Polymer-reinforced ready-made mortars with high strength are defined as cement-based repair mortars. Water and frost resistant repair mortars have different aggregate distribution, different fluidity, and different adherence values for different purposes.
Repair crosses are used to repair various damages on the structures. It is preferred to obtain a smooth and crack-free surface before painting on large surfaces. Repair mortars, which are quite easy to apply, are widely preferred due to their high strength.
Where Are Repair Mortars Used?
Repair mortars are available in two different types: as thin and thick. Fine repair mortars are preferred in interior spaces; plaster cracks and holes repairs, for plastering of liquid and concrete areas for leveling purposes. Thick repair mortar is used for plaster, crack repair, repair of thick cracks, plastering of liquid and concrete surfaces to make them flat, to create a smooth bottom surface before ceramic.
How to Use Repair Mortars?
The surface to be used in repair mortars must be cleaned of dirt, dust, paint and substances that will prevent adhesion. If there are loose parts on the surface, it should be cleaned. The surface on which repair mortars will be applied should be moistened with water.
After the area where the repair mortar will be applied is humidified, the application can be started. In order to increase adherence on smooth surfaces, the surface primer is applied to the surface with a brush. The appropriate amount of water is added to the mixing bowl and the powder material is added. Mixing is carried out with a low-speed hand mixer.
The mortar prepared to smooth the surface is applied to the surface through a steel trowel. Application thickness is 3-5 mm in thin repair mortar and 5-10 mm in thick repair mortar. Two layers of application are made to achieve a thicker application. The second coat is made after the first coat is dry.
Plaster parts are cleaned during repair operations. A section about 10 mm deep in the crack area is formed and the filling process is performed with a mortar trowel. After hardening the filling, the surface can be covered with a trowel.
No material (gypsum, cement, etc.) should be added into the mortar prepared in repair mortars. Expired mortars should not be mixed with water and dry mortar and reused. Since repair mortars are cement-based, gloves should be used when applying the material.
