Although Soto's Premium All-In-One House Paint is durable enough to use on both interior and exterior surfaces (pretty much any surface will accept the coating), for best results, we recommend sticking to surfaces that do not have prolonged moisture contact or water submersion.
If you do use it on a surface with lengthy water exposure or submersion, the following will help give the best results:
First, prepare the surface by making sure it is clean of any debris (dust, rust, etc.). If there is any rust, you will definitely want to sand it away, and you may want to use a rust inhibitor on the bare metal. Vacuum and/or wash away any dust and debris, and thoroughly clean the area (our Shop Cleaner + Degreaser or our Multi-Surface Spray Cleaner works very well for this), and make sure it is dry before painting. Next, paint the area using several thin coats, making sure they dry in between. (The paint will likely dry to the touch in about half an hour, but it's best to wait 2-4 hours between coats, for optimum results.)
Full curing of the paint usually takes about 2-4 weeks, so it will be best if you can avoid exposing it to water until then. If that's not possible, you can temporarily cover the area with a waterproof covering (for example, by taping plastic wrap over the area) while it's in use, and then uncover it when you're done, to continue to cure.
