This image shows a brick range fire place in Tyrella House.

This was created from reclaimed bricks that had previously been bed in lime mortar. This allowed the bricks to be cleaned and re-used.

The bricks were then bed once more in 3/1 lime putty mortar. The lime mortar and soft clay bricks can be powdery. This is a particular problem as it can get into the food and will also allow cooking oils and fats to be absorbed into the wall.

Biofa Stabilising Primer offered the solution. It was diluted 50% with water and two applications made.

The result is a no powdery, breathable, matt and wipeable surface.
