Last year got Tobermore Historic flags (bracken brown colour) laid and jointed. 'Paver' decided to use Ultrascape Flowpoint and ended up permanently staining all the flags grey (believe area was either not pre-soaked enough or product not washed off enough), anyhow... thankfully he laid all new flags (same colour) but he would not joint it. Therefore I would like advice on what to use to joint it. Ideally I would have liked to use Larsens streetscape GPM but having tried this in a small area the joints aren't wide enough even with small gun nozzle to get the product right down into the joints. And am nervous to try the FJM version based on last years disastrous experience :(
Area is just over 40 sq m.
I have dogs and will need to be able to hose the area frequently.

What options do I have?

- Would traditional style of brushing in a sand and cement mixture and then wetting it work?
- Or are 'slurry' style products such as Rompox D1 my only option?
- Slightly anxious about anything the slabs being left 'grey' or permanently stained and from what i have heard Rompox Easy which Tobermore recommend would not be durable at all

All advice greatly appreciated, just want to be able to use my patio :(

What are the joint widths?

The smallest are around 10mm at top and then I'd say widest is around 15mm. They have those spacing type bumps on lower half of each side which touch on most flags.

If you have 10-15mm joints use a good polymeric. I use weatherpoint 365.
Easy to use and no permanent staining.

I have jointed these with fjm with no problems but you need to be vigilant.

Have they been laid on mortar? Tobermore market these as being laid on said and jointed with dry sand but must be laid on mortar if your want a pointed joint to last.

I lay them slightly spaced as the standard joint made by the spacers is too small.

The wavey edge means you can't use a gun product so you have to use a slurry.

I would use rompox D1 if you dont want to go with fjm. Here in N.I you will struggle to get anything other than Rompox D1 or fjm. Weatherpoint GTFK etc are not stock or supplied here to my knowledge.

Thanks.

They are laid on sand. Do you know cost/stockists of rompox D1? Is it durable for say 5-10 years?
I saw video of usage on you tube - is it that simple that you keep wetting it till job is done?

If they are laid on sand the pointing will not last very well as there will be a tiny bit of movement rather than a rigid mortar base.

Last time i used it D1 was 41 plus vat. It was available from mcnaughton blair but they have stopped using mcmonagles who supplied it as far as i know. try them or if not tobermore can supply it. failing that mcmonagles may supply it directly.

Due to the longevity being suspect as the flags are on a flexible bedding i would perhaps try and make a mortar slurry yourself from sand and cement. 4:1 plastering sand to cement and pour it in with a watering can.
Scrape off the excess and keep it lightly misted and brush it a little to remove the cement from the faces of the slabs. Once its firmed up after a few hours hose the whole lot down.

It may require some trial and error but will cost nothing compared to D1 which may cost you a few of hundred

Apologies for my ignorance in these matters, but with compacted stones etc beneath the sand - you would still class this as flexible bedding?

Yes its flexible bedding so isn't suitable for a rigid joint.
kind dried sand is needed.

You can get the Romex D1 straight from Tobermore or from the wee Donegal man, Davy, on +353 86 040 0084

Weather here is a nightmare and Tobermore now charging over £60 +VAT for D1 and alas I am very far from Donegal. Has anyone ever used 'Drive Alive' brush in resin and would they recommend it?
