Blackfriar Professional Concrete Repair Mortar

Blackfriar Concrete Repair Mortar is a two-pack, high performance, quick hardening epoxy concrete repair mortar for damaged and eroded concrete, masonry and brick surfaces within heavy traffic areas. It forms a strong and permanent bond to concrete surfaces.

Preparation

Ensure the surface to be painted is sound, clean, dry and free from grease or any substance liable to give adhesion problems. Wire brushing or sweeping is generally sufficient. If the surface is damp it can be primed with Blackfriar Professional Damp Proof Primer. A primer is generally not needed if patch or crack repairing but if Blackfriar Professional Concrete Repair Mortar is to be applied in thin section or to smooth or non porous surfaces use Blackfriar Professional Oil Tolerant Primer.

Application

The base and activator components each contain resin damped aggregates. Discharge the entire contents of each component onto a mixing board, then mix together using a trowel until a uniform colour is produced. Using a trowel or a plaster’s float apply the product firmly against the prepared surface. To prevent drag on the trowel and to produce a smooth finish, lightly wipe the tool with a rag moistened in white spirits.

Blackfriar Professional Concrete Repair Mortar is normally applied to a thickness of 5 to 50mm on horizontal surfaces (up to 10mm on vertical) and can be feather edged to produce a neat finish as long as the main repair is at least 5mm thick. For repairs deeper than 50mm apply multiple layers allowing 6-8 hours @20°C between layers. Blackfriar Professional Concrete Repair Mortar cures at temperatures above 10°C. Do not steam clean or subject the finished repair to temperatures above 50°C. In some circumstances discolouration may occur on some vinyls when laid over repairs. Use product within 30 minutes of mixing @20°C.

Drying Time

Light traffic accepted after 6hrs @20°C. Heavy traffic accepted after 12hrs @20°C. Allow to dry for a minimum of 6-8hrs @20°C between coats. Blackfriar Professional Concrete Repair Mortar cures at temperatures
above 10°C.

Clean Up

Remove as much product from application equipment as possible before cleaning with White Spirits before mortar cures. Do not empty into drains or watercourses. Some local authorities have special facilities for the disposal of waste coatings.
