Indian black limestone advice needed - Sealing problem

[Canvas]

I contracted a landscaper to remove by old patio and grass front and back, replace with decorative Indian Black Limestone and artificial grass front and back.

The job seemed to go well and on-time upto the point of sealing, the only problems were a stripe effect on the front grass which I was told it was because of how it had beem rolled up and would disappear as the blades rise, and a cracked flag that was subsequently replaced after original sealing.

The landscaper advised these should be sealed for protection and to give a wet glossy look which would last around 2 years at an additional cost of £300. I paid just under £10K for the work , half at commencement and half when everything was done aprt from the sealing, just witholding the £300 for the sealing. Everything was good upto the sealing.

These were left to thouroughly dry out for several weeks during the hot summer last year then they were cleaned and sealed. This is where the nightmare started, after the first rain the flags became stained with white patches.

The landscaper said the sealant had failed and said he would sort it out, he came with a substance he applied all over the flags and left overnight, he took the back artificial lawn up as he said the substance would damage it, after this removal it looked absolutely terrible with white stains etched around the edges and looking generally awful. It also aged the resin based grout. The subsurface of the grass was disturbed during power washing and the grass looked a bit stretched and crumpled in parts when relaid and looked like some sub surface had been washed away as it seemed to have sunk a bit.
The landscaper blamed the sealant supplier and said he would call him in, he did this but the resin supplier said he had never supplied any remover but agreed with the landscaper to try to recover the flags, he applied what he said was a mild vinegar like acid to remove the failed sealer completely then washed it, he said had this been used there was no need to lift the grass , he cleaned left for several days to dry and resealed but at the first rainfall the exact same problem happened again.
They are now both blaming each other and neither are prepared to do anything about it, they have left me with a horrible looking patio, grass that is not perfect like it was and £10K out of pocket.

Any advice on how I should sort this? Who is responsible and are the flags recovarable.

I want to attach photos but am not sure how.

Hi Canvas

This was the original sealant

Yet again people using the wrong product for Natural stone, that I'm afraid is a full strip of that rubbish sealer, then the paving cleaned up, and then a colour enhancing impregnating sealer applied.

Thank you for your reply, I have a few questions

1. Which product / method would you recommend to strip this?

2. Will any stripper damage the artificial turf?.

3. Which sealer / colour enhancer would you recommend?

Thanks in advance

[RAPressureWashing]

Doing a strip like this is not really something I'd recommend to a home-owner, as you need to use a chemical which has to sit on the surface for at least 6-8 hours and steam/high heat, plus you really need to know how to use these correctly which I can't teach you via a web-site forum

To answer the other questions,
No the stripper shouldn't damage the artificial turf, but care is needed when doing this sort of work

As for sealer, my choice would be Miracle 511 enhance & seal, a colour enhancing impregnating sealer.

Thank you

Which chemical is the stripper?
I am not going to attempt it myself, not my field but I want to ensure who does do it is doing the correct thing and not repeating the nightmare.
I am in Lancashire so you are not in my area and I do not personally know any specialists in this field.
I am hoping the original landscaper will put this right by bringing an expert in , if not I think I have a good case to take this to court.

[RAPressureWashing]

Where in Lancashire ? as I do know some companies up that way that could do this, how big an area of paving do you have?

Not far from Wigan, have about 50 sq metres

I am unable to help you with the issues on this post, I think R&A are best placed for this. That said I am concerned about this particular logo/branding which I have not hitherto seen. As a consequence, I shall be contacting our IP lawyers today to see if there is a case for Passing Off. For the avoidance of doubt this product has no connection with Resiblock Limited.

ResiPly is John Stafford's business up in Standish, on the outskirts of Wigan, Craig. Their main product is a jointing mortar but they've also got these acrylic sealants which they've been pushing hard for the last 18 months or so as the public become even more obsessed with the belief that every square millimetre of every possible type of paving has to be sealed otherwise the sky will fall in.

As Roger from R&A identified, this is a less-than-ideal product for this type of paving, and it's been inexpertly applied. These cheaper acrylics may have their uses on some types of very porous sandstones or even some budget-end concrete wet cast products, but I'd be reluctant to use them with denser stones, such as limestone, granite or slate.
