Does Size Matter?: Picking the Right Paint-Roller Nap

Paint roller covers are made for particular surfaces. Smooth surfaces require a thinner roller nap whereas rough surfaces require a thicker roller nap. Choosing correctly will determine the success of your paint job.

Do you want to paint like a pro? Well it is important to choose the right roller cover. What a lot of people don't know, is that choosing the right roller cover is just as important as choosing the right paint colour. You didn't know that either? That’s okay, you're about to find out why. Firstly, remember to examine your surface texture beforehand. The smoother the surface texture, the thinner the roller nap should be; so let's say you're painting drywall, you should use a 1/4 –inch or a 3/8-inch, these are quite thin and are best suited for smooth surfaces. On the other hand if you’re painting stucco or brick which are quite rough, you will need to use a thicker roller nap, a 1/2-inch or a 3/4-inch will do the job. It will take you a very long time to finish painting a rough surface with a short roller, it may even be impossible to finish the job, and if you use a thick roller cover on a smooth surface it will produce a lumpy and unacceptable paint job. And who has the time for that disappointment, right?

Natural vs. Synthetic

The material that a paint-roller cover is made from has a huge effect on the finished result of a paint job. So when you're choosing, go for a high quality polyester or nylon cover. Both can be used with latex or oil-based paints. Roller covers made from natural fibers, such as sheepskin, woven wool and mohair are also available.

Foam roller naps work great when used with latex paints, as they are made for a thinner paint. They should be used to apply smooth coats of paint on very smooth surfaces. The uniform thickness of the foam means that they aren’t the best choice for rough surfaces. Foam rollers are sometimes considered one use rollers.

Note: For each roller nap you’ll need a roller handle to attach, what you need to remember is to choose one with a space for another fitting to be inserted (female fitting), this will allow you to attach an extension pole that will help you to move faster, whether you're painting walls, ceilings or floors. You're ready to make that purchase, and you’re ready to start painting!
