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.

On Plaster Based Surfaces,
Lotti Plaster is applied on gypsum-paper board, gypsum-plaster, gas concrete, lime stuff and chipboard with high absorbency. Adhesion can be started 5 minutes after the primer application.

Wood Particleboard Surfaces (OSB and Chipboards),
Wood particleboards should contain a maximum moisture content of 10%. Wood particleboard (V100) applied to the floors should be minimum 25 mm and 19 mm for the walls. The boards should be screwed to the surface at 30 cm intervals. The edge joint must be at least 8 mm wide. At the joints of the chips, grooves should be opened and filled with Joint Sealant. Wood paperboards should be primed with Lotti Plaster in dry environments.

If the boards are in place that exposed to moisture (exterior), it is applied with Fully Flexible Waterproofing Material in two layers and mesh reinforced.

b) Product Preparation:
The water in appropriate amount is poured into the clean mixing vessel with a scale. 1013 Flex Mortar 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:
1013 Flex Mortar layer of 1 mm thickness is applied to the application surface with the flat side of the trowel. 1013 Flex Mortar 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 1013 Flex Mortar 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.
