DIY Ways to Clean Sandstone Pavers and Walls

For all of its attributes, appearance being the most pleasing, sandstone is very porous so it accumulates difficult to remove mould, fungi and algae. Once they inhabit and begin to become absorbed beneath the surface of the sandstone, all three can be very tricky to eliminate. 

Obviously the best solution is to contact a service that offers professional sandstone cleaning in Sydney however, if you want to make it a DIY job and you can think you can do it effectively, then here are a few tips to help you along the way. 

The best sandstone cleaner and the best way to attack mould on sandstone walls is a chlorine bleach. Mix a cup of bleach water with about 3.5 litres of water and put it into a spray bottle. Concentrate the spray and then leave it for 10 or 15 minutes. Repeat the process before scrubbing it away with a scrubbing brush.

An ant-microbial spray will stop the mould from growing. The microbial forms a coating around the mould to both prevent it’s growth and to stop it accumulating anything that may initiate more mould growth. Instead of scrubbing, wipe away the spray away with an old rag. It is the best and safest way to clean sandstone pavers. It’s easy to walk the spores inside so removing the risk underfoot is important.

If you are removing mould while using chemicals, makes sure you wear rubber gloves, goggles and a mask. Also, make sure you dampen the sandstone before you attempt to clean or scrub it. You don’t want to spread mould spores inside your home or to another, less obvious, part of your home.

A sandstone sealant will prevent the absorption of moisture and the growth of mould algae and fungi. It is best to stay on top of their growth because they do have a tendency to grow quickly and if you are not careful then you could have a very big job on your hands.
