Back-rolling is a technique used to ensure the proper adhesion of paint to surfaces. It is not always necessary when using a sprayer, but it can improve the quality of the job. The easiest way to apply primer and paint to textured surfaces is to spray it on with an airless sprayer and then back-roll it by hand with a roller to ensure adhesion.
Backrolling is only necessary when using a roller to apply paint, as the pressure from the sprayer will ensure proper adhesion. However, it can cause headaches when deployed on non-porous mediums like metal. When using a roller, the pressure from the sprayer will ensure that the paint adheres properly to the surface.
Backrolling right after spraying works the coating into the surface more efficiently than spraying alone, promoting better adhesion between the coating and the substrate. Almost always, application via a roller requires two coatings to ensure adequate coverage. Backrolling your first coat helps with adhesion, while backrolling your final coat helps with touchups and helps eggshell have an even sheen. If the prepcoat is being applied by spray and is not going to be sanded, back-rolling the prepcoat should be carried out while the paint is still wet.
It is always good practice to back roll or back brush after spraying, building stipple for easier touch ups. Paint Pals recommends back-rolling only on very porous substrates, as the roller can help work the paint into small nooks and crannies.

Do professional painters spray or roll?
Professional painters utilize both sprayers and rollers, depending on the specific requirements of the job, the surface type, and the desired finish. Spray finishes provide a more even and seamless appearance, free from the visual evidence of brush strokes. However, the optimal choice of finish is contingent upon the specific surface material and the particulars of the project. Rollers are frequently employed by professionals due to their capacity to provide uniform coverage over expansive surfaces in a relatively short time.
Can you wait too long between coats of spray paint?
In order to achieve comprehensive coverage, it is recommended to allow a period of 48 hours to elapse following the initial application of paint before applying additional coats. This is due to the fact that spray paint applied after the first hour may warp and result in an unkempt finish. It is imperative that the paint be permitted to dry entirely for a period of 24 to 48 hours prior to utilizing the item in question.
Do you waste more paint with a sprayer?
The use of paint sprayers entails a significantly higher consumption of paint than other methods, with the potential for up to 33 additional cans to be used per project.
Do you need to back brush after spraying?
Back-brushing is a process that involves working paint into a rougher surface after spraying it, ensuring a better bond with the surface. This is particularly important for rougher surfaces like cedar siding and T1-11 siding, which have become cracked and weathered over time. However, new, pre-sealed surfaces, such as hardy plank siding, do not need back-brushing.
When tackling a large and extensive exterior painting project, homeowners may not have the necessary equipment or equipment like an airless sprayer. Consider hiring a professional painting contractor like Sound Painting Solutions to complete the job efficiently. They will take all necessary steps to prepare and seal the surface, including covering surrounding areas and plants, removing old and peeling paint, caulking, and back brushing.
The contractor will provide detailed descriptions of each step required for preparing the surface in their initial proposal and offer a warranty to ensure customer confidence even after the job is completed. By hiring a professional, homeowners can ensure a smooth and efficient exterior paint job.
Do you have to backroll after spraying the exterior?
Back-rolling is a technique employed to achieve a smoother surface by reducing the height of raised fibers and enhancing the adhesion between a coating and the substrate, which is typically drywall in residential interiors. Although some practitioners eschew the back-rolling technique for various reasons, it can enhance the quality of the work by facilitating more efficient coating application and smoothing out any raised fibers. Nevertheless, there is no optimal scenario for back-rolling.
Do you need 2 coats when spraying?
When using an airless sprayer, the number of coats needed depends on the paint type, surface, and desired finish. In general, 2-3 coats are needed, with the first being a primer coat for better adhesion. If the surface doesn’t require a primer, a single coat can be applied. Topcoats typically require two coats for good coverage and a smooth finish. Some paints may require more coats for optimal results, so follow manufacturer’s instructions and perform a test patch before starting the project.
Is back-brushing necessary?
Back-brushing is a process where paint is applied to a rough surface after it has been sprayed, using a brush or roller to work into cracks and crevices. This helps create a better bond between the paint and the surface, especially on rougher surfaces like cedar siding or weathered surfaces. New, pre-sealed surfaces typically don’t need back-brushing. Homeowners may not have the necessary equipment for extensive exterior painting projects, so hiring a professional is recommended.

Is it better to roll or spray exterior paint?
The choice between spray and rolling exterior paint tools is complex. While sprayers are often preferred due to their efficiency, better coverage, and professional finish, it is essential for a painter to use both tools to achieve the best paint job. For porous surfaces like brick or stucco, a sprayer is recommended, while a roller can be used to “back-roll” the paint in. For smoother surfaces like trim, wood, lap, vinyl, or metal siding, spraying is more suitable as it eliminates roller marks and allows for different angle angles to ensure full coverage.
Both tools should be used under different circumstances, and the choice between spray and rolling depends on the specific needs of the project. For more inspiration, check out our gallery of exterior paint projects and Instagram for more inspiration.
Does exterior paint need two coats?
It is standard practice to apply two coats of exterior paint to a surface that has been adequately prepared and primed, particularly when painting a dark color over a lighter one. In the event that a lighter color is being applied over a darker one, the necessity for additional coats may be greater than two. To facilitate a seamless transition, it is advisable to utilise a tinted primer.
How long does exterior spray paint take to dry?
Spray paint is a quick and effective method for painting furniture, metalworking, siding, and home improvement projects. It typically takes five minutes to eight hours for paint to dry and 24 hours for it to fully cure. The drying time depends on several factors, including the type of paint, material, surface texture, temperature, humidity, and airflow. There are various types of spray paint, including fast-drying, acrylic, latex, oil-based, lacquer, epoxy, and rust-preventive enamel spray paint, each with different drying times.
The type of material and texture of the target surface also affect the drying time. Common materials include wood, metal, and plastic, with texture varying between rough, smooth, porous, and nonporous.
Is one coat of spray paint enough?
To achieve the best results with spray paint, plan at least two thin coats. For bright colors like yellow or orange, plan 1-2 additional coats. Most neutral or deep colors only require 2-3 coats for an opaque coating. To determine the overall square footage of the surface area needed, break the surface into rectangles and multiply the area by length and width. This gives you the overall square feet.
Divide this by 20 square feet or the coverage of your spray paint, which gives you the number of spray cans. If the area is measured in inches, multiply the inches to get the total number of square inches and divide by 144 to convert this into the total number of square feet.

Hey Chris, how do you start the process with your roller cover when you first start out? Do you need to load the roller at the very beginning or at any point during the process? I’ve seen several articles of people backrolling but they all start mid job and it looks like you don’t need to load between backrolling but I’ve never seen anyone start. Thanks for your articles, they’re quite helpful.
Some painters I worked with years ago seemed to think you never need to backroll when you spray. WRONG! If the substrate is smooth and sealed, backrolling is never required. If its rough like stucco or had failed but now sanded and prepped paint I still backroll. Paint fails quickly, even expensive stuff within months if water has the opportunity to get behind it. Once the rough surface is properly sealed whether with priming or that backrolled first coat, the final coat can be applied with spray only.
So instead of an explanation as to what, exactly, back rolling and back brushing ARE, or even a shot of someone doing these techniques so we can see them, we are treated to three minutes of a carefully posed, muscle-flexing guy in his favorite too-tight shirt who probably sees himself as a youtube celebrity. Okay.
Great!! I would like to actually see the process. How do you determine how much paint to put on your roller. Here in the midwest we typically roll on interior and spray and backroll the exterior. I have watched the guys I hire when the do the outside but it is still a mystery as to the technique. Thanks for all your great articles!!
Did you actually define what “backrolling” is? Is it just going back over walls that were sprayed? Besides owner preference, what is the purpose/effect of backrolling? I have a customer who doesn’t want to do any kind of texturing by spraying it on but said if I spray it and roll right afterwards it will create a semi textured look. Is that essentially what “backrolling” is?
Hi Angel ( your dog)! I am sure you answer this question in one of your other articles, but when spraying new construction topcoat what tip do you use to avoid the lap marks when you don’t backroll? Secondly, on interior repaints what percent of the time do you roll vs. spray? From the articles I assume you roll interior repaints like 90% of the time?
Thank you for all of your helpful articles. I am thinking about using an airless sprayer to prime new drywall and was not clear if you would typically back roll after you prime or after your finish painting. I will probably use rollers for the finish painting since there are so many colors. thanks for your help input!
Hi Thank you very much for your articles, all of them are very helpful! I need help with airless sprayer.I bought Graco 390pc and I’m going to use only for interior spraying of walls and ceilings and interior woodwork . When I have to backroll,I mean always ? What about new plastered walls,over wallpapers,over old painted walls. Thank you!
Back rolling is a better paint job. The reason you backroll is there is dirt and shit that is always going to be on exterior walls. When you back roll, you mix that dirt and shit in with the new paint, so it adheres to the walls better. Notice he said when the builder doesn’t require it, we don’t do it. Yes it’s cheaper not have your painter back roll. But spraying paint that lays on the top of dust or dirt will always be inferior than using a roller to back roll all that crap in with the paint.
