NCC Cement, Grout & Salts Residue Remover is the modern alternative to dangerous acid based paving cleaners it is the best formulation we have found and is specifically designed for effective and efficient cement, cement grout and efflorescent salts removal. This advanced cleaning solution can be used to help remove cement, cement grout and efflorescent salt residues on all types of unpolished natural stone and porcelain tiled paving. This unique NCC formulation will also not cause ‘enhanced aggravated staining from any naturally occurring iron deposits, such as can commonly be found in light coloured sandstone and granite, especially with imported slabs.
Directions for use (Always Shake the Container Well Before Use)
As with all paving cleaning and surface treatments, we strongly recommend that you always test NCC Cement, Grout & Salts Residue Remover on an inconspicuous area prior to its general use.
Surface preparation:
Ensure that the surface to be treated is completely clean and free from any dirt and dust before application. Where necessary wash the areas first with NCC Grime Remover, rinse well with clean water and allow time to fully dry.
Cement, Grout & Salts Residue Removal:
1. For the removal of salts / efflorescence residues:
- Dilute NCC Cement, Grout & Salts Residue Remover 1:1 with clean cold water and apply liberally on the affected surfaces using a low-pressure spray unit or with a suitable brush.
- Allow the NCC Cement, Grout & Salts Residue Remover solution to work and react for around one hour at 20°C, do not allow to dry out. After one hour, or if it starts to dry out, re-apply and this time leave and allow to work for around half a day to a day, approximately 12 to 24 hours, then pressure hose / jet wash off with clean water.
- Allow to dry again and then give the surfaces a final treatment with a more dilute solution of NCC Cement, Grout & Salts Residue Remover, this time diluted 1 to 5 with clean water, leave for a further 12 to 24 hours and finally rinse thoroughly with clean water by appropriate hose / jet washing.
2. For the removal of cement and grout residues:
- Dilute NCC Cement, Grout & Salts Residue Remover 1:1 with cold clean water. Apply liberally over the affected surface and where necessary in heavier areas of staining / contamination, agitate with a scrubbing brush or so-called boat deck brush.
- Allow the solution to work and react for around 10-15 minutes at 20°C, do not allow to dry out by re-applying the solution as required whilst scrubbing the surface, then pressure hose / jet wash off with clean water.
- Repeat as necessary on any heavily stained areas, then allow to dry again and if required for overall cleaning and consistency, give the surfaces a final treatment with a more dilute solution of NCC Cement, Grout & Salts Residue Remover, this time diluted 1 to 5 with clean water, leave for an hour or so and finally rinse thoroughly with clean water by appropriate hose / jet washing.
