VARNISHING OF PARQUETS, LINES AND FIELDS IN SPORTS HALLS
Recreational rooms intended for practicing various sports must meet many requirements regarding safety, functionality, durability and ease of keeping them clean. The natural properties of wooden floors will be enhanced and preserved by a properly selected varnish system consisting of compatible products: varnish, primer and enamels for painting lines and fields marking the game. We advise you how to carry out work in the sports hall step by step using all products.
Consistent technology of the Domalux System
Products used in the sports hall must be resistant to abrasion, scratches and mechanical damage, and must be non-slip, and also meet criteria in the field of, for example, specular reflection. The comfort of using a sports floor is guaranteed by meeting the DIN 18032-2 or EN-PN 14-904 standards for sports floors. A product offered by the Domalux Professional brand, which is dedicated to modern wooden sports floors and meets the above-mentioned criteria, is the Domalux Professional Poliuretan Aqua 2S varnish (glossy, semi-matt version) intended for varnishing surfaces exposed to intensive use. It is a technical, high-quality product that allows you to use parquet in a safe way. So what should you pay attention to when applying this product? First of all, application in accordance with the manufacturer's recommendations, selection of the product adequate to the intended effect and combining it with an appropriate primer and compatible enamel for painting fields and lines demarcating the playing field.
System selection
The Domalux Professional paint system (water-based system) creates coherent technology and compatible products. It includes: Domalux Professional Polyurethane Aqua 2S varnish, AL cut-off primer. or Aqua Acrylic Primer and Dekoral Professional Acrylic Enamel (enamels are available in various colors in the Color PRO coloring system, including those recommended, consistent with the purpose of the sports hall, specified in the RAL pattern). The choice of underlay should depend on whether the painting work will be carried out on a new floor or on an already used floor (floor renovation).
Please remember that before using a two-component water-soluble polyurethane varnish, it must be mixed with a hardener.
Proper work flow
The work should start with a visual inspection, which will allow you to adjust the scope of work, products and plan the course of the renovation.
In the case of renovation, old protective coatings should be removed by grinding down to raw wood, which will result in the removal of all impurities, old coatings and preparation of the parquet for varnishing. Leveling, smoothing and finishing grinding are usually performed. Thanks to this, it is possible to obtain an even and uniform surface. After sanding work, the surface must be thoroughly cleaned of any dirt such as dust and dirt. Careful vacuuming, wiping the floor with a mop and antistatic cloths allows you to get rid of loose particles that could cause problems during painting works. The next step to ensure proper parquet renovation or protection of the new floor is to ensure optimal conditions for using varnishes (humidity between 40 - 65% and air temperature between 15 - 25°C).
The next stage of work is varnishing. In case of renovation, it is recommended to use Cut-Off Primer AL as the first coat. (apply once with a 100 ml/ m2 roller), which cuts off the remnants of pastes and waxes found in the gaps between the floor elements and the remnants of agents found in the wood (apply the primer with a roller). Moreover, the primer closes the pores of the wood and stabilizes its loose particles, ensures very good adhesion of topcoats and increases their efficiency. However, if we are protecting a new floor, the first coat is obtained with Aqua Acrylic Primer (apply once with a roller of 100 ml/m 2 ). After applying the primer, we start painting various types of playing fields in the color of the field (e.g. coffins on basketball courts, sponsor logos, etc.). To do this, apply two layers of Dekoral Professional Acrylic Enamel using a roller. After 24 hours After painting them, we start applying the Poliuretan Aqua 2S semi-gloss or gloss topcoat. Two layers of varnish should be applied (one application with a roller of 100-120 ml/ m2 ) approximately 8 hours apart. Then, it is recommended to sand between layers with sandpaper/mesh with a grit of 120-150 for the semi-matt version and 180-220 for the glossy version. After this procedure, the floor should be thoroughly cleaned. The next stage is to paint the pitch lines using previously used enamel (apply 2 layers). The work is finished with a single application of Poliuretan Aqua 2S varnish (volume 100-120 ml/m 2 ) to the entire surface.
Renovation of the parquet floor in this way allows you to obtain a surface suitable for safe practice of various sports disciplines.
What is important is that the painted surfaces can be gently used after 3 days, and full use can be introduced after 7 days, when the coatings gain full mechanical strength.
In addition, a varnished wooden floor requires proper care, i.e. regular maintenance and care. To ensure its shine, it should be cleaned with water with the addition of a dedicated agent, e.g. a care, maintenance or cleaning preparation for varnished floors. Thanks to this, we will achieve the final, intended effect.
The use of the system, i.e. high-quality products, as well as cleaning and care products, will allow you to use your parquet floor safely and to its full potential, even for several generations to come.
