For interior projects, foam or microfiber rollers with a 3/8-inch nap are usually used for smooth surfaces like walls and ceilings. For exterior projects, longer naps, such as 1/2 inch to 3/4 inch are best suited for rough surfaces like stucco or brick.
Walls, ceilings and paneling require a slightly larger nap size of 3/8-inch; for lightly textured walls, decks and concrete, use a ½-inch nap; and for textured ceilings, stucco and masonry, use ¾-inch.
Quality 12mm nap rollers will apply an even paint film to your walls and ceilings and give you a great finish, without splattering paint all over you and the floor. Professional painters actually use 20mm nap rollers on ceilings, and 12mm nap rollers on walls.
1/2 Inch Nap vs 3/8 Inch
A 3/8 nap is sufficient if the surface has no texture or a simple roll-on texture. However, if the wall is textured with concrete or plaster, using a 1/2-inch nap or greater as necessary will ensure you apply for the proper paint coverage.
A nap size of 3/16 to 1/4 inch is effective for painting with a roller on smooth surfaces, such as smooth wallboard, drywall, metal, and smooth plaster. A nap size of 3/8 to 1/2 inch is preferred for most ceilings and walls, acoustic tile, paneling, smooth concrete, textured drywall, and wood.
The Medium Pile Microfibre Roller
Probably one of the most popular and reliable rollers on the market, these are designed to apply water-based emulsions, such as matt and silk paints, to internal walls and ceilings.
The trickiest part about transitioning from 3 naps to 2 is that wake windows need to be longer than before. Stretch wake windows by adding engaging activities. Continue with a nap time routine. A predictable nap time routine sets your little one up for a restorative nap.
Keep naps short.
A 20- to 30-minute nap is ideal. Try not to snooze more than 30 minutes on a regular basis. The longer you nap, the more likely you are to feel groggy afterward.
⅜” - ½” (9.5-12.7mm)—For smooth and semi-smooth surfaces like drywall, painted or unpainted walls and ceilings. ¾” - 1” (19.05-25.4mm)—For semi-rough surfaces like wood, stucco or a textured ceiling. 1 ¼” - 1 ½” (31.75-38.1mm)—For rough surfaces like concrete block, brick, or masonry.
Yes, pro painters often reuse their rollers after thoroughly cleaning them post-use to maintain optimal performance while saving resources.
For those looking for paint rollers for a smooth finish, high-density foam rollers should be your first stop. While high-density foam rollers are great, they are not the only option. Lint-free short nap rollers are another excellent choice for achieving a smooth finish.
A 3/8″ roller nap is ideal for most interior walls, metal, and smooth surfaces. A 1/2″ roller nap is excellent for drywall interior walls and ceilings. A 3/4″ roller nap is best for exterior walls and popcorn ceilings. A 1 1/4″ roller nap is reserved for the most textured surfaces.
Smooth Surfaces - Use a white woven short nap roller for an ultra fine finish. If you use a thick 3/4″ roller cover on a smooth wall, it will produce an orange peel textured surface.
More often than not, roller marks occur when you fail to load your roller with enough paint, or have exhausted the paint in your roller and are trying to cover more area than you should.
Glossy paint: 1-1 ½ hours and 2 hours before applying the second coat. Semi-gloss: It takes roughly 1 hour to dry and 2 hours before applying the second coat. Matte Paint: 30 minutes to an hour for drying and 1-2 hours before applying the second coat.
Elevate your legs so they're above your heart
Before you fall asleep, prop your legs up on a chair, the edge of a couch, or even against a wall — the key is to make sure they're above your heart level. Why? This helps the blood flow back to your heart and brain more easily and helps you relax faster.
A power nap that lasts 20 to 30 minutes is usually ideal. It's long enough to give you all the benefits of sleep without leaving you feeling groggy when you wake up.
Consider the 2-3-4 Nap Schedule
It works by gradually increasing the amount of awake time between naps over the day. According to this approach, the first nap is about two hours after waking, the second nap is three hours after the end of the first nap, and bedtime is four hours after the end of the second nap.
The 3 to 2 Nap Transition Takes Time
Remember this is one of the most difficult nap transitions, and it will likely take your baby 4-6 weeks to become acclimated to these longer awake windows and new schedule.
The Ferber method, or Ferberization, is a technique invented by Richard Ferber to solve infant sleep problems. It involves "sleep-training" children to self-soothe by allowing the child to cry for a predetermined amount of time at intervals before receiving external comfort.
Many painters “break in” a roller cover by priming it with water or thinner. In our lab we never prewet a cover before painting. If you choose to, you must spin it out with five or six strong pumps so it is only lightly damp. Then take even more moisture out by blotting the cover with a paper towel.
Professional painters typically use both brushes and rollers when painting. Brushes are used to apply paint in tight spaces or areas with intricate details, while rollers are used for larger surfaces like walls and ceilings.
