If you need to fix your drawing, do not use ballpoint pens, felt-tip pens or markers. These writings aids will bleed or change the colour after the fixative is applied. Multiple application of the fixative or a thicker layer will make the drawing darker, with a result of more intensive depth. Where the fixative is applied on an uneven surface, the spray must be applied in multiple layers and in various directions to make sure that the fixative layer covers all surface of the painting.

Since the fixative can seep through if applied on a thinner base, a clean sheet of paper or cardboard should be placed under the drawing. The fixing process can be done in several steps. If you want to fix a finished part of your drawing, apply the fixative on that part and then continue drawing. It is possible to draw on the part of the drawing that has been fixed, but it cannot be rubbed out. The drawing surface can be fixed in several layers, but the first spraying must be left to evaporate and dry.
