Pointing Mix Instructions

see the bottom of the page for a download / printable version of these instructions

Lay the stones with an ordinary mortar and leave the joints raked out to a depth of approx
10mm – 15mm
For the pointing mix:
• Mix pointing material supplied with white or grey cement* (see chart below) at 5:1 ratio (5
parts pointing material to 1 part cement)
• Mix approximately 1 part waterproof PVA to 5 parts water and use this to wet the pointing
material
• Wet the mixture so it only just holds together when compressed in your hand. Do not add
too much water as this will result in the mixture looking a much lighter colour than the stone.
- a normal bricklaying mortar is far too wet
• When pointing, use a small tool (small enough to fit into the joint) and pack the mix into
the joints tightly. Trowel smooth and leave to dry. Shade from strong sunlight and rain
initially.
