This is an oil painting on a piece of wooden board. The wood was exposed to moisture and horizontal cracks started to appear, in line with the grain of the pressed wood. Some cracks were a bit wider, even causing the paint to flake around the roof area.
Firstly, the work was cleaned. After that, I filled in the missing paint around the roof area with a gesso chalk mix. I layered the mix until the desired thickness was accomplished. Then I painted over the gesso mix with acrylic paint. I also filled in some of the horizontal cracquele and sealed it by giving the piece a mat new lacquer, keeping the paint sealed and the painting protected.
