Advantages
- Long life waterproofing product (min 20 years).
- Resistant to a wide temperature change from — 40 derajat Celcius to 130 derajat Celcius without cracking and peeling
- Environmentally friendly
- Excellent heat, Ozone and UV resistant
- Dark color carbon in EPDM black is the compound for UV protection giving reinforcing the membrane form UV and weathering exposure.
- Titanium dioxide pigment in EPDM white is typically used to reflect UV rays.

Application Instructions
Surface Preparation
New concrete on cementitious substrates should be at least 28 days old and dry surfaces existing concrete floors which required refurbishment must be prepare to ensure smooth surface, flat and strong adhesive bond between substrate and Estoproof EPDM membrane. Substrate must be dry and free of contamination such as oil, grease, loose particle etc.
A. Mechanically fastened Systems
This is a simple and easy application system where the Estoproof EPDM membrane is loosely laid over existing concrete substrate. Secure it with termination bars and mechanical screws (approximately 5 screws per square meter) at 10cm overlaps, bonded with Estobond AC 221 (0.3L/m² dosage). Apply EPDM sealant to the membrane ends. Ideal for areas with moderate winds.
B. Fully Adhere bonded System
A fully adhered system offers maximum stability and uplift protection, with a range of adhesives designed for high-wind areas. Estoproof EPDM sheets must be adhered to a smooth, clean concrete surface with overlaps of 10 cm on each side using adhesive. Apply continuous EPDM sealant to the membrane ends. For detailed application methods, please refer to our guidelines.
