1st coat: Medium viscosity, clear resin. Doesn’t spread much without aid

2nd coat: +1:22 hrs Slight foaming, good cover, resinous odour


This product seemed to lose at least half of its impact over the winter, and then whatever was left, wandered off over the summer, so that, by September, it was undetectable.

Maybe the slightly pinky tones of this particular piece of stone are 'enhanced', ever-so-slightly, but it's nowhere near as strong as would be expected from a products selling itself as an 'enhancer'.

For a product that did so well with the Black Limestone trials of 2011, it's obvious the impact on more porous stone is much reduced.

Stain Trials:

stain application
Application of stains
stain after 4 hrs
Stains after 4 hours
wash off stain
Wash off stain with proprietary cleaner after 24 hrs
apply mosskiller
Apply mosskiller after wash-off
stain after cleaning
Stain 48 hrs after washing-off mosskiller and cleaning with proprietary cleaner


Is it the porosity of the sandstone that's affected this product so much? The colour wasn't really enhanced, and the stains have not been repelled. yet this very same product worked so well with the black limestone and, perhaps naively, great things were expected from it once again.

The best that can be said is that the mosskiller has clearly affected the untreated area far more than the treated, which is a positive, but the BBQ fat in particular has been allowed free rein.

Note: Any apparent variation in colour of the flagstone is due solely to changes in the condition of the natural daylight at the time the photograph was taken.

Other than cropping to exclude extraneous background and adding a drop shadow to the cropped image, there has been NO post-processing of the original photographs.
