LTP Mattstone
Second Coat Application
After 1 week
Result after 1 week (Mid-September 2015)
March 2016
Result after 10 months (March 2016)
September 2016
Result after 14 months - end of trial - September 2016



1st coat: Very thin, clear, petrol-like liquid, easily splashed. Rapidly absorbed

2nd coat: +1:22 hrs Slight foaming, but good coverage rate. Smell of floor polish


Another LTP product that's barely detectable, but unlike the LTP Natural Finish this one can still be seen at the end of the trial, as long as you look carefully.

It's fair enough to say it's a matt finish. There's definitely no sheen or gloss, and the only real way to tell it's there is to spot the slight difference between the treated and untreated parts, most noticeably the line of difference towards the right-hand side.

Judging from the Spring 2016 stage photo, it would be hard to say the coating had managed to fend off the algae, but come September, at the end of the trial and after a summer in the sunshine, not a trace of algae to be seen. Strange!

But is a practically undetectable sealant what's required? Is that enough?

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


Very poor result. All four main stains still on show and the mosskiller has left its mark, too.

As with the LTP Natural Finish , the name doesn't suggest stain protection, and it certainly doesn't deliver, it's sad to report.

Unfortunately, there doesn't seem to be anything positive to say about this candidate.

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.
