Why does paint crack, bubble or peel?
Let me introduce you to Sisyphus, a deceiver, egocentric and narcissist. He was sentenced by Zeus for his mockery by having him endlessly roll a huge boulder up a steep only to have it roll back down. Roll. Sigh. Repeat. Many homeowners can relate to Sisyphus. Is it the right paint? What is the right temperature? Are the walls properly prepared? Many homeowners face this challenge. Let’s access the problem correctly.
When interior paints blister or crack, the trouble sometimes can be attributed to poor-quality paint, in most cases; the trouble is actually due to poor surface preparation or the wrong methods of paint application.
What are those little bubbles? That fresh coat of paint looks like the dimpled surface of the moon. Porous surfaces must be prepared first with a sealant or primer. Be patient! If you are full of energy and move to quickly for your paint, it will create those bubbles. Do not shake your paint, if you must mix it use a stick and stir slowly. Gloss-paint is especially sensitive. Take your time!
Those big bubbles were not there before? For your peace of mind, you are not just seeing things. Those blisters are usually seen on latex and acrylic interior and exterior finishes, they are an eye sore. They don’t happen immediately, but you will notice these when the paint separates from its base, in this case the temperature is to be blamed; if it is 35 degrees or below or 90 degrees or above. Another reason is having moisture on your walls, painting over a humid surface can often result in bulging blisters, make sure your walls are dry and allow any spackle or coat of paint to dry completely before you continue.
Why Does Paint Crack? Mud cracking. Paint was applied too thick, surface was not prepared properly, or dirt was not removed. Follow directions for appropriate preparation, spread out the paint evenly, make sure your walls are clean and free of any other residue.
Alligator cracks: Paint was applied over a glossy finish; application of a rigid coating like oil enamel over a softer and flexible coating, this is a no-no. Remove old paint first by scraping, sanding or using chemical removers, prep wash your walls and allow to dry. You’re welcome!
Hairline cracks: Applying paint to bare surfaces without the adequate preparation at first; over thinning or over spreading the paint. Prime surfaces before applying the paint; then apply the finishing coats at the recommended spreading rate.
Why Does Paint Peel? It is very simple; paint peels if it can not adhere to the underlying layer. The simplest solution is to sand. Sandpaper roughens the base surface, creating minute peaks and valleys onto which paint molecules can adhere to. Most paint peeling comes from moisture surfaces. The worse transgressor is paint incompatibility.
