Repair and Protection of Fair-Faced Concrete and Fibre-Reinforced Concrete
Protection of old and new fair-faced concrete, as well as surface protection and improvements, are other topics that LETOON MİMARLIK specializes in. The goal of these applications, also known as Concrete Cosmetics, is to perform the required protection and repair without harming the projected character of the concrete and its texture. The results after applications are quite successful and satisfying. Shortly, functions can be summarized as below:
- Matt appearance as concrete
- Match with concrete colour
- Complete texture adherence
- Subtilization to requested ratio with KEIM Concretal-Fixativ or/and Concretal-Base
- Definitely UV resistant
- Durability due to silicate silification
- Non-flammability
Our firm is the Turkey Representation of two firms in this sector:
- KEIM Mineral Based Potassium Sol-Silicate Paints
- EVONIK – PROTECTOSIL Silane Based Construction Protection Technologies
KEIM Mineral Based Potassium Sol-Silicate Paints
KEIM Mineral Based Potassium Sol-Silicate Paints, represented by our firm, have been commonly used in North America since 1878. Silicate paints penetrate the surface where applied and create a chemical interaction, resulting in a very good combination of inorganic colour pigments of sodium silicate and mineral-based saturating. It becomes part of the surface, not just a coat that covers it.
The surface maintains a mineral matt appearance just as natural concrete. Wooden mould trails are preserved, and at the same time, the coating forms a very strong bond with the surface due to the silification process. Thus, the surface is protected against weathering. According to the architectural design, coats can be more or less transparent and have a colourful appearance related to the dilution rate of the original concrete material. While one of the important parts of the application is to balance colour differences with “Concrete Grey”, most architects prefer to use colourful or concrete grey silicate mineral paints for the maintenance of concrete.
These are not the only purposes of using KEIM Potassium Silicate Paints. Besides, they are chosen for the reasons below:
- Its binder, Sodium Silicate, is very durable against UV.
- Silicate paints have high water vapor transmission.
- Thanks to low Sd values (<0.02 m), concrete can dry again very rapidly.
- Pigments used in silicate technologies are non-mineral pigments and are not affected by UV radiation and adverse weather conditions. Because of this property, swelling or spalling is not observed on silicate mineral paint-applied concrete surfaces.
- Due to Pure mineral pigments (Fb code B1), absolute colourfastness is provided.
- Due to the existence of pure mineral pigments and the surface drying fastly, moss and mold are not observed.
- Thanks to non-thermoplastic and anti-static adherence, a very low level of dirt accumulation is provided.
- Silicate mineral coatings have an excellent environmental profile; they are non-flammable and toxic odor-free.
The original concrete appearance is protected completely due to the mineral matt surface. With its 130 years of experience, KEIM also has plenty of products and solutions related to concrete surface protection and fair-faced concrete applications.
EVONIK – PROTECTOSIL Silane Based Construction Protection Technologies
EVONIK, operating researches, developments, and production of silane for 60 years, provides suitable solutions for all requirements in the construction protection sector with the Protectosil product group.
