Removing adhesive (I think) from patio

zig

Hi, we got a patio done about 3 months ago. The tiles are a white or slight off white colour. Anyway the guy that did it seems to have left what seems like a layer of glue on the top, I mean all over the patio.

I wouldn’t have even known it was glue only it was sticky on the day or two after he finished.

The thing is it seems to have had stains under it since day one which we can’t budge. I’m convinced there’s a layer blocking the stains because some of his boot footprints are underneath and also some red chalk marks where he’d been marking things.

Is this normal and is there anything that can budge it?

Dont get me wrong it is possible with about 2 hours work to remove about 5cm squared but also I’m terrified of destroying the tiles in the process.

Not sure if something like this might work https://www.did.ie/products/ceramic-hob-scraper-152949 I use them for a lot of surfaces including glass with no issues if used at the correct angle. You could use an alcohol type solution with it.

Sounds like he used a sealer on the tiles but pictures would help.

So Im not sure its obvious to someone who doesnt know the original patio colour, but basically when looking at it, when you see a contrast between the white and more yellowish or dirty colour, the white is what the original colour is, we have 2 tiles left over that we're put down and that they look like the white you see in the pics.

Cheers! I'll check this, Im worried the layer might be so thin that this wouldnt be able to reach it, but it could work 👍️

This happens a lot when using a brush in compound like joint it. You are supposed to wet the slabs first, brush in the compound and then wash the slabs down with water to wash away any remaining adhesive. It will be difficult to remove now but I think some of the brush in compound manufactures provide a removal solution.

I decided to use sandpaper, not sure if that is a big no no or not but it’s working. In fact the difference now is so ridiculously obvious it’s even easy to take a photo. It’s not too hard to scrub either. Doesn’t roll off but i see it visibly coming off fairly quickly as I scrub.
