Apply 3mm to 30mm neat, up to 50mm with aggregate
Suitable for warehouses and factories
Abrasion resistant for industrial environments
Can also be used as a base for coatings
Application
Mechanically prepare the concrete by scabbling, grinding or shot blasting to expose the aggregate, then vacuum thoroughly. Prime with ARDEX R 3 E or R 5 E epoxy primer, sand-blinded with ARDEX Fine Aggregate. Mix each 25 kg bag with up to 4.5 litres of clean water, no more. Pour onto the primed floor and allow to self-level (working time approx. 25 minutes at 20°C), using an ARDEX Pin Leveller for thicker applications and a spiked roller to finish. Apply at 5°C or above. Seal or resin-coat to protect against oil, salts and water. Internal use only: not for external areas or areas subject to wetting.
Coverage
25 kg bag. Approx. 1.78 kg/m² per mm thickness, about 4.7 m² at 3mm per bag.
