Hi there
I've just bought a Pressure Washer for car cleaning and also to clea the patio which is in a sorry state. I plugged it in for the firs time yesterday and had a go at a couple of slabs and the result wa amazing but......whilst getting rid of the moss and weeds that hav grown in the gaps between slabs, all of the gaps inbetween are now ver "empty" - there's no mortar inbetween them and it looks a bit odd. Should I be replacing the mortar - I really dont know what it actuall is - once the slabs have been blasted clean? And if so, what do use?? Grateful for good advice as usual
Ale
