Requirements

For normal elevations an M6 mortar [1:1/2:41/2 cement:lime:sand] will be suitable when used at a consistency appropriate for the weight of the units. For stack bonding, stainless steel ladder type bed joint reinforcement should be used at each course.

Stack-bonded Fireborn®

  • Bed joint reinforcement is required.
  • Use every course for 215 mm high Fireborn.
  • Bed joint reinforcement is readily available from manufacturers such as Ancon, Bekaert and Brikmat.
  • As an alternative use Twin Block which can be laid in strecher bond and generally needs no reinforcement. This will save time and money on site.

Quality Control

  • Fireborn is made to uniquely tight tolerance which is ideal for stack bonding.
  • Fireborn is individually gauged and batched. There are three size bands ‘L’, ‘M’ and ‘H’ into which Fireborn is batched, thus providing the tightest tolerances in the market.
  • Each product is also colour checked with the Colourimeter, to ensure consistent and repeatable colour.

Blue Products

Natural blue Fireborn sometimes exhibits an oily coloured type of stain, generally referred to as ‘peacocking’. It is caused by light diffraction through a very thin surface layer of colloidal silica and it is noticeable because of the iridescent effect of the blue colour.
The staining is usually a result of:-

  • a) Saturation of brickwork prior to the mortar curing – giving a picture frame effect.
  • b) Fireborn coming into contact with copious amounts of water before being built in. The manufacturing process uses a layer of silica sand to separate the bricks during the firing process. Without this the bricks would fuse together in the kiln. The residue of silica on the bricks can turn blotchy when saturated.
  • c) Water run-off from cementitious areas.
  • d) A fine deposit of cement or lime transmitted to fine crazing lines by the moisture in the mortar at the time of laying.

All of the above are superficial; are not detrimental to the performance of Fireborn and all may be minimised by protection from saturation during construction. It is a normal phenomenon of natural blue fired clay products and it should be expected to happen.
Cleaning down with high pressure washers is not recommended!
