When using theAllback Linseed Putty for glazing, save time by dusting putty surfaces with chalk, and proceed to paint immediately withAllback Linseed Oil Paint. There is no need to wait for the putty to be dry before painting. The chalk helps to stiffen the surface of the putty so as not to create brush marks.
To achieve an easily sanded high finish indoors on a painted surface, mix chalk with Allback Shellac Primer to the consistency of a thick, paintable primer. Thicken with more chalk to produce a strong, sandable wood filler for small cracks and holes.
