Thank you for the recent info + quick delivery of the mortar tinting kit. Very pleased with the results, see attached pictures. The ugly repointing is gone!I used an undiluted mixture of lightener + a small amount of the yellow stock and rustic brown. Takes a few tries to get the right colour match, but not too difficult. The mortar brush was just the right size, it would've been a much more difficult job without it. thanks again! Barry S, Wokingham, Berkshire.
