SikaCoat®-500 Super

SikaCoat®-500 Super

Styrene-acrylic copolymer waterproof liquid membrane coating with internally reinforced micro-fibres

SikaCoat®-500 Super is a one component, water-base, liquid elastic waterproofing coating, based on styrene-acrylic copolymers with integral micro-fibre reinforcement. SikaCoat®-500 Super coating system is formulated to provide enhanced tensile strength of the coating product and forms a flexible, tough and durable reinforced protective waterproofing membrane layer. It is suitable for use in hot and tropical climates.

  • Integral micro-fibre reinforcement able to absorb expansion and shrinkage movement without cracking
  • Good penetration in cracks, and resistant to cracking
  • High weather resistance and UV resistance
  • Environmentally preferred coating: water based, non-toxic and eco-friendly
  • Elastic waterproofing membrane
  • Easy application by roller, brush or sprayed
  • Good bonding to various substrates
  • Excellent hiding power
  • Crack bridging ability

Application steps

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®-500 Super, 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®-500 Super manually or use a low speed mixer until it is completely homogeneous prior to application.

 

APPLICATION

Dilute SikaCoat®-500 Super 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®-500 Super 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®-500 Super 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.
