Sikalastic 562

Sikalastic 562 – Advanced Liquid Waterproofing Solution for Roofs

Protecting a roof from rainwater, moisture, cracks, and weather exposure requires a waterproofing system that can perform reliably over time. Sikalastic 562 is a water-based, one-component, cold-applied liquid polyurethane waterproofing membrane designed for exposed and covered roofs. It creates a seamless waterproof finish and is suitable for new construction as well as refurbishment projects. According to the current India Product Data Sheet, the product provides UV resistance, crack-bridging capability, resistance to accumulated water, and vapour permeability.

For property owners, builders, contractors, architects, and waterproofing professionals looking for an effective roof waterproofing solution, Sikalastic 562 offers a practical coating system for a wide range of roof surfaces and complex details.

Why Choose Sikalastic 562 for Roof Waterproofing?

Traditional waterproofing methods can become difficult to maintain when a roof has multiple joints, penetrations, drains, corners, or complicated geometry. Sikalastic 562 can be applied as a liquid membrane, allowing the coating to form a continuous and seamless waterproof layer.

Its one-component formulation can be used directly from the container after appropriate mixing, while cold application means that no heat or flame is required during application. The product is also water-based and has no odour according to the India Product Data Sheet.

Key benefits include:

• Seamless liquid waterproofing membrane
• Excellent UV resistance
• Crack-bridging and elongation properties
• Resistance to accumulated water
• Cold-applied application without heat or flame
• Water-based formulation
• Vapour permeability
• Suitable for exposed and covered roofing
• Can be reinforced with geofabric where higher tensile performance is required
• Suitable for foot traffic after the specified curing period

These characteristics make it suitable for demanding roofing applications where continuous protection and flexible detailing are important.

Applications of Sikalastic 562

Sikalastic 562 waterproofing can be used across a variety of residential, commercial, and industrial applications. The manufacturer's India documentation lists flat and sloping exposed or covered roofs, concealed podiums and planter areas, external walls, old roof tile renovation, and roofs containing details such as drains, penetrations, roof lights, and complex geometries.

Roof Waterproofing

Use it for waterproofing properly prepared flat or sloping roof surfaces where a seamless liquid-applied membrane is preferred.

Terrace Waterproofing

A continuous coating can help protect terrace surfaces against water ingress when the substrate and drainage conditions are suitable.

Roof Renovation

The system can be used in refurbishment projects, including renovation of old roof tiles and other compatible existing substrates.

Podiums and Planter Areas

For concealed waterproofing applications such as podiums and planter areas, the system can form part of an appropriate waterproofing build-up.

External Wall Waterproofing

The product is also listed for waterproofing external walls where the substrate and project conditions are suitable.

Suitable Substrates for Sikalastic 562

One advantage of Sikalastic 562 is its application across several commonly encountered substrates. The India Product Data Sheet identifies concrete and cementitious substrates, brick, metal, clay tiles, unglazed ceramic tiles, bitumen sheet membranes, and bituminous coatings as potential substrates, subject to the required preparation and primer system.

Proper substrate preparation remains essential. Surfaces should be sound, clean, dry, and free from contaminants, loose materials, or conditions that could compromise adhesion. Existing coatings and substrates should always be assessed before application.

Sikalastic 562 Application Process

A successful Sikalastic 562 application depends on correct surface preparation, suitable priming, application thickness, curing conditions, and detailing.

The typical system can include a primer, two coats of Sikalastic 562, and an optional protection layer for covered roofs. Reinforcement such as Sika Fabric-50 may be recommended for larger areas, demanding applications, dynamic cracks, and joints.

For the best result, waterproofing details should be addressed before coating the main horizontal roof area. Drains, penetrations, joints, corners, and other vulnerable points require particular attention.

Performance and Technical Benefits

Sikalastic 562 is designed to provide flexibility along with waterproofing performance. The coating is also designed to withstand UV exposure and accumulated water. However, proper roof slope and drainage remain important. The manufacturer recommends suitable roof slopes and specifically advises against applications where improper slopes result in prolonged ponding.

This means the product should not be viewed as a substitute for proper roof design and drainage. A complete waterproofing solution combines the right material with correct substrate preparation, detailing, application, and curing.
