What part of the country are you I'm north wales we have white soft sand I'd put that in to make a mix What ever sand you chose to use ide mix a sample first just mix a batch up using a small cup and mix your ratios the same

Lancashire and thanks pal I'll give it a go at home with some white soft sand then and see if it comes out the colour I'm after good thinking

Hi Glen the house I bought is early 1980's I believe, it doesn't need to be completely repointed, but there's a few missing bits/holes that need filling in, with your experience, would it be safe to say portland cement was used on a building this age and not lime? Cheers

Yeah most likely Unless it was built in a heritage, are and the specified lime Is the mortar grey in colour

What good is a listed building in a lost country?

Not sure what you mean with that comment

Its not easy finding the right sand. My local building merchants sells the perfect washed grit sand by the ton but doesn't sell it in 25kg bags, i then mix it with washed silver sand. I always dry my sand in a big bucket for a week or so by placing small tube heaters at the bottom of the bucket My college tutor said sharp sand is shaped like triangles under a magnifying glass & grit sand looks like round balls. I've never been able to get sharp sand & don't fancy traveling 100miles just to find out its not what I was expecting

Where abouts do you live I'm in noth wales I travel 25miles to get my sand I have 4 different sands I use So I buy it in tonne bags But 1 sand only comes in 25kg bags

@@GMTpointingspecialistsltd I live in a small town called Bacup in Lancashire. We have some amazing building here, mine is a 1870's 3 storey Terraced house which is flagstoned on ground floor and also flagstoned on the first floor with a stone balcony at the back

@peterjameswalmsley9185 sounds nice I lived in Lancashire for 18 years Have you not got a local quarry near where you live Find out what the sharp sand You like is called see what quarry it comes from and go direct for small bags

@@GMTpointingspecialistsltd yes we have a few quarries walking distance, my dad told me that alot of flagstones were shipped down to London to use there. He also told me that when the quarry was at its peak in business at least one person died every day, which is sad really Anyhow I will enquire more on the sharp sand. Thanks
