If you’ve ever picked up a brush thinking, “How hard could this be?”—you’re not alone. Many homeowners in Novi, MI take on painting projects with the best of intentions, only to find themselves frustrated by uneven finishes, weird shadows, or colors that just feel off.
Painting mistakes don’t always show up right away, either. Sometimes, it’s a few weeks later when the sheen starts to dull, or the corners begin to chip. And here’s the thing: most of these slip-ups aren’t because you’re not trying hard enough—it’s because no one talks about the small stuff that actually matters.
Whether you’re refreshing your kitchen cabinets, tackling a dusty bedroom wall, or painting your bathroom ceiling, even the tiniest detail can change the entire look. If you’ve already started a project or you’re prepping for one, this guide will walk you through what to avoid—and what the professional painters wish more homeowners knew from the start.
Key Takeaways:
- Skipping wall prep leads to poor paint adhesion and uneven color.
- Using the wrong paint type causes peeling, fading, or indoor air issues.
- Overloading brushes or rollers creates drips and patchy coverage.
- Exterior paint shouldn’t be used indoors due to higher VOCs.
- Test colors in natural light before committing to avoid regrets.
Avoid These Painting Mistakes That Could Ruin Your Project
Painting your home should feel exciting, not stressful. But many efforts go sideways because of simple yet avoidable painting mistakes. From skipping prep to picking the wrong paint sheen, these errors can turn a fresh start into a frustrating mess.
We’re breaking down the most common painting mistakes we see in homes across the area—and sharing expert-backed tips to help you get it right the first time.
1. Rushing to Pick a Paint Color
Choosing paint seems fun until you’re standing in the aisle surrounded by 200 shades of “white.” Most painting mistakes start here—picking a color based on a paper swatch or a picture online.
The truth is, color behaves differently depending on light, shadows, and even the type of primer you use underneath. What looks fresh and modern in your kitchen might feel flat or dull in your living room once the daylight fades.
Try this instead:
- Sample two or three shades of the color you like.
- Paint swatches on the wall (or on paper) and check them at different times of day.
- Think about nearby furniture, floor, and how much natural light your room gets.
2. Not Prepping the Surface (Yes, You Have to)
One of the most common painting mistakes? Skipping prep. Even if your drywall looks clean, it likely has a layer of dust, grease, or moisture that can ruin adhesion.
Peeling, bubbling, and uneven texture usually come from not cleaning, sanding, or priming before painting.
What proper prep looks like:
- Clean the walls with mild soap and water. Let them dry fully.
- Patch any small holes or cracks with spackling compound, then use sandpaper to smooth.
- Apply the right primer. A quality base helps your paint stick better and show its true color.

3. Using the Wrong Type of Paint
Not all paint is the same, and using the wrong kind in the wrong space is a classic painting mistake. A high-gloss acrylic paint might look sharp on kitchen cabinetry but will be far too shiny for a cozy bedroom wall.
Here’s a quick breakdown of what goes where:
- Flat or matte finishes: Great for low-traffic areas and ceilings. Hides imperfections.
- Satin or eggshell: Ideal for living rooms, bedrooms, or hallways.
- Semi-gloss or gloss: Perfect for trim, baseboards, and bathroom walls where moisture is a factor.

4. Skipping Tape and Relying on a Steady Hand
You might think you’ve got a steady hand, but unless you paint daily, don’t risk it. Not taping off your windows, trim, or baseboards leads to a sloppy finish and unnecessary touch-ups.
Tools that actually help:
- Quality painter’s tape (not masking tape)
- A clean paintbrush with tight bristles
- Angled brushes for cutting into corners or around cabinetry
If you’re trying to save time, taping feels like a drag—but it’s way faster than fixing uneven edges later.
5. Painting in the Wrong Temperature or Humidity
In Novi, MI, where weather swings between humid summers and dry winters, the room’s climate can ruin your paint job.
Painting mistakes related to temperature include slow drying, streaky coats, or even blistering. If the room is too humid, especially in a bathroom or kitchen, moisture can seep into the wood or drywall and wreck adhesion.
Watch for these conditions:
- Ideal temp range: 50°F to 85°F
- Low humidity days are better for drying
- Always ventilate the room, especially when using oil paint

6. Overloading the Brush or Roller
Paint dripping down your walls, or visible texture you didn’t want? That’s often from applying too much paint at once. Overloading your brush, roller, or sprayer can waste paint and create uneven coats.
Tips from the pros:
- Dip your paintbrush about a third into the paint, not all the way.
- Use a tray to roll off excess paint before it hits the wall.
- Go with multiple light coats rather than one thick one.
This applies even more when using spray painting tools—technique matters to avoid spattering or overspray.
7. Using Exterior Paint Indoors (Yes, It Happens)
Believe it or not, some DIYers grab exterior paint for indoor use, especially when they’re looking for durability. While it might sound smart, this is one of the bigger painting mistakes you can make.
Exterior formulas often contain higher VOCs, which can affect air quality and even cause headaches in closed indoor spaces.

8. Not Knowing How Much Paint You Need
Running out of paint mid-job is frustrating. Buying too much wastes money. Estimating the right amount can be tricky if you’re covering textured walls or switching from dark to light colors.
A lot of it depends on the surface, type of primer, and number of coats. If you’re unsure, plug your room details into our paint calculator to get a more accurate guess.
