It's virtually fool proof in use – simply wet the paving thoroughly, pour it on, sweep it and wash it in, whilst cleaning the excess compound off the surface as you go. Once done you can "strike" the joints with a pointing iron by simply running it quickly along the joints using minimal pressure. Compression of the joints has already happened via the washing in process, so there’s no need to apply much pressure at all. easy fix easyfix
Speed of application is not the only benefit gained by washing the compound in – it means that every nook and cranny is filled quickly and easily, creating a very strong joint and an effective bond between the compound, paving and paving base material. This results in a durable joint without voids; reducing the risk of damage by freezing weather. It also minimises the chances of insect penetration and weeds are much less likely to gain a foothold too – both of which are very damaging.
