Instructions
Applications
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
as well as for filling, smoothing, and leveling of unheated, cement based substrates under:
- SCHÖNOX Moisture Mitigation Systems
Priming
- porous substrates such as:
- concrete, cement substrates
- OSB board, plywood (well screwed and/or bonded)
- no priming required
- non porous substrates such as:
- ceramic tiles (thoroughly cleaned and abraded)
- terrazzo
- water-resistant adhesive residues (removed as far as possible)
- no priming required
- gypsum substrates (sanded and vacuumed)
- prime with SCHÖNOX KH FIX
Mixing Ratio
- mix each 4.5 kg / 10 lb. bag with 1.9 liters / 2.0 quarts of water
Recommended Method of Working
- 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 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.
Instructions
- Do not use in areas of constant water exposure (such as interior swimming pools).
- Always install an adequate number of properly located test areas, to include the finish flooring, to determine the suitability of the product for its intended use. As floor coverings vary, always contact and rely upon the floor covering manufacturer for specific directions such as maximum allowable moisture content, adhesive selection, and intended end use of the product.
- Low substrate temperatures and/or high ambient humidity require longer drying times.
Storage
- Store in cool and dry conditions.
- Shelf life: 12 months unopened.
- End of shelf life does not generally indicate the end of the products suitability for the intended use. Always test in a small area.
Disposal
- Empty packaging and dispose of in accordance with federal, state, and local waste disposal regulations.
Precautions
- SCHÖNOX SL contains Portland cement. Avoid eye and skin contact. In case of contact, rinse immediately with plenty of water. In case of contact with eyes seek additional medical advice. Mix in a well ventilated area and avoid breathing powder or dust.
- Never mix with cement or additives other than SCHÖNOX approved products. Observe the basic rules of concrete work. Do not install below 41ºF surface temperature install quickly if substrate is warm.
