Working with an Unprimed Linen Canvas: Many artists enjoy the challenge of working with unprimed linen canvas. They take pride in stretching and priming their own canvas in preparation of creating artwork. Unprimed linen canvas provides a superior surface for priming and painting. It offers durability. This type of canvas is less likely to crack through the years like many others. Accomplished artists are more likely to prime their own canvases. This tends to take experience and practice for many. There are some basic tips for those who wish to prime canvas.
In the following are some briefly detailed suggestions:
A clean wide brush should be used for applying the primer. You can use a cheap decorating brush. This type of brush will need to be wash before use. The brush hairs often fall out of cheaper brushes. Washing a few times will often get rid of these loose hairs. To thin a brush you feel is too thick, simply use scissors and cut away some hairs. Older clean brushes are ideal for primer application. They generally have no loose hairs as they have been used before.
Your canvas will be smoother if you sand it between layers of primer. This also saves on the amount of primer you will need.
Always try to use a gloss medium for thinning your primer. If you use only water, there will more than likely be some cracking.
When applying primer, remember to start at the top of your canvas and work your way down. Use strokes that extend from one edge to another.
Never apply a second coat of primer until the first has been allowed to dry thoroughly. This will make for a rough surface that may be difficult to use.
As soon as you are finished applying the primer, you should always begin to clean up your brush immediately. Primer dries rapidly. Brushes that dry with primer in them will not come clean.
