Purchase 21POLYtm

Because of the elaborate mixing and application equipment required, the 21POLY coating process is not something you can do at home. 21POLY is applied by a licensed Applicant and is usually the same company that treated the lumber. In some cases, there may be a mobile applicator near you who can apply the product on site.

21POLY can be purchased either directly from Northstar or from a 21POLY Licensee.

Lead time: Popular items are usually in stock. For unique parts, allow three to nine weeks.
