Usage Instructions

ARDEX E 75 is prepared by mixing with water as needed and added to the relevant mortar as mixing water according to the table below.

When used as a primer slurry with ARDEX A38 Hydraulic Binder, 25 kg of ARDEX A38 is mixed with 25 kg of 0-5 mm sand and 50 liters of E 75 to achieve a slurry consistency.

If used as a bonding agent, it should be mixed with powder product and sand, then applied with a brush by pressing firmly. The main mortar should be applied while the surface is still fresh, using the wet-on-wet method.

For such applications, ensure the surface is free from separating agents, and clean and roughen surfaces treated with surface hardeners or formwork oils before application.

Apply at temperatures above +5°C.
