Acrylic size

Sizing minimizes the penetration of the priming and paint layers to the back of the canvas -making the canvas impervious before applying primer Hydro Sealer is used for sizing or preparing substrates ranging from moderately porous concrete to highly absorbent sand plaster before applying acrylic colours. painting_materials_lascauxproduct_size

Acrylic Size

Lascaux  Acrylic Size Plextol D498 The above are two examples of synthetic materials that can be used in place of animal based sizes. Although they are intended for use in acrylic based systems they can be used in conjunction with commercially produced oil primers although it is advisable to use acrylic primers over acrylic sizes. PVA is prone to deterioration and should be avoided. Acrylic priming systems are easier to use; unlike traditional materials, their properties are predictable, strengths do not vary from batch to batch and the entire process is speeded up.  


  Egg / linseed oil emulsion Ground for canvas and panels I Egg Raw linseed oil Water Titanium white (or other) pigment Rabbit skin glue solution (1:30, glue to water) Sized panel (1:15 solution) or sized linen (1:30 solution) Break the egg into a glass jar and shake. Mark the level on the side of the jar and double the existing level with the oil. Again mark the level and double the quantity with water and shake to form an emulsion. This will store for 1 week in the fridge. Put some Titanium white pigment onto a glass slab and Read more

Surface Preparations

Chalk ground for panels   3 parts whiting 1 part Titanium white pigment (Optional) 3 parts glue size (1: 15 water)   Sized panel (1:15 solution)   On a glass slab form a well in the centre of the whiting and add the glue size, gradually folding in the powder and work with a palette knife until a firm but glossy paste is formed. If the mixture is too dry it can be adjusted with a small addition of 1:15 glue size, if too wet a small quantity of whiting can be added. The stiff paste can be stored in Read more
