.rising stains through stone slabs

I laid my own patio in silver granite 3 years ago no show yet. Hanson do silver sand.

I've used this stuff slurry primer recently on ceramic paving and it's the dogs proverbials. Why bother with an sbr slurry when this is available.

I know a lot of contractors who are using these primers now.

In the past we have advised clients to use river washed sand and white cement to reduce the chance of staining but its belt and braces and these types of products should negate the need to do that

Thanks for that. What is river washed sand otherwise known as ?
