I have some big gaps in the pointing of my patio, probable caused by previous pressure washing (I now have a less aggresive attachment). Can anyone tell me what mix I should use, and with what if any additives? It was originally done with wet mortar, so do I need to do the same or could I pour it in dry and let the rain set it? I have a giant syringe-type thingy, made for the purpose, but are there any pitfalls I need to know about?
I deliberately didn't post this in 'Ask a Grandad', as I have no doubt there are some very handy grans out there too. All tips welcome please!
How will things change if our summers keep getting hotter
