Recommendation for lime /paint products

Hi we have just purchased a property of traditional construction. The pointing is mostly cement in place. There is a lot of loose cement and the house survey recommends that we repoint with a lime mortar as and when the pointing becomes loose. I have uploaded some pictures to give an idea of the stone and current cement mortar. I intend to repoint with lime as and when cement becomes loose. Can anyone recommend a suitable lime product? I’m thinking one that is a little in keeping with the cement currently there so the lime doesn’t stand out too much? Someone mentioned they use CLM 28 (coarse) and 35 (fine) .

Also it has been recommended to use a breathable paint. The current walls, and ceilings etc are traditional Laff and plaster. Everything is currently yellow so that needs to change. I have no idea if the current paint is a modern non breathable paint. There is no current damp. Therefore can you recommend a breathable paint range that would be suitable to paint over modern paint? I really don’t want to have to sand back!

Thanks mark 😊

Thanks for getting in touch.  We would suggest removing all the cement pointing and replacing with lime.  There are different options available – site mixing, where we sell the components – sand, lime and then you mix together yourself on site, we offer dry “just add water” products packed in 25kg bags in our Cornerstone range – this method means that you get consistency between mixes and we’ve done the gauging for you or alternatively you can point in either CLM28 (coarse putty mortar) or CLM35 (fine putty mortar).  If you can let us know your preferred method and the area in m2 we can give you approximate quantity advice.

We offer breathable paints – our Beeck Maxil Pro will be suitable to paint over existing surfaces and is available in over 240 shades, however,  it’s not going to make your walls breathable if there’s a modern paint underneath. – the only way to do this would be to remove the existing paint.  We also need to point out that any paint will only be as good as the surface it’s applied to so if there are areas that are flaking, peeling or bubbling this would need addressing before you paint.

If you need more information or would like to discuss in further detail please give us a call on 01208 79779 or email sales@cornishlime.co.uk and we can run through the options for you.
