How To Apply

Application can be by a low-pressure sprayer (as could be used for weed-killer) or watering can, sponge, paint roller or poured on straight from the jerrycan. We tend to favour a decent covering as most effective and try to puddle the cleaner on the slabs when we use it. A power washer or garden hose is helpful and disperses the dirt better after cleaning, it can be surprising how much dirt is liberated to get rid off.

Agitate the solution with a stiff brush and leave for quarter of an hour before rinsing off with plenty of water.

Please see a video showing how to best apply and agitate the product for better results:
