Ran the pressure washer over the patio today. No idea how long it's
been there but quite a while and it clearly hasn't ever been washed
before. Pressure washing might have been a bit over-vigourous as some
of the aggregate is showing but I've no way of knowing whether they were
always like that.
The colour wasn't really visible before (just dirty grey) but now
they're buff when they're wet and closer to light grey when they're dry.
The buff colour looks better so I was thinking a coat of patio sealer
might help bring the colour out and stop it getting quite so grubby in a
hurry.
The paving expert site seems to quote PU as the best formulation,
whereas the 'normal' stuff is acrylic. Not cheap (about a fiver per sq
m for the Cementone stuff at my BM), so I was wondering if anyone has
used it on concrete slabs and whether it did a decent job.

Cheers

I used a solvent based sealer. Stank the neighbourhood out for a couple
of days and achieved precisely bugger all

I've used solvent based and water based several times, neither of them
lasted longer than a few months

Ineptocracy

(in-ep-toc-ra-cy) €“ a system of government where the least capable to
lead are elected by the least capable of producing, and where the
members of society least likely to sustain themselves or succeed, are
rewarded with goods and services paid for by the confiscated wealth of a
diminishing number of producers.
