We have dealt with hundreds of contractors and have sold all sorts of zippers for containment purposes. The zippers that adhere the quickest are not the best. You want a zipper that adheres for a long time and for the duration of the project. We have the best adhesive than any offered in the market place. Our adhesive is not affected by cold or warm temperature, unlike the zippers of our competitors. Don’t get caught with your zipper down: ZIP-UP! Don’t forget about the new Lead Abatement rules.
