A Visual and Durable Upgrade for the Lobby Floor of an Office Building

This spring, a need for a new flooring solution was identified in the lobby of a property on Vuorikatu in Helsinki. The existing old concrete floor was cracked, difficult to clean, and no longer met modern aesthetic standards.
TKR Service served as a trainer in the coating work carried out by AIT Building Oy.
A Durable Three-Layer Flake Coating as the Solution
The project required the approximately 50-square-meter lobby area to be carefully protected during grinding and cleaning to prevent dust from spreading into the neighboring busy café.

The space was tightly sealed with plastic during the grinding phase, and plugs were placed in the intake and exhaust air ducts to prevent dust and other impurities from entering the ventilation system. After these measures, the concrete floor in the lobby was first ground smooth and thoroughly cleaned in preparation for the coating work.
After the preparatory work, the floor was smoothly coated with a three-layer TKR flake coating. In addition to the clear topcoat, shades of gray were chosen for the various layers, which over time would indicate wear and signal the need for maintenance.
An Easy-to-Clean and Waterproof Floor

Both the preparatory work and the actual floor coating had to be carried out at night to avoid foot traffic, ensuring the coating had time to dry undisturbed. The odorless and emission-free coating caused no inconvenience to people in nearby spaces.
The feedback was also very positive. Roll carts are transported daily across the floor to the café, and the surface has held up well under heavy use. With the new coating, the floor is waterproof and easy to keep clean for a long time.
