We test the resistance of surfaces to the effects of various liquids

The resistance of floor surfaces to various liquids is important to customers. In order to be sure of the chemical resistance of the surfaces of the manufactured products, we regularly perform surface resistance tests in accordance with EN 13442. The test method is relatively simple. For 24 hours, the surface is moistened with various liquids - water, coffee, acetone, ethanol, red wine, ink and other solutions. The sequins are then rated for surface damage on a scale of 1 to 5.

The test results show that the hard wax industrially treated surface with 30g/m² (1st row from the top in "clear white" shade and 5th row in "clear") protects very well against all liquids except ammonia. It can be seen that ammonia has damaged the wood even under water-based varnish (row 7 from the top), for which we expected better results. Increasing the application of hard wax to 140g/m² (2nd row from the top) gives the best results. Here, however, the surface has completely lost its natural appearance and is no longer different from a varnished floor.

Floors lubricated with natural oil (row 3) are the most sensitive. The following is a comparison (two rows - hard wax with and without deep structuring).

Oils with a higher amount of resin can be used (row 6). Here the results are good, however the tone of the wood is significantly yellowed compared to the samples treated with hard wax. The bottom last row shows for reference what effect the liquids have had on the untreated wood.
