I have laid a 15x6ft area in the garden with grey cobbles and want to 'dry' point them with a similar colour. I beleive concrete colourants come in both liquid and powder form but want to point the cobbles dry. I have seen 'Biofix' but is expensive, can anyone advise what are the potetial problems of thoughly dry mixing concrete and powder colourant to use for pointing?
