Product is suitable for interior and exterior applications.
Product is effective in 1-5 hours depending on the condition of the substrate. Always perform a product test patch prior to full application to determine optimum dwell time.
When using chemical removal products, the first rule is not to remove them until they have been given time to work.
It is therefore recommended that a minimum dwell of 1 hour should be given. Rust Remover will turn a dark green colour when activated.
Rust Remover GEL (SPRAYABLE) will turn a dark green colour when activated.
Patch tests are very important and must be carried out prior to application.
It is important to obtain an even coverage either by spray, brush or trowel. A good build up of product is essential where 1 litre of product should cover 1m2 of surface.
Colour – Hazy /Transparent
pH - 2.0 to 3.0
SG - approx. 1.00
Gel Viscosity - 9000 to 18000cps Flash Point - > 100C
Heavy oils and residues should be cleaned prior to application of the product.
Heavily soiled surfaces we recommend power washing to remove loose material.
Protect areas sensitive to chemical and water exposure with masking or a polyethylene plastic.
Apply using an airless sprayer or HVLP equipment. Never use metal brushes.
Do not atomize.
Use equipment capable of 2000 psi. Rust Remover GEL may be applied by Brush, Trowel or Spray. It is important to use a soft medium and apply generously to ensure an even and adequate coverage.
Rust Remover GEL (SPRAYABLE) should be spread over the surface and allowed to thoroughly activate before removal.
A general rule is that when the entire surface has turned black or dark green the product has fully activated.
It is recommended that temperatures are above 5 to 10oC. The product works better at warmer temperatures. Surfaces should be dry. Good ventilation should be provided in confined areas.
Rust Remover PASTE (THICK) Rust Remover GEL (SPRAYABLE) can be left on the substrate indefinitely and will not attack the healthy metal.
If left, the Rust Remover PASTE (THICK) and Rust Remover GEL (Sprayable) forms a “crust” on the surface, acting as a protective barrier for carbon steel items, preventing rust from occurring during transport or storage.
When item is ready for use, pressure washing will remove hardened “crust” and substrate is clean, free of mill scale and ready for use.
If a pressure washer is not available, Rust Remover PASTE (THICK) and Rust Remover GEL (SPRAYABLE) can be applied to the surface to “reactivate” itself so that it can be removed by washing.
