How Long To Wait To Paint After Washing Exterior? Let’s Discuss The Whole Chemistry

It is mentioned earlier that you need to wait 24 hours to 3 or 4 days to start exterior painting after washing.

Then you can decide to start painting the exterior of your house. It is never a good idea to paint the wet surfaces after washing.

For example: the wet woods under the siding begin to bubble during painting. But when the whole exterior with siding dries properly, the painting will be great and stable.

If you are a beginner, in this case, you should contact a professional service to avoid any damage to your house’s exterior.

They also know how to prepare your house’s exterior and how long you should stay quiet before you start painting.

If you have a better experience with pressure washing and painting and want to do it, you have to consider some factors.

Some significant facts determine the time needed for a home’s exterior painting after washing. Some of them have been discussed below:

1. Effects of Exterior Environment

The main fact will speak out how long after washing the house’s exterior you can paint the atmosphere of the home.

You have to give time to your house for drying can differ for several areas and other atmospheric conditions. It includes two most important parts:

● Effect of Temperature

The temperature of the house exterior has much to do with the drying variety. The high temperatures can dry the exterior very quickly.

According to science and experts, “The heat plays a vital role to vanish the wetness of the walls of exteriors because of the higher speed of the molecules and as a result, dries it out.”

Air circulation is another matter that performs very well in drying out the exterior walls quickly. This circulating air vanishes the moisturizer from the walls and helps dry.

● Effect of Humidity

Humidity is the most responsible for taking more time to dry the exterior. It affects the situation by linking water to moderately dried paint.

This condition makes the places complicated to dry. Plus, the recent moisturizer in the present air makes it more difficult for the water on the exterior’s walls to dry.

2. Weather Condition

Most timing of drying the house exterior depends on the weather condition. The exterior will be difficult to dry, especially in the rainy season. The humidity or cold temperature can affect the drying time between washing and painting.

In the rainy season, the atmosphere adds extra moisturizer into the air that hinders and takes a longer time to dry the wet surfaces.

So, when you try the pressure washing in this weather condition, you just wish for a bad result. For this reason, I suggest waiting for the dryer weather for exterior painting.

3. About Paints

The types of paint are also important for exterior painting after power or pressure washing. If you wash the exterior of your house on a rain-free and sunny day, you can choose Multi-purpose Premium Latex Based Paint.

If you love to apply oil-based paints, you should take the time that we recommend above. Wait for drying fully from the base of every single item of your house exterior and start painting.

4. House Position

If your house is located in an open area and it is a sunny day, the drying time will be shorter than in a shaded area.

When several houses stay around your ones and have more shadows of trees, you have to wait more than 48 hours after washing. A sun-facing house takes a shorter time than a house under shade.

Hence, evaluate the above factors and decide how long you need to start painting the exterior after washing.

How Long Should You Wait For Siding Dry Before Painting The Exterior?

You should leave the siding of wood to dry for 24 to 48 hours under the sunlight or in hot weather. Before starting your painting, it is most necessary to check the sides of the woods of your deck. You can start if you think they have dried and are ideal for painting.

What Will Happen If You Start Painting On The Walls Without Fully Drying Them?

A bumpy, unsaturated, and patchy look of the exterior walls after the painting is the worst result of painting on damp walls. You will also notice the paint peeling off the walls soon after completing your painting.

So, I recommend waiting for days before painting your exterior surfaces so that the whole area can settle the texture properly. It dries your walls perfectly and helps you make a nice look again.

Always remember that your efforts, like washing, rinsing the extra detergent, and painting, can be ruined if you don’t let time dry the exterior surface.

When they dry completely, you can achieve bright and saturated paint on your house exterior. Any type of painting application is ideal after a time when the washed areas form a clean, smooth texture that is also stain-free.

Should House Exterior Be Washed Before Painting?

Yes, you must take the step of pressure washing or power washing your whole exterior before painting.

It helps the new coat of paint to link with the exteriors properly. The washing makes sure the painting is stable and long-lasting every time.

If you need to prepare our house for any large family occasion, party, family gathering, or selling, you need to prepare your house from the exterior.

Believe it, coating paint to make it look new and fresh washing is important before painting.

Why Do You Need to Pressure Wash Before Painting the Exterior House?

There is no denying the importance of pressure wash before painting the exterior. It cleans the whole house’s exterior surface altogether.

It eliminates the filth, grime, peeling, and even loose paint from every corner. It helps to touch the coat of paint on the surface properly and expand the life of the painting.

That’s why, for the best result, you should consult a professional pressure washing company that makes your task effective and easier. Or my personal opinion for you, if want to pressure wash by yourself then can purchase an electric pressure washer. It will save your money and time!

Final Thoughts!

Yes, it was critical to answer correctly on how long to wait to paint after washing the exterior? But my good research and analysis make it easy for me to understand that it mainly depends on a variety of things.

It also can be measured between the sun-facing and shade situation of your exteriors. I hope you have got your answer through this post.
