  • The surface of rubber mats should be laid on a concrete foundation (on a self-leveling screed). Floors (panels, carpet) are also acceptable, provided the surface is even, hard and forms a uniform layer
  • The substrate should be cleaned before laying (rubbish, crushed concrete, etc. must absolutely be removed completely before installing the panels)
  • The mats should not be laid at temperatures above 25°C and below 5°C
  • The mats have two sides – the top one (bevelled) and the bottom one (smooth)
  • The individual mats are connected to each other in an adjacent or interleaved arrangement
  • Start laying the mats from the wall itself and work towards the opposite side. The spreading of the first and second rows is very important to ensure accuracy and no gaps in subsequent rows of the installation
  • Due to the firm fit of the individual edges, do not be discouraged by initial unevenness after laying – after a short time the whole structure will even out (granules / rubber is a material that adapts and changes its properties under the influence of temperature)
  • Any cutting (at walls, pillars) is always done by the customer himself
  • To cut the mats, use a sharp knife and make 2-3 deep cuts (the strip along which you cut may be helpful). In order to facilitate this process, a second strip can be placed under the cut mat (after the first cut) to bulge the mat and facilitate cutting
