Why do oil paintings crack

Hi, I am an artist that works in many mediums but I just finished my first oil painting. It had dull spots and shiny spots. It has been over a week and it is still very very sticky.

Will it ever dry? Hi Susan, Thanks for writing. It will dry. It may take 3 weeks or more. Since this is the winter, it is likely cold where you live and this may slow the drying process even more. If is very cold where you live, bring the painting inside and it will dry faster.

Thanks again, Gary. Thank you so much!!! You made me feel better. It is a Christmas gift for my son. A painting of his daughter. I got the percentage of oil to turpentine from someone online that does a video about oiling out.

I use rather thin oil paint with a Grumbacher medium. I tried to start with the fat over lean idea but am never sure of how much medium to use at a time or how to control it.

I have several layers of paint on this painting because I changed my skin colors and shadows too many times. When I look at it the next day the surface is very blotchy and melds with previous layers of colors.

Please advise. I have just started with the wet on wet technique and wanted to know if once the painting has begun to dry and you have to leave it, can you later come back and apply some liquid clear and pick the painting back up? I have two paintings that I have had to leave and would like to be able to save them if at all possible. I have tried to find some answers everywhere I can think to look but so far I have been unsuccessful. Any help you can give me would be greatly appreciated.

In areas where you are painting over old spots, you may want to add a little more oil in order to allow for the fat over lean principle. This, however, is not a big issue unless you are painting in glazes and or multiple thick layers. Do keep in mind, however, that an alla prima painting is just that — done in one session.

Happy painting. Hi, I have an oil painting, and I used walnut oil as my medium. I noticed today when I checked my painting that the newspaper was sticking to the painting. Is there anything I can do to get the sticky surface to dry? Walnut oil like all the natural oils take a very long time to dry. It may end up needing a couple of months or more to dry completely. You can add Japan Dryer to your oil painting mediums to speed up the drying process in the future.

Be careful with Japan Dryer as it will burn the colors if you use too much. Your email address will not be published. Why do oil paintings develop hairline cracks and acrylic paintings do not?

If it is applied thickly, that is probably the reason for such cracks. Actually, if you could tell us everything that lies under this cracked paint [from the canvas, up], it would really help. Whoa, this is upsetting. I have never seen cracking like that in a painting.

So sorry. This will happen if you layer a faster drying paint over a slower drying paint. Did you use a different medium or less OMS on the first layer. What paint is this white layered over, is it a different brand? Yes, maybe the dark colored layer under was half dry when the top layer was put on, which then dried faster than the layer under. When the layer under dried, then the top layer cracked. Would be interesting hearing what paints and mediums you used, on what date.

This happened to me once, when I used a dark glaze with a lot of fast drying medium too much over a layer of half-dried paint that was fat much less medium.

I started thin, with no white involved. I used one thin layer of white gesso primer before that.
