How to Avoid 6 Common Exterior Paint Problems
Even if you are not a professional painter by trade, you can still get great results when painting your home. Many of the problems that arise when painting are with the paint itself – specifically how it adheres, looks and endures. Here are some tips you can use for avoiding six common exterior paint problems.
Before you open the first can of paint, you’ll want to make sure all surfaces to be painted are clean, smooth and dry. For professional painters, this prep work often accounts for more than half the time they spend on a job. Good prep significantly reduces the likelihood of common paint problems.
Problem 1: Peeling
Paint can peel when applied to surfaces that weren’t dry during application or ones that became damp later as household moisture leaked through a wall. If you think moisture might be an ongoing issue, paint with the highest-quality latex paint you can find, and consider using a good primer coat to start.
Problem 2: Blistering
As with peeling paint, blistered paint is usually a surface-moisture problem. It also can happen when painting oil-based paint on top of latex as well as when applying paint in excessive air temperatures. Newly dried paint can blister if exposed to rain, so watch the weather forecasts when planning a job.
Problem 3: Wrinkling
The culprit here is usually paint that is too thick and that didn’t have sufficient time to dry. Cold weather also can cause paint to wrinkle. Even in “cool” weather, paint dries more slowly, so be sure to apply smooth, even coats and consider using two thinner coats rather than a single thick one.
Problem 4: Alligatoring
This is a painting term for when paint shrinks into little nubs that resemble the hide of an alligator. The problem can happen when paint doesn’t adhere well to the surface or when a second coat was applied over a still-damp first coat. Always give coats ample time to dry before coating over them.
Problem 5: Mold and mildew bleeding through
No paint on the market will mask and contain mold and mildew. These fungi need to be meticulously cleaned (killed) with a bleach-based cleaner, either one you concoct at home or one you buy. If you have a lot of mold, particularly inside your home, it’s not a bad idea to call in a certified mold inspector before doing any painting.
Problem 6: Lengthy drying times
The dry times listed on paint can labels apply to paint put on in optimal conditions and with proper techniques. Slow-drying paint is most often due to high levels of humidity in the air, coats that are too thick, or cheap (inexpensive) paint. Working on less-humid days, using good application techniques and buying the best paint will solve many issues with drying.
