There are many advantages to using a foam roller to paint your interior doors. If painting is not your full time job, you will have a much easier time of obtaining a flawless finish with a foam roller. The roller will spread the paint more smoothly and evenly, and it won't leave brush marks or a bumpy surface.
There is an easier way! A foam roller. I much prefer to use a foam roller when painting any type of furniture or door. A foam roller ensures that there are no brush marks, no roller marks, and you get a beautiful even finish.
You guessed it – the best thing to use to paint a front door is a mini foam roller. The high density foam will give your door the perfect smooth finish!
Walls, Wood, and Metal - Small 1/4″ nap roller covers or foam rollers will produce the smoothest finish. Light to Medium Textured Surfaces - Microfiber rollers are best. Smooth Surfaces - Use a white woven short nap roller for an ultra fine finish.
Painters often use traditional rollers for uneven exterior walls and foam rollers for smooth interior walls, doors, and cabinets. Foam rollers glide along a smooth flat surface very easily and dispense the paint on the surfaces evenly. Foam rollers tend to last a shorter period of time than traditional rollers.
Roller Marks
Similar “stipple” can occur if you use low-quality paintbrushes too. You are more likely to see roller marks when you are painting with latex paint. To prevent this problem, pre-dampen the roller cover and then thoroughly shake out any excess water before starting to paint.
Rolling over an acutely torn muscle could hinder the repair of the muscle and at the very least would be incredibly uncomfortable and painful. Please note that scientific evidence supporting the use of foam rolling for therapeutic reasons is sparse and caution should be taken by anyone who uses them.
Foam Rolling a Cold Muscle
When you spend too long on one spot, you risk bruising and injury, especially when you do it before a workout on a "cold" muscle (aka a muscle that hasn't been warmed up through activity), says Lemmer.
DON'T roll directly on a joint or a bone. DO seek the advice of a professional if you have neck pain; the neck is too sensitive for foam rolling, and you could cause yourself serious injury. DON'T roll your lower back; this will cause the spine to contract in an effort to protect the spine.
If you are going to paint a plain, flat door, use a foam roller to roll on the paint and use an angled brush to paint the sides. You want to make sure you leave no roller lap marks. To remove any lap marks, roll a lightly-loaded roller over the wet coat of paint to smooth.
Get the right brush
I recommend painting doors with two different brushes; an angled 1 1/2 inch brush for the detail and edges and a 3 inch, straight brush for the rest. I find that the finish is more consistent if I use a brush for the whole door rather than switch between a brush and roller.
Painting Your Door While It's Removed From Its Frame
Pros: Gravity won't be as much of an issue with your door laid horizontally. It's easier to paint with long, smooth brush strokes. Painting paneled doors is a lot easier when painted horizontally.
Fortunately, you can remove roller marks by using a wet sponge and some sandpaper. Once your paint has dried off, rub down the surface using your sandpaper. Be sure not to get rid of too much of the paint because the only goal is to even out the coating.
Possible Cause
This can occur when: The incorrect roller cover is used. Lower quality paints and/or rollers are used. The incorrect rolling technique is applied.
It loosens muscles and fascia, relieving pain and tightness and most people will never cause any of the negative effects that can come from loosening up both muscles and fascia. The true negative effects that come from foam rolling is that it can mask other problems that can lead to greater injury.
“All active people are advised to foam roll,” he says. “That way, you can relieve tight muscles faster and loosen up trigger points [aka knots].” It provides a large surface area for you to work on large muscle groups, so it's the holy grail for your hamstrings, quads, calves, and back.
We recommend foam rollers for those who want to sleep while styling as opposed to plastic rollers, for comfort purposes. Magnetic and Velcro rollers work well if you have chemically treated, thick or fine hair, since they impart fuller body and long-lasting curls and only require about 15 minutes to lock in the style.
