Usage

Open windows and doors for ventilation and protect surrounding areas with dust sheets. Remove wallpaper or loose paint and clean the surface, removing mold if present. Stir the damp seal well before use. You can apply it onto damp surfaces, ensuring the area is not dripping wet. For small damp patches, paint at least 30cm around the area. After application, it will be touch dry in 1-2 hours and ready for painting or wallpapering in 4 hours. Clean brushes or rollers in warm soapy water. If mold-prone areas exist, consider additional anti-mould products as needed.

Ensure the cause of damp has been addressed before application. Ventilate well during use and protect surrounding areas. Do not apply to surfaces that are dripping wet.
