• Cleaning: The surface to be treated must be clean and free of dust. Dust, dirt, oil, paint, and other contaminants can prevent proper adhesion of the material. The surface should be cleaned by sweeping, brushing, or vacuuming.
• Removal of Old Coatings and Weak Layers: If there are old waterproofing materials, paint, or other coatings on the surface, they must be completely removed. The presence of weak or loose layers can hinder effective adhesion.
• 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 materials should not be applied to damp surfaces. The surface must be within specific moisture content limits before application.
• Surface Water Absorption: If the application surface is concrete, it is important to check its water content. The concrete should 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 surface’s water absorption capacity.
• 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.
