As mentioned, thick layers of paint can lead to longer drying times. Stick to thin, consistent layers to optimize drying and promote an overall better finish.

Finishing Touches

Once your Rustoleum spray paint project has fully cured, it’s essential to take a few extra steps to finish it off properly:

1. Sealing

If your project is outdoors or subject to wear and tear, consider applying a sealant to add another layer of protection. This step can prolong the longevity of your paint job.

2. Regular Maintenance

After applying Rustoleum paint, regular maintenance can further ensure your project remains vibrant and intact. Clean the surface gently and inspect for any signs of wear.
