I get asked a lot why we don’t spray our primer on window sashes. Just the other day one of my employees asked the question, hoping they had thought of something that might make our jobs easier and the work move faster.
While spraying on paint and primer is much faster, the gains in speed come at a cost. In this post I want to look at some of the pros and cons of both so you can make an informed decision when the time to repaint comes.
Spraying Paint
There really is no faster way to apply paint than using an airless sprayer. You can cover an entire wall in minutes instead of hours, but like everything, speed doesn’t always equate to quality. Here are some of the key benefits of using an airless sprayer.
Benefits
- Incredibly fast application
- One coat coverage
- Smooth finish free of brush/roller marks
- Can get into hard to reach areas
So, why wouldn’t everyone just spray everything all the time? Well, there is a downside to spraying too.
Negatives
- Long prep and clean up time
- Uneven coverage (sometimes too thick)
- Uses 2-3 times as much paint as brushing
- Poor adhesion
- Can’t paint on windy days
Applying paint with an airless sprayer can be very challenging if you don’t have a lot of practice using the sprayer. Like any tool, airless sprayers take a lot of practice before you can apply a smooth even coat of paint. Beginners will get over-spray, drips and runs, they’ll often have an uneven coat with some spots of heavy paint build up and some spots that are just too thin.
Paint spraying also uses 2-3 times as much paint as brushing or rolling. Not all of that extra paint goes onto the house either. Most of it ends up wasted in the hose line or as over-spray.
Even with these issues, there are some tight spots like around utilities that can’t be done cleanly without spraying and you really can’t beat the speed.
Brushing Paint
It’s the old-fashioned way of doing things so I probably love it, right? To be honest, I have a love/hate relationship with brushing on paint. It’s slow and tedious and often results in brush marks if I’m not careful, but nothing gives me control like applying paint with a good brush. Just like with spraying, let’s look at some of the benefits and negatives of brushing.
Benefits
- Excellent control
- Very good adhesion
- Even, uniform coverage
- Gets paint into nooks and crannies better than spraying
So far, it looks like brushing solves the main problems we faced with spraying, so we should always brush, right? Not so fast.
Negatives
- Slow, laborious application
- Can require 2 or more coats
- Can leaves brush marks
- Obstructions make for difficult application
Nothing come close to the control you get with a quality brush. You can cut in tight corners and paint nice straight lines that are impossible to attain with a sprayer. For detail work, the only acceptable way is to use a brush. Yes, it is slow, but you will get an even, uniform coat of paint and much better adhesion than with spraying alone.
How to Get the Best of Both Worlds
Now that I’ve got you all twisted up thinking neither one is better than the other, I want to offer you a solution that will change the way you paint.
Often with old houses the best answer lies in using yesterday’s techniques combined with today’s technology. Painting is one of those times.
In my studies and day to day practices, I have found the best way to apply paint is by applying with an airless sprayer and “back-brushing.”
Back-brushing is the practice of brushing over paint that has been applied with either a roller or sprayer. To do it properly, you’ll need a helper.
“But this seems like more work. Why would you do this?”
Using this technique, you are able to get the paint onto the surface quickly and brush it in before it dries. Back-brushing forces the paint into all the nooks and crannies, evens out the coat and works the paint into the surface giving you better adhesion for a lasting paint job.
You see, what slows you down when you apply paint with a brush is that you can only load so much paint onto the brush at a time. By spraying and back-brushing, you can cover large areas almost as quickly as by spraying alone. You get the benefits of both systems and eliminate most of the negatives.
Can you say win-win?
Have you tried this before? What do you think works better? I’d love to hear your thoughts in the comments below.

I love old houses, working with my hands, and teaching others the excitment of doing it yourself! Everything is teachable if you only give it the chance.
Thanks Scott for your post. I prefer Sprayer than Brush. Because It can give smooth finish with very little waste.
I love that you mentioned how using a spray paint can reduce the amount of time that you need to dedicate to a paint job. We’re thinking of having our kid’s rooms repainted because they already outgrew the existing ones. We want to give it a fresh, vibrant vibe. To make things more interesting, we want to make it as a bonding session where we can all paint as a family. Learning a few pointers from your article, I now understand that spray painting a certain level of expertise. Otherwise, the paint job may end up uneven. I’d be sure to get professional spray painters instead to help us with the project. Thanks for this informative read!
We have a rough plaster exterior house. One painting compnay has offered to paint using spray and rollers. The other uses brush method. Originally painted with brush it has seen out twenty years and even now doesnt look like it needs repainting but we think it best to be preventative . Would you engage the spray/roller painters or the brush painter?
Hi Dot! Personally, typically we are advocates of “if it was done with ____ method initially, stick with ____ method again.” in reference to historical homes. Hope that is helpful to you!
Best wishes to you on your journey and I hope you have a great week!

We are using Romabio mineral paint for the interior of our new build 2800sf home. The painter for the project would like to spray paint and not use roller. Our interior walls are very simple with no crown molding, window / door trims are thin and flat, and a handful of large windows. Should our painter use a sprayer or a roller?
In new construction on the interior I think spraying will be just fine.
I got an uneven look (sort of wet/dry in certain places) although this was even when all was dry…by spraying some doors. (can spray paint).I had primed first. On the next door, I decided to apply penetrol conditioner to a brush and brush using only the penetrol right after I sprayed,. (In some cases it was more than 10 minutes AFTER I sprayed). Beautiful results! Even, smooth, rich looking. My question is….will the paint last having sprayed it and then applying the conditioner directly with a brush right after spraying. Love the look but want it to be a lasting paint job. Thank you for your input.
I am considering having my house painted by pros and have a bid from one company using traditional rollers and brushes and the other company proposes spraying. The siding is a textured hardboard, which is reasonably sound. Cost aside, in which approach is the appearance of the paint likely to endure. A neighbor’s house, with similar siding, was sprayed 3-4 years ago, but the appearance has declined recently. Given comparable quality paints, which approach endures better roller and brush or spray painting?
Spraying and backbrushing or rolling is the best option. If you just spray then the adhesion is not as good.
This really needs to be updated. I’m spraying Keim paint with HVLP and getting nearly 90% total transfer rate. Rolling is so incredibly wasteful. The big nozzle airless stuff is old and somewhat comparable to being disappointed at the performance of a Commodore 64 when your neighbor just bought a modern Lenovo ThinkCenter.
What is the price comparison? I have 2000 sq ft house, and my husband thinks traditionalnpainting and I am thinking spraying. Which is cheaper?
Spraying is always cheaper. Try having them spray and then back brush. You get the benefits of both lower cost and higher quality.
If spraying is wasteful, how can it be cheaper?
Love the fact we can NOW spray! It’s about time! I have a lot of inside work to do. But as a woman I am not as in touch with terms like HLVP, and I think that is a major necessity according to your text. I would be so thankful if you could explain that acronym ? And any other thing that might lead me to a quality sprayer? Thank you.
HVLP High Velocity Low Pressure sprayer
Very astute. I agree ! Cheaper but more expensive?
Your materials cost is greater with spraying but your labor cost is MUCH lower. That’s how.

Any Recommendation on painting Pergola. If airless spray or roller+Brush?
In my studies and day to day practices I have found the best way to apply paint is by applying with an airless sprayer and “back-brushing”. This all have done by reading your article
I’m currently refinishing my oak kitchen cabinets. I’ve tried brushing on the paint and rolling it, but neither technique gives me the glass smooth finish I want. There is always either brush strokes or a hint of texture from the roller. Should I try spraying the paint? If you spray on the paint, do you also spray on the primer as well?
Robyn, brushing rolling or spraying can all work as long as the paint can level out. Oil based paint dries slower and can level better or try adding some additives like penetrol or floetrol to the paint to slow drying times and help you get a better finish.
I need to paint slatwall. It’s a paint grade slatwall, so need to prime first than paint. I don’t have metal inserts , so have to paint inside also. What is better to use , spray or roller?
Brushing or Spraying? That is the question. 🙂
I prefer spray painting cause it give me the smooth finish I want
Sir Scott,
I have question regarding the mechanization in the Apartments. If I have out of brush or air less spray, which are the best parameter to look after. Is it really true that paint consumption will increase to 2-3 times (as you mentioned). Waiting for your reply.
Yes, spraying will greatly increase the amount of paint used. The amount will vary but it always uses more paint to spray.
i am 60 yrs old. I have a 2 story 2 thousand sq/ft house that I’ll be painting the same color as the last pain’t job. That was 10 years ago with a brush, a 2 man crew and 6 weeks and $4,000.00 later it was painted white. No colored trim, just white. Caulking and weather slowed them down. This time I will be by myself with an airless sprayer. I have a lot of experience with metal spray painting but little on composite siding. If I spray first coat in 80 deg sun and by they time I’m done with the first coat, it’s already dry to the touch where I started. If I carefully apply a second coat immediately, do you think it would hold better and if not how long do you think it will hold up
I would paint in the rain and then be done with it.
Hello,
I’m considering painting my home with a brush because the surface area is really small (house is mostly large windows and brick) 1957 Mid Century Modern ranch house, really the only areas to be painted are surfaces between windows, soffits, roofline,and some beams. The surface to be painted is an aluminum wrapping the structure that is very smooth… will using a brush leave obvious brush marks? (is that a given?) Just seems like a lot of prep work for a little bit of spray application.
Thanks!
Carl
Carl, I agree. I would probably brush in your case. Check out this post to help you avoid those annoying brush marks. https://thecraftsmanblog.com/6-secrets-to-silky-smooth-paint/
This might be tough to answer …. How do you paint your house during this crazy wet weather. Can says: Don’t apply if you expect rain within X amount of hours. I’m wondering if I should try to find some oil base paint. Thanks
Ray, it’s tough to paint in the wet months. You really Just have to wait for dry days and work when you can. Oil based paint won’t fair any better if it gets wet before it dries.
I like the thought of rolling on paint, I am well aware of the waist draw backs of spraying, but if your working with an un-even metal siding surface like I have to, rolling is tossed out the window.. I appreciate all the comments I’ve read here, but sometimes a brush is the “one and only way”.. Had fun reading what all was wrote here!!
I like brushing more then spraying. it is a good way to paint.
I have painted several houses over the years using an airless sprayer and back brushing. I agree with what you said about it. However I no longer spray because of the drawbacks you mention, especially all the masking and waste. I find that rolling and back brushing has most of the advantages of spraying with none of the drawbacks. I set up a roller kit in a bucket so I can use a bucket hook and hang it off my ladder. I screw clips to the bucket so that I have a wide and a narrow brush with me. At the end of the day I clean out the brushes and put the bucket in a plastic bag. When I am done with the roller I use a painters tool and get all the paint off the roller and then wash it out and put it in a ziplock bag to reuse. I have been painting professionally for 30+ years.
Completely agree with you tom!
Also to add on, Touch-ups post spray application is a nightmare.
