Repairing broken bricks is easy with Total Wall Care Brick Repair Mortar.

Whether damaged by impact, the elements, the removal of render, or by the use of the wrong type of mortar in the bed joint, damaged bricks are unsightly and can cause further issues with the building or structure through water ingress or failure. Repairing the damage with a cement or concrete mix not only looks unsightly but can cause  more severe damage in the future due to cracking caused by the repair material being harder than the original.

Fortunately an easy to use solution to repair broken brick is now available in the form of Total Wall Care Brick Repair Mortar.

Total Wall Care Brick Repair Mortar is available in a wide range of colours and sizes and, once mixed with water, is ready to use.

Here’s how:
