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
