When you are painting your home's interior or exterior, should you use a paint sprayer or a paint roller?
It's a choice that many do-it-yourselfers face, and it can be quite a dilemma. After all, paint spraying is fast: no one can doubt that. But what about all of that preparation work? Paint rolling is slower than spraying, but you're able to lay down a thicker coat. Plus, you'll have less prep work.
There is no single answer; the answer applies to your own situation and sometimes even to your own personality and your likes and dislikes.
When You Should Use a Paint Roller
You Haven't Used a Sprayer Before
As a do-it-yourselfer, it's difficult to go wrong with rolling on the paint. Painting professionals agree rolling paint produces a thick paint layer and excellent color consistency. Paint spraying may seem easy at first, but it can be tricky to learn to do well. If you've never used a paint sprayer before, now may not be the best time to learn.
You Don't Like Masking
While you do need to mask out some areas when paint-rolling, it does not compare to the huge amount of masking you will need to do when spraying.
Consider that with paint spraying, every square inch that you don't want to be painted must be masked in film or with a drop cloth. Whatever you neglect to mask when spraying will get painted, like it or not. Rolling vastly reduces the amount of masking you will need to do.
You Are Only Painting Walls
Are you painting only the walls and not the ceiling? This factor may tip things in the direction of paint-rolling for you. When you roll on paint, it is relatively easy to exclude the ceiling. There is no need to use masking film on the ceiling when rolling walls.
You Prefer Simplicity
Roller, roller cover, paint tray, and tray liner: these are your four main painting supplies when rolling. Also, with the roller method, it is easy to jump into your painting project for a while, then put it on pause so you can attend to the rest of your life. With paint spraying, it is an all-or-nothing project that consumes your entire day. Starting and stopping throughout the day is not an option with spraying.
You Need to Stay Within a Budget
Paint spraying wastes an incredible amount of paint when the atomized paint drifts away. With rolling, nearly every drop ends up on the surface.
According to Products Finishing, it's estimated that as much as 20% to 50% of sprayed paint ends up elsewhere than the intended surface depending on the type of spraying tool employed. Also factor in the cost of tools. All roller items are inexpensive compared to the purchase and maintenance of a paint sprayer.
You Need to Cover a Dirty Surface
While it is always best to thoroughly clean the surface before painting, sometimes this doesn't happen. If so, paint rolling is here to help.
Paint rolling allows you more leeway when the surface isn't perfectly clean. Rolled paint goes on thick on the initial coat and bonds better to the surface. The tiny paint droplets produced by spraying do not connect with each other as well as rolled-on paint.
Professional painters have a clever technique that combines the best of spraying and rolling: back-rolling. Paint is sprayed on the wall then is quickly rolled down, fusing the droplets together.
When You Should Use a Paint Sprayer
While rolling has its points, paint sprayers do exist for a good reason: they are fast. You may wish to use a paint sprayer if some of these conditions are met.
When the Interior Is Empty
When the room is in the early phases of building or remodeling, it is a blank canvas. This canvas lends itself well to paint spraying.
You can spray with abandon, masking off only a few key areas such as plumbing stub-outs, electrical boxes, and windows. When a room is at this point of remodeling, it will always be faster to spray than roll the paint.
When Painting an Exterior With a Clear Perimeter
Exteriors with mature landscaping, extensive decking, sunrooms, playsets, garages, and anything else close to the house that will not be painted significantly drags down your preparation time.
A clear perimeter means that you only need to mask items on the house, not around the house.
When You Have Lots of Details and Texture
Paint sprayers make short work of complicated textures, such as those found on crown molding, popcorn or cottage cheese ceilings, built-up baseboards, deep exterior textures, cornices, dentils, or masonry. Paint sprayers have the ability to work into the narrowest crevices, laying down a thin coat. By contrast, brushing or rolling detailed surfaces can result in pooled-up paint and drips.
