Performance Characteristics:
•Solvent-free: free from harmful substances including formaldehyde, toluene and isocyanate;
•Easy to apply: single-component coating, no pre-mixing required, convenient for on-site construction;
•Outstanding low-temperature resistance: after curing, it maintains excellent flexibility and no cracking even at - 40℃;
•Strong adhesion: excellent adhesion to various substrates such as concrete, stone, metal, glass, aluminum panels and wood;
•Excellent water resistance: no debonding after long-term water immersion.
SMT-M107 Single-component MS Waterproof Coating for Interior Use is a single-component, moisture-curingpolymeric non-exposed waterproofing material. It is applicable to building substrate surfaces. After curing, it forms an elastic waterproof layer with high strength, hydrophobicity, weather resistance, and excellent high & low temperature resistance. This material boasts the characteristics of being solvent-free, low in volatility, low in odor, and eco-friendly.

Before application:
- Compatibility tests between the coating and adjacent materials, as well as adhesion tests to the substrate to be bonded, shall be conducted prior to construction.
Construction Method:
- Clean the substrate surface to ensure it is firm, free from looseness, floating dust, loose mortar, oil stains and other foreign matters;
- Cracks and defects shall be repaired first. Fully wet the substrate before coating application, and ensure no standing water remains on the surface;
- For detail positions such as internal and external corners and pipe roots, cut polyester fabric according to the shape to make reinforcement layers, so as to avoid hollowing and cracking;
- It can be applied by scratch coating or mechanical spraying. It is recommended to apply in one coat to reach the designed thickness.
- Laying of protective layer or finishing material shall be carried out after the coating film is fully cured. Prevent sharp objects from puncturing the coating during construction.
- Use the product within shelf life; expired goods areprohibited.
- Construct strictly in accordance with adhesion testprocedures.
- Avoid direct contact with skin and eyes. Do notingest.
- Keep away from children and store out of theirreach.
- It is not suitable for use in airtight spaces, as the coating cures by absorbing moisture from the air.
- Application is not recommended when the substrate surface temperature is below 5℃ or above40℃.
- Not suitable for surfaces covered with frost or standing water.
- When bonding to cement or concrete substrates, ensure the substrate is fully dry and cured for 7 days before application; otherwise, adhesion performance will be affected.
- Not suitable for materials that may exude oils, plasticizers or solvents, such as oil-impregnated wood.
