Surface preparation

Clean the surface to make it free from dust, oil, loosely adhered particles, paint stains, efflorescence and other contaminations. The surface should be abraded or sand blasted to provide a rough surface to receive the repair mortar.
Cement Screeding, Rendering & Plastering

Seal the surface using 1 part Master Bond PVA to 3 parts of water. Allow it to dry, for bonding coat of 1 part Master Bond PVA diluted with 2 parts water (1:1 on low porous surfaces). Screed, plaster or render on the tacky bonding coat using normal techniques. Cure cementitious screeds and renders properly. Note: On totally non-absorbent surfaces such as polished granite, paintwork etc., the sealer coat may be omitted and the bonding coat should be 1 part of water to 2 parts Master Bond PVA.
Surface Sealer Coat

To seal highly porous and dusty, friable concrete, apply 2 coats of MASTER BOND PVA diluted at the rate of 1 part to 3 parts water and a final coat diluted 1 part MASTER BOND PVA to 2 parts water. Allow each coat to dry before proceeding. On less porous floors, the first coat may be omitted.
Key Coat/Tile Fixing

For porous and rough surfaces, bonding paving, terrazzo, quarry, slate and floor tiles, Prime the floor and back of the tiles as specified under priming. Mix 1 part Master Bond PVA with 3 part water and coat floor and tile backs. While still tacky
Concrete Repairing

Prepare and seal the surface as required, apply a priming coat of 1 part Master Bond PVA to 1 part water and allow to become tacky. Using the fine aggregate as in the concrete to be repaired, prepare a cement/sand mix in the proportions of 1:2 with 1 part Master Bond PVA to 3 part water.
