Term: nap

In painting, "nap" refers to the length and texture of the fibers on a paint roller cover. It determines how much paint the roller can hold and how it applies the paint to a surface.

Key Points:

• Short nap (5mm–10mm): Best for smooth surfaces like plaster, ceilings, or timber. Provides a fine, even finish.
• Medium nap (10mm–15mm): Suitable for lightly textured surfaces such as painted brick or gyprock.
• Long nap (20mm+): Ideal for rough or heavily textured surfaces like brick, render, or concrete block. Holds more paint and reaches into crevices.

In Summary:

The nap is crucial in selecting the right roller for the job. Choosing the correct nap ensures better coverage, a smoother finish, and more efficient application.
