Discuss Purbeck stone grouting in the Specialist Tile -Stone, Porcelain, Glass area at TilersForums. The USA and UK Tiling Forum (Also now Aus, Canada, ROI, and more)
I’m currently on a project using 20mm purbeck stone the field tiles are 435x435 with a 3mm joint.
the architect Has specified a lime mortar grout.
I have used a nhl-5 and sand mix to grout before as the floor was breathable the tiles had 6mm joints though.
This floor isn’t a lime screed so doesn’t need to be breathable.
I would much rather use a modern cement based grout so I’m going to try and convince the architect it’s the route to take.!
most architects I have come across live by their specifications so I’m guessing he will stick to his guns.
Has anyone else had success with a 3mm joint in lime mortar?
I’m really after as much info as possible - to either support my case for a modern grout or to reassure me his spec will be fine

I must bow to my elders on this one, never used lime mortar just sand and cement, grout was mainly pure portland cement with the odd handfull of sand thrown in. Over to you John, maybe
I’m not sure if they can help in this situation but I spoke to a company called Stone Tech from Middlesbrough when I repointed a section of my house with lime mortar, they were very helpful.

Don't mind me while I bump up some older but good threads. If you can contribute to the thread, go ahead. But if it's nothing for you then don't reply and it'll soon drop off the What's New page etc.
