Sealant Trials - Romex Colour Enhancer

After 1 week — Result after 1 week (Mid-September 2015)

Result after 14 months - end of trial - September 2016

Summary:

Application:

1st coat: Medium viscosity, clear resin. Doesnt spread much without aid

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

Comments:

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

Comments:

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.
