When it comes to using canvas as your support for an oil painting, what is usually borne in mind is to achieve an excellent and permanent art piece that can last for an adequate period of time. However, canvas of various textures, weight and types are utilized. While some of these canvasses are primed, some are not., and while some are absorbent (suitable for a permanent finishing) others are non-absorbent.
In consideration of all the above qualities, painters no doubt choses canvas that aids the free and smooth flow of the oil paints, absorbs the paint and ultimately dries to achieve a permanent piece e.t.c more than any other type of canvases.
Non-absorbent canvas is largely unsuitable and unprefered in oil painting., reason being that they are usually heavy or thick, doesn't absorb paints and it disposes paints to rub-offs. But I want to convince oil painters that Non-absorbent canvases can be made use of, albeit certain steps are to be taken to make your work permanent and rub-proof.
Below are the steps I took to achieve this:-
1. Frame your canvas before use.
2. Begin your painting process, but ensure that your oil paint is thoroughly thinned down using linseed oil or any other thinners. e.g. kerosene.
3. After the painting process, place in the sun to evaporate and dry off. This will leave the work powder-textured when felt or touched, but willn't blow away.
4. Using Glue or adhesives that becomes transparent when dry, apply first coating over the piece.
5. After the first coating, place in the sun to dry.
6. When dried, apply a second coating., and leave to dry.
7. Congrat! your work is now rub-proof and permanent. You can now make use of all your Non-absorbent canvases, enjoy yourself.
N.B: Your coatings must be light. Do remove brush hairs that are detached during the coatings as attempt to remove them when the glue has dried will cause peeling off of that area.
