Weberfloor LVL 100 Multi
Weberfloor LVL 100 Multi is a cement-based, fiber-reinforced, self-leveling screed that can be applied in thicknesses ranging from 10 mm to 100 mm. It provides a practical, durable, and reliable solution, particularly for floors with significant level differences and renovation projects. Thanks to its low-shrinkage and non-swelling formulation, it creates stable and long-lasting surfaces.
Product Description
Weberfloor LVL 100 Multi is a cement-based, fiber-reinforced self-leveling screed designed for application thicknesses between 10 mm and 100 mm, offering high mechanical strength and excellent leveling performance.

Areas of Application
- Interior floors exposed to medium and heavy pedestrian traffic
- Floor leveling before ceramic tiles, stone tiles, parquet, and carpet installation
- Preparation of substrates for thin floor coverings such as PVC and linoleum (additional fine leveling may be required)
Suitable Substrates
For indoor use on:
- Cement-based screeds
- Concrete slabs
- Precast concrete surfaces
Surface Preparation (Bonded Application)
- The substrate must be clean, dry, and sound.
- Paint, plaster, adhesive residues, and contaminants must be removed.
- Sweep or vacuum the surface to eliminate dust.
- Damaged areas should be repaired with appropriate repair mortars.
- Cracks should be reinforced with floor mesh where necessary.
- Apply a suitable primer before installation.
Application Over Insulation Boards
- XPS, EPS, or mineral wool boards must be installed without gaps.
- Waterproofing should be applied to the substrate beforehand.
- A polyethylene (PE) sheet should be placed over the insulation layer, with joints properly sealed.
- Edge insulation strips should be installed around the perimeter.
- Reinforcement mesh should be laid with proper overlap.
Application Over Underfloor Heating Systems
- The insulation layer must be installed correctly.
- Structural load calculations should be completed beforehand.
- Expansion joints must be maintained.
- Perimeter insulation strips should be installed.
- Reinforcement mesh should be placed over the protective membrane.
Application Conditions
- Application temperature: +5°C to +30°C
- Do not apply on frozen surfaces or surfaces at risk of freezing.
- Protect from direct sunlight and strong wind.
- Application in enclosed and controlled environments is recommended.
Application Instructions
- Mix 25 kg of product with approximately 4 liters of water.
- Blend with a low-speed mixer until a homogeneous consistency is achieved.
- For manual applications, keep the working width to approximately 3 meters.
- If necessary, level the surface using a screed bar or leveling tool.
- Freshly poured material should be joined with the previous section before initial setting occurs.
Consumption
Approximately 1.9–2.0 kg/m² per 1 mm thickness.
