These problems can affect the health of your home by trapping moisture in places where it shouldn’t be. If you are considering painting the exterior of your home, you want to choose a paint that will hold up well even through frequent heavy rains.

Water-Based Exterior Paint

This category of paints includes latex paints and acrylics. These types of paints withstand moisture better than their oil-based counterparts. They don’t peel and crack as readily when moisture is an issue. Within this category, some types of paint are better suited to rainy areas than others. If you live in an area that is subject to a lot of moisture, choose latex paint with an acrylic binder. This type of paint is very resistant to moisture and it will look good for many years. Paints with vinyl-acrylic binders tend not to hold up quite as well as latex with an acrylic binder.

Water-based paints also have the ability to expand and contract with the surface on which they are painted. This means as your siding “breathes” during the year, you won’t need to worry about the paint cracking or peeling. Water-based paints also dry fast. Usually, they are dry within about six hours. When you are in a hurry, fast-drying paint is a bonus.

The Disadvantages of Oil-Based Paints

You can also paint the exterior of your home with an oil-based paint. However, these paints come with issues that you won’t have with water-based paints. Oil-based paints are not as durable on wood. They also do not hold up well with moisture.

Some homes have masonry on the bottom and generally this gets painted along with the siding. Oil-based paints have a tendency to discolor when applied over masonry. You could end up with a paint job you are not happy with if you are using an oil-based paint.

These paints also have an odor when they are fresh. The odor eventually wears off, but it can be irritating to some people. Another drawback with oil-based paint, it is hard to touch up. It has a tendency to fade faster than latex paint. This makes touch-ups nearly impossible if you want it to look nice with uniform color.

Solvents are used to thin oil-based paint and they are used to clean brushes. This makes using the paint more expensive than water-based paints. Another major consideration is that oil-based paints are flammable.

To their credit, oil-based paints work well on metal. They also resist stains, and on metal, they can resist chipping and mars. Walls painted with oil-based paints are easy to clean, though they can become shiny after a while with repeated cleaning. They also come in a variety of finishes.

When to Paint

Once you decide on your paint, you will want to choose a time when the weather is going to hold. Even though it is possible to paint in rainy weather, this is not something you want to do if it can be avoided. Your hard work will not pay off as well in the end if the siding is not dry and dull when you paint it. If it rains before you paint, generally you can paint once the siding feels dry. Morning rain doesn’t necessarily keep you from painting in the afternoon.

In an ideal situation, after a rainfall, you should wait at least four hours for drying time. That includes direct sunlight helping to dry the siding. If possible, wait a full work day before applying paint after a rain. If the nooks and crannies of the house are not dry when you begin painting, you may find water drips down the side when your brush touches those areas. This can leave light streaks and you’ll have to apply a second coat of paint to cover them up.

The “sidewalk test” is a rule of thumb by which many painters judge whether or not to begin painting. If the sidewalk is dry after a rainfall, then the siding is also dry and painting can begin. If it rains after you’ve painted, don’t worry. The eves and soffits block a lot of the rain that falls on the siding. Additionally paints dry faster now, so it is less likely that rain will cause a problem after the completion of a paint job.

Before beginning an exterior painting project – or any painting project for that matter, be sure to make the proper preparations. Old paint that’s peeling or chipped needs to be removed. These areas should be sanded down to create a smooth surface so the new paint won’t come up and allow moisture to get underneath. Make sure the surface you are going to paint is clean and dry. Prep time can often be the most labor-intensive part of the work.
