Why Does Paint Have to Crackle?

Crack attacks are primarily caused by inadequate surface preparation. Cracking can also be triggered by over-thinning or applying paint too thinly. A heavy hand while painting, on the other hand, might cause muddy cracks, where too-thick paint cures with a crumbly, swollen image. Preventing insufficient drying time between coatings can potentially cause these complications. However, cracks can occur solely as a result of age. Paint becomes fragile over time, making it a little less adaptable to temperature changes and moisture. Similar problems must be treated as quickly as possible, not only to restore the painted surface but also to identify potential underlying issues. Keep reading to learn about the origins of common paint difficulties, as well as how to treat them and prevent future problems.

What are the Common Causes of Cracking Paint?

Cracking is caused by the splitting of a dry paint film from one or more layers of paint, whilst flaking develops when the paint is scraped from the foundation wall surface. These two causes, according to painting specialists, can arise for a number of reasons. When applying a coat of paint on your own, the simplest method to prevent paint failure is to use premium paint on a perfectly prepared dry surface. Unless you’re not confident you can handle it on your own, hire a reputable painting contractor.

Use of Low-Quality Paint

When it comes to painting, quality is important. A better-quality paint will give you maximum service – both long and short term – even if you’re looking at the interior or exterior paint, and whether you’re considering adhesion, durability, or hiding properties. Low-quality paint alleviates the ability of the paint to adhere to the surface which is often the common reason why the layer of paint cracks. 

In painting, the old adage “you get what you pay for” holds true. The lower the price of paint, the less likely it is to withstand the test of time. This could cause it to peel, crack, or chip more easily and quickly than a higher-quality paint. Make sure you do your homework before choosing your paint. It’s never a bad idea to do some research on a product, ask around, and read reviews. This will assist you in making an informed selection and also alert you to any potential issues that may arise in the future.

Exposure to Environmental Factors

Paint that has been applied to a damp surface or that has been exposed to high humidity is prone to peeling. Plywood, in particular, can expand and contract depending on humidity levels, causing surface coating fractures and cracking. Bubbling is one of the reasons for paint cracking or flaking. It has the tendency to shatter entirely after the paint bubbles. The excessive moisture, heat, or both causes paint to bubble. Make sure the wall is absolutely dry and cold before applying the first coat of paint. The paint will not apply well if the wall is moist or heated. Also, painting in a humid space or climate is not suggested. If you can’t avoid it, try painting at a more pleasant time of year or using a dehydrator.

Improper Preparation and Application

This is the most likely cause for the paint to fail, especially when using wood with a lot of flat hard grain. In addition, even with a thin layer of paint, if your paint surface is filthy or not primed properly, it’s prone to cracking and flaking.

What to Do When the Paint Cracks?

Remove the flaking paint with a scraper or wire brush if you know the cracking hasn’t gone all the way to the base. After that, sand the surface, fill up any bare places, and repaint. If the paint has cracked all the way back down to the base, you’ll have to remove it all. Scrape it all off or even use a heat gun to remove it completely. Then sand, prime, and repaint the surface. Because of so many variables and potential problems, hiring a professional to do your prepping and painting is often the better decision.
