• Do not mix with other cement or cementitious mortars
• Protect from moisture, condensation and water after application
• Do not exceed recommended water dosage or add water after setting begins
• Not suitable for sloped surfaces
• Do not apply on gypsum-based substrates or dimensionally unstable surfaces
• This product is not a decorative finish — must be covered with final flooring
• Maintain suitable ambient and substrate temperatures for best results

FAQ

What is the maximum application thickness of Sikafloor 357 Level?

Please refer to the Sika Technical Data Sheet (TDS) for detailed thickness specifications.

How soon can you walk on it after application?

Under suitable temperature and humidity conditions, the surface becomes walkable shortly after application. Full curing takes several days — avoid rolling and dynamic loads during this period.

How do I calculate the consumption?

Consumption depends on application thickness. Refer to the Sika TDS for detailed coverage rates. Actual consumption will vary with substrate condition.

Can it be used outdoors?

No. Sikafloor 357 Level is for indoor use only.

Is a primer needed?

Depends on the substrate. Low-porosity concrete should use a suitable primer. High-porosity substrates should use Sikadur-732. Primers improve adhesion and prevent bubbles.
