Quality paint roller covers consist of seamless plastic or phenolic cores that are moisture resistant and constructed with glue that withstands solvents in paint. Covers of polypropylene can have the nap attached to the core through thermal fusion. This is sometimes referred to as flame bonding. A phenolic roller cover is useful for a variety of applications. It is advantageous to use one core for latex and another core for solvent based coatings. At Pro Roller Company, Inc., we provide our customers with a range of different paint roller options to help them achieve superb results.
Features to Avoid in Paint Rollers
Some of the features to avoid with paint rollers include foam rollers that leave a cratered finish as a result of air bubbles. Covers that have untreated cardboard cores which tend to lose their shape when exposed to moisture for a period of time are also undesirable. It is best to avoid covers that leave lint or roller marks on the walls you are painting.
Determining Your Preferable Nap Length
The nap length of your phenolic roller cover should be dictated by the nature of your project. If you are putting eggshell or matte paint and drywall that’s previously been painted, a 5/16 or 3/8 inch nap will carry a considerable amount of paint while texturing the surface marginally. If you are painting a smooth surface with high sheen paint or new drywall, a 3/16 or ¼ inch nap will deliver the smoothest finish. Most walls and paints work well with a 3/8 inch nap, provided a high quality roller is used. A 1/2 inch nap works well on any previously painted, textured surface or medium textured plaster. If you are painting concrete block or other rough surfaces, a 3/4 inch nap or larger will work best.
Nap Density and Covers
Regardless of whether you are working with a phenolic roller cover or other type of roller cover, the density of the nap is also important. The higher the nap density, the higher quantity of paint it can hold without splashing and also providing an even finish. Splatter can be minimized by steady, slow rolling action or with the use of a roller shield. Sheepskin and lambswool covers have the necessary density to carry a significant amount of paint and produce excellent results on textured walls. Lambswool, will not work that well with latex, does very well with alkyd paints. Mohair or microfiber covers apply paint evenly to smooth surfaces. Artificial fibers perform well with various types of coating including polyurethane and epoxies. Natural fiber covers work well with oil-based paint.
