STONESHIELD GROUT LIFT is an inhibited acid based cleaner for the removal of cement and grout residues from natural stone, slate, terracotta, bricks, porcelain, glazed and unglazed ceramics.
· An inhibited acid prevents attack or tarnish to metal surfaces.
· Contains detergents to remove oils and grease.
Dilutions:
For light cleaning (cleaning of unhardened grout haze), dilute one part STONESHIELD GROUT- LIFT to 30 parts water. Coverage approx. 60 m2 per litre. For medium cleaning, dilute one part STONESHIELD GROUT-LIFT to 15 parts water. Coverage approx. 30 m2 per litre. For heavy cleaning (cleaning of hardened grout), dilute one part STONESHIELD GROUT-LIFT to 5 parts water. Coverage approx. 10 m2 per litre.
Method of application:
Always test on a small area first, to ensure suitability and desired result. On glazed and non-porous surfaces, do not pre-dampen. On porous surfaces always pre-dampen the surface to prevent the acid from being absorbed too rapidly. Remove excess water prior to application of STONESHIELD GROUT-LIFT. For floors: apply diluted STONESHIELD GROUT-LIFT by mop, sponge or plastic watering can. For walls: apply diluted STONESHIELD GROUT-LIFT by spray, sponge or block brush. Allow 10 - 15 minutes for the product to work. Do not allow to dry out on the surface. Agitate with a nylon bristled brush or broom and then rinse well several times. If surface or tiles are to be sealed, ALWAYS neutralize the surface with STONESHIELD DEEP-CLEAN. Neutralizing helps prevent sealer failure.
Caution:
Not for use on marble, travertine, limestone, cement tiles and pavers or terrazzo. STONESHIELD GROUT-LIFT may cause certain natural products containing iron oxide to form rust. Always test first.
Precautions:
Ensure good ventilation and avoid breathing vapours. Avoid skin and eye contact. Wear goggles, gloves and suitable protective clothing when necessary. Keep out of reach of children and pets and store away from other chemicals. Do not allow contact with other sensitive surfaces.
