SCHÖNOX® SL Cement Based Rapid Drying, Smoothing and Finishing Compound
- EMICODE EC 1PLUS R: very low emission
- For interior use only
- Featheredge achievable
- Fast drying in all thicknesses
- Suitable for underfloor heating systems
Product Information
SCHÖNOX SL is a cement-based rapid-drying smoothing and finishing compound. It is designed to provide a smooth finish on various substrates in interior areas. SCHÖNOX® SL can be installed as a true featheredge.
SCHÖNOX SL provides exceptional hardness and strength. It is fast-drying in all thicknesses, making it a great choice for projects with tight timetables.
SCHÖNOX SL produces a very smooth surface. It is moisture resistant (interior only). There are no moisture vapor emission limitations on properly prepared concrete.
SCHÖNOX SL is suitable for use with underfloor heating systems. It can also be used for castor wheels loadings according to DIN EN 12529.
SCHÖNOX SL is suitable for patching, smoothing and leveling of:
- Concrete, cement substrates
- Floor leveling compounds
- Gypsum substrates
- Old substrates, such as ceramic tiles
- Old, water-resistant adhesive residues
- Wooden substrates
SCHÖNOX SL can also be used for filling, smoothing, and leveling of unheated cement-based substrates under SCHÖNOX Moisture Mitigation Systems.
This compound is rated EMICODE® EC 1PLUS R for very low emissions.

Usage
Mixing Ratio:
Mix each 4.5 kg/10 lb bag with 1.9 liters/2.0 quarts of water.
Recommended Working Method:
- Using a clean mixing bucket, add SCHÖNOX SL to cold, clean water to form a homogeneous mixture.
- Mix thoroughly for approx. 3 minutes using a heavy-duty drill (min. 600 RPM) to obtain a lump-free mix. Or mix smaller volumes by hand approx. 2–3 minutes to consistency.
- Apply, smooth and shape the leveling compound using a stainless steel smoother or a smoothing trowel. Do not mix more material than can be applied within 15 minutes.
- Protect curing SCHÖNOX SL layers from high ambient temperatures, direct sunlight and draughts.
- Clean tools in water immediately.
