a) Surface Preparation:
Take care that the application surface should be solid, dry, carrier, dust-free and clean and at the same time in balance. The surface should be thoroughly cleaned of all kinds of oil, grease, rust and paraffin residues that will weaken the adherence and there should be no loose particles on the surface. Damaged surfaces with a depth of 5 to 20 mm should be repaired with Lotti Repair Mortars two days in advance. If the temperature of the surface to be applied is above + 25°C, the surface should be moistened.

b) Product Preparation:
The water in appropriate amount is poured into the clean mixing vessel with a scale. 1020 Serafast is added slowly and mixed with a 400-600 rpm mixer for 3-5 minutes until a uniform and lump-free mixture is obtained. After resting for 3-5 minutes and mixing again for 30 seconds, the material is ready for use.

c) Application Method:
1020 Serafast layer of 1 mm thickness is applied to the application surface with the flat side of the trowel. 1020 Serafast is applied in one direction in such a way that a uniform thickness is obtained with the toothed side of the trowel to an area that can be covered within 30 minutes, open waiting time. For the bonding of tiles or ceramics with different thicknesses, it is recommended to apply 1 mm thick mortar under each tile or ceramic in order to cover the defects on the application surface. When applying tiles or ceramics in place, the tiles or ceramics are floated in the mortar to ensure that the 1020 Serafast is fully in contact. Application is completed by leaving the recommended joint gap according to the appropriate tile or ceramic size. Lotti Joint Fillings should be used to fill the left joint gaps. Joints can be applied after approximately 24 hours.
