My patio floor needs refreshing. While at it, I'd like to avoid the boring gray and use a hint of color, either gray-blue or gray-green.
Here are the steps that I have planned:
- Lower the nails (by turning a little) to avoid that they rip the sanding paper.
- Sand the surface with grit 80-100 using a floor sander.
- Insert either the tip or the edge of a belt sander to sand the rounded edges, however far I can reach, with grit 120.
- Sand the top surface with grit 200-220 using a floor sander. Don't bother fine-sanding the rounded parts since even someone walking barefoot will not notice the difference.
- Apply one coat of "Low-Lustre Enamel Porch & Patio Floor Paint".
Do I have these steps right? Is there any surprise waiting for me?
One additional worry is that I will not even touch the (inaccessible) back side. Is there any chance that the planks would buckle from the different treatment after I'm done?
