Smoothing mortar BI ULTRA SEAL

protectivewaterprooffor flooring screed

Short description
BI MORTAR ULTRA SEAL is a three-component epoxy‑cement levelling compound that forms a waterproof and capillary‑rise impermeable coating. It provides mechanical and chemical resistance and stabilises substrates for subsequent coatings.

Application categories

• Waterproofing
• Waterproof mortars - rapid-setting mortars

Key benefits

• Adheres to a wide range of substrates: effective on hardened or uncured concrete, dry or wet substrates, smooth screeds, ceramic and stoneware tiles, natural stone and plaster, and suitably cleaned old coatings
• Compatible with subsequent coatings: suitable substrate for acrylic, epoxy, polyurethane and cement‑based systems
• Improves substrate preparation: regulates surface absorption and removes dustiness of cementitious surfaces to optimise adhesion of following layers
• Application versatility: can be mixed with quartz sand to increase mechanical strength and allow greater application thickness
