• Self-adhesive butyl-plaster for sealing of window sill corners
• Oval 60 x 50 mm
• Second sealing layer recommended
The self-adhesive butyl-plaster is suitable for simple, localised sealing of the critical joint between the window sill screw mounting edge and the end piece for plaster walls or clinker brickwork against water ingress. The bonding areas concerned must be dry and free from dust and grease before the adhesive is applied. Attached correctly with the opening facing downwards. An additional, second sealing layer is recommended to ensure that the window sill withstands driving rain.
