Painting — FAQ
What makes a paint roller kit 'contractor-grade'?
Contractor-grade kits feature steel or reinforced frames, woven fabric covers with phenolic cores, and components that survive 50+ cleaning cycles. They prioritize durability and consistent performance over low price points.
How often should contractors replace roller covers?
With proper cleaning, quality covers last 30-50 jobs. Replace when nap mats down, shedding increases, or paint release becomes uneven. Daily painters should rotate covers weekly and replace monthly for optimal results.
What's the best nap thickness for interior walls?
3/8-inch nap handles smooth to lightly textured drywall. For orange-peel texture, step up to 1/2-inch. Knockdown or heavy texture requires 3/4-inch. Keep multiple naps on hand for different surfaces.
Should contractors wash or dispose of roller covers?
Wash quality microfiber and woven covers—disposal is expensive long-term. Budget polyester covers under $3 are disposable. Professional-grade covers over $5 repay their cost after three uses versus buying new.
Do I need an extension pole in my kit?
Yes. A 3-4 foot pole eliminates ladder work for 10-foot walls. Look for stainless steel or fiberglass poles with positive-lock mechanisms. Avoid cheap twist-lock poles that collapse under pressure.
Foam versus microfiber covers: which is better?
Microfiber holds more paint and works with all sheens. Foam delivers smoother finishes on doors and cabinets but loads less paint. Contractors should own both: microfiber for walls, foam for trim and enamel work.
