Frequently asked Questions

Colour
Concrete Stock Bricks, Plaster Bricks and Base Clinkers are for plaster purposes only. No claims will be
accepted for variation in product colour.
Rock Face Bricks - Bricks may vary in colour tone and shade within the block, and from one production run to
the following. To prevent colour banding, bricks should be blended on site by taking small quantities of bricks
from as many different packs that are available, and stack these in a wheelbarrow for direct use by the
bricklayer.

Efflorescence
This is due to dissolved salts in the cement and aggregates migrating to the surface and
forming a white crystalline layer, which is soluble in dilute acid. Efflorescence is influenced by rain with
subsequent drying.
This may affect the colour of bricks and pavers, but can be removed by washing with diluted hydrochloric
acid. 1 Part acid mixed with 20 parts water. (Pool acid can be used if it is hydrochloric acid. )
Zenzele does not accept responsibility for the occurrence of efflorescence on its products, or treatment
thereof.

Dirty or Soiled Bricks and Pavers
Due to the nature of our industry and products, it is possible that products can get dirty occasionally.
Customers may find that the bottom layers of bricks in the packs are soiled due to dust or mud.
It is a generally accepted practice for contractors to clean brickwork or pavers thoroughly after placement.
This practice will rid the bricks of dirt and dust that has accumulated during storage, transportation and on
site. Claims for soiled products will therefore not be accepted.
