Best power washer for a Tarmac drive?

ali-t

The sprucing up the house and garden season has hit and I'm looking to get the green layer off the Tarmac in the back garden.

I think it is a mixture of stray grass clippings, dog pee and leaf residue from autumn. There are a few weeds creeping through the tar and I don't want to damage it further. I'm looking for recommendations for a suitable power washer.

I saw a cheap one in Argos that had excellent reviews and a small archer one but it is quite a large area and it was reccomended for smaller areas. I have Tarmac bits at front and back of house that would fit approx 20 cars on in total.

We have a tarmac drive that gets mossy but having tried our jet wash on it decided it was going to break up the surface and cause damage . I now put a moss killer down its not perfect but does a good enough job.

I have a tarmac drive that accumulates moss but I wouldn't use a power washer as I suspect it would start to break up.

The trouble with a good moss killer is the expense.

If you don't hold the power washer for too long in any one place then your tarmac shouldn't break up. We've been using pressure washers around the house for donkeys years without adverse effects. Proffessional power washers are deisel or petrol powered and are very powerful. The one which we've got is quite a powerful electric one and is an EDGE Leopard make. https://www.google.co.uk/search?q=edge+leopard+pressure+washer&newwindow=1&hl=en-GB&source=lnms&tbm=isch&sa=X&ei=Pl5KU8XXCsPg7QaF_oHIAw&ved=0CAkQ_AUoAg&biw=1024&bih=629

I don't think you need one as powerful as this but it works really well.

I can fill a wheelbarrow with loose tarmac if I even so much as sweep the drive with a broom.

Best & cheapest moss killer you will find are Soda Crystals....about 75p a kilo in all the major supermarkets.
Sprinkle it on liberally then dampen it.........moss him dead in a few days !!

You can probanly get salt even cheaper than Soda Crystals which is a good homemade weedkiller.

I know somebody who puts a dash o hypochorite into the water. But don't spray on other plants which you don't want killing. And don't use on cars etc either.

I know a few of them but I'm not sure I could get one in my watering can.

I meant 'hypochlorite'. :-)
