Roller and brush for walls: choosing the right tool for the surface
Good paint cannot compensate for the wrong roller. Surface, texture, and application method directly affect how even the coat looks.

The rougher the surface, the longer the nap
Smooth walls usually use a shorter nap for a neat texture. On rough, porous, or textured surfaces, a longer nap carries paint into recesses more effectively. Check the exact recommendation for the product and substrate.
A brush complements a roller rather than replacing it
An angled brush is convenient for cutting in along ceilings, corners, trim, and places a roller cannot reach. A roller covers the main wall area faster and more evenly.
A properly loaded roller should not drip
The roller should be evenly loaded with paint but not drip when moved. Heavy pressure on the wall is usually unnecessary and can create uneven texture or force paint out at the roller edges.
Maintain a wet edge
Work in manageable sections and join fresh areas before the previous edge begins to dry. This reduces the risk of visible bands and lap marks.
