Resurfacing of Sports Surfaces

Resurfacing guarantees quality and cost saving

Resurfacing of sports surfaces is becoming more and more important. From both an economic and environmental point of view resurfacing is often the best option to maintain an existing sports facility. For your resurfacing project you can rely on CONICA's experience, technical support and the outstanding quality of CONIPUR products and systems.

1. Existing sports surface

Four important steps have to be considered for resurfacing:

1. Evaluation phase Check the existing sports surface for cracks and open joints (prefabricated sheets), excessive wear areas, delamination, low areas, bubbles, local defects and material decomposition. Adhesion tests must be carried out in order to find the correct primer and/or surface preparation. Force reduction tests indicate what type and quantity of CONIPUR materials are necessary in order to meet specific regulations e.g. IAAF. A careful analysis will show whether resurfacing is the correct option economically and technically. 2. Repairing area identified in 1 above Where necessary, the surface in the offending areas must be made level or completely removed and replaced with suitable material with similar physical properties to the existing surface. 3. Washing and/or grinding The whole surface to be resurfaced must be thoroughly cleaned, usually by high pressure washing (outdoor) or with alkaline cleaning agents (indoor). In some cases the top of the surface must be ground off before cleaning

Indoor sports surfaces

CONICA can turn any type of existing sports hall floor into a new looking, attractive and highly functional surface. We can refurbish, change colour, resurface or re-seal surfaces economically. Our specially designed indoor sealing products prevent excessive light reflection, give the required friction properties, guarantee colour stability and are very easy to maintain. CONICA also offers the possibility of resurfacing any type of existing sports hall coating (including non-PUR surfaces).

For your resurfacing project why not make the most of our experience and technical facilities? We guarantee outstanding quality at a truly competitive price/performance ratio!
