What can I do to keep paint on the walls old coteco - Page 2

Thanks time. 

I’m going to pass on my builders’ methods:

Put on a plastic render, (plaste renovación) onto which you place a strip of nylon netting. Push to sink into the rendering then you put another layer on top and there you are, a good, uncrackable waterproof rendering. You can then paint over this with a waterproof paint (plástica pintura).

A whole wall can be rendered like this in a day but it is worth it as it will last. 

Good luck,

Thank you very much

We buy some stuff called capa fina - a white render stuff that has adhesive in it and use that - works better than paint. You can get at any decent ferriterias

You don’t really want to waterproof the walls as the stonework needs to breathe 

Better to scrape out the old mortar if there is any and repoint with a lime mortar then paint with cal inside and o
