Correct exposed concrete professionally, harmonize the color and preserve it as an authentic concrete surface.
Concrete surface refinement
The quality of the exposed concrete may not always meet your expectations. Defects such as color inconsistencies, gravel pockets, flaking or an irregular formwork appearance do not represent an obstacle for our experts. Binding points can be closed and made invisible through color retouching.
Incorrectly planned recesses for sockets or similar are quickly remedied by our experienced team. The appearance of the exposed concrete surface is changed using fillings, retouching and other measures until the surface meets your requirements.
At a glance
Concrete cosmetics correct visual defects in exposed concrete without losing the character of the material. It is suitable if concrete surfaces are stained, cloudy, dirty or appear inconsistent due to formwork, broken areas and repairs.
Concrete cosmetics are relevant for architects, builders, general contractors, administrations and public clients who want visible concrete surfaces to be finished in a clean design and technical manner.
Different formlining, moisture, post-treatment or repair points change the appearance of the concrete.
BKOS adapts the surface to the specific object and selects correction techniques, pigmentation and protection to suit the exposed concrete requirements.The surface appears calmer, more uniform and remains recognizable as concrete.
Local visual disturbances occur when concreting, removing formwork or after construction work.
Defects are prepared, filled, structurally adjusted and color integrated.Connection areas are less noticeable and the quality of the exposed concrete increases.

What is crucial is realistic patterns, clean surface preparation, products that are suitable for the material and a result that does not look like paint on concrete. Not every material defect can be made invisible; BKOS states limits before execution.
BKOS works throughout Switzerland for private, commercial and public construction projects. The deployment planning depends on the object, surface, access and appointment window.

Typical applications include color differences, clouds, gravel pockets, pores, binding points, small breakouts and repairs that remain visible. Before execution, BKOS checks whether a cosmetic correction is sufficient or whether a technical renovation is necessary first.
A professional correction can significantly calm defects and integrate them into the existing concrete look. Complete invisibility cannot be reliably guaranteed due to color tone, pore structure, light and aging; That's why BKOS works with sample areas and realistic target images.
No. Concrete cosmetics are suitable for new and existing exposed concrete surfaces. For existing areas, contamination, previous coatings, moisture and aging must be assessed in advance.
The duration depends on the area, damage pattern, accessibility, drying times and the desired visual quality. Small local corrections are often possible at short notice; Larger areas are planned in sections after sampling.
The decisive factors are the area, number and type of defects, scaffolding or access, desired surface quality and necessary patterns. A reliable offer is therefore only possible after pictures, plans or a property assessment.
