Hi
I need some advice please.
I bought Sika setting sand for my block paving driveway, it's supposed to be swept in to the joints and then wet with water afterwards then left to dry, it dries rock solid so nothing can get through (weeds etc).
The problem is that an area of the driveway has white stains on it after the sand has dried, maybe some sand was left on the blocks which was supposed to be cleaned off before wetting but has now dried hard.
What's the best way to remove this stuff from the block paving?
Thanks
