Whether you're a seasoned painter or a DIY enthusiast tackling a home project, paint problems can pop up when you least expect them. Some issues are minor and easy to ignore, while others demand immediate attention to avoid bigger headaches down the line. Understanding the root cause of these problems can save you time, money, and frustration. Below, we’ve outlined the top five paint problems and practical solutions to help you achieve a flawless finish every time.
1. MILDEW: THE UNWANTED GUEST
Mildew is a common issue, especially in damp or humid areas like bathrooms and laundry rooms. But before you tackle it, make sure you’re dealing with mildew and not mold. Mildew is a surface fungus that’s less harmful than mold and easier to treat. To confirm, dab a small amount of household bleach on the affected area. If the stain lightens or disappears, it’s mildew.
How to Prevent Mildew:
Use high-quality, mildew-resistant paint.
Clean and sanitize surfaces thoroughly before painting, even if mildew isn’t visible.
Improve ventilation in moisture-prone areas by installing exhaust fans, dehumidifiers, or ceiling fans.
2. CRACKING AND FLAKING: THE SIGN OF POOR PREP
Cracks and flakes in your paint job aren’t just unsightly—they’re a sign that something went wrong during preparation. The most common culprit? Skipping essential steps like cleaning, sanding, or priming. Over time, these small cracks can grow, leading to larger flakes peeling off.
How to Avoid Cracking and Flaking:
Always prep surfaces properly by cleaning, sanding, and priming before painting.
Never paint over already cracked or flaking paint.
Allow each coat of paint to dry completely before applying the next.
3. LAP MARKS: THE TELLTALE SIGN OF UNEVEN PAINTING
Lap marks are those annoying streaks or darker patches that appear when wet paint overlaps with dry paint. They’re often caused by painting too slowly, working in direct sunlight, or applying paint unevenly. The good news? They’re preventable with the right techniques.
How to Prevent Lap Marks:
Always brush or roll from wet areas into dry ones for a seamless finish.
Use a primer or sealer on porous surfaces to ensure even paint absorption.
Work in manageable sections and maintain a consistent pace to avoid uneven application.
4. BLISTERING AND BUBBLING: THE RESULT OF HEAT AND MOISTURE
Blistering occurs when paint bubbles up, often due to heat, moisture, or improper application. Painting in direct sunlight, on hot surfaces, or over dirty areas can all lead to this frustrating issue. Blistering can also happen if you skip primer or mix incompatible paint types.
How to Prevent Blistering:
Address any moisture or heat issues before painting.
Stir paint thoroughly to ensure an even consistency.
Use slow, steady strokes to minimize air bubbles.
Stick to compatible paint formulas—latex over latex, oil over oil.
5. SURFACTANT LEACHING: THE MYSTERIOUS STAIN
Surfactant leaching is a common issue with latex paints, especially in humid conditions. Surfactants are water-soluble ingredients that can rise to the surface during the curing process, leaving behind a sticky or shiny residue. This is more likely to happen with deep-tinted paints or in areas with high moisture, like bathrooms or outdoor surfaces.
How to Fix Surfactant Leaching:
Avoid painting over stains or residues.
Rinse the affected area with water as soon as you notice the issue.
For exterior surfaces, let natural weathering take care of the stains over time.
