Gypsum-based levelling compound for layer thicknesses from 2 to 20 mm.
CONSTRUCT Alpha SL 2–20 is a levelling system designed to create a smooth, even substrate in layer thicknesses from 2 to 20 mm. It provides an ideal base for various floor finishes such as Quartzline flooring systems, tiles, floor coverings, and parquet. Suitable for indoor applications on anhydrite, concrete, sand-cement, tiled, and wooden substrates.
Alpha SL 2–20 is low in shrinkage and stress, fast-curing, pumpable, and easy to sand after hardening. Suitable for use with underfloor heating. Not suitable for wet areas or industrial applications.
SYSTEM DESCRIPTION
Primer:
Use Primer GP for non-porous substrates and Primer Universal for porous substrates, diluted at a ratio of 1 part primer to 3 parts water.
Levelling layer:
Alpha SL 2–20 is the standard version and Alpha SL 2–20F is fibre-reinforced. Both variants can be applied in layer thicknesses from 2 to 20 mm.
Ideal for:
- Substrate for Quartzline flooring systems
- Substrate for parquet and floor coverings
- Substrate for tiles
- Renovation and levelling of existing floors
- Indoor use on various substrates
