Surface preparation

Surfaces to be treated must be clean, dry and free of friable material, wire brushing or sweeping is usually sufficient. Watco Bio D degreaser can be used if there are spots of oil or grease.


Each bucket contains Concrex powder and bottles of hardener. Mix the two components with a trowel until you achieve a uniform grey colour, you can complete the mixing by using your gloved hands. For large quantities, it is advisable to use a mixer.


Apply the repair mortar to the surface to be repaired and smooth with a trowel. To prevent streaks, wipe the blade with a rag soaked in white spirit.
