What to know before buying

Listing details to confirm

Listing details are claims rather than independently verified performance. Customer feedback is mixed on drying time and thickness, including reports of slow or absent drying and difficulty applying a thin layer, so allow for variable results rather than relying on the quick-drying claim.

Customer feedback highlights ease of application, especially on felt roofs, and reports of leak prevention, waterproofing and an appealing finish. However, drying time and thickness are mixed points, with some reporting quick drying and others saying it did not dry or was difficult to spread thinly. For buyers considering the claimed one-coat liquid coating, this makes drying and handling less predictable than the listing's quick-drying description suggests. Value opinions are also mixed.

Mixed feedback
