If you paint with oils, how to do treat the canvas first and seal the painting when finished?

all streched canvases, or canvas boards are sold pre-primed for oil and acrylic painting. but if you are making your own canvas, all you have to do is apply 2-3 thin coats of acrylic gesso. another method of priming the canvas is to use oil primer. this method requires a coat of size, or thinned rabbit skin glue, before applying the oil primer. oil primer takes 3-5 days to dry, so it is much less popular.





for varnishing oil paintings, you need to wait A MINIMUM of 6 to 12 months for moderately THIN oil paintings. for thick impasto paintings, up to 2 years needs to pass before applying varnish. applicating varnish before the designated period of time will result in the cracking and possibly peeling of the paint. as for what varnish to use, i reccommend modern artist gloss or matt varnish made by winsor%26amp;newton. Unlike the traditional ketone and damnar varnishes, modern varnishes DO NOT darken with age and can maintain the vivid color of oil paint for a much, much longer period than the old traditional varnishes. plus, modern varnishes are much less toxic and stroong than damnar varnish which requires very strong turpentine to thin and remove from the painting.

If you buy pre stretched canvas it probably already has a couple coats of gesso on it. If you are stretching bare canvas, give it a couple of coats of gesso yourself. After the painting has dried six months to a year, give it a coat or two of damar varnish.If you paint with oils, how to do treat the canvas first and seal the painting when finished?
