Coal tar sealant prohibition

Definition

A state ban on both applying and selling the cheaper sealer used on asphalt.

Why It Matters

Minnesota prohibits both applying and selling coal tar sealant products on asphalt-paved surfaces, and defines the product by three chemical identifiers, so a supplier's relabel does not move it. The exemptions are narrow and none of them covers commercial work: research, and developing an alternative technology. A sealcoating book priced in a state that still allows the cheaper product is priced off a different cost of goods than the same book next door. Ask what the crew actually puts down, what it costs per square foot, and whether any account sits across a line the seller has not noticed.
