Patio Tile Grout

dave23

We had a porcelain tiled patio laid about two years ago, dark grey tiles with white grout. Some areas are of the grout now need replacing, what sort of grout do I need to buy?

You might find this type will shrink/ crack due to the varying weather conditions we have . And the large gaps in paving unlike tiles

Apologise apologies for slight hijack. We have a couple of fairly large stone slab patios & paths and the grout/mortar? is crumbling. 

Can we simply remove the loose bits & replace with the Sika Paving compound, or will it all need removing?

How big are the joints?

it will look patchy and you typically find that if some areas have started to fail then the rest will start to follow shortly thereafter and you'll be constantly patching.  The recent developments in brush in (some are just hose down)  compounds will save many a knee as manual pointing was awful (though therapeutic!) but ideally you want to rake out all the joints and repoint them all in one hit.

It has cracked and crumbled in places, I will measure the gap tomorrow

Thanks. I thought that might be the answer. Not sure if our 70+ year old knees are up to it.

The gap is 5mm
