I HAVE A BIG PROBLEM WITH THE PORCELAIN PATIO THAT I BUILT

A year after building my porcelain patio, the grout started failing in a few places right outside the front door. So I had to find out whether I could repair it without completely wrecking the porcelain tiles. In this video, I try three ways to remove the old grout: a cheap grout rake, an oscillating multi-tool and an angle grinder. I then regrout the damaged lines, clean the porcelain paving and check the DIY patio repair after 24 hours. I’m not a professional and this is not expert advice or a tutorial. It’s simply me trying to fix my own patio, learning as I go and documenting the result.
