Hi,
Got new patio finished on Wednesday. It's indian sandstone. The contractor used easy joint for the grouting. I noticed when he put it on the first section to have a look at it that the slabs were all bone dry. They'd just brushed it in and packed it down. It looked ok, and I didn't have a clue what was right/wrong method to put this type of grout on was. They've finished the whole lot and now three days later I'm noticing dark stains along the edges of a lot of the slabs. Not all of them, but on some slabs where one edge is not against the easy joint, ie the fence, it's totally fine and no stains, the other three sides that touch the grouting do have these marks. So to me it looks like it's the easy joint that's causing it
I've read up about easy joint and see there are two methods to apply, wet and dry. The dry methods requires sealing the slabs prior to brushing in the easy joint. I know for a fact this wasn't done.
Does anyone know what I'm looking at here. Is this 'picture framing' going to get worse and worse and permanent. Is it a bodge job done by the contractor?
I've read through the, very useful , forum topics and seen some posts about doping oil blooming/picture framing slabs. Is this likely what's happening here? Or is it too early to know as the patio just been laid a few days ago?
I've tried adding added a couple of images, but seems impossible to upload them using this forum board. They might work. Or I might have to stick them to a tenner and post them to the site moderator!
