I am used to painting our rendered house walls in the UK using Sandtex or Dulux paints. My wife has “suggested” that I should smarten up our old, stone cottage in France by painting the rendered walls. I do not know what the rendering is, maybe some traditional material, but I would like to use Sandtex paint. Is it possible that I could damage the render by applying Sandtex? The front of the house was certainly re-done about 45 years ago and looks rather like a modern cement based material. What other material could have been used?
I would appreciate any advice from members who have some experience or relevant technical knowledge. I need to visit Screwfix to pick up a 10l can next week so I can get the job done during our imminent visit.
Thanks

No you cannot damage the wall with using sandtex.

I used one of the variations that claimed to be breathable.
10 litres won't cover that much, no need to tell you how I know.

Thanks for the quick replies. I have also selected a breathable version. Landmannn, you are now required to tell us how you know, please! I hope to get away with a single coat so I was expecting to manage with just 10l

French stone houses are sometimes covered with a lime mortar, splashed on as crepe and is pre coloured. To paint over it would then give you a 5 yearly repeat job (sorry madam Lurcher) but I would personally avoid painting it. Clean it off with a karcher powerspray and anti lichen chemical. Modern newbuilds use a coloured product from Weber and our mason came with a massive book of colour samples to choose from for our work. If the render (crepe) is loose in places, a good mason will be able to repair it to a matching colour. Further discussion on this happened some time ago on another place www.angloinfo.com/poitou-charentes/discussions/home-garden/pointing-or-rendering-external-walls |

Over ten years ago when I bought this place I was faced with two walls of render that had never been painted. Appeared to be simple cement render, very grey and very dirty. I pressure washed them and when fully dry I applied a coat of a stabiliser solution to seal any porosity and bind any dusty areas. When that was fully dry I applied one heavy coat of a French product that contained an ingredient called Pliolite. I don't remember the brand but I have since noticed that many of the more expensive French products contain it. After all this time the walls might benefit from another pressure wash to remove a little dirt but the paint is still sound and adhering well.
I would never consider using a UK purchased product for exterior use in France. Sandtex is sold internationally but is formulated in a different way to suit "local" conditions. Bite the bullet. Buy French but don't buy the cheapest generic muck in a plain white tub on offer.

I think you should check with your marie in case there are any local planning issues concerning the colour.

I would definately use Sandtex or Dulux, there is another make called Granocryl made by Leyland paints which is much cheaper and does an excellent job, go for smooth rather than textured, you might of noticed new build rendered houses in France with reddish streaks on the wall, that is from minute traces of iron in the sand they use to add texture to the paint.
I pay about £17 for 5l Granocryl in the UK, look on Amazon.

At your own risk.
Roll the dice. If you're selling up soon and want to save money, go for it.

We are not trying to sell immediately but the main reason for painting the outside walls is to make it more attractive when we do sell in a few years time.We have lived with the rather rough appearance for 22 years and love it the way it is.
I have found a product which mentions pliolite from Bricomarche as described by Aadvark but is over 60€ for 10l. The colour is “ton Pierre” which is a deep cream, probably not to our taste. There are other colours available but in very trendy greys, white and black. I think that I will be taking our chosen Sandtex for £33 and hope it looks good for at least a few years.
It has been very helpful to receive good, practical help from the forum members. Thanks.
It was interesting to discover here why the red streaks have appeared on quite a few houses nearby.

Another option would be to spray a very light covering of sand and lime, very cheap to do and will last longer than any paint.
Webber and brouton probably spelt wrong to a wide range of colours.

Mysty is referring to Enduit Tyrolean, a good suggestion which will be the same chaux based material as the base enduit, you will need a crepinette and half decent compressor but the finish will be pro. Ton Pierre is supposed to be sandstone colour but unlike sandstone the colour changes according to fashion, it was once very yellowy and then went to an off white with no trace of yellow, unfortunately I was half way through my exterior at the time  For the facade which was WW1 reclaimed red bricks then slathered over with a red dyed mortar and false joints trowelled in which had faded to nothing over the decades I used the cheapest Brico-depot white Pliolite paint mixed with brick dust from the tronconneuse to get the colour and texture of the clay bricks, I rollered it on which gave a horrible pink shiny finish but when that was spread out thin with a dry brush it dried to a perfect colour and texture of clay brick. It has been up for close to 15 years now and looks even better now than the day it was finished. The smooth rendered horizontal bands which were to break up the facade and for the original signwriting I did with plain Pliolite Ton Pierre and that is now showing its age with discolouration from traffic dirt and rain. |
