- Roll-On Technique
To do the roll-on technique, first pour on some of the paint mix you’ve made into a roller paint tray. After that, you can now roll the pad on the roller and through the tray. Make sure that you are able to cover the pad evenly with paint.
Once you’ve put some paint to a tray, you can now apply the paint onto your hot tub’s interior. Start from bottom to top, and work your way into painting up to the rim. Make sure that your strokes are even and overlapping.
Once you’ve put in the first coat of paint, wait for it to completely dry before adding in another coating. Use a new roller pad and tray. Once you’re done putting in all the coatings, make sure that you let the coatings completely dry (this usually takes three days) before putting water again in your hot tub.
- The Brush-On Technique
For the brush-on technique, you can do the following steps:
Once you’ve made a paint mixture, dip your paintbrush into a paint bucket and apply the paint into the interior of your hot tub. To do this, you can follow and do it just like the roll-on technique, beginning from the floor and reaching towards the rim of your hot tub. Make sure that you apply the paint evenly and that the strokes are uniformly applied as well.
Put paint around the fixtures if desired, and let the paint dry for at least twenty four hours. After that, put in your second coating by using a second brush. Just like the roll-on technique, make sure that the paint has completely dried before refilling your hot tub with water again.
