Brushes & Rollers

Are there different paint brushes for oil-based paint versus latex paint?

For latex products, a 100 percent nylon paint brush, or a combination of nylon and polyester, is the best choice. For oil-based products, a Chinex bristle or ox-hair bristle paint brush will give you great results.

What is the difference between a Dale brush and a Glide Paint brush?

Both are trim paint brushes and used for "cutting in," which is the process of applying paint around trim, doors and other areas. A Dale paint brush is thinner than a Glide paint brush and is a little easier to use, although the Glide paint brush holds more paint. The Dale brush has square corners and the Glide paint brush has round corners, which is largely a matter of personal preference. Homeowners/do-it-yourselfers with limited paint experience should probably start with the Dale paint brush since it is easier to use. Professionals and experienced DIYers tend to prefer the Glide paint brushes.

Why can't I use a White China bristle brush (or any natural fiber brush) with water-based paints?

White China bristles are made from natural fibers like our hair. When the bristles get wet, the brush becomes soft and has no backbone. Synthetic filaments retain their stiffness and body with all types of finishes.

What is the difference between a nylon/poly paint brush and a 100 percent nylon brush? What is the advantage, if any, to adding polyester?

Professional painters often prefer a 100 percent nylon brush for painting interiors with latex enamels. However, nylon reacts to heat and humidity by getting softer and harder to use. Nylon processes better than any synthetic filament (tips and flags) and is twice as abrasion resistant as polyester and seven times as natural bristle.

Polyester adds stiffness retention to the paint brush and helps limit the reaction to heat and humidity, so they are ideal for exteriors, as well as interiors. These brushes work with all types of paints and stains and are considered all-purpose paint brushes.

It is worth mentioning that Purdy synthetic filament paint brushes perform exceedingly well in oil-based paints. This is due to the various processing and finishing steps in our manufacturing operation that soften the synthetic material and eliminate "drag" when used with oil-based paints.

Both the 100 percent nylon and nylon/poly blends allow paint to flow smoothly; thus, the choice comes down to the environment. If your climate has high heat and humidity at the time you will be painting, use the poly/nylon blend. If not, select the brush you prefer.

What kind of roller do you suggest using for painting a bathroom with a satin latex paint on a drywall surface?

We are assuming the drywall has been primed and is ready for paint. Use a 9" White Dove roller cover in either a 1/4" or 3/8" pile height for the best results.

What differences will I notice upon picking up some of your new roller systems (e.g., ease of use, speed of production, how much paint the roller holds and lays off, etc.)?

Professional painters will immediately be able to see and feel the difference in these rollers. The first thing they'll notice is the comfort. Purdy's new products have been designed using lightweight, ergonomic materials that reduce fatigue and fit comfortably in the hand. However, the ergonomic construction of our new products is only one of the benefits. All of our paint roller systems, including the standard 9" cageless frame and Jumbo Mini Roller, have been engineered to create a smooth rolling action when carrying a full load of paint. And, the roller covers are designed to carry large volumes of paint without dripping, clumping or shedding when released on the wall surface.

Should I use a 3/8" nap roller cover when applying flat enamel paint over previously painted drywall?

It really depends on the condition and texture of the wall. Using a 3/8" nap roller cover will leave a very nice, smooth finish, but is not a production tool. If the wall has a medium to heavy texture, then you might move up to a 1/2" or even 3/4" pile height.

Do I need a slightly different painting technique when rollers have different fibers, formulas, pile heights, etc.?

Before painting, all synthetic roller covers require some form of preconditioning. If using latex paints, the cover should be lubricated with water and spun to remove excess moisture. This will prevent the paint from attaching fibers and provide an optimal level of release. If using an oil-based paint, the roller cover should be lubricated in a paint-thinning solvent. Mohair roller covers should also be preconditioned this same way. Due to their natural oils, lambskin roller covers do not require any preconditioning. Remember ... preconditioning your roller cover will greatly improve its painting performance.
