Cement Stains, Cement Gout Residues and Salts (Efflorescence) can be anything from unsightly and annoying, to a complete nightmare to remove from patios and other paved surfaces. Fortunately, NCC Cement, Grout & Salts Residue Remover is now available and the modern alternative to dangerous ‘Brick Acid’ cleaners. To be very clear - "BRICK ACID Cleaners of any type, SHOULD NEVER BE USED for cleaning any natural stone, concrete block or porcelain paved surfaces" - This is because the acid will attack many types of paving and grout, likely ruining the paving completely, and making the situation so much worse that taking it up and relaying with new slabs / pavers / tiles can be the only option!
NCC Cement, Grout & Salts Residue Remover is the best modern formulation that we have had specifically designed for effective and efficient cement, cement grout residues and efflorescent salts removal. This advanced cleaning solution can be used on all types of unpolished natural stone and porcelain tiled paving. This unique formulation will also not cause enhanced, or aggravated staining from any naturally occurring iron deposits, such as can commonly be found and especially in light coloured sandstone and granite paving slabs.
Limitations: Generally no chemical cleaners should be used on freshly grouted paved areas for at least 28 days, to allow the grout mortar to fully harden and cure. NOT SUITABLE FOR USE on any highly polished natural marble, travertine, or limestone surfaces.
Characteristics / Advantages:
- Supplied ready-to-use
- Acid-free formulation
- Water dispersed - Solvent free
- Fast-acting for quick results
- Removes ugly efflorescence salts
- Removes cement grout spillages
- Removes cement stains
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. Always mask and protect any adjacent areas and materials that are not being treated.
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 (www.nccstreets... ), rinse well with clean water and allow time to fully dry.
Application:
1. For the removal of efflorescence / lime / calcium salt residues:
- Dilute the 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 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 to remove any residual cement 'haze', 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 stains and/or cement 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 a 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 for any heavily stained areas.
You can also use a more dilute solution of NCC Cement, Grout & Salts Residue Remover for residual cement grout haze removal, this time diluted 1 to 5 with clean water.
Consumption / Coverage (per litre):
Approximately 5 - 25 m2 depending on the level and thickness of cement staining / cement grout residue / efflorescence salt deposits etc.
