MIXING

SikaCeram®-450 H must be mixed with clean water using a hand-held or mechanical mixer for 3–7 minutes until a homogenous lump-free paste is achieved. The wet mix should be use within 30–45 minutes after mixing.

 

APPLICATION

Apply SikaCeram®-450 H onto moist, clean substrate using a wooden/steel float or steel trowel while the mix is still workable. It can be applied at a recommended thickness of 2–40 mm. SikaCeram®-450 H should be cured for at least 7 days prior to any tiling works.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened or cured material can only be removed mechanically.
