Grouting Between Paving Slabs

[douglas9401]

They're old but in one piece and currently have sand brushed into any gaps but I'm wondering if I can remove the sand and brush in Postcrete as a no-fuss, more solid filler, just mist with some water and the job will be done.

Or will it?

Ta.

The trouble with concrete, Dougie, is the chippings in it. They're only small in Postcrete, but they will tend to stick out as you try to brush a smooth finish.

Ready-Mixed mortar would be easier (sand & cement.)

Get some "Joint-It".
It sets rock hard and doesn't crack as easily as traditional mortar. You brush it in dry, so you don't even need to mix it with water, etc - dead easy to do.
I repointed my top patio about 10 years ago and it still hasn't cracked.

Here's a link to one that I bought a while ago ..... it's out of stock, but you can have a look at the description, etc:

^^^^^^
Looks like it's back in stock now :)

Never occurred to me that it would have 'bits' in, though it really should have.

I'll try the premix mortar first and spend the balance saved on beer.

Thanks both. :-)

Sand is fine, why make another impermeable area the rain can't soak through?
You don't say what is the problem.

[douglas9401]

The majority of the area is to grass, Khandro, no shortage of soakaway at all, I just want fewer weeds and a smoother transition between slabs.

It's not a lot to ask at my great age. ;-)

[Gizmonster]

I still reckon that the "Joint-It" in my link is far better than traditional mortar.
It will last a lot longer and it's a lot easier to apply .... no need to mix with water, just brush it in straight out of the packet. The only downside is it's quite expensive, but it's worth it in my opinion.

[douglas9401]

If the mortar doesn't work out I'll certainly give that stuff another look, Gizmonster, thanks.

I take your point douglas, it sounds as if it will make little difference, it's just that councils are trying to encourage people not to seal everything over in order to ease the pressure on the drains, particularly during storms.
