 120-150 grit sandpaper before applying a color coat of paint or epoxy.

Hello, I applied one coat of Rustoleum Recoat Primer to garage floor but I have waited several days and not yet applied any topcoat not realizing that I needed to apply topcoat no longer than 48 hours. What do I do now? Thanks

In reply to John Carr. Hi John. No, the Rust-Oleum Recoat Primer is not formulated for application to bare concrete. If the remaining paint that is adhered well was roughed up with the grinding, then the surface is sufficient for direct application of the epoxy. Keep in mind that you will want to reduce your coverage rate by 10-15% since the bare concrete treated via grinding will absorb more of the coating (good thing).

I have an old garage floor. It has been painted a few times and some of the paint was peeling. I was able to grind 75% of the paint down to bare concrete. Should I prime with recoat primer considering there is still some paint in some places ? I want to paint with epoxy shield.

Thanks,
John
