You should use both. Paint rollers are best for efficiently covering the large flat areas of a wall, while paintbrushes are necessary for precision work in corners, edges, and trim. Using both ensures a fast, even finish without leaving unsightly brush marks.
Do pro painters use rollers? Absolutely. Rollers are often used by professionals for their ability to deliver even coverage over large surfaces quickly.

Black, blue, and green: Darker shades like navy blue and hunter green feature intense pigments that can resist coverage, particularly by lighter colors. (If you've ever tried adding white paint over dark paint, you know how many coats you need for a solid finish!)
Key Points
Anything that needs to move like door hinges or locks, paint just gums them up. Radiators without the right paint can end up peeling. Tiles without proper prep and primer rarely last. Kitchen worktops are another one unless you're using the right system.
The 80/20 Rule in Art Practice
The 80/20 rule, or Pareto Principle, suggests that by spending just 20% of the usual time and concentrating on the crucial 20% of information, one can achieve 80% of the full painting's quality.
A neutral color palette for your base pieces is the way to go if you want to get that upscale look in your home. Beige tones, hues of white, and grey should be the colors of choice for your furniture, curtains, drapes, and other home accessories.
Unless you're wallpapering a wall, it's best to paint the skirting last to reduce the risk of your brush picking up dust or carpet fibres. For wood and metal surfaces, use Dulux Light+Space Quick Dry Satinwood, which features light-reflective particles to make your room feel spacious and bright.
The secret of how to paint straight lines between wall and ceiling is to use painter's tape. Run the tape along the edge of the ceiling to prevent any little drips or drops. When you take it away, you'll have a perfect line.
Preferably, early morning usually works best for interior and exterior painting. The temperatures are lower, and the paint has all day to dry. Avoid painting late in the day when dew may start to form because it will keep the paint tacky or not dry.
While it does take some setting up, painter's tape is the most effective way for painters to create straight lines. Whether cutting in or making an isolated line, painter's tape can create a straight line on almost any surface.
In these situations, some light cleaning may be necessary. Professional painters typically handle any wall washing needed as part of the preparation process before any paint is applied.
The golden ratio (also known as the golden section, and golden mean) is the ratio 1:0.62. Use it to divide lines and rectangles in an aesthetically pleasing way. In the above square A is 0.62 of the rectangle. Square B is 0.62 of square A.
Measure the wall and the art piece carefully. Consider the ⅔ rule as a general guideline: the artwork should take up approximately two-thirds of the wall space over your furniture.
The rule of thirds means that the subject isn't centered; rather, the main focal point can be to one side or at the top or bottom of the image. It's a tool to help artists draw the viewer's eye into the composition, rather than just glancing at the center.
Before putting brushes on a wall, here are some colors you may want to rethink before using them in your bedrooms:
The Designer-Favorite Color of 2026
“Clients are craving warmth, including taupes, sands, mushrooms, and creamy whites that feel cozy and timeless. Gray, once sleek and modern, now reads cold and flat; those warm neutrals wrap a space in calm and connection.”
1 Painter (DIY): Expect the job to take 8-12 hours for a full room, including prep. 2 Painters: Can cut painting time in half (4-6 hours), as one person preps while the other paints. 3+ Painters: With an assembly-line approach (one cuts in, another rolls), a room can be painted in 2-4 hours.
What Is the Hardest Wall Color To Paint Over? For many professional painters, red and black remain among the hardest wall colors to paint over because of their strong pigmentation and coverage challenges. However, yellow, navy blue, dark green, and glossy finishes can also create major repainting difficulties.
Wondering how long to wait between coats of paint? Generally, you can apply the next coat 2-4 hours after the first for water-based paints, while oil-based paints need a full 24 hours.
