It is an excellent solvent for Gum Damar and other resins for making varnish. You may have read that only turpentine will dissolve these resins, this has not been the case for many years, so you can use it to make your varnish if you wish. Zest-it Brush Cleaner can be used to make a standard “5 lb cut” varnish and dilute it down to your required strength. However, we would advise using the same diluent for dilution as mixing solvents could cause your varnish to go cloudy. Use it to make a medium by mixing with Linseed Stand Oil and Cold Pressed Linseed Oil. Your painting medium will be easier to make up if you add the Oil to the solvent and not the other way round. Linseed oils are very viscous and it takes a decent amount of ‘agitation’ for the two products to mix thoroughly. Painting mediums can be a personal ‘thing’ and the ratio of the mix is not fixed. If you are unsure, as a suggestion, try a 50/50 mix and adjust the proportions from there.
Use it for cleaning oil paint, oil colour, oil bars, oil pastels, oil-based ink, wax-based products, Damar varnish and other oil-based products from your brushes, palette, painting knives, rollers and equipment. The Zest-it Brush Cleaner has considerable active strength, meaning it is re-usable many times for brush washing. After use, allow the residue to settle and decant off the clear liquid, this saves on waste and makes it economical in use.
Dispose of ‘paint sludge’ by putting it onto damp sand or soil in a container.
Do not throw the liquid or brush washings down the sink.
