What is the best exterior paint for rain?

For most exterior painting jobs, water-based paint is the best exterior paint for rain. This category of paints includes acrylic and latex paints but doesn’t include oil-based alkyd paints. Water-based paints don’t trap moisture beneath them, which means they are less likely to crack, peel, or become discolored like oil-based paints when exposed to the elements.

If you’re looking for exterior paint that can withstand regular heavy rain and continue to look fantastic for years to come, choose a latex paint with an acrylic binder. This type of paint has better weather resistance than paint with a vinyl-acrylic binder.

In addition to being highly resistant to rain damage, water-based paints have the advantage that they expand and contract with the siding on your home, which can reduce cracking. This type of paint is also relatively quick drying, taking up to six hours to completely dry, compared to the much longer drying time of oil-based paint.

Oil-based alkyd paint is the best choice for metals that rust, as it can protect them from moisture. However, on other surfaces, such as wood, it is less durable and weather-resistant than water-based paint.

If you are painting wood that has never been painted or stained before, you will need to prime the surface to protect it from the weather prior to painting. If you plan to use water-based paint, you can use a water-based or an oil-based primer. However, water-based primers aren’t suitable for use under oil-based paint. After applying the primer, wait until it is completely dry before you apply your chosen exterior paint.

Finally, you should never try to apply exterior paint in the rain or when rain is in the forecast. Rain can wash away paint while it is still drying, leading to a streaky appearance.
