Reality check!

I completed this painting on July 30th of this year. I was up close to it the other day and noticed this! :o

Right now it appears to only be this small area of the background, but seeing that it has only been a few months I am guessing that I can expect to see it happen more as time passes on.

Now I know that I need to learn all the measures to take to make sure that this does not happen again. I checked all of my other work, and no other paintings appear to have any cracking.

As for this one... is this cracking, or delaminating? What can I do to fix it?

Here are the stats: painted on a pre-stretched, pre (acrylic) primed canvas using paint and Liquin only.

Lacey,
I heard that Liquin and such can cause a delamination. Personally I don't use it as it darkens too much and I can't stand the smell of it.

Lacey,

This look like crazing to me. It occurs when the surface paint has less elasticity than the underlying surface. This sometimes is a lean over fat phenomenon in which a paint with a low oil content is placed over a high oil content film. Crazing can also occur when the paint doesn't properly bond to the under-painting. Unless you plan to scrape the paint off and redo it, I wouldn't worry about it. Many old masters have the same problem.

Thanks Richard... I have never heard of "crazing." Maybe we could have a dictionary in this section that covers words like crazing, delamination, etc?

I guess that I will wait and see how much of this occurs and over what areas before I decide what to do about it. It would be quite annoying to fix up one area only for it to spread.

Hi Lacey,
Craze is by definition a fine crack in a surface or glaze, and Richard is right, it looks like crazing.
If you paint "fat on lean" it will prevent such problems. But if it is already a "lean" coat of paint, probably it is the Liquin or maybe the paint itself which has fillers in excess that can cause this.
