Washboy Hand Sponge
Often overlooked, the Washboy is an accessory that can help put the finishing touches to any joint grouting job.
The 23-litre bucket comes supplied with a sponge-faced hand trowel. It is very simple to use and as the video clip here shows an easy-to-clean double roller that sits on top of the bucket makes light work of squeezing out the dipped sponge.
Far more effective than a sponge on its own.
