3M 7000051821 Scotchblok Masking Paper 12x180

Product Description

The 3M 7000051821 is a Scotchblok masking paper roll designed for use in paint masking applications where clean, defined edges and bleed-through protection are required. The roll measures 12 inches wide by 180 feet long, providing substantial coverage per roll. It is lightweight at 1.928 pounds per roll, making it easy to handle during prep work. HVAC, plumbing, and general construction contractors use masking paper during painting, coating, and surface protection tasks on job sites and in finished spaces. Professional painters and trade contractors rely on this format for consistent, repeatable masking setups.

This masking paper is suited for residential and light commercial applications where surfaces require protection from overspray, drips, or incidental paint contact. The 12-inch width is a common size for masking trim, ducts, fixtures, and other moderate-width surfaces. It is sold individually per roll with a minimum order quantity of 12 rolls per case, making it appropriate for stocking at supply houses or ordering for larger project needs.

Installation Notes

Masking paper is applied by painters, finish carpenters, and general trade contractors during surface prep. Secure the paper with appropriate masking tape along all edges to prevent paint migration. Remove masking paper promptly after the coating reaches the recommended flash or dry stage to avoid edge tearing or paint peel. Store unused rolls horizontally in a dry location to prevent moisture absorption and deformation.
