This table is only a guide and is prepared from the mixes we use. You may prefer to build retaining walls, for example, out of sharp sand and cement alone. We have added lime to allow the walls to breathe a little. A colouring can be added to the mortar to match any existing colours and this should be added to the cement before it is mixed with sand and water. The correct procedure for mixing mortar is shown below.
See also matching sand and cement mortar for how to match new pointing etc to old.
Our project on repointing brickwork may also help.

Mixing the Aggregate
Having mixed and aggregates (soft and sharp sand + lime) together, form a circle with the mixture and hollow out the centre. Tip or shovel in the required amount of cement. Mix together shoveling in towards the centre. When the complete mix is one uniform colour, hollow out the centre once again. Tip water into the centre. Start with ½ a bucket and (after the first mix you will learn how much water your mix will take, until then you may have to keep adding it in small amounts. It is much better to have too little and add some more, than to have too much. Mix everything into the middle once again and keep "turning over" until the whole mix is an even colour and consistency. All tools required to mix mortar, lay patios and build walls can be bought from our tool store below.
