Is it okay to use lindseed oil and paint directly on my canvas is that ok? how long to dry?

Helen Frankenthaler did it. But I wouldn't recommend it otherwise.





Paint it with 2 or three coats of gesso first. You don't have to sand each coat if you're in a hurry, but the goal is to get the gesso as smooth as possible.





Linseed oil takes three to five days to dry per coat, depending on 1) how much oil is in the coat (the first coats you put on should be mostly pigment, and each coat should have more oil in it than the last coat you put on) and 2) where the painting is while it's drying. Putting it in a warm, well ventilated area with lots of direct light will speed up the process a little. Boiled or polymerized linseed oils dry a little faster, but can be hazardous. Walnut oil also dries quicker, but can be hard to find in stores because it goes rancid. If you do find it, only buy the amount you need for the same reason.Is it okay to use lindseed oil and paint directly on my canvas is that ok? how long to dry?
Yes, but only if the canvas is prepared/impregnated for oil colors. Some canvases you can buy are already prepared/primed for oil or acrylic painting. If your canvas is bare go to a local art store and just tell them you want to prepare a canvas for oil painting and you'll get everything you need.





Oils usually dry for a few days , but that can change depending on how much linseed oil you add, the way you apply paint(thick/thin) and even the prime gesso you use to prepare the canvas. There are some liquids you can buy that quicken the drying (use them only if you are in a real hurry). Unfortunately I don't know how to say it in English, but go ask in a hobby/art shop they will know.
