Painting — FAQ
What roller size is best for bathrooms?
Use 9-inch rollers for walls and ceilings to maximize coverage. Switch to 4-inch mini rollers for tight spaces behind toilets, around vanities, and for trim work. A combination of both sizes completes most bathroom projects efficiently.
Foam or microfiber for bathroom walls?
Microfiber is superior for bathroom walls due to better paint pickup, durability, and moisture resistance. Foam works well for cabinets and ultra-smooth finishes but can break down faster. For humid environments, microfiber's longevity makes it the smarter investment.
How do I prevent mold on paint rollers?
Clean rollers immediately after use, removing all paint residue. Dry thoroughly in a ventilated area before storage. Consider adding a drop of bleach to final rinse water. Store in a dry location, never in sealed plastic bags while damp. Replace rollers showing discoloration or odor.
Can I use the same roller for primer and paint?
Only if you clean the roller thoroughly between applications. Better: use separate rollers or tray liners to prevent contamination. Primer residue in the nap can affect paint sheen. For bathroom projects where adhesion is critical, dedicated rollers for each coating ensure optimal results.
How do I clean rollers after painting bathrooms?
Rinse immediately with warm water until water runs clear. For oil-based paints, use mineral spirits. Work the nap with your fingers to release paint from the core. Spin dry or use a roller spinner. Stand on end to dry completely before storing. Never leave soaking in water.
What nap length for textured bathroom walls?
Use 1/2-inch nap for light to medium texture. For heavy orange-peel or knockdown texture, step up to 3/4-inch. Smooth drywall needs only 3/8-inch nap. Longer naps hold more paint but can create stippling; match nap length to your wall texture for even coverage without excessive buildup.
