Garden slabs pointing
rage707 Posts: 1
My garden slabs were lain in 2009 and nothing has been down to them since save me pressure washing them for the first time 5 days ago. The sand/cement mix between the slabs could do with topping up. Is there an alternative to sand/cement? Is there a very heavy sand I could sprinkle in that doesn't need mixing with cement since I'm just "topping up" to prevent water getting down there?
The pointing they used was a mix of crushed black granite (plenty of other colours available) with a linseed oil based binder. I don't know what it's called though.
It looks great.
The only niggle is that after prolonged summer rain algae filaments (blanketweed) start to grow from it, but easy to brush off.
Wisdom is not putting it in a fruit salad.
I think its worth having a go with the sika but it need around 10mm of depth in the joints if I remember correctly to work properly
