How to mix mortar by hand, step by step: the tools, the right ratio, mixing order, adding water in stages, slaking and retempering, plus the mistakes to avoid.
The honest mortar water ratio: realistic starting amounts per bag, why damp sand and the weather move the number, and how to add water in safe, small stages.
Simple field tests for mortar consistency you can run with a trowel: the ridge test, the cling test, board slump, plus a wet-versus-dry symptom and fix table.
How long mortar lasts once mixed: the realistic 2 to 2.5 hour window, how weather changes it, when to retemper, when to bin a batch, and how to size batches.
Mortar mixer vs hand mixing compared: batch size, time, consistency, cost and cleanup, the job size that justifies a mixer, and the correct mixer loading order.
How to colour mortar so every joint matches. Coloured mortar comes down to batch discipline: iron oxide pigment dosage, test panels and matching old mortar.
