For starters, responsible approach to the selection of material for the canvas different materials in different ways are primed and also have different effects on the texture of the future picture. Do not buy rare canvas and very thin cloth (calico, cotton). The most successful variant is to buy hemp hemp canvas and linen.
Buy fabric medium thickness and a sufficient density for successful gluing. Canvas should not be too rough and too smooth.
Stretch canvas on a frame, make sure it does not bend and did not warp. A stretched canvas should be elastic and durable, it needs not to cave under the brush and not get wrinkled.
Start the stretch of the canvas with fixing the corners on the stretcher temporary nails. Then fixate the Central point of the four sides of the canvas first short side then the long.
Stretch the canvas canvas from the middle to the corners, and only once the stretch is strong, finally hammer the studs in the subframe. Use conic furniture nails and drive them to the subframe in a staggered manner to prevent the cracking of the subframe.
After stretching the canvas get temporary nails, and glued the canvas to make it airtight and to close the pores and holes in the fabric. Sizing prepares the canvas to the primer and insulates the tissue from the effects of oil paints.
In some cases, the artists stretched on a frame ready, store-bought primed canvas. In this case, it is impossible to wet the canvas before you stretch – primed canvas should be stretched dry.
For proper sizing of the canvas need to apply several layers of glue – from two to four, causing the protective film from one side or another. Use the adhesive solution 5%, with a gelatinous consistency.
Apply glue with a wide brush or spatula on stretched canvas, removing excess with a knife, putting it perpendicular to the edge of the canvas. The glue should cover the canvas, but not to penetrate it the opposite direction.
Dry the canvas after the first sizing at room temperature and retry the operation. Then sand the surface with sandpaper, smoothing it.
Continue to glue the canvas using liquid glue with a plasticizer (glycerin or honey).
After sizing start to Prime the canvas. Primer applied on canvas with a wide brush or wide spatula. Do not apply additional layers of soil on one and the same place.
Dry the first coat of primer, and then apply a second and third, if necessary, using liquid primer.
Dry the canvas and check whether its texture is uniform and smooth. Now your canvas is ready.
Canvas, stretcher, primed canvas. Canvas is an impact on the quality of the painting. It should be able to choose and to ground. Beginners are recommended canvas of medium thickness tissue. Primed canvas to oil is not absorbed into the fabric, the colors didn't juchli and did not penetrate through the pores is not the reverse side of the picture. The soil is the link between the canvas and paints.
Before you start to Prime the canvas, you have to choose. The choice of canvas, which is the basis, very important question, because if you take the substandard basis, it is well not sarantuya and also the type of canvas or other fabric (canvas, rahoi, canvas, calico and so on) will be along with the soil to influence the texture paint layer. You should not take a lot of time wash the old canvas, a canvas with rare binding, canvas, calico...
Advice 2 : How to Prime the canvas
Efficiently primed the canvas, as the guarantee of preserving the brightness of the colors and durability of the fabric. For self-priming of the canvas, the artist creates an ideal basis for future paintings.
The preparatory phase
Before you begin the priming of the canvas it must be stretched on a frame and secure using a stapler or furniture nails. The cloth should be tight and no SAG. Skilled craftsmen pull the canvas is wet, for added tension of the canvas.
Before priming the canvas you want to glue. The glue will prevent symptoms of primer and paints on the reverse side of the canvas. For the initial treatment of suitable PVA glue. If the canvas is chunky knit, the adhesive should be applied in a thick layer using a rubber spatula or palette knife.
The more dense the fabric (canvas, canvas) that can be processed with paste are homemade. For this purpose suitable conventional starch. In a pot of water is filled with so much starch to make a viscous mass, and is brewed to achieve transparency. Paste made of starch is applied with a broad hammers finishing brush or a clothes brush.
After complete drying of the glue must be sanded. Use fine sandpaper.
Compositions for priming the canvas
Primed canvas to save ink consumption, to facilitate sliding of the brush and to give the canvas a uniform color. Most often primed canvas in white. However, if an artist plans to paint a picture with a predominantly dark background – it can add in the ground color pigments to canvas any color.
Adhesive primer quite heavily absorb paint, brush strokes will be more bright and matte. Glue soil made from one part gelatine, four parts of chalk or whiting and 15 parts of water.
Gelatine soaked and boiled in a water bath, whiting or chalk is dissolved in water and injected into the glue, then add a few drops of castor oil as a plasticizer.
The emulsion primer is the most practical. The first stage of the emulsion preparation of the soil is the same as that of the adhesive composition. Then added to the solution of high-purity linseed oil or linseed oil and a few drops of an antiseptic (phenol). You need to pour the oil in small portions and intensively stirring the solution. A sign of the quality of the emulsion is the uniformity of the whole: should not be separated and float in the oil.
Oily soil are obtained by using special oil white. After applying several layers of white canvas is aged for a year and a half to consolidate the layer.
Apply dirt part should be a thin layer. Emulsion and adhesive primer was applied with a wide brush, oil – with a thin spatula. The movement should be along and across the direction of the threads of the canvas.
Drying the primed canvas should in a natural way in well-ventilated areas. You can't rotate the canvas to the sun or the battery.
