Question: What oil cracking causes?I am working on an Oil Painting. I paint in the garage, it's summer, and I live in Florida, so hot it is there, as a rule, so I was a fan I have a few cracks in the paint, noticed lately. Why is this so? Does it have with the heat or the air the fan to do? Should I in the painting after the painting, so it is not exposed to the heat? I also have the cracks on most of the parts that have noticed Umbra. Are the cracks have to do with the color of Oil Paints?
Answer: Umbra can be burned susceptible to cracks. The quality The color is a factor, but iit is for the so-called "subsidence" is known, while the paint dries to a dull finish, while painted in other areas with different colors will be more bright for the further surface. This is a problem because it is difficult to match colors on these layers. The matt surface changes the color so that the fresh wet paint will never match, and you have to guess either one or you need to fall in areas with retouch varnish (the best way to with this). Cracking can be caused by too much dry, to revive in a medium, or it may be caused by a weak foundation. The surface can lead to contain much oil, or are thicker than the subsequent layers. The surface change the physical composition, and it's like an earthquake. The outer layers may only place for a limited number of amendments to its founding. Fat over lean is follow a principle. The bottom layers are thinner and less oil. The subsequent Classes think that with more oil. This allows the lower layers dry faster, so the subsequent layers have a solid foundation to dry up. In the vicinity of Heat and humidity cause drying over direct heat and humidity factors in the cracking, you will see. Mold would be a matter of time. The Old Holland brand of Burnt Umber is the least vulnerable to subsidence and cracking. Follow the fat content is usually slim. Try to use less Burnt Umber and mix into other colors. Save Your work in a cooler, drier, more stable region and without direct sunlight. All of this helps with these issues. https: / / www.aswexpress.com/art-supply/catalogs/0040544000000
