Should I Apply a Sealant Over My Decals or Stickers


Have you wondered if you should be sealing their decals?  Customers occasionally question applying a sealant when applying decals to a board or tile and want to make it last for many years.  Here we have a little info about decal stickers and polyurethane.

If you are ordering a wall decal, it should be a matte finish and the adhesive is not super strong (to allow you to take it off without ruining your painted walls).  Here is a picture of what can happen if you apply a thick coat of polyurethane over a wall decal sticker.

Polyurethane can cause the edges of the decal to curl. Now I am not saying you CANNOT seal your decal sticker.... we have had customers apply a sealant without any problems.

Here is some things to consider:
If you have a Wall Decal (matte finish and not super-strong adhesive), use a VERY light coat of polyurethane.  Mod Podge is another product that I have heard customers state they have used over their wall decal stickers. The polyurethane tends to curl the edges of a decal sticker and with the lighter adhesive, the strength of the adhesive can break down.... on a Wall Decal Sticker
Another factor on the above board might have been the seams of the wood - this allowed the polyurethane to seep under the decal sticker just a bit and this reacted adversely with the adhesive on the decal sticker.

When our customer sent us this photo with "Help!" as the subject line, we suggested we get her another decal (we generally offer a mess-up decal replacement at half price).  The second decal sticker would be made with the GLOSSY OUTDOOR grade material, though.  

The glossy was not a factor since the polyurethane she added made the decal glossy-looking anyway.  And our outdoor grade material has a MUCH stronger adhesive... once the decals sticks to a spot, there is very little chance you have to pick it up and move it to the correct spot!  So the stronger adhesive of our Glossy vinyl material was a much better fit for this project. The strength of the adhesive allowed for a strong application to the wood and therefore wouldn't curl the edges of the decal, when a light coat of polyurethane was applied.

Generally a sealant is not needed for a decal made with our Glossy outdoor grade material, but if you want to feel safer, go ahead and apply a coat of sealant or polyurethane over your decal, but, please, make it a LIGHT coat! The beanbag toss board picture below is an example of using a light sealant coat over our decal stickers.
