Painting is undoubtedly one of the quickest and least expensive ways to transform your home. It can update an area, hide flaws, highlight architectural detailsÂ and so much more. If you follow the 10 commandments of painting, youâre on the road to success. However, mistakes and problems do happen. If you encounter a hiccup, the painting experts explain how to fix it.
Fortunately, this type of blister doesnât hurt, but it can be painful to look at. âPaint blisters or bubbles occur when the paint film lifts from the underlying surface,â says Mike Mundwiller, Field Development Manager at Benjamin Moore.
So what causes a paint blister? âThe loss of adhesion between the paint film and surface is usually caused by heat, moisture or a combination of both,â Mundwiller says. And it eventually leads to peeling. While it can be corrected, he says you need to figure out whatâs causing the problem or it will occur again.
You can scrape and sand the blisters to remove them (if they donât go down to the substrate). Once the area is smooth, Mundwiller says you should apply a coat of primer and then apply the paint. âHowever, youâll need to find and remove the source of moisture if the blisters go down to the substrate.â
To stop paint from blistering or bubbling, Mundwiller says you should always start with a clean, dry surface. âApply primer-sealer over any stains and give it time to dry completely,â he says. “Always make sure that the paint is completely dry before you expose the surface to moisture,â Mundwiller adds. He also recommends using (or installing) exhaust fans or vents in high-humidity areas.Â
When you see a hairline crack, donât ignore it. âCracks in paint can start small, but will worsen over time if they are not fixed,â Mundwiller says. Cracks or flakes can be caused by a variety of issues, including not preparing the surface or applying oil-based paint over latex paint. âAlso, if you use a cheap paint, itâs not going to adhere properly or be flexible,â Mundwiller says. Sometimes, the paint is old, or itâs being applied in the wrong environment and, therefore, is drying too quickly.
âExtreme cracking, sometimes called âalligatoring,’ is caused when a second or third coat of paint is applied before the previous coat dries completely, or when the undercoat is incompatible with the finish coat,â he explains.
You can use a wire brush or scraper to remove loose paint (if the cracking isnât down to the substrate). âThen, sand the area to feather the edges, prime any bare spots and repaint the surface,â Mundwiller explains. You may need to use a filler if flaking happens in multiple layers of paint.
âIf the cracking goes down to the substrate, remove all of the paint by scraping or using a heat gun, sand the surface until smooth and even, prime, and then repaint with a quality latex paint,â Mundwiller says.
Colors are powerful and that’s why your color choices are important. But it’s also important to use the proper techniques when painting. A common mistake is spreading paint too thin, according to Jenny Burroughs, PPGÂ Paint Brand Senior Product Manager. âAlways ensure that your brush is evenly covered but not soaking wet, and follow the paint manufacturerâs instructions for application,â she says.
Sometimes, you donât need to paint a whole room, you just want to touch up a small area. âItâs not uncommon to see a noticeable difference in appearance between the original finish and the touched-up areas,â according to Mark Eichelberger, Senior Product Manager of Architectural Paint at Sherwin-Williams.
âTo avoid this, I recommend trying to clean marks with a soft sponge and liquid detergent before touching up,â he says. If itâs possible, he also recommends using the original batch of paint and a similar applicator to the one used in the original job.
Interior paint isn’t the only place you can run into issues, either. Staining a newly replaced deck can produce undesirable results. âPeople do not allow for proper curing time. Once cured, they also don’t know that they have to remove the mill glaze prior to staining,â says Michael Nungesser, Owner of Five Star Painting ofÂ Central Georgia and Fayette/Coweta.
âAllow 30 to 60 days for new boards to cure,â Nungesser advises. He says that most homeowners arenât aware that the new decking has a mill glaze (a glossy film that forms on the deck). The glaze can be removed with a wood deck cleaner, but Nungesser says this is another area prone to mistakes. âPeople often wash a deck with bleach and don’t neutralize the bleach with a wash prior to staining.â He also warns against using a pressure washer since it will impregnate the wood with water. For the best finish, he says to âallow the deck to dry to 20% moisture, and then apply two new coats of stain.â
