Moss between the patio blocks (again)

[Burnerman]

Gawd, not again!
As per the title, but has anyone tried the two tubes in one resin adhesive applied in the cracks with a silicone gun, or is that a loony idea?
I have to pressure wash mine twice a year, and the kiln dried sand is long gone.
Have a good evening, everyone

You have block paved patio or a slab/flagstone patio? Please clarify

 

[Burnerman]

Block paved, blocks maybe 6" x 8" laid with no appreciable gap.
Thanks for your reply!

Use a tried and trusted brand moss killer, if it bothers you so much.
Personally, i like to see moss colouring in the edges of a block paving...and yes, squirting silicon between the gaps is a loony tune.

I use Patio Magic solution, reasonably effective but I want to make things as easy as possible for me.
Parts of the patio are in shade and the moss / algae or whatever and it looks awful.
I didn't mention using silicone at all, rather a resin bonding adhesive which I'd imagine is polyester based. I'd inject a very thin bead of resin over the joins.
What's so loony about that?

Injecting silicon in the gaps would affect water run-off from the drive, would it not?

 

[Burnerman]

Happily, the water doesn't pool anywhere, but gradually drains onto the lawn so no issues there.
It's just the moss and weeds I want to lose.

Epoxy resin will make a big mess
Get a wire brush and just brush the joints regularly, followed by a normal broom.

Many don't realise but a simple built-up of detritus in the joints lead to the perfect conditions for moss. Remove this every couple weeks and it will stay a lot cleaner

OK, thanks for your input!
I may give the resin a chance using a very fine nozzle but it will be in an area where it can't do any harm.
