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.
Foam roller covers work great with latex paints, as they are made for a thinner paint. Oil paints are generally too thick to achieve good results with a foam roller. Foam rollers are also ideal for smooth surfaces. The uniform thickness of the foam means that they aren't the best choice for rough surfaces.
Foam rollers are often recommended when a very smooth, glossy surface is required. They can be used with both oil- and latex-paints, semigloss or high-gloss, and are a good choice for a wall of built-in cabinet doors.
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.
If you're painting a ceiling and walls, the common 9-inch medium pile roller is your best choice. Try it with an extension or use a pole roller to reach those out-of-reach areas such as stairwells. If you want to give your doors, kitchen cabinets or furniture a smooth finish you'll need a 4-inch foam roller.
Hamilton are a brand associated with the trade and these rollers are possibly the most widely used by professional decorators.
Patchiness usually happens if you don't use enough paint, or apply it unevenly. Using a touch more paint, and painting in small sections one at a time, usually does the trick. Also, rolling in a grid fashion will get you an even finish too. But, sometimes, changes in the gloss level leave things patchy.
POSSIBLE CAUSE. Shaking a partially filled can of paint or using too high of a speed when using a drill mixer. Excessive brushing or rolling – applying a paint too rapidly – will drive excess air into the film. Use of a roller cover with wrong nap length.
Before using a roller cover, it should be pre-wetted with water if a latex paint is being used, or mineral spirits for an oil base paint. The cover should then be spun or dabbed with a rag or paper towel to remove the excess liquid.
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.
To avoid air bubbles in the paint film, don't use spongy foam rollers with normal emulsion paints. Before you use it, don't forget to wash the roller in warm, soapy water to eliminate any fluff.
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.
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.
Using a filter or strainer like tights, cone filter, or stockings, you can do this. Then pour the paint through the strainer and allow it to collect in a clean container. After that, you'll get smooth paint without dirt that you'll roll on the wall and not get orange peel.
Large paint roller: 12 – to 18 – inch rollers, a bigger paint roller size. A long nap roller is best used for painting by professional.
The porous surface of the roller holds much more paint than a brush and distributes an even layer of paint much faster. Different finishes can be achieved with different rollers: Rollers with a smooth surface will produce a smooth finish.
Generally, latex has a much thicker consistency that oil-based ones. Hence, you will need to thin it first before use to ensure the even and smooth application on any surface.
A knit roller cover is recommended for applying flat, eggshell, or satin paints and stains. A wide variety of paint and hardware stores carry microfiber and foam roller covers as well. If you apply any type of paint, varnish, or enamel with either of these roller covers, you will get spray-like results.
Generally, you will want a minimum of two coats of paint – this is a good rule of thumb for any wall or ceiling you're painting. You'll rarely get a seamless finish from just one coat of paint, and even if you do, coverage isn't the only goal when it comes to painting a room.
One coat of paint is more difficult to clean because paint soaks into porous surfaces. The second coat provides a type of seal and barrier, which makes it easier to wipe and clean. Durability is also better with two coats of paint.
The general rule is that you should use two coats of paint. However, this rule changes based on the color, quality of the paint you use, whether or not you used primer, and the type of surface you're painting.
