## Before you buy

- The listing has inconsistent colour information: the title and colour field say black, while the colour code and product note describe clear liquid. Its listed spray application also differs from the paint-on instructions, and the 24.0-hour drying-time field does not specify conditions. Confirm the selected item and follow its container instructions.

## In the box

- Waterproofing can (Included)

## A good fit for

- Tent, awning and other outdoor-fabric owners seeking a large-volume brush-on water-repellent treatment.
- Buyers who want a treatment listing UV protection and are prepared to apply it to clean fabric and allow it to dry fully.

## Less suited to

- Anyone needing a confirmed colour-matched product without checking whether the liquid is clear or black.
- Buyers seeking an immediately ready-to-use spray bottle, since the listing describes decanting into a pump sprayer rather than including one.

## Customer feedback

Customer feedback highlights perceived water repellency, ease of application and drying, with some people also noting low odour and good value for the larger can. These reports are relevant to the listed brush-on liquid treatment, but experiences with leakage differ, so the claims should not be treated as a guarantee for every tent or application.
- Positive themes: Customer feedback describes water beading and ease of application, including use with a garden sprayer.
- Positive themes: Some customers report satisfactory drying and low odour.
- Mixed feedback: Feedback on leakage is mixed, with reports of both dry tents and water getting through roofs.
- Mixed feedback: Odour is described as low by some customers, while overall feedback on odour is mixed.

## Frequently asked questions

### How is this Fabsil treatment applied?
The listing instructs applying it to clean fabric with a clean brush using long, even strokes. Wipe away excess and let the treated fabric dry completely before use.
### Can it be applied with a sprayer?
The listing says it can be decanted into a pump sprayer and applied on a fine-mist setting from roughly 10–15 cm away. A sprayer is not listed as included.
### Is the liquid black?
The listing conflicts: the title and colour field say black, but another note says the tin is black and the liquid inside is clear. Check the selected listing or container details if colour matters.
### How long does it take to dry?
A details field gives a drying time of 24.0, without stating the conditions. The application instructions say to let the material dry completely before use.
