The solution took three steps. In the first step, loose and labile parts were stripped away. After thorough cleaning, the existing blemishes were filled in with 3250 kg of UZIN ER 200, a reactive resin screed, and the special filler UZIN XS. The 2-component epoxy resin moisture barrier was able to be applied in the second step once the overhanging areas had been subsequently bevelled. This ensures that the areas close to the ground can’t release moisture into the floor coating. 580 kg of UZIN PE 480 were used for this. During the second coating, 2500 kg of UZIN fine sand 0.3 was sprinkled on as a bonding agent. The expansion strips that were subsequently added ensure that no sound can carry through the walls and columns. To prepare the floor for the final step, trowel application, 525 kg of UZIN NC 118 gypsum repair compound was used to fill in the deep eruptions and holes. Particular precision was needed here, because the carpenter had already finished the furnishings. So 5800 kg of self-levelling gypsum smoothing compound was spread on at a perfectly uniform height, 850 m² of UZIN Multimoll Top 4 stress-relief mats were inserted, and rolled over with 100 kg of 2-component PUR wood flooring adhesive UZIN MK 92 S.
