The Mordant Active Stain Concentrates are special liquid stains in aqueous solution for the colouring of wood by spray or brush, for the positive effect stains. They allow to obtain strong highlighting effects on the grain of conifer wood. Used in combination with the waterborne Borma mordant stains' binder TP1050, they have an excellent positive power, and their colour is lasting in time. The treated supports once dry can be easily overpainted, treated with oils or waxes. Following the Borma Coloroil System suggestions, it is possible to reproduce all of the colours of the Borma Wachs colour folders.
