How long does paint last on walls?

Hi Karishma, I am here to answer your question regarding how long does interior paint last on the wall. The average range is 5 to 10 years for paints. However, when maintained well, paints can last up to 15 years, too. I guess it will help if I tell you about ways through which you can improve the life of your wall paints.

How Long Does Paint Last on Walls?

Here are some techniques you can use to improve the paint’s life.

1. Choose colours with fade-resistant pigments. This helps give freshness to the wall paint and increases its life, even against exposure to the sun. This technique works well for exterior paint, where exposure to the sun for long periods leads to discolouration. 

2. You should use appropriate paint for high-traffic regions. I advise a paint that can withstand extensive cleaning while retaining its colour. Doing so will keep the look of the walls fresh even with a lot of human traffic.

3. The last thing I have in my bucket is running an inspection at regular intervals. For exterior walls, you can apply a weather coat every 3-5 years. For the interiors, you can choose the same duration and run the necessary checks.

This is all I have to share. I hope you now know how long does wall paint lasts. 

Applying a fresh layer of paint to the exterior or interior walls can be expensive. So, to avoid repainting your house over and over again, you may think ‘how long does paint last on walls?’ 

There are several factors which decide how long does interior paint last outside. Some of the points include:

• Quality of the paint- Most paint comes with a guarantee. There are different types of paint that can be used such as oil paint, eggshell paint, acrylic paint, etc.  It would be a good choice if you use acrylic paint to paint your house. Again using oil paint is not a wise option since oil paint takes a long time to dry and it can get peeled off after a few months.

• Weather- Humidity, sunlight, and rain play a very important role in painting. A fresh layer of paint can chip off due to dampness. 

• Maintenance- Painting is not an easy job. It takes a lot of effort to paint a wall. Sandpaper and primer should be used properly. Also, the wall should be clean before painting a wall. Or else, the painting can damage the wall and it won't last.

• For interiors, washable paints should be used so that the wall can be cleaned periodically.  If you see paint is peeling or showing signs of dampness you should take measures to repair the portion immediately. 

After taking these measures a good quality paint for exterior can last up to 7 to 10 years and for interiors, it can last up to 5 to 10 years.
