## Before you buy

- The listing details are inconsistent about length: the title and size field state 100mm x 4m, while Unit Count says 5.0 meter. Surface compatibility also differs between entries, with concrete appearing only in the surface recommendation. Confirm the selected listing's roll length and intended surface before purchase. Customer feedback also describes mixed adhesion and water-resistance results, so performance for a particular leak is not assured.

## In the box

- 1 x waterproof butyl tape (Included)

## A good fit for

- People seeking a butyl tape roll for outdoor roof, gutter, shed or caravan repair where the listed material and dimensions fit the job.
- Buyers who want a tape listed for use on metal, plastic, glass or concrete.

## Less suited to

- Buyers who need a confirmed 5m roll, since the listed size is 100mm x 4m but another detail says 5.0 meter.
- Anyone needing guaranteed leak-stopping performance, as customer feedback on stickiness and water resistance is mixed.

## Customer feedback

Customer feedback highlights ease of use, versatility and functionality, with some customers reporting durability lasting up to two years. Reports on stickiness and water resistance are mixed, including both successful adhesion to plastic guttering or conservatory roofing and cases of poor adhesion or water coming through. For an outdoor repair, this matters because the listing's waterproof claim and compatible-surface details do not guarantee the same result on every job.
- Positive themes: Customers describe the tape as easy to use and versatile.
- Positive themes: Some customers report it remains strong for up to two years.
- Negative themes: Some customers report that the tape has little or no stickiness.
- Negative themes: Some report that water comes through rather than being stopped.
- Mixed feedback: Customers' accounts of adhesion and water resistance vary, including both successful leak stopping and unsuccessful results.

## Frequently asked questions

### What size is the DIY Doctor DD-BUT tape?
The title and size detail give 100mm x 4m. Another listing detail says 5.0 meter, so confirm the roll length on the selected listing.
### Which surfaces does the listing recommend?
The surface recommendation names metal, plastic, glass and concrete. A separate compatible-material entry lists glass, metal and plastic, so concrete is not repeated there.
### Is the tape intended for outdoor use?
Yes. The listing gives Outdoor as its recommended use and describes the tape as waterproof and weather-resistant.
### Do customers report consistent adhesion and water resistance?
No. Customer feedback is mixed: some report good adhesion and leak stopping, while others describe poor stickiness or water coming through.
