Casco OneFill Premium is a very lightweight, universal ready-to-use filler for filling and repairing larger and smaller cracks, joints, and holes. Suitable for openings up to 50 mm; does not shrink as it dries; easy to sand; suitable for use with most materials (wood, brick, concrete, metal, OSB, drywall) both indoors and outdoors. Fastening elements (screws, nails) can be driven into the repaired areas. Application temperature: +5°C to +30°C; maximum layer thickness: 50 mm. Before application, remove all loose particles, dust, and moisture from the substrate. After opening, mix the product thoroughly; gaps larger than 50 mm must be filled in several stages. To achieve a uniform finish, use Casco MultiFill finishing putty during finishing. In outdoor environments, the cured putty must be covered with at least two coats of paint. Not suitable for use in areas constantly exposed to water. Temporary exposure to moisture is permitted 24 hours after installation.
