Concrete Surface Repair: One of the most common applications is repairing cracks, holes, or other damages on concrete surfaces. Fine repair mortars enhance the durability of concrete and improve its aesthetic appearance.
Wall Repair: Small cracks or damages on walls can be corrected to achieve an aesthetic appearance. It can also be used to smooth or level walls.
Surface Smoothing: Can be used for correcting or leveling rough concrete surfaces. It is particularly preferred for improving rough surfaces on floors or walkways.
Expansion Joint Filling: Expansion joints are used to accommodate the expansion or contraction movements in structures. Fine repair mortars can fill these joints, forming a barrier against water and other external factors.
Stair and Step Repair: Can be used to repair cracks or damages on concrete stairs or steps.
Corner Repair: Cracks or damages in wall corners can be corrected using cement-based fine repair mortars. This is important for ensuring structural integrity and achieving an aesthetic look.

Cleaning: The surface should be thoroughly cleaned to remove dust, dirt, oil, paint residues, and other contaminants.
Removal of Weak Concrete and Loose Parts: If there are weak or detached concrete pieces, these areas should be cleaned and reinforced with a suitable repair material.
Surface Smoothing: Before application, it is important to smooth the surface. This ensures proper adhesion of the mortar. Worn or rough surfaces should be corrected with a special primer or leveling coat if necessary.
Moisture Control: The moisture content of the surface should be checked before application. In most cases, the moisture level should be below a certain threshold. Excessive moisture can negatively affect the adhesion and hardening properties of the mortar.
Surface Should Not Be Wet: Before application, ensure that the surface is not wet. Wet surfaces can adversely affect the adhesion capability of the mortar.

25 Kg. Pratech®RP20 Thick Repair Mortar should be poured slowly over approximately 5.50 Lt. water and mixed thoroughly until the mixture has a homogeneous consistency. Apply the prepared thin repair mortar evenly on the application area using a trowel or a trowel-like tool. Care should be taken to spread the mortar homogeneously on the surface. After the mortar is applied, the mortar should be leveled and shaped using a trowel or spatula. This step ensures that the mortar surface is flat and in the desired form.

Protect your skin, eyes and respiratory system when working with mortar. When mixing mortar, use a low speed mixer to minimize dust formation. When preparing mortar indoors, ensure adequate ventilation or use a respiratory mask. Use clean and dry containers for mixing the mortar. Do not add any foreign matter to the mortar. Do not apply mortar in extremely hot or cold weather.
