Hi really hope you can help for after suffering 4 months of ongoing trouble with the paving of my 70sqft garden, I’m at my wits end.

I invested in some gorgeous pale grey, 20mm porcelain slabs. It soon became clear that the landscaping company I employed have never laid porcelain slabs before, and so began the trouble. I’m faced with an ok job, but the worst part is the awful patchy resin stains left behind on the slabs as a result of the brush in dry resin mortar they used. Is there anything that can be done to remove it?
Ps I’d attach a photo, but can’t understand why you just can’t attach an image rather that creating a URL link.

Please help. It’s been a lot of money, I’m totally disappointed with the job done and just don’t know what to do next!

You can't "just attach an image" because that method is much beloved by spammers and porn-merchants. I don't want that on my site.

In theory, porcelain is not supposed to be stain-able and resin mortars are not supposed to leave a stain but.....there is some worryingly shoddy porcelain coming onto the market lately, and some of the not-particularly-good one-part resin mortars are using cheap doping oils, such as Rape, to defer curing of the mortar.

I don't know what was used on your project. If it is because of cheap porcelain and an indifferent resin mortar, then there is a good chance the oil will gradually decompose, but in the current low temps, that might not happen until next spring. If it's a really cheap porcelain and a shockingly poor resin mortar, it could take much longer than that.

If you want to try expediting the process (and that might be tricky and less than amazing at this time of year) then a good quality oil remover, such as Resiblock OR, OT8 or similar *may* help improve the appearance.
