Painting Wood Signs

Painting Wood Signs, in general, seems difficult so I decided to do some research on it. Being new to painting signs I was wondering what are my options? I knew I didn’t need to be an expert but wanted to ensure I wasn’t wasting my time or money, but yet still get the look I was wanting.

The Best Ways To Paint Wood Signs are simple. Consider the look and feel you are going for. Utilize an Acrylic or Latex paint, the color of your choice, then with a small paintbrush or sponge applicator spread evenly across the wood sign, typically going with the grain. Let dry and repeat.

During my research most of the articles and YouTube videos I saw referred to painting the letters of the wood sign versus general painting. So I wanted to give you more information to help you out with general painting.

What Will You Need To Paint?

The supplies you will need are basic and not very expensive. If you are on a budget then this will work for you.

  • Small Roller – You can use a standard house painting roller which are 9 inches wide if you have them around the house from another project. However if you want to put out a little money the preferred size is 4 inch wide roller.
  • Roller Cover – There are several roller covers to choose from. Your generic Synthetic Roller Covers are a great choice. They include Polyester, Nylon or Dacron.
  • Roller Tray – You will need a tray to roll the paint from and apply to you wood sign. I recommend getting a tray for the 4 inch roller and then wrapping it with a plastic bag or tinfoil prior to pouring the paint so you can use it again.
  • Sanding Blocks – You will need both medium (120 Grit) and fine grit (240 Grit). An alternative is sanding paper if you have them around from another project.
  • Flat Surface – A table in the garage that is flat is the best place to paint your wood signs. This keeps the paint even while drying.
  • Cover On The Table – An old sheet or old towels work perfect for protecting the table or flat surface you are using from any spillage which may occur.

Ensure you paint your wood signs in a well-ventilated area, preferably outside on a patio or yard if possible. If that is not possible due to weather or the temperature, the garage is a good place where you can open a window to ventilate any fumes which come from the paint you are using.

Additionally – If you are going to paint in a closed-in room I would suggest a mask to alleviate any fumes you may encounter.

What Kind Of Paints Do I Use On Wood Signs?

Depending on who you research you get varying opinions on what kind of paints to use when painting wood signs. Since I was looking at painting in general, not lettering, I had a hard time finding information. So I have compiled a list below to help you in your effort.

There are many things to consider when choosing your paint for your wood sign.

  • Wood Type – Different types of wood accept paint in different ways MDF, plywood or pine and walnut for example. The main point is to consider what paint do you want to use. Most applications will use Acrylic paint with no issues.
  • Varied Color – This is important to consider especially if you have a specific color to match for a logo, business wood sign or you have a specific color you are look to match.
  • Can you mix or lighten – Most of the paints I researched have the ability to be mixed to lighten to color variations, however some don’t – Be sure to look when you pick your paint or consult the salesperson or website where you are buying your paint.
  • Drying time – If you are on a timeline you need to consider the time it takes for your paint to completely dry. For most paints (Acrylic and Latex) the drying time is about 4 hours. Oil paints on the other hand take up to 24 hours.

Lastly, I want to mention, if you choose an Oil-based paint ensure you look at the implications of Volatile Organic Compounds (VOCs) and effects of polluted air, inhalation, and poisoning. If you would like more information on this subject you can go to this reference. “The Health Effects of Oil Based Paint” on the Livestrong website.

How Do I Paint Wood Signs?

Painting your wood sign is quite a big subject so I decided to narrow it down to the basics. What are the basic steps I need to know? The list below considers the fact that you have already chosen your wood. For this list, I used common pine 12×12.

  • Sand your wood sign with a sanding block(s) – preferably a medium grit to start. Then go to a fine grit sanding in the direction of the grain. If you have a sander that would be preferred. Use an 120 grit to start with and then use a 240 grit sandpaper on your sander to finish.
  • Do you want a Rustic Wood Sign look – If you are going for the Rustic look the start with the Medium sanding block or 80 Grit Sand paper. Sand a little but not enough to make the surface completely smooth.
  • Wipe your board with a clean cloth or microfiber towel. This ensures the board is clean with no dust to clump up in the paint.
  • Paint a primer paint – It’s always a good idea to paint a primer on a plain wood sign prior to the final cover. Please consider this step even though the final color choice you have states the paint includes primer.
  • Paint the Final Color – If you are going for a single color paint the final color on the primer from the last step and let cure for 24 hours. Despite the 4 hour drying time of Acrylic/Latex paint I recommend 24 hours. This makes sure you have a completely dry and durable surface to create your wood sign design. If you are going for a multi-color background then ensure you completely let dry prior to taping off the section which needs the additional color.

Is There A Difference Between Indoor And Outdoor Paint For Wood Signs?

Before we get into the specifics about indoor/outdoor painted signs what is the difference?

  • Indoor Paint – Indoor or interior paint for wood signs are meant for resisting staining and can be cleaned easily. It is not meant to confront the harsh outdoor elements.
  • Outdoor Paint – Outdoor or exterior paint for wood signs are meant for the harsh outdoor elements and against fading and mildew.

Now we know what, which is the best paint to use? In my research, I have found latex to be the best paint for painting wood signs. The solution provides enough protection for both environments, color choices and is very easy to work with.

However, please note that maintenance will be needed no matter what paint you use especially if you place your wood sign outside. If you want to place your wood sign outside it is recommended that you seal the wood sign with a sealer (Polyurethane).

If you seal your wood sign it will resist the fading and elements of weather better, but still would need to be re-sealed approximately once a year depending on how long you leave it outside. Most folks who have wood signs for home decor only place their wood signs outside during good weather or to celebrate a family event. The other alternative is to place under an overhang which does provide some protection from the Sun’s UV rays and inclement weather to a certain degree.
