A good bricklayer carefully plans their work prior to laying. This involves:
Bricks should be laid to a straight line which generally involves running a string line at both ends of the wall. Bricks should be buttered to form perpends (“perps”).
NZS4210:2001 sets out the following tolerances for brick veneers walls:
Bricks are natural products that are subject to colour variance between batches. ‘Blending’ is the process used to vary brick pallets as they are laid as a means of avoiding any unwanted patterns caused by a variance.
Master Brick & Blocklayers recommends that bricklayers select bricks and blend vertically from at least three pallets in order to achieve an adequate colour mix.
A bricklayer should also regularly check the veneer while laying from a viewing distance of 6.1m for obvious pockets of colour forming that may be unacceptable.
