Painting is one of the easiest things a DIYer can do. Without much practice most people can do at least a halfway decent job of painting a room or some trim. But with a few tips you can turn that passable job into a job you can be proud of.
I’ve written extensively about painting on this blog, but felt that putting some of the best tips I can think of in a single post would create a great resource for readers like you. I’ve also included some of the most common questions from readers about painting to help everyone paint better.
Follow these simple tips and your next paint job will look like it was done by a pro!
1. Pick the Right Paint
There are exactly 1,264,994,827 different types of paint in the world today. How do I know? I don’t. I just made that number up, but there are a ton of different paints available today.
With so many choices you may feel overwhelmed and just choose a good all-around paint. Don’t! Find the paint that best suits your needs. Here is a short list of some common painting projects and the type of paint your should use.
- Wood Siding Exterior – Exterior Acrylic Paint
- Drywall/Plaster Interior – Interior Acrylic Paint (Preferably low VOC)
- Windows/Doors – Oil or Water-based Enamel
- Woodwork – Oil or Water-based Enamel
- Furniture – Chalk Paint
- Floors – Porch or Floor Enamel (designed for extra traffic)
If you want your paint to last then choose the right paint for the right job. Get as specific of a product that meets the needs of your project as you can.
2. Get a Quality Brush & Roller
Don’t skimp here. Using a high quality brush and roller makes your job look so much better. Even the best painters can’t cut in a clean paint line with a cheap brush. And a cheap roller doesn’t hold much paint so you have to continually recharge it. Not to mention, cheap brushes and rollers notoriously shed fuzz and bristles into your paint job that makes for an uneven and unattractive paint job.
I recommend Purdy brushes. They come in whatever size you need and they last a long time if cared for.
3. How Long Does Paint Take to Dry?
This is so variable according to what type of paint and what the weather is like, but I can take a stab at it. Almost every manufacturer lists the drying times for their paint on the can (if it’s not on the can call the manufacturer or ask at the paint store for the SDS sheet).
The drying times are usually figured at 77°F and 50% humidity. Warmer weather means faster drying as does lower humidity. The drying time will also depend on whether you are using oil-based paint or water-based paint.
Water-Based Paint Drying Times
- To Touch: 1-2 Hours
- To Recoat: 3-4 Hours
Oil-Based Paint Drying Times
- To Touch: 7-9 Hours
- To Recoat: About 24 Hours
Drying to touch is important in order to keep the surface from being marred of smeared by touch, but the time to recoat is often overlooked. If you rush this recoating time then you are likely to have paint that will blister and peel off. Do not rush to recoat! Wait the appropriate time and you will be awarded with a much longer lasting paint job.
4. Which Sheen Paint Should I Use?
Sheen choice is a matter of some preference but there are some major faux pas you can avoid in this topic as well. Generally, the flatter a paint is the better it hides imperfections, and the glossier a paint is the better is can be cleaned. So there is a trade off you have to make.
Here are my suggestions for where to use each sheen but you can usually get away with a sheen above or below what I suggest here as well.
- Flat/Matte – Interiors, ceilings, walls (not in children’s rooms)
- Eggshell – Interior walls
- Satin – Exterior walls and trim, kitchen & bathroom walls, interior trim & woodwork
- Semi-Gloss – Interior trim and woodwork, windows, painted floors
- Gloss – Doors, windows, interior trim
5. Paint Better With Additives
There are two main additives I don’t paint much without. They are Floetrol (for water-based paints) and Penetrol (for oil-based paints). These additives slow down the drying time and thin out the paint just enough so I can get a nice smooth coat without brush marks.
They’re usually not needed for walls or ceilings, but when painting windows, doors, and trim they are a necessity in my opinion.
6. Paint in the Right Weather
It doesn’t have to be perfect weather to paint, but painting under the wrong circumstances will ruin what would have otherwise been a perfectly good paint job.
Here’s a little painter’s joke:
A painting crew is on the last day of the job painting a huge church. The last piece they have to paint is the top portion of the steeple. As the crew gets closer to the end they notice that they are running low on paint and likely won’t have enough to finish the job.
The supervisor, noticing the approaching rain clouds, decides he doesn’t have time to run to the paint store before the storm hits so he instructs the crew to thin the paint down to help it go just a little bit further.
The crew is a flurry of activity to thin the paint and get the top of the steeple finished before the storm hits. Just as the last remaining brush strokes are applied to the steeple the sky unleashes a torrential downpour and the thinned paint begins running off the building. Just then lighting strikes the steeple knocking the supervisor down to the ground. As he slowly picks himself up off the ground he hears a booming voice from above say, “THOU SHALT NOT THIN!”
Nothing better than a little painter humor! Seriously, though here are some simple rules for when to not paint. Any other time is just fine to break of the brushes and climb that steeple.
- If the paint won’t be dry to the touch before rain hits
- Above 95°F or below 55°F
- On a wet surface
- On a dirty surface
- On windy days
- In direct sunlight (if at all possible)
- During a hurricane, tornado or when your wife tells you otherwise
7. How to Stop Sticking Paint on Windows and Doors
When two painted surfaces stick together that is called “blocking”. It’s not only annoying, but it ruins plenty of nice paint jobs. This wasn’t so much of an issue until the introduction of water-based paints.
Oil-based paints, once dry are very good at preventing blocking. Water-based…not so much. So what can you do?
Well, for starters you can use oil-based paint on windows and doors. Sure the drying time is a bit longer but you won’t have sticking doors for the next 20 years.
If oil-based isn’t the way you want to go then you can also wax a door jamb or window jamb to help prevent the blocking. Look for any areas that may touch when closed and after the paint has had about 24 hrs to dry you can add some beeswax or finishing paste wax to the those specific spots.
You can also remove any weatherstripping for the first month while the water-based paint cures. Then re-apply afterward when the chances of blocking are greatly reduced.
8. Don’t Paint Silicone
If you want to make a mess and watch paint completely refuse to stick to or dry on a surface then by all means paint something silicone. Paint will not adhere to silicone…period. Spray paint, primer, oil-based, water-based. Not nothing.
Bottom line, if it’s silicone caulk, or weatherstripping or silicone anything, don’t try to paint it.
9. Clean the Surface First
If you try to paint a dusty, dirty, wet, oily, or otherwise soiled surface your paint will likely not adhere well. Wash the surface first to prepare for paint. If it is greasy or soapy like kitchen and bathroom walls can get then scrub the surface with some TSP to clean and degrease the surface.
Once the dirt or residue has been removed then you’re ready for paint.
10. Prime, Prime, Prime
If you’re wondering if you need to prime a surface first the answer is probably yes. No, you don’t have to prime every surface every time, but it is never a bad idea and it provides that extra security you want.
Priming when changing from oil-based to water-based paints or vice versa is imperative. Priming bare wood is always important.
There are a ton of reasons to prime and the only reason to not prime is the added expense and time. If time is a concern then you can always have your primer tinted to the new color you plan to paint thus helping you get faster coverage.
[Tweet “Priming solves the problems you didn’t know you had until after you paint.”]
I hope this answers some of your questions to help you paint better. I’m sure it will because I get asked these all the time. Now there is no excuse to put off that painting project any longer.
