Step 1, Oiling the moulds- all surfaces exposed to cement

A,vibrate by hand if no vibrating table available
B,when by hand first fill the moulds then tap with rubber mallet
C, do not top up the mould with mixture after casting, settlement of the mix is essential :1- 3 mm.
Step 3, Curing
Moulds need to be stored on a level surface for 48 hours. The moulds must not be moved during this time as microscopic cracks will form decreasing the strength of the block.
Production must be done under shelter.
Step 4, releasing the moulds
Do not veer from the unzipping method shown in these pictures, as you may damage your moulds or block.
Do not hit directly onto strips when removing.
First use a small washer to unzip, then use bigger washer provided and roll down both sides.
