Charles de Gaulle International Airport is the second largest airport in Europe after London Heathrow. It is located just outside Paris and handles over 50 million passengers every year. For this reason it can be difficult to find the time for maintenance and repairs.
"The airports floors have to withstand constant heavy traffic from passengers, staff and maintenance workers. It was therefore important that their repair and paint products were quick to apply, cure and hard wearing."
The work that needed to be carried out was at the entrance to Terminal 3 which is the main public transport hub for Charles de Gaulle. For this reason the work needed to be carried out and finished between the hours of 9.30pm and 6.30am. After this time heavy traffic would resume.
The first job was to clean the concrete floor slabs with Watco Concroff to remove all surface contaminants including oil and fats. Watco Concroff contains no solvents or other chemicals that are dangerous for the environment and penetrates even the thickest deposits of grease.
The floor was then primed with Tack Coat, an epoxy resin adhesive primer which guarantees excellent grip on the key surface.
As Charles de Gaulle is subjected to such heavy constant traffic a standard mortar would not be sufficient to withstand this, for this reason they choose Watco Concrex®. As it is as strong as granite it could be smoothed to a thickness of only 3mm, making the surface both waterproof and slip resistant.
The Concrex® was subsequently painted with Safety Coat. Safety Coat is roller applied and contains fine, traction enhancing particles embedded in an epoxy resin coating so this coating was ideal for providing a non slip surface for added security.
