A method of recycling waste emulsion paint for the manufacture of useable paint, comprising the steps of: (a) providing a paint precursor, comprising degraded paint; and (b) treating the paint precursor by: testing the pH of the paint precursor and, if necessary, adjusting the pH to lie within a predetermined range of 7.5 to 10; adding an odour-reducing material selected from clay, and/or talc in an amount of from 0.5 - 30% w/w; testing the viscosity of the paint precursor and, if necessary, adjusting the viscosity to lie within the following ranges, when measured using a Brookfield DV-II viscometer installed with a LV-4 spindle rotating at 0.6 revolutions per minute, for matt grade paint, from 5.5 × 10 3 centipoise to 13 × 10 3 centipoise, measured after the paint precursor is allowed to stand for 5 minutes and from 12 × 10 3 centipoise to 22 × 10 3 centipoise, measured after the paint precursor is allowed to stand for an hour; for silk/soft sheen grade paint, from 2 × 10 3 centipoise to 4 × 10 3 centipoise, measured after the paint precursor is allowed to stand for 5 minutes, and from 4 × 10 3 centipoise to 9 × 10 3 centipoise, measured after the paint precursor is allowed to stand for an hour; for an alternative silk/soft sheen grade paint, from 5 × 10 3 centipoise to 10 × 10 3 centipoise, measured after the paint precursor is allowed to stand for 5 minutes and from 10 × 10 3 centipoise to 15 × 10 3 centipoise, measured after the paint precursor is allowed to stand for an hour; and testing one or more of the following properties of the paint precursor and, if necessary, adjusting the property or properties to lie within a predetermined range: (i) specific gravity and; (ii) solids content, whereby the predetermined range for specific gravity is 1 to 2 and the predetermined range for solids content is 20% w/w to 55% w/w; whereby at least one of the pH, specific gravity, solids content and viscosity of the paint precursor is adjusted, thereby producing paint.
