Reagents for oxidising concrete surfaces - Oxicem® Concrete

Oxicem® Concrete is the line of colouring chemical reagents for staining and oxidising concrete surfaces as well as other cementitious and mineral surfaces. Products that offer the most unique decorative finishes for decorative paving and walls.

Available in 7 colours, they produce by chemical reaction a colouring on the substrate to be treated, automatically generating coloured mineral nanocrystals. Materials that are stable to light, which facilitates the use of our reagents both outdoors and indoors.

Chemical dyes that can be applied in all kinds of shapes and are perfect for transforming and oxidising old concrete surfaces. Polished concrete, precast concrete and stamped concrete coatings, but also microcement.

With Oxicem® Concrete it is very easy to renovate environments and surfaces worn by the passage of time. An original decorative finish that does not lose that natural vintage look so in demand today.

How to apply Oxicem® Concrete for oxidising concrete surfaces

Prior to the application of Oxicem® Concrete oxidising reagents for concrete surfaces, the substrate to be coated must be prepared. The substrate must be clean and dry. If it has been varnished or painted, the coating must be removed by sanding or stripping.

1. Protect the perimeter and areas where Oxicem® Concrete chemical stains are not to be applied. Especially if they are metal, wood, lacquered or glass areas.

2. Apply a coat of the desired colour of Oxicem® Concrete for rusting concrete surfaces. The product can be applied by brush, roller or spray.

3. Add a second coat, if desired, to finish decorating. In this case, a drying time of 8 to 12 hours between coats must be observed.

4. After each coat of Oxicem® Concrete for rusting concrete surfaces, the surface must be cleaned with water and allowed to dry.

5. We recommend protecting the new decorative coating with a water repellent, as this ensures greater protection against water and subsequent soiling. It can also be sealed with any of our TOPSEALER®, SEALCEM® WT or SEALCEM® DSV coatings.

Precautions for rusting concrete surfaces with Oxicem® Concrete

It is corrosive to skin and eyes and prolonged exposure may cause drying, cracking or discolouration of the skin.

Harmful by inhalation. Therefore, the use of a mask with chemical absorbent and good ventilation in the room is mandatory.

In addition, protective goggles to prevent splashes and rubber gloves must be worn.

Properties and uses of Oxicem® Concrete for oxidising concrete surfaces

One of the main peculiarities of these reagents for oxidising concrete surfaces is that their colouring is uneven and semi-coatable. This means that the final finish respects the textures of the substrate, thus maintaining its natural appearance.

Another factor to take into account is that the final results will depend on the type of concrete to be oxidised, the original colour of the coating as well as its age, porosity and the proportion of the mixture on which Oxicem® Concrete is to be applied.

Our chemical stains for oxidising concrete surfaces can be used without any problems outdoors. Among its most recommended uses and fields of application, we highlight the following: paving in hotels, corridors, shopping centres, parks, pedestrian areas, etc. Although it can also be used on vertical surfaces.

Chemical dyes in aqueous solution, so they are soluble in water, and offer evaporation drying. A system for high decoration that provides exclusive finishes and textures thanks to its range of colours, creating a contrast with the rest of the elements in the space.

Oxicem® Concrete colours for oxidising concrete surfaces

Amarillo, Bronce, Negro, Oliva, Pardo, Turquesa and Verde Océano are the seven colours available within the Oxicem® Concrete family. These colours offer very different finishes depending on the shade of the concrete coating to be oxidised and its sealing.

In this sense, if light-coloured concrete surfaces are to be oxidised, the final coating will have a very different appearance to one that is darker, although the colour of Oxicem® Concrete is the same. Similarly, the final texture changes completely after the use of Topsealer® WT One Coat sealer.

The colours shown for Oxicem Concrete® to achieve a rust effect on concrete are digital simulations. It is possible that the results of the samples do not match 100% when applying our chemical stains on a surface. For this reason, we advise you to consult the catalogues of real samples beforehand.

Below we show the different rust effects on concrete that can be achieved by using Oxicem® Concrete on light coloured coatings. The image on the left is of the unsealed coating, the image on the right is the texture resulting from protecting the coating with our water-based polyurethane varnish Topsealer® WT One Coat.

Rust effect on concrete with Oxicem® Concrete on dark coatings

As can be seen with the naked eye, the finishes of Oxicem® Concrete change considerably when applied to dark coatings. In the samples on the left, we can see the rust effect on concrete before sealing. On the right, the final finish after the use of Topsealer® WT One Coat varnish.
