Good evening peeps,
I do quite a lot of block paving P/Washing and normally apply a 5% hypo mix down prior to washing.
However i've been asked to clean a very dirty Indian Sandstone patio so i just wanted to know if its safe to use hypo on that too.
If it is, then what % mix would you use, dwell time etc.
Any advise would be much appreciated.
