Painting is often hailed as the home improvement task that delivers the highest return on investment. A new layer of paint can transform a space, making it appear more vibrant, spacious (or cozier), or completely altering the look of your home’s exterior. Plus, it doesn’t require advanced skills or specialized tools to achieve.
However, just because painting is accessible to almost everyone doesn’t mean you should dive in without preparation. Hastily applying paint can lead to issues like peeling, bubbling, or unexplained stains within weeks, forcing you to redo the entire project. This turns a simple and cost-effective task into something far more time-consuming and expensive. To avoid these pitfalls, follow these essential steps.
Prepare the surfaces properly
The most certain way to ensure your paint job fails dramatically is by neglecting the preparation process. Properly preparing the surface you plan to paint is absolutely crucial. Here’s what you need to do:
Repair. If your walls have cracks, holes, or other imperfections, use joint compound to fix them. Any visible seams or loose drywall will remain noticeable after painting, and even if the paint initially hides them, they’ll eventually resurface.
Clean thoroughly. Before painting, wash your walls to remove dust, grease, dirt, and other contaminants. These can prevent the paint from adhering properly, leading to bubbling and peeling later. This is especially important for exterior walls, which are often much dirtier.
Check the weather conditions. Paint adheres best when humidity is moderate and temperatures are within a specific range—usually between 50 and 85 degrees Fahrenheit. Always refer to the instructions on the paint can. Extreme cold or heat and humidity increase the likelihood of paint failure.
Ensure the surface is dry. If you’re painting newly installed wood, such as a staircase or custom furniture, allow the wood to dry completely. Fresh lumber, even if it feels dry, often retains moisture, which can prevent proper paint adhesion. Pay special attention to knots, as they tend to retain more moisture and can cause bleeding through the paint. Patience is key to ensuring a long-lasting finish.
Apply primer. After cleaning and prepping, use an appropriate primer. For stained walls, opt for a stain-blocking primer. For raw drywall, choose a primer-sealer. In damp areas like bathrooms or spaces with water damage, consider mold-resistant or moisture-blocking primers. Primer creates a uniform surface, eliminating variations in texture and sheen that become obvious once paint is applied. This step is especially important when covering darker colors with lighter ones. (Note: While many paints claim to be “paint and primer in one,” a separate primer coat always yields better results.)
Select the appropriate materials
Using the right tools and materials is always more effective than cutting corners. High-quality paint may cost more, but it provides better coverage, durability, and requires fewer coats. Opting for the cheapest paint increases the risk of blistering, peeling, and discoloration. The same applies to tools—avoid the lowest-quality options. You don’t need top-tier professional gear, but steering clear of the cheapest options will significantly improve your results.
Invest in the correct roller for your project. The type of roller depends on the paint’s sheen (e.g., woven rollers work best with high-gloss paints) and the surface texture. Rougher surfaces require rollers with a deeper nap, while smoother surfaces benefit from a shallower nap, though this may require more frequent reloading of paint to avoid roller marks. Consulting a paint or hardware store expert can help you avoid issues after the paint dries.
Blend multiple gallons of paint together
To avoid uneven or mismatched colors, combine all your paint cans before starting. For smaller projects like a single wall or a small room, thorough mixing of one gallon is sufficient, especially if the paint has been stored for a few days. However, for larger spaces requiring multiple cans, pour them into a single container and mix thoroughly. Even cans of the same color can have slight pigment variations, and blending them ensures a consistent shade across the entire surface, preventing any noticeable differences in tone.
