    Aghhh! .. I should not have left leaked the oven cleaning liquid on top of my new granite top (I think its' what it's called).

    Now big area of the surface is damaged like this http://prnt.sc/f5y42w and I have tried http://www.wickes.co.uk/Ltp-Mpg-Sealer-for-Polished-Surfaces-1L/p/119832 which doesn't even help tiny bit restoring the glossy top layer.

    By the look of undamaged area and comparing with damaged area, some kind of clear coat was applied on stone surface before which has been eroded away by oven cleaning liquid. So I was wondering where I could buy that top protective coating again to repair damaged area.

    Any advice and tips will be massively appreciated.

    First thing to do would be to get in touch with the worktop manufacturer and explain your issue. Unfortunately it appears you may need to strip the rest of the top then recoat it with the finished glaze. But before you panic, email the manufacturer.

    Agree with Jord, that worktop will need stripping back & a complete refinish, buffing, polishing & resealing, a job better left to the professional, definitely not a diy job,do you have accidental cover on house insurance.

    Must a specialist granite finishing specialist in your area.

    Agree with the two previous posts, also if push comes to shove you could ask a Monumental Stonemasons advice. :)

    For heaven's sake.
    Get yourself some 2000, 3000, 5000 and 12000 grit aluminium oxide wet and dry sanding/polishing sheets.

    Agree with Handyandy, get a set of these, I got some to polish the edges of granite tiles, worked a treat. Lot of elbow grease required but did the job.

  7. It's a new top - ask the manufacturers before you resort to abrasives.

    You describe it as 'granite' - but we don't know what actual material it is.

    Good chance it's totally fixable, tho'.

    Better to leave it to professional firm to do the work, it's a lot of expense for buffing discs,cleaner, etc.

    No accidential damage cover on house insurance.

    It's very difficult to sand a "patch" on a worktop as 9/10 times it will always show, and sanding a few edges it very different to sanding an entire face of a worktop to stop it looking patchy/ stripy.
    If you have the cut out from the sink have a go at that first if you really wanna try yourself,but the pads and polishing compounds used on granite tops are rather expensive so like kiab and DA say, it makes guy be better to get your original supplier to come have a look or maybe try somebody like magicman or your local equivalent

    Did you manage to get this sorted. Exact same thing happened to me this week. Your help would be appreciated. Thanks

    I’ve done the exact same thing this weekend. Looking at a way to fix it. I’m going to ring the manufacturer for advice tomorrow. Don’t suppose you found a way to fix it before I call?

    Been advised by suppliers that the only option would be to replace as nothing can be done to fix it. I have been in touch with a firm called The Plastic Surgeon and forwarded them photos of the damage. Awaiting to hear from them if it can be repaired successfully
