Hi,

We have a courtyard garden that has been pathed with tiled rather badly.

A couple of questions:
1. How can I clean the slabs so they all look neat, tidy and the same colour? Currently they are marked and look dirty.
2. How can I relay loose ones? 3:1 sharp sand and cement and the back butter them to lay them down?
3. When do you grout in between the tiles with?

Here it is:

I've also managed to find the barcode on one of the slabs and with a bit of searching the internet I've have found that it's these:

Hope that helps,

Thanks for your time and help

Hi Chris

1. You should clean the slabs with hot soapy water and a stiff broom :;): Only joking a jetwash will bring them back as good as new.

2. When laying the slabs back down use a 5 -1 mix of sharp sand and cement semi dry. No need to butter the backs of the slabs

3. for pointing use a 4-1 mix of building sand semi dry

All the info is on the main site

To expand on what Steve said, if any slabs on a free edge are loose make the mix a bit wetter and or add some SBR to it to aid adhesion.

Thanks for that advice guys.

Can you just clarify what Carberry means by:

1. Slabs that are on a free edge?
2. Add in some SBR?
3. Is this on the bed I lay to place the slabs or is it the joints you mean?

I'm a bit unsure what you mean.

Thanks
