How to Get Rid of Bubbles Under Mounted Canvas Mural

October 7th, 2008 · No Comments · How To, Q&A with Michael

Question:

Hey Mike,

How you doing?  I’m happy to say that this year my business has taken off and I’ve been working onsistently since January.  Yay!  I just finished installing my first mountable canvas mural yesterday, and everything looked great, fit great, but I have a slight problem and was hoping that you might have a suggestion.

Everything was smooth on the wall, but as it dried, a few small bubbles have appeared today. They aren’t super noticable, but nevetheless I want it to be perfect. In your many years of doing this, have you ever encountered this problem? If so, is there a solution?

Looking forward to hearing from you.

Karen
p.s. Tell your lovely wife that I actually made 5 cold calls today, & on a Monday no less, in honor of her.

 

Answer:

Karen,

Great to hear from you and glad you’re busy!

I would think that the bubbles were there yesterday, but you just didn’t notice them. When you’re wiping down the surface with a damp sponge, it’s glossy, and sometimes unless the light is right you’ll miss some small bubbles. If they are close to the edge, just peel away the canvas from the wall and re-paste the area, smoothing it down good and tight.

Use a seam roller if you have to, wiping away the excess with a clean damp sponge. If the bubbles are in the center, then use a new and VERY sharp snap blade, slice a line in the mural over or close to the bubble, preferably along a painted edge or line, and insert some paste. Smooth it back out, and you should be good to go. I’ve actually cut a small slice in the canvas and inserted paste with a syringe. That works, too.

Or just paint the whole thing over again.

Just kidding.

Keep up the cold calls!

Mike
