A weak cementitious joint-filler can also be used, such as hydraulic lime.The floor is then sprinkled with linseed oil, and this treatment is repeated twice at intervals of one week. After each treatment surplus oil must be wiped of. The linseed oil binds the sand in the joints and makes the brick surface easy to clean. It is also possible to treatjust the joints with linseed oil, and treat the bricks with a soft soap.

Re-usable brick flooring can be used in most houses, and is especially appropriate where there is underfloor heating so that this is easily accessible for repair or modification.
