Our builder laid fabulous black 1200 x 600 tiles around our house and also on a large patio.
He used Fast Point brush in grout and it looked great for a while.
Unfortunately, the grout is all falling out and we have never been able to powerwash by any means as the grout comes out too.
I notice that the depth of the 12mm gap between the tiles is sometimes only about 5mm, so I can see why perhaps this is happening.
I'd obviously like to fix it.
I can see 2 possible solutions and I am really hoping that the first will work (my reason for posting).
1. I am thinking of powerwashing the old grout out. I now this will be fairly easy. I could then use different grout.
Would this work? Is there enough depth for grout to hold? What grout is recommended? Will it bond with the tile cement?
Otherwise:
2. I use a carefully aligned track saw with a diamond blade and cut out the fixing cement to a greater depth and replace the grout (again what would be best)?
This sounds like a lot of work as I have about 75 square metres of tiles and I hope to avoid this.
Or is there another way?
On a separate note - I see he has not put in anything to deal with expansion and the black tiles do get hot! I have had one crack so I guess this must be why. I am guessing I need to consider this if I can replace the grout.
Any advice here would be really appreciated.
Thanks
