## A good fit for

- Small roof or felt-roof repair jobs where a 500ml quantity and grey finish suit the task.
- DIY buyers seeking a liquid coating listed for multiple roof materials and one-coat use.

## Less suited to

## Customer feedback

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.
- Positive themes: Customers describe application as easy, particularly on felt roofs.
- Positive themes: Feedback includes reports of leak prevention, waterproofing and a pleasing finish.
- Mixed feedback: Drying time and thickness receive mixed reports, including both quick-drying experiences and reports of poor drying or difficulty applying a thin layer.
- Mixed feedback: Value for money opinions vary.
