david Posted February 1, 2009 Share Posted February 1, 2009 We are pointing our cottage and adjoining barn ourselves. At the speed I'm progressing this will take many years! I found it relaxing and rewarding until we bought more chaux ( St Astier) , We ensured it was with the same batch number as the sac we had commenced with but the colour does not match with previous pointing.We are not mixing with sand.Any ideas where we are going wrong? Do the batch numbers change annually perhaps...?? Do we have to buy all the chaux at once...?Thankyou in advance, David Link to comment Share on other sites More sharing options...
Dog Posted February 1, 2009 Share Posted February 1, 2009 Have you considered humidity?I don't think people 300 years ago would be bothered the colour. Link to comment Share on other sites More sharing options...
Théière Posted February 1, 2009 Share Posted February 1, 2009 [quote user="david"]We are not mixing with sand.[/quote]Then what are you mixing it with?(first person who says a trowel gets a slap)It will look different until it dries. Link to comment Share on other sites More sharing options...
BIG MAC Posted February 1, 2009 Share Posted February 1, 2009 I am trying to imagine what you could possibly be doing does the mortar come ready mixed with sand? Link to comment Share on other sites More sharing options...
WendyG Posted February 1, 2009 Share Posted February 1, 2009 Think you will probably find it will eventually dry out the same colour.At this time of year it takes a very long time to finally dry and needs the sun on it.Good luck Link to comment Share on other sites More sharing options...
pachapapa Posted February 1, 2009 Share Posted February 1, 2009 The temperature is too low for working with lime; below 10-12°C you are wasting your time. So what are you using instead of sand? Link to comment Share on other sites More sharing options...
Mutiara Posted February 2, 2009 Share Posted February 2, 2009 I suspect that maybe the OP is not actually using pure chaux, but one of the ready mixed derivative products "pret à l'emploi " made by Saint Astier, specifically for pointing/rendering ? I hope I am right otherwise he could have a problem [:)]Other manufactured products made for pointing that contain Chaux are made by Weber and Broutin and Lafarge ( Parexi) etc. Link to comment Share on other sites More sharing options...
Théière Posted February 2, 2009 Share Posted February 2, 2009 I do hope the OP is not one who starts a new thread then goes away for for a few days leaving people to hijack the thread and get into all sorts of cross words with each other, [8-)] Link to comment Share on other sites More sharing options...

david Posted February 2, 2009 Author Share Posted February 2, 2009 Thanks everyone for your comments!!! Obviously my explaination was not clear.We were advised by a chap who makes a living out of pointing to buy St Astier ( a ready mix specificately for pointing ) and mix with water until consistency of toothpaste. All very easy .Also easy to apply with the 'icing bag 'method.We are perplexed and frustrated that on buying more, with the same batch no., that the colour is not matching. I was just looking for any suggestions as to why this is the case .I'm trying to save time so can get on with the job when in France at Easter.Regards, David Link to comment Share on other sites More sharing options...
Théière Posted February 2, 2009 Share Posted February 2, 2009 Hi David, thanks for clearing up the sand question. St Astier make lots of different products, its sounds silly but have you bought the identical product or another one made by St Astier by mistake although the batch numbers may match?

master of none Posted February 2, 2009 Share Posted February 2, 2009 Although it was not a preparitory mix, during the summer my brother and I mixed a batch of sand/lime for pointing, we both worked from the same batch mix and when it dried his work was VERY noticably whiter than mine, reason being, he worked his mix/pointing technique more than I did. Overworking brings the water/lime to the surface, makes it whiter on drying and weakens the morter. Maybe this is something that you are experiencing?
