Do not activate the trigger guard until after you have started your movement and release it before the end of the movement. This will avoid excess varnish application at the spray points at the beginning and end.

What is varnish made of?
Varnishes are made up of volatile solvents and aqueous materials . Varnish is based on a solvent and binding agent. The solvent evaporates during the drying process and leaves behind the non-volatile components as a solid film. The binding agent ensures that all components combine to form a homogeneous mixture, guarantees bubble-free drying and is also responsible for the shine after drying. Other, non-volatile components include pigments, oils, resins, fillers and additives. The pigments provide the colour while resins are important for the varnish's adhesion to the base and producing a glossy finish. Often, calcium carbonate, barium sulphate or kaolin are used as fillers and help to adjust the degree of shine and surface structure, as well as acting as pigments providing colour. Additives are auxiliary ingredients that are added for specific extra functions. These might be biocides, for example, which prevent the formation of micro-organisms and therefore give the varnish a longer shelf life.
