I have been using RedBag for a long time. I started working with apprehension, but the mixtures did not let me down, they are of very high quality. Excellent tile adhesive 113, better than Ceresit 117, the adhesive is elastic, very good adhesion. The first thing we tried was facade mixtures, it was scary, new, not time-tested. Now my team of facade workers does not recognize any other glue, they praise it, only 221, 222 work. It perfectly glues polystyrene, polystyrene, cotton wool, we used it even without fungi, it holds well, it does not crumble when drying. I want to note that sometimes you still need to listen to the manager-consultant and read the instructions, because failure to follow the 100% correct technological process can have dire consequences. The RedBag company is responsible for its mixtures, thank you, you helped, the problems were solved and now – everything is only according to technology…
