Polycell Damp Seal Aerosol

The Polycell Damp Seal Aerosol is a specialist sealing treatment designed to tackle penetrating damp on interior walls and ceilings. This professional-grade formula creates an effective barrier that prevents damp patches from showing through and spoiling decorative finishes, delivering reliable protection in just one coat. Formulated specifically for use on plaster, cement and stone surfaces, this aerosol application provides convenient, controlled coverage for treating localised damp problems. The sealed surface becomes touch dry in approximately 4 hours depending on conditions, allowing for efficient project turnaround. The matt white finish can be overcoated with paint or wallpaper, making it ideal for contractors and decorators preparing surfaces for final decoration. This damp seal aerosol is particularly suited to repair and maintenance work where penetrating damp has compromised interior surfaces. The single-coat coverage makes it an efficient solution for preparing walls and ceilings prior to redecoration, whilst the aerosol format allows for precise application to affected areas.
