How to Choose a Roller Cover


The best roller cover for your project will depend on both the size, smoothness and desired appearance of your painting surface. Keep these features in mind when choosing roller covers, and don’t forget a roller frame to go along with it.

Roller Cover Fabric Determines productivity and final appearance.

Choose woven roller covers for a smooth, lint-free finish.

> WhiteDove™, Ultra Finish®, Colossus™, Parrot™

Choose knitted roller covers for fast application and increased productivity

> Marathon®, GoldenEagle™, Contractor 1st™, Roadrunner™

Nap Size Depends on surface and desired smoothness.

The smoother your surface, the shorter the roller cover nap should be. This will ensure a smooth even, finish. Use larger nap sizes fo rougher surfaces to ensure good coverage.

1/4" Nap — very smooth to smooth surfaces, like cabinets, metal doors and trim.

3/8" Nap — smooth to semi-smooth surfaces, like smooth walls and ceilings.

1/2" Nap — semi-smooth to semi-rough surfaces like textured walls, decks and concrete.

3 / 4 " Nap —  semi-rough to rough surfaces, like textured ceilings and stucco.

1"+ Nap — rough to extra-rough surfaces like brick, masonry block and textured concrete.

Roller Cover Size Choosing from a variety of sizes from 4" to 18".

The longer in length your roller, the more surface area you can paint, with shorter rollers ideal for edges and corners. Choose your roller cover based on how much area you need to paint. Keep in mind you may need a brush to finish the finer details.

When choosing a mini roller to reach tight spots, match fabric and nap size for a seamless finish.
