Ceramic Pro TAG is a progressive purification system based on photocatalytic effect designed to kill pathogens such as bacteria, microbes and viruses, which are a common cause of diseases, foul odors and mold. Applied on water-absorbing surfaces and exposed to a source of UV-rays such as sunlight, Ceramic Pro TAG decomposes 99.9% of pathogens present in the area. Common sterilizing products can kill the majority of bacteria and microbes, however, right after sterilization the pathogens resume reproduction and soon enough their number is back to where it was and continues to grow. The purifying effect of Ceramic Pro TAG on the other hand is long-lasting and will keep working for up to 6 months. The photocatalytic effect is similar to electrolysis. It breaks down the molecules of water into hydrogen and hydroxide, destroying membranes of bacteria and microbes and structural elements of viruses causing them to decompose or loose structural and functional integrity. Ceramic Pro TAG is completely safe and non-toxic for humans and pets. Coating cures in 1-2 hours after application at 25°C for dry surfaces and 3-5 days at 25°C for full more absorbent surfaces.
