Cleaning cobble-lock

    Is it ok to use a power washer on cobble-lock ... some people say it may dislodge sand etc.

    The power washer I have cost 180 in Atlantic - so it is not extremely high powered - and the bricks are very close together - you can hardly see any sand in most cases. Any advice? Thanks.

    If there is loose sand there then a powerwasher will wash it out.
    Try and adjust the jet to a wider spray and hold it as far as you can from the surface.
    Also, work diagonally (like grouting tiles), it might help to not remove the sand.

    If you use a fine spray on a power washer or just a garden hose, get a bag of kiln dried sand to sweep back into the joints as soon as it is dry. Will save you a lot of hastle down the road.

    Thanks - I will get some of that sand, presumably from builders providers.

    Cobbles are difficult to sand when wet though. You're better off leaving it a day or two.

    Sorry for resurrecting an old thread. I’ve a good area to clean and am wondering if I’d do harm with my washer. It’s a proper one that I use for cattle sheds. 13 hp and hawk pump. Would I be better buying a circle sweep attachment to ensure damage isn’t being done? Thanks

    Shouldn't do any damage. For cobble lock znd powerful washers wear goggles. Lots of stuff flies back at your face. As mentioned sand will be lost. Replace when its bone dry.

    Would I need the round attachment? It’s a big area. Thanks
