Don’t expect that you will never be able to paint with the paint again. All house maintenance work requires a certain level of maintenance.
Still, a ceramic coating can help protect your home from UV rays, and some swear it will help make a room a little more soundproof. The claim that this will cut your cooling costs by 30% or even 15% is controversial. Some researchers have said that the average savings are only 2%.
Some painters also say that the paint acts like a raincoat, making it difficult for water to get in. If the rain or moisture gets behind the paint, it can’t escape and can create a mountain of problems, including conditions that favor mold and rot.
My recommendation: don’t rely on paint to insulate your home. Blown loft and wall insulation keep your home cooler. I also suggest acrylic paint. It has greater elasticity than other paints, which minimizes cracks when the wall surface expands and contracts. It transfers the ambient moisture better so that the water is never trapped in the house and, if used correctly, lasts for five to ten years. In my experience, for whatever reason, homes in Arizona should never be painted with elastomeric paint. Ceramic paint isn’t worth the extra money, even around.
Q: Can I paint over cracked or damaged wood?
ON: If you paint bad wood with good paint, that paint won’t last a year. Before painting, check the siding, wood, or stucco for cracks, holes, water damage, and other problems. Repair them before painting. If you don’t, the paint will soon peel off and the underlying problem can lead to badly damaged or rotten wood. Go around your house twice a year to look for cracks in the siding and patch them up before they become major problems. Adjust the sprinklers so they don’t soak the wood or stucco parts of your home. Stucco is not a waterproof barrier.
