In the above test panel, Benjamin Moore Regal Select was used in both tests. One coat was applied. On the bottom panel a competitor’s good cover costing $3.69 was used and in the top panel, an Allpro Masterknit HD costing $3.59 was used. The lesser quality cover had spotty coverage and left fabric behind in the paint and actually cost more!
Choosing the right roller cover
In most cases, you will be working with either flat, matte or eggshell paint. The surface you are painting will play a part in determining your choice of nap. The nap is the length of the fabric that sticks up from the surface similar to the pile in carpet. A good quality roller cover will hold more paint and provide faster coverage. The combination of a good quality paint and a good quality cover will give you your best job. A poor quality or inexpensive cover will allow air bubbles, missed spots and leave behind lint.
A quick note about the frame that you are using. A good quality frame has five wires which helps the cover to maintain a nice round shape. An inexpensive frame may hold up for a project but will lose its roundness over time causing poor paint flow.
A good quality cover will have a core that is cardboard impregnated with a resin for strength and durability. A good quality cover will also have more fibers per square inch just like a good quality carpet. The more fibers per square inch the better the cover and the coverage.
Covers are either woven or knitted. A woven cover will ensure the most lint-free project. A good quality cover will last you through an entire project and you will usually need one cover per color per person painting. Thus, a good cover will actually save you money.
