Frequently asked questions
Is Cerámica Mayor ceramics anti-slip? Under which classification?
Yes. The manufacturer classifies its anti-slip porcelain stoneware as C3 under standards UNE-ENV 12633 and DIN 51097. The first determines the coefficient of friction and therefore the slip resistance of ceramic surfaces, and the second assesses slip resistance in wet areas such as pools, showers or bathrooms.
Where can I use the C3 anti-slip finish?
Cerámica Mayor indicates the C3 finish for commercial spaces (restaurants, shops, shopping centres and healthcare spaces), industrial facilities where there may be liquids and oils, pools and wet areas, and airports and transport stations. The manufacturer itself points out that the C3 finish is available both as a tile and as special pieces: steps, pool edges, drainage grates and cove pieces.
Can I deal with a pool edge or a step by laying flat tiles?
The manufacturer does not recommend it. Cerámica Mayor explains that it designs and makes each piece for a specific use (steps, pool edges, drainage grates) and states that laying flat tiles is not a good option for these situations. It also has a library of pieces and can make pieces to measure.
How are the steps and cove pieces laid?
According to the manufacturer's laying instructions, the substrate must be level, waterproofed and with adequate drainage or fall. The pieces are laid with flexible C-2 TE S2 tile adhesive applied as a double layer, bedded in with a rubber mallet and grouted with CG2 cementitious material.
Does it stand up to chlorine and pool water maintenance products?
Yes. Cerámica Mayor states that its ceramics are resistant to chemical products and that they do not stain or change because of the additives used to maintain pool water. It adds that maintenance is straightforward because the pieces are cleaned with water.
What formats does the 20 mm flooring come in and how is it installed?
The manufacturer offers the 20 mm (2 cm) flooring in two rectified formats: 60x120 cm and 90x90 cm, with a C3 outdoor finish. It sets it out for laying on grass (removing about 5 cm of soil and creating a gravel bed), on gravel, on sand, on levelling pedestals and also in traditional laying. Cerámica Mayor intends it for residential, commercial and public areas with heavy footfall.
