How do I apply mortars?

Mortar should generally be used within about 2 hours of mixing, otherwise it should be discarded. It should not be retempered. Hot weather may shorten the working life of the mortar due to water loss. The working life can be extended by covering the mortar. Bricks or blocks should be laid on freshly spread mortar. Once brick or block has been positioned, it should not be disturbed as this can readily break the bond.
