How to prepare a canvas

The task of priming a canvas is essential for the painting is the desired behavior. Let's see how priming and preparing a canvas before painting our artwork.


How to prepare a canvas


The canvas is in itself the absolute foundation of all painting. A poorly mounted canvas could affect the final appearance of the most outstanding works of art, and an unprepared canvas could derail an entire magnificent creation in just a glance. Therefore, before undertaking the work of oil painting , learn to prepare the canvas in the most appropriate manner .

The canvas, or canvas, a frame structure is mounted with a special, very firm, and properly disposed fabric. 's very important that the primed canvas is found , so that the fabric will not generate an undesired behavior of the paintings. This is particularly important in water-based paints, which spread easily but is of outstanding importance in oil since an unprepared canvas could rot quickly.

The primer then allows the paint to properly dispose of the fabric, without spreading, but with a good adhesion. The easiest way is to do a canvas primed with rabbit skin glue, or with a mixture of glue called gesso (which is tail "rabbit" or carpenter, mixed with white, or chalk, or even plaster paris).

Such a mixture is prepared by mixing wood glue or "tail rabbit" in solid state, preferably, or in flakes. Equivalent to 3 tablespoons (80 grams) in a plastic pot is placed, and add one liter of water "to tail" (can be purchased at craft stores). Mix with plastic spoon. When you notice that the queue has been hydrated, and can be used. Let stand, and prepares a small metal pot or jar.

In this metal container will post portions of the mixture, and take the heat. Stir with a spoon or wooden paddle, so heat is properly distributed. Be sure to scrape the bottom and sides to prevent sticking and burning. The mixture should not boil at any time.

Then we prepare the glue by mixing it with gesso. To do this, do homework with tail "rabbit" and mix it with white (or chalk). The calculation is two kilograms of white, by the amount of previous preparation. Mix well and continue to give heat.

When completely dissolved, you can add a few drops of linseed oil to form a smooth, pliable dough. This mixture must be liquid and watery. We apply several coats of this mixture on the good smooth canvas, leaving dry properly between them, and let stand at least a day after giving the last layer. We must prepare the canvas indoors to prevent any dirt deposited breeze on the web or in the mix, both in application and drying.

This priming process may be effected on any surface, including wood, and even walls.
