Sports parquet is subject to high surface load as the location of various training sessions such as gymnastics, basketball, volleyball and handball, and sometimes also dancing lessons and competitions, which is why the quality of surface protection must be very high.

Parquet lacquers for sports halls must comply with DIN 18032, EN 14904 and EN 13036-4 standards, which define the capability of sports floors to facilitate rotational movement of athletes while also preventing uncontrolled skidding. To fully meet all the requirements that ensure the safety of athletes, sports hall floors must fulfil a number of requirements including those relating to prescribed floor elasticity, proper load distribution, resistance to wear and appropriate slip performance. The two most important characteristics that can be influenced with parquet protection systems for sports halls are resistance to wear and slip performance.

Chromoden Systems of lacquers for sports halls have been tested by several authorised laboratories such as the Slovenian Building and Civil Engineering Institute (ZAG Ljubljana) using the method SIST EN 13036-4:2004 which fully meets the criteria of SIST EN 14904:2006, and the LDG Laboratory at the Faculty of Forestry in Zagreb.

It should be noted that measurements are carried out on dry and wet surfaces.

The established practice all over Europe is the use of various testing methods for measuring surface friction/floor slipping in sports halls. If testing is carried out according to EN 13036-4 (RRL pendulum method) or W1 217061 (Stittgart method) or EN 14837 (Le Roux method), skid resistance requirements must meet the following criteria:

There are two basic Chromoden Systems, water-based and solvent-based, both consisting of a primer and two top coatings. These can also be combined, which means that the first and/or second coat should be a solvent-based Chromoden System product (2K Primer LZP or Chromoden Transparent or Chromoden 2K Oil) or another solvent-based product that is part of our system, such as BORI Thin-Layer Woodstain for painting penalty areas or Heliodur 2K PU paints.

When lacquering parquet in sports halls it is not only important to select good lacquer but also to pay special attention to the following considerations:

• lacquering new parquet is different from renovating existing parquet;
• in the case of new parquet it is enough to select our recommended system;
• in the case of renovating existing parquet you should consult our Development & Application Service;
• it is essential that the inter-layer distance between the primer, the line lacquer and the top coat of lacquer is as small as possible (as per instructions);
• for better adhesion, each layer of lacquer and enamel should be sanded.

The basic properties of CHROMODEN Systems for sports halls:

• slip resistance;
• exceptional durability and resistance to wear;
• distinguished by high film hardness and fullness;
• easy to maintain and resistant to the effects of mild chemicals;
• gloss level 30-40% (matt).

When applying the system it is vital to follow a few practical tips and recommendations:

• mandatory use of slowing agents (Chromoden MP slowing agent or chromoden Aqua slowing agent);
• recommended conditions:
  optimum working conditions are air temperatures between 18–22°C and a relative humidity of 40-75%. The temperature of the room and the lacquer temperature should not be lower than 13°C, and the parquet temperature should no be below 12°C.
  In summer conditions with high air temperatures, lacquering should be carried out in the early morning hours;
• the application interval between the primer coat and the top coat should not be longer than 3 days to avoid disrupted inter-layer adhesion, which may result in peeling, as sports halls are exposed to a high load on a daily basis.
  The interval between other layers should not exceed 48 hours;
• inter-layer sanding is essential to avoid peeling, in particular because the surfaces of sports halls are subject to exceptionally high load and the constant impacts cause peeling if the substrate is not properly prepared;
• it is vital to minimize draft – while painting close all doors and windows and turn off any AC devices;
• filling the gaps and cracks between parquet blocks is not recommended, because the putty will fall out of the grouts when the parquet is in use;
• don't combine nitro- or alkyd-based paints or products made by other producers;
• the prescribed method of application should not be paused;
• lacquering requires a large and well-coordinated team of floor-layers;
• the surface is walkable after a minimum of 48 hours;
• the lacquer mixture for coating the entire surface should be mixed all at once in a single container;
• before use, the lacquer should be brought to the temperature of the room;
• it is crucial to monitor all the prescribed conditions throughout application.
