Step two – sanding down. To sand a tub down, you can use either tools or sandpaper. By the end of this process, replace usual sandpaper by fine grit sandpaper, to avoid covering the tub surface with cracks.
Step three – degreasing. To put up a good show, it is necessary to clean a tub with solvent or purified gasoline. If you ignore this step, paint will peel off in a few months.
If the instructions on the enamel say to prepare it first, make sure you do it. Generally, surface of a bathtub and paint itself should be of indoor temperature.

- Wet paint should be applied with a natural brush – carefully and evenly. First coat is priming, and it takes 20-30 minutes to dry. Then you can apply the next one. Maximum number of coats is three.
You can start using a bathtub again in a week after painting. Before that, you should not only keep out of using a tub, but also watering the surface is not recommended.
