I talk a lot about wood signs around here, in fact my most popular posts and videos revolve around them!  Today I’m answering the most asked question I get related to wood signs; how do you seal a wood sign?  The answer depends on a number of factors so I made a video that lays out a few different scenarios and how you should go about sealing your painted wood sign.

When I first started making and stenciling wood signs I never thought to seal them. I figured if I used the right stain and paint, and they hung on my wall inside there was no need to stain a wood sign.  But after making videos and writing posts about these signs everyone wanted to know to seal them.  So I did some research, and tested products and came to my own concrete decision. 

Ready for it.

I do not recommend sealing decorative painted wood signs that you display indoors. There is just no need.  A sealer is made to protect the wood and your art, but a good stain and paint will hold up for many many years indoors without any sealing. 

So, when do you seal a wood sign?  

I recommend sealing signs that will be kept outdoors, or exposed to the elements on a regular basis.  Sun, wind, rain and snow will wear down your art and deteriorate the sign.  

Now that you know when to seal a sign, let’s talk about how to do it. Be sure to watch the video for all the details, you can find my tips below as well. 

3 ways to seal a wood sign

These are the 3 products I reach for when I need to seal a wood sign.  

For all of these products, make sure the stain and paint are completely dry.  Wipe any dust with a soft cloth and apply the sealer with a good quality brush.  Let it dry completely before adding a second coat if you choose. The products come in a variety of finishes from matte to high gloss, each will give your sign a different look.  

Polyurethane This oil based sealer is great to use over an oil based stain.  It does have a tendency to yellow the paint a bit which makes it ideal for warm colors and rustic looking signs. 

Polycrylic This water based sealer works best over water based stain and any kind of paint.  I like the satin finish and use this on most of my painted outdoor pieces. 

Spray Sealer This product comes in a variety of finishes and you can find it water or oil based.  I like to use this type for large outdoor products that are hard to cover with a brush. 

Creating wood signs is one of my favorite ways to craft.  If you create a sign that will be outdoors be sure to seal it using one of these methods.
