Gypsum filler UNIFLOTT 25 kg

Properties: - loose, ready-to-use mortar (just pour into water and mix), - the possibility of obtaining a homogeneous mass, - good adhesion, - particular ease of processing in the form of putty, - based on special gypsum, - quick strength increase, - quick drying, - high water retention capacity, - low shrinkage related to drying, - easy cleaning of tools and equipment, - non-flammable. Preparation: Boards and dry screeds should be permanently attached to the load-bearing structure (substrate). Their surfaces must be dry, clean and the joints free from contamination. Vidiwall boards are installed with joints 5-7 mm wide. Defects should be filled with Knauf Uniflott / Uniflott impregnated mortar. Preparation of the mortar and processing Knauf Uniflott should be poured into clean, cold water, just below the surface (max. 2.5 kg to approx. 1.2 l of water). Then, without any other additives, mix with a plaster trowel until the consistency is thick cream. Apply in at least 2 stages, depending on the required surface quality. Fill the joints, after approx. 50 minutes, remove the excess mortar. In the second stage of works, use a trowel or a wide spatula to create a smooth connection of the joint zones with the surface of the boards. Also fill the heads of drywall screws. Do not process material that is already setting. Remove slight unevenness immediately after setting. After drying, sand by hand or mechanically using a sanding mesh. Binding begins approx. 45 minutes after the material is poured into the water. Contamination of containers and tools reduces processing time. Material that is already binding should not be used, the addition of water or mixing will not make it usable again. Filling should be performed when the dimensions of the Knauf boards remain unchanged, caused by fluctuations in humidity and temperature. In the case of mastic asphalt screeds, puttying should be performed after the screed has been made. The air and substrate temperature should not be lower than 10 ° C. Only methylcellulose-based adhesives may be used. After wallpapering with paper and fiberglass wallpapers and applying plasters based on synthetic resins and cellulose, it is necessary to ensure quick drying through adequate ventilation of the room. Works should be performed in dry conditions, with air and substrate temperature between + 10 ° C and + 25 ° C. All data refer to the temperature of + 23 ° C and relative air humidity of 50%. In other conditions, faster or slower hardening of the material must be taken into account.
