## Before you buy

- Coverage is stated as an upper limit, so actual area may differ. The listing also claims up to 10 years of protection, but does not provide conditions for that duration.
- The listing details are inconsistent about compatible surfaces: the details section names concrete, stone, brick and tarmac, while feature text additionally lists block paving, slate and other natural stone. The claimed up-to-50m² coverage, one-coat application, 3-hour rainfastness, 24-hour cure and up-to-10-year protection are listing claims, not independently confirmed performance.

## A good fit for

- Owners of Indian sandstone patios, paths or driveways seeking a clear, matt sealer.
- Buyers treating an outdoor area where a stated coverage estimate and application timing help with project planning.

## Less suited to

- Buyers looking for a colour intensifier or a glossy, wet-look finish.
- Anyone needing a confirmed coverage figure for a specific stone or paving type without first resolving the listing's differing surface descriptions.

## Customer feedback

Customer feedback describes the sealer as good quality and reports positive impressions of drying time and sealing, while views on appearance and effectiveness are mixed. For buyers relying on the stated coverage and quick application schedule, those mixed reports make performance on the intended surface worth considering. The listing's coverage and curing times remain manufacturer claims rather than customer-verified guarantees.
- Positive themes: Customers report favourable impressions of product quality, sealing, value and drying time.
- Mixed feedback: Feedback on appearance and effectiveness is mixed. Some customers say it looks good and does a reasonable job, while others report that it does not perform as advertised.

## Frequently asked questions

### How much area does one container cover?
The listing states coverage of up to 50 square metres per 5 litres. Treat this as an upper limit rather than a guaranteed result for every surface.
### How long does it take to become rainproof and cure?
The listing claims it becomes rainproof in 3 hours and fully cures within 24 hours. These are product claims, not independently verified timings.
### What surfaces is it listed for?
The details section names patio surfaces and compatible materials including concrete, stone, brick and tarmac. Feature text also mentions block paving, slate and other natural stone, so confirm suitability for the specific surface.
### Does it change the appearance of the stone?
It is described as clear with a matt finish, and the listing claims it leaves a natural appearance. Customer feedback on appearance is mixed.
