MIXING
Mix SikaCoat®-555 manually or use a low speed mixer until it is completely homogeneous prior to application.

APPLICATION
Dilute SikaCoat®-555 with 15–20 % of clean water.
Stir gently until the mix is homogenous and uniform colour is achieved.
Using a short hair wool roller, brush or by airless spray, apply a layer of the diluted SikaCoat®-555 onto the substrate, observing that it penetrates well in all the cracks.
After the primer has dried (> 3 hours at +30 °C), apply successive layers of SikaCoat®-555 to the desired film thickness.
Ensure the previous layer is completely dry before applying the next layer.

CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
