Wooster Brush Company R298-9 9" Paint Roller Cover, 1-1/4" Nap, Knit Lambswool/Polyester

What this roller cover is for

This Wooster cover fits a standard nine-inch cage frame with a one-and-a-half-inch core. The knit lambswool and polyester blend is made for flat paints, satin paints, stains and waterproofing on extra-rough surfaces such as brick, concrete, drywall, masonry and wood. Builders who need a smoother finish on fine plaster or a cover for gloss enamels should choose a different nap.

The spec that decides fit

The one-and-a-quarter-inch nap depth is the single figure that matches the cover to the job; it holds enough coating for heavily textured substrates without overloading smoother walls. A shorter nap will leave bare spots on rough masonry while a longer nap will create unwanted texture on flat drywall. Choose this depth only when the surface profile demands it.

Thermals noise and power

This is a passive hand tool so it produces no heat, no noise and draws no power during use. The polypropylene core resists solvent softening and the knit construction sheds minimally, keeping the work area clean. Performance depends entirely on the painter's technique and the coating viscosity.
