Grouting advice for artificial joints. - Tile Advice

[Drifterjoe]

I guys laying the tiles below this week. Is there a technique to grouting the artificial joints?

They aren't very deep so do I need to let the grout set a bit longer than normal before washing down?

Yes you are right, flush up joints with grout and leave to set longer than normal. Wash off excess grout with sponge but wring out well as don't want too much water. Some of the guys on here use damp micro cloths instead of sponges so you could try that aswell

Some of these tiles have glazed joints in which case it's virtually impossible to get grout to stay in, run the grinder blade down them slightly if that helps

Thanks guys.

as above with both suggestions. I've run the bridge saw over the joints in the past just to get a half decent depth and/or remove any pooled glaze.

These tiles are stupid idea, why they don't make them 200x200 is beyond me, the pre scored joint is too small anyway (less then 2mm so you can't make the normal joints the same size on floors) It is almost impossible to grout them up without it pulling out so you just have to be patient and keep going over the bits they do. Tip: I am installing similar to this in my bathroom but have pre cut them all on the score line using the Sigma so that I can create even joints at the right size and get the grout in the joint. They cut really easy, no scoring required.

Seems like they could be a pain in the ***. Laying them tomorrow. I'm not keen on the idea of running the grinder over them as I'm in a bit of a rush to get it done.

What about if I try and convince them to go for terracotta grout?? If the colour is a close match.

How did it go? What did you go for?

They were quite tricky in the end. Basically the grout lines are too thin for even my thinnest grinder blade so would just have chipped the glaze.

I layed them as they were and had to use 1mm spacers adjusting by eye as the joints are too wide with a 2mm spacer.

The grout went on ok but did wipe out in a couple of places. Going back today to silocone the shower so will have a go at touching up the areas that are showing through.

I explained the situation to the customer and they were fine with it.

Take a couple of snaps for us.

A bit late now..

sorry, sorry,
but I thought it was a normal thing.
Instead, I reread the trend, and no, it was not normal.

yes @JulianSidney is old ....
because, cut the lines with grinder, what is?
Perhaps primitive ?
