Product Description:
SikaCoat®-333 is an elastic, self-priming, acrylic-based liquid-applied membrane with solar-reflective properties that reduce heat absorption, helping to lower building temperatures and improve energy efficiency.
Usage:
Waterproofing applications:
- Flat and sloping full exposed roof structures
- New construction and refurbishment projects
- External walls
- Roofs with numerous details (eg.: penetrations, drains, roof lights, and complex geometry)
Compatible substrates:
- Concrete, mortar, and cement-based materials
- Brick and roof tiles
- Metal surfaces (steel, zinc, aluminium)
Features / Advantages:
- High UV resistance and solar reflectivity for energy efficiency
- Eco-friendly, water-based, and non-toxic
- Bridges micro cracks and bonds well to various substrates
- Elastic waterproofing with superior coverage
- Easy application by roller, brush, or spray.

Application Steps:
Step 1 : Substrate Preparation
- Ensure substrates are free of standing water, clean and free of all contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.
Step 2 : Mixing
- Mix SikaCoat®-333 (manually or with a low-revolution mixer) until it is completely homogeneous.
Step 3 : Application
- Dilute SikaCoat 333 with 15-20% of clean water.
- Stir gently until the mix is homogenous and achieve uniform colour.
- Apply a layer of diluted SikaCoat 333 using a short hair wool roller, brush or airless spray onto the substrate, observing how it penetrates well in all the cracks.
- After the primer has dried (> 3 hours at +30 °C), apply successive layers of SikaCoat 333 to the desired film thickness.
- Ensure the previous layer is completely dry before the next layer.
Step 4 : Cleaning of Tools
- Clean all tools and application equipment with water immediately after use.
- Hardened material can only be removed mechanically.
