Finally, if you are painting a piece of furniture exposed to the elements, use an outdoor sealant or varnish. This will help to protect the paint from fading in direct sunlight and provide a watertight finish that can withstand inclement weather.

How Long Will Waterproofed Chalk Paint Last Outside?

The longevity of waterproofed chalk paint used outdoors depends on the environmental conditions it’s exposed to. Generally, a good quality waterproofing sealant lasts 1-3 years in most climates.

However, if the area is more exposed to harsh weather conditions such as extreme sunlight or heavy rain, the paint may last for a shorter time.

It is important to consider your area’s climate before deciding whether waterproofed chalk paint is a good option for your outdoor project.

Applying a fresh coat of waterproofing sealant each year may be beneficial to ensure the optimal longevity of your waterproofed chalk paint job outdoors.

Does Chalk Paint Come Off with Water?

If these methods don’t work, you may have to use harsher chemicals to remove the paint. However, take all necessary safety precautions and wear protective gear when using chemicals, which can be hazardous to your health.
