Sika Sikalastic-800 HA

Sikalastic®-800 HA – Solvent-Free, Hand-Applied Liquid Waterproofing for Roofs & Podiums

Sikalastic®-800 HA is a two-component, solvent-free, highly elastic polyurea liquid membrane designed for seamless waterproofing of flat roofs, balconies, terraces, podium decks, and walkways. This virtually odourless system is cold-applied and hand-applied without the need for spray equipment, making it ideal for smaller projects up to 150m².

Thanks to its self-levelling properties and high crack-bridging capability, Sikalastic®-800 HA forms a joint-free, fully bonded waterproofing layer that resists ponding water. It can also be topped with an aliphatic coating for UV protection on exposed surfaces.

Key Benefits:

• Cold-applied & Self-Levelling – Simple to install using a notched squeegee

• One-Layer Application – Achieves desired thickness in a single coat

• Virtually Odourless – Suitable for sensitive or occupied environments

• Highly Elastic – Adapts to structural movement with excellent crack bridging

• Water & Weather Resistant – Long-term durability, even with ponding water

• Great Substrate Adhesion – Bonds well to most common surfaces

Typical Uses:

• Flat roof waterproofing & repair

• Balconies, terraces & walkways

• Buried roofs and podium decks

• Cost-effective solution for smaller areas without spray equipment
