1st coat: Thin liquid, heavy foaming, apply with excess and leave. Dries very quickly

2nd coat: Less than +10mins. Very foamy, surface dry in under 5 minutes


There was some suspicion that this sample was accidentally contaminated with water straight after the application of the first coat, and, because the possible impact of a drenching before the sealant had a rea; chance to cure, it was decided to prepare a second sample, which can be seen here .

On this sample, if you squint and concentrate hard, it's just about possible to detect where the sealant was applied, but only just.

This piece of treated stone does seem to have kept itself cleaner than some of the other samples so maybe it has to be counted as a success.

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


Perhaps the accidental spraying with water before the first coat had a chance to cure *has* affected this sample, but stain-proof it is not!

Every one of the four main stains has left its mark, some worse than others, and even the mosskiller has put down a mark. The minor side sopklashes of wine have also marked the stone, so this can only be regarded as a fail.

Maybe the second sample will have fared better? Let's see.

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.
