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.
Start at one end, running the roller up and down the full height of the wall, moving over slightly with each stroke. Move backward where necessary to even out thick spots or runs. Don't let the roller become nearly dry; reload it often so that it's always at least half loaded.
Either way, the Wooster Brush Company says that the best paint roller for a smooth finish is a tightly knit, shed-resistant cover. A nap of 3/16 or 1/4 inch is ideal for smooth surfaces, such as metal, smooth plaster, smooth wallboard or drywall.
The more experienced you are in painting, the easier it will be to use a brush to paint your interior door. Foam rollers really simplify the process. They make it easier to paint the door without drip marks, and they leave a smooth finish.
Start with a medium grit sand paper and finish with a fine grit paper. Use a high quality primer with a hard finish to seal the cabinet and prepare it to accept paint. After the primer dries, sand it perfectly smooth again. This will remove any imperfections.
Skim coating, the process of covering rough walls with a thin layer of joint compound, will smooth out the wall surface. You can then add another texture, or wallpaper or paint over it.
A long sleeved mohair roller would be used to cover a textured wall or an artexed ceiling whereas a smooth foam roller would be used to paint emulsion on a nice smooth, plastered wall. The length of the hair on a roller is called the nap or pile of the roller.
To apply flat, eggshell, or satin paints and stains, a knit roller cover is recommended. Knit roller covers can pick up and release higher amounts of paint than woven fabrics because the fibers have a looped backing with a single pass-through process resulting in a more “open” fabric.
Deluxe Mohair Rollers are reusable and are made from a premium blend of red mohair. They come in a variety of sizes, with a 3/16" Nap length (short Nap), and a phenolic core. They are best used with enamels, varnishes, and urethanes on smooth surfaces.
Large paint roller: 12 – to 18 – inch rollers, a bigger paint roller size. A long nap roller is best used for painting by professional.
Using the best type of roller
Basically, foam, mohair and sheepskin rollers come in short, medium and long-pile. A short-pile mohair roller is suitable for applying silk emulsion, while a medium-pile sheepskin roller is best for matt emulsion. Short pile is the choice for very fine or flat surfaces.
Yes, foam paint rollers are suitable for certain types of painting jobs and also are a budget-friendly way to get the job done since they cost less than nap rollers. Foam rollers work well on smooth surfaces, with thinner paints, with large surfaces, when matching the trim, and for short term use.
For matt emulsion, opt for a medium-pile sheepskin roller. Don't use spongy foam rollers with emulsion paints because they create air bubbles in the paint film. A short pile roller is best for extremely fine or flat surfaces.
Here's a little guide to help you: Matt emulsion is smooth, velvety and helps to hide imperfections on less-than-perfect walls. Flat matt emulsion is even more velvety and because matt surfaces don't reflect light, they make all colours look as similar as they can be in very different light conditions.
Although a roller is easiest for applying paint to the broad surfaces of walls and ceilings, a roller will not apply paint all of the way into corners or to the edges of trim. You'll need to “cut-in” the corners and areas around trim with a paintbrush. Cut in the corners before you roll paint on the main surfaces.
Roller Cover Material
Nylon/polyester: Synthetic roller covers are ideal for applying latex paints. They resist matting and hold their shape for a smooth finish.
Though synthetics don't pick up and hold as much paint as wool does, they are generally very durable. Roller covers that blend wool and polyester can be used with either type of paint and any paint finish, so they are a great choice if you often switch between oil-based and water-based products.
Microfiber rollers are like traditional woven paint rollers but feature a wrap of microfiber cloth. Microfiber cloths are like normal cloth, but the fibers on microfiber cloths are extremely small. On a microfiber roll, the microfibers are adhered to the roller with heat, which makes microfiber rollers very durable.
A short pile roller is generally used for smooth or flat walls, or for drywalls. Less paint is taken up by the roller, allowing for easy application onto flat walls.
They may even be used with varnish. These rollers are ideal for use with oil-based radiator paints and are often used with gloss paints. Microfiber covers are made from microfiber cloth which has extremely small fibers.
A foam roller is a lightweight foam cylinder that you use to self-administer deep tissue massage. Foam rolling releases muscle knots, relieves inflammation, and improves overall comfort. It can also increase your range of motion, flexibility, and mobility while boosting circulation and lymphatic flow.
Roller marks, which painters sometimes call "holidays," are a routine hazard when painting with a roller, and there are many ways to avoid them. When you notice holidays after the paint has dried, you can usually make them disappear by applying another coat after sanding lightly—if necessary—to remove drips and humps.
This happens when the roller is full of paint and is pressed too firmly against the wall. To fix these paint streaks on walls you'll need to sand down the raised edges. You may have to touch up the wall here and there but that's only if you sand too closely. You'll want to use 120 – 150 grit sandpaper and sand lightly.
