It is used to ensure that waterproofing membranes adhere to the surface more firmly and without gaps.

• Cleaning: The surface to be treated must be clean and dust-free. Dust, dirt, oil, paint, and other contaminants can prevent proper adhesion of the material. The surface should be cleaned using sweeping, brushing, or vacuuming.
• Removal of Old Coatings and Weak Layers: If the surface has old waterproofing materials, paint, or other coatings, they must be completely removed. The presence of weak or loose layers can hinder effective adhesion of the material.
• Correction and Filling: If there are cracks, holes, or other irregularities on the surface, they should be corrected using a suitable repair material or filler. A smooth surface ensures uniform application of the waterproofing material.
• Moisture Control: The moisture content of the surface should be checked. Waterproofing material should not be applied to damp surfaces. The surface must be within specific moisture content limits before application.
• Surface Water Content: If the surface to be treated is concrete, it is important to check the water content of the concrete. The concrete must be sufficiently dry; otherwise, the adhesion performance of the waterproofing material may be negatively affected.
• Primer Application (Optional): In some cases, a primer may be applied to the surface. The primer helps improve adhesion, seal rough surfaces, and control the water absorption capacity of the surface.
• Pre-Application Test: After surface preparation is complete, a small test application can be performed before applying the waterproofing material. This test ensures proper adhesion and suitability of the material.

• The primer should be applied evenly and homogeneously on the surface.
• Allow at least 24 hours for the primer to fully dry.
• A single coat of primer is sufficient.
• Can be applied using a brush or roller.

• The air temperature during application should be above +5°C.
• Application is not recommended in rainy or humid weather conditions.
• If bitumen comes into contact with the skin, it should be thoroughly washed with soap and water.
• If bitumen gets into the eyes, rinse with water for at least 15 minutes and seek medical advice.
• If bitumen is inhaled, move to fresh air and consult a doctor.
• The primer should be stored in a place inaccessible to children and pets.
• Used primer packaging should not be recycled and must be disposed of as waste.
• After application, hands and face should be thoroughly washed with soap and water.
