Bricks and blocks should be wet before you start the job. If too dry, the bricks will absorb the moisture from the mixture. This will weaken its strength.
Mix in a wheelbarrow, on a plastic sheet or on a pre-wet surface using clean, drinkable water wherever possible.
Empty contents of cement bag and mix thoroughly with sand and stone.
Gradually add water and mix to an even paste consistency. Use a maximum of 7 to 8 litres of water. Too much water will result in a weaker mortar.
Do not try to rework by mixing in additional water when semi-dry.
To take proper care of your project, prevent moisture by keeping it damp for 3 to 7 days. Gently spray with water and cover with plastic sheeting, hessian or damp sand.
