pachapapa Posted May 9, 2011 Share Posted May 9, 2011 Interior lime pointing is not always a success, too much of it can be overpowering; a lime "enduit" can give a lighter effect. Link to comment Share on other sites More sharing options...
cooperlola Posted May 9, 2011 Share Posted May 9, 2011 We used chaux blanc and sand, plus a little (less than 10%) ciment blanc, (although the latter is frowned upon by the purists but makes it stick more easily) plus a teaspoonful of washing up liquid per mixer full. Looks fab (well, I think so.)[IMG]http://i134.photobucket.com/albums/q103/cooperlola/limeplaster004.jpg[/IMG] Link to comment Share on other sites More sharing options...
crossy67 Posted May 9, 2011 Share Posted May 9, 2011 I have seen some sand a similar colour and texture to our render so that looks good. It's, as I am sure you all know, very difficult finding your feet in a new country, finding even simple information out is a task. We spent 3 hours food shopping because we don't know what we're buying, it took me 15 minutes to decide on a piece of meat, now I have to decide how to cook it.Come on Papas spill the beans, what did you seal stone work with that still allows it to breath? I almost totally new to this stone business. Link to comment Share on other sites More sharing options...

The use of a mixer is not recommended as the quantity and speed of application will mean that the hydraulic properties of the mix are lost, it would in fact be simpler to use a "chaux grasse" with a ciment blanc , as the mix will stick better. The washing up liquid will delay the take of the ciment blanc, the chaux is not relevant as the natural hydraulic will have been lost and the equivalent chaux aérienne will take years to cure. The lime-cement mix has been placed in the "combles" where one can assume that moisture in the wall is unlikely; particularly considering the pitch of the roof indicating the use of slates rather than "tuiles tige de bottes". I like the chimney, hope it has a traditional use and not a stainless steel flexi-pipe sticking out the top.[;-)] Link to comment Share on other sites More sharing options...

Thanks all for your advice.[/quote]Good move! he will know about local materials and their use. As has been noted above the colour is from the sand, but the sand grains must have no liant on them. if you use ciment blanc it cannot be easily removed and you will have the colour of the mix on the sand grains for the rest of your life. Artificial colours can be used with cement but they look dull and lifeless, particularly with lime. Better to use the colour of the sand, then second choice a natural colorant from the Rousillon area...ochres look well, a third choice is the use of a local clay in the mix but this will weaken the bonding of the mortar even with the addition of more lime in the mix and may retain water after rain, etc,etc. Be wary of "pierre apparente" as this is not in fact a pointed stone but a stone that has had the mortar removed with a sponge or a brush; this does two things it lifts the mortar from the edge of the stone allowing the entry of water from rain into the joints and it lifts too much of the lime mix covering from the portion between the stones. This reveals the colour of the sand but leaves insufficient binding support around the grains, resulting in the grains srting to fall out after the first frosts in winter and so loosing the desired colour. Got to go cut grass before leaving tomorrow. [:)] Link to comment Share on other sites More sharing options...
cooperlola Posted May 10, 2011 Share Posted May 10, 2011 It worked. I like the result. No damp problems 4 years on. Good enough for me.I had to bow to the builder's wishes in terms of materials as he was doing the job and he's a local who specialises in Percheron buildings. The washing up liquid bit amused me as personally it seemed a bit like a homeopathic remedy - far too diluted to make any difference whatsoever![:D] Link to comment Share on other sites More sharing options...

The Point P site invites one to a "devis".....seems a bit over the top for a 25 Kg sack, the contents of which will be 75% sand.[:)]But probably a good choice for a neophyte.

pachapapa Posted May 10, 2011 Share Posted May 10, 2011 The weber.cal F & G have the same composition: composition : chaux aérienne, faible quantité de liants hydrauliques, sables siliceux et calcaires, pigments minéraux.Have you any idea as to the nature of the "liants hydrauliques"?

bettyboop Posted May 11, 2011 Share Posted May 11, 2011 The weber stuff we use is in a yellow/blue bag,last lot we bought was in Toute Faire @ 12 euros for a 25kg sack, Point P was the first lot we bought but dearer 16e a sack. We have used it inside and on the outside.Hubby just mixes it with water,but not a lot, the longer you mix it the wetter it gets. Link to comment Share on other sites More sharing options...
