Type 130 is a powdered iron oxide red pigment for colouring concrete, cement, mortar and other compatible mineral compounds.

It is suitable for decorative casting, art, design, crafts and construction projects. The pigment can be used to colour the entire mix, cast coloured figures, create marble and layered effects, apply thin coloured surface layers or prepare cement-based decorative paints. The manufacturer describes it as lightfast and suitable for cement-based systems.

Colour – Iron Oxide Red

Pigment designation: Iron Oxide Red Type 130.

The final red shade depends on:

• the colour of the cement or casting compound;
• pigment dosage;
• mix composition;
• water content;
• surface finish.

White or pale cement will generally produce a cleaner and brighter red, while grey cement may create a darker, earthier and more muted shade.

Dosage

The manufacturer's maximum recommended dosage for concrete and cement-based mortars is:

up to 5% of the cement weight in the mix.

For example:

• if 100 kg of concrete contains approximately 20 kg of cement;
• 5% of 20 kg = 1 kg of pigment;
• the maximum recommended dosage would therefore be approximately 1 kg per 100 kg of this concrete mix.

The 5% recommendation refers to the cement content, not the total weight of the concrete.

Use a lower dosage for softer or less saturated shades. For consistent results, test the colour in a small batch before preparing the full mix.

How to Use

The manufacturer recommends mixing the pigment into the dry compound before adding water.

1. Weigh the required amount of pigment.
2. Add it to the dry concrete, mortar or compatible mineral compound.
3. Mix thoroughly until the pigment is evenly distributed.
4. Add the specified amount of water.
5. Mix and cast as usual.

Suitable For

Type 130 can be used for:

• decorative concrete;
• casting concrete;
• cement-based mortars;
• compatible mineral plasters and grouts;
• coloured figures and decorative castings;
• marble and layered effects;
• thin coloured surface layers;
• cement-based decorative paints;
• modelling and casting projects.

The 5% dosage recommendation applies to cement-containing compounds. When using the pigment with gypsum or other non-cementitious materials, follow the instructions for the specific material and carry out a small test first.
