SikaCoat®-555 is a water-based, one-component liquid waterproofing coating with self-priming and microfiber reinforcement. It creates a flexible, durable waterproof membrane suitable for various applications.

– Microfiber reinforced acrylic for flexibility and durability.
– Resistant to micro cracks with excellent penetration.
– High UV resistance and solar reflectivity for energy efficiency.

Usage

Waterproofing applications:

– Flat and sloped exposed roofs
– New and refurbishment projects
– External walls
– Roofs with complex details (e.g., penetrations, drains, skylights)

Compatible Substrates:

– Concrete, mortar, and cement-based materials
– Brick and clay roof tiles
– Metal surfaces (steel, zinc, aluminium)

Advantages

– Microfiber reinforced acrylic for flexibility and durability.
– Resistant to micro cracks with excellent penetration.
– High UV resistance and solar reflectivity for energy efficiency.
– Eco-friendly, water-based, and non-toxic.
– Bridges cracks and bonds well to various substrates.
– Elastic waterproofing with superior coverage.
– Easy application by roller, brush, or spray.

MIXING

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

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.
