Hello! In his househe poured the floors with a cement screed, then decided to level them with the TERRACO Terraskrid bulk floor. I spread it according to the instructions, as it is written on the bags, poured it, but now as the third day they have not dried. Question: can a cold base be the cause?

Good afternoon, Konstantin!
TERRACO Terraskrid self-leveling coating has a unique composition with aluminum cement and plastic copolymers, which provide it with quick setting, high strength and ductility. To completely harden the solution layer up to 10 mm thick, the manufacturer sets the time to 24 hours and indicates that the mixture is suitable for creating monolithic substrates during repair work in dry and wet rooms, as well as inside and outside buildings.
Such a long stay of the self-leveling bulk floor in the liquid phase most often occurs for three reasons. First - the technology of preparation of the composition is violated. Since you say that you did everything exactly with the instructions, we will consider this factor insignificant. The second reason is the excess of the recommended thickness of the composition or the use of a bulk floor at low temperatures, when its thermal crystallization occurs. As for temperatures above +5 ° C, such mixtures show excellent adhesion and polymerization. The third circumstance may be the excess of the term or storage conditions of the composition in the distribution network. When buying, you should check how long TERRACO Terraskrid lay on the shelves of the store. Do not forget that the manufacturer has set a deadline for the storage of dry mix in 12 months. In addition, when opening the package, be sure to pay attention to the appearance of the composition - there should not be lumps in it that indicate that the floor leveler was stored in high humidity. Do not throw off the scales and the factor of factory defects or falsification of self-leveling coatings - everything is possible nowadays.
