This short video shows the mix, application and finishing of a modern reproduction flint wall using the Point Master tool with cement mortar.

It clearly indicates how easy the Point Master makes this previously difficult job. The most common alternative technique is to throw the mortar onto the wall with a trowel or hawk.

It is important to evaluate what the existing mortar is made from before attempting a repair and to ensure that similar materials are used. Doing this will ensure the aestetic, performance and durability of your repair.

Results are achieved faster and much more accurately than by traditional methods, where the mortar would have to be "thrown" into the joint manually from a trowel.

Because the Point Master is designed to ensure a complete fill of the mortar cavity "from the back", the mortar recess is always completely filled. This ensures the best repair in the shortest time.

When repairing or re pointing deep joints or stonework, always remember to remove all the loose and powdery mortar back as far as safely possible, then dampen the cavity and existing mortar before you start, to ensure the best adhesion.

How we made the mortar in the stonework video

As this wall is a modern reproduction, the use of 4:1 cement mortar is used.

Mortar is mixed starting from the dry parts and a good quality liquid plasticiser is added at the start of the mixing process. This liquid plasticiser is added directly to the mix and NOT into the water.

Water is then added gradually between stages of vigorous mixing.

Other additives and pigments are also compatible with the Point Master. Here we also add a weatherproofer additive.
