Reagents for oxidizing concrete surfaces - Oxicem® Concrete

Oxicem® Concrete constitutes the line of coloring chemical reagents for tinting and oxidizing concrete surfaces as well as other cementitious and mineral surfaces. Products that offer the most unique decorative finishes for decorative pavements and for walls.

Available in 7 colors, they produce through a chemical reaction a coloration on the support to be treated, automatically generating colored mineral nanocrystals. Materials that are light stable, which facilitates the use of our reagents in the same way outdoors as indoors.

Chemical dyes that are applicable in all types of forms and are perfect for transforming and oxidizing old concrete surfaces. Coatings of polished concrete, precast concrete and imprinted concrete, but also of microcement.

With Oxicem® Concrete it's very easy to renovate environments and surfaces worn out over time. An original decorative finish that doesn't lose that naturalness of the vintage look so in demand today.

How to apply Oxicem® Concrete to oxidize concrete surfaces

Prior to the application of the reagents to oxidize Oxicem® Concrete surfaces, the support to be coated must be prepared. A substrate that must be clean and dry. If it were varnished or painted, it will be necessary to remove the coating by sanding or stripping.

1. Protect the perimeter and areas where the Oxicem® Concrete chemical dyes are not going to be applied. Especially if they are metallic, wooden, lacquered or glass areas.

2. Apply a coat of the desired color of Oxicem® Concrete to oxidize concrete surfaces. The product can be applied with a brush, roller or by spraying.

3. Add a second layer, if desired, to finish decorating. In this case, a drying time of between 8 and 12 hours must be respected between layers.

4.After each hand of Oxicem® Concrete to oxidize concrete surfaces, it will be essential to clean with clean water and neutralize with bicarbonate or ammonia until the residues are eliminated.

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

Special precautions for oxidizing concrete surfaces with Oxicem® Concrete

It is a corrosive product for the skin and eyes, so prolonged exposure can cause dryness, cracking or color changes in the skin.

It is harmful by inhalation. Therefore, it is mandatory to use a mask with chemical absorbent and there must be good ventilation in the space.

In addition, it is necessary to use protective glasses to prevent splashes and rubber gloves.

Properties and uses of Oxicem® Concrete for oxidizing concrete surfaces

One of the main peculiarities of these reagents for oxidizing concrete surfaces is that their coloration is uneven and semi-covering. This translates into the final finish respecting the textures of the support, thus maintaining the natural appearance of it.

Another factor to consider is that the final results will depend on the type of concrete to oxidize, the original color of the coating as well as its age, porosity and the proportion of the mix on which it is going to apply Oxicem® Concrete.

Our chemical dyes for oxidizing concrete surfaces can be used outdoors without problems. Among its most recommended uses and application fields, we highlight the following: pavements in hotels, corridors, shopping centers, parks, pedestrian areas, etc. Although it can also be used on vertical surfaces.

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

Oxicem® Concrete colors to oxidize concrete surfaces

Amarillo, Bronce, Negro, Oliva, Pardo, Turquesa y Verde Océano are the seven colors available within the Oxicem® Concrete family. Colors that offer very different finishes depending on the shade of the concrete coating you want to oxidize, as well as its sealing.

In this sense, if light-toned concrete surfaces are going to be oxidized, the final coating will have a very different appearance from one that is darker even though the color of Oxicem® Concrete is the same. Similarly, the final texture changes completely after the use of the Topsealer ® WT One Coat sealer.

The colors 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 dyes on a surface. Therefore, we advise consulting the catalogs of real samples beforehand.

Next, we show the different rust effects on concrete that can be achieved if Oxicem® Concrete is used in light-toned coatings. The image on the left is of the unsealed coating, the one on the right is the resulting texture of 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 at first glance, the finishes of Oxicem® Concrete change considerably when applying the product on dark coatings. In the samples on the left, we appreciate the rust effect on concrete before sealing. In those on the right, the final finish after the use of Topsealer ® WT One Coat varnish.
