Technical Comparison

Application Steps

1. Surface Preparation

The substrate must be dry, clean, dust-free, and sound. A suitable primer should be applied where necessary.

2. Reinforcement of Details

Critical areas such as corners, parapets, chimney bases, and joints should be reinforced with products such as Mapeband waterproofing tapes.

3. Product Application

• Purtop Easy and Aquaflex Roof: Apply at least two coats using a roller or brush.
• Purtop 1000: Apply using specialized hot-spray equipment.

4. Waiting Time Between Coats

Depending on the product, waiting times generally range from 6 to 24 hours.

5. Protective Topcoat (Optional)

For areas exposed to heavy traffic, a UV-resistant or mechanically resistant protective topcoat is recommended.

Conclusion

The Mapei Purtop and Aquaflex product lines provide seamless, elastic, and long-lasting waterproofing solutions for both residential and industrial projects.
