What material can you use to cover openings to prevent overspray?

Using polyethylene sheets to cover openings and prevent overspray is an effective choice due to their durability and ability to create a tight seal, minimizing the risk of paint particles escaping to unwanted areas. Polyethylene sheets are also resistant to moisture and other elements, which makes them suitable for both indoor and outdoor painting applications.

While plastic bags can be used for small items or intricate areas, they may not provide the same level of coverage and security as polyethylene sheets. Newspaper is often utilized for protecting surfaces, but it is less resistant to moisture and can tear easily, making it a less effective option for creating barriers against overspray.

Using polyethylene sheets provides a reliable and professional standard method for ensuring that overspray is adequately contained, thus leading to a cleaner and more efficient painting process.
