SUBSTRATE PREPARATION
Substrates must be free of standing water (no puddles) clean and free of all contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.
All existing coating / membrane, dust, loose and friable material must be completely removed from all surfaces before application of SikaCoat®-300 Cool, and associated system products, by industrial vacuuming equipment.
The substrate must be sound and of sufficient strength. Weak concrete must be removed and surface defects such as blowholes and voids must be fully exposed.
To confirm adequate surface preparation and product adhesion, carry out a trial before full application together with adhesion tests.
MIXING
Mix SikaCoat®-300 Cool (manually or with a low-revolution mixer) until it is completely homogeneous.
APPLICATION
Dilute SikaCoat®-300 Cool with 15–20 % of clean water. Stir gently until the mix is homogenous and a uniform colour is achieved. Using a short hair wool roller, brush or by airless spray, apply a layer of the diluted SikaCoat®-300 Cool 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®-300 Cool 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.
