Hi all,
I have recently had Bradstone Panache smooth flags installed as a patio in our back garden. We also have some bradstone panache 2 years old as a path.
Whilst the flags are close together and on a solid bed so won't move and weeds won't grow upwards we are keen to avoid weeds/grass blowing down the cracks (as has happened in a minor way with the 2 year old path) .
joints are between 1mm and 6mm
What should I use to fill the cracks? I was recommended kiln dried sand as an option? and then marshals key bond to set, however marshals website says not to use key bond on flags?
i'm also tempted to use resi block to seal the flags, what are thoughts on this?
having looked at other posts on this site I haven't been able to source some of the recommended products so would be grateful for recommendations of products I can buy as a non trade customer.
