I have a stone house in Mayenne where the majority of the house was re-pointed when it was renovated in 2005. The survey I had on the house indicates that it was re-pointed with a lime mix and as there are a number of small patches that need doing, inside and out, I have been trying to create a mix to blend in. The pointing is not a single shade but is generally a sand/buff colour. Here's the problem. I bought a bag of hydraulic lime and have two sorts of sand. One, quite a dark brown/yellow and one a much lighter colour left by the original builder. However, whichever one I use, the mortar always seems to dry into a pale grey colour which is not what I'm after. I'm aware that there are dyes on the market for mortar but somehow I cannot see the original macon going to all that trouble. I am mixing my sand 3 parts to 1 part lime. I have tried 1:2 and 1:5 but I still end up with a creamy grey colour. Am I doing something obviously wrong or does anyone have any pearls of wisdom? I should probably qualify myself by saying that my building knowledge is virtually zero! Thanks.
