Until I watched Countryfile on Sunday and heard John Craven talking with
a company in Wales who make lime mortar and run courses etc., I was going
to repoint my 150 year old end terrace with cement. I think I have lime
mortar since it's a magnolia/yellowy colour.

I need to repoint inside and outside. Inside the plaster has blown and
the mortar is very crumbly. Was planning to

rake out old mortar
cover wall with cement render, pushing render into the joints
cover with insulated plasterboard.

If I need to avoid cement where can I get lime mortar.

Thank you,

Neil

You mix your own with cement and lime and sand. The proportions will depend
a bit on the sort of wall and property you're dealing with.

One suitable mix might be 1 lime, 2 cement, 9 sand by volume. Brickies might
dispute this, or have other ideas.

You can buy hydrated lime at any builders merchant.

I actually have used a mix with about 4 sand to one cement and one lime.

Its proably completely wrong
