I recently had a two day bathroom repair job in York town center. The apartment had two bathrooms and the grouting in the bathrooms started to look yellow (ish) and tired. The owner tried bleaching it, steam clean it but didn’t work. The only solution is to take out the old grout and re-grout the tiles after that.
I mainly used two tools for the removal of the old grout. One was a Bosch Professional multitool with the proper grout removing blade. It works well around delicate areas, but makes lots of noise and dust so full PPE is required. The other is a £4 hand grout rake. I bought two of it just in case it goes blunt but even after two bathrooms it didn’t show any signs of wear. The only downside of it that after using this rake for about an hour your arms will fall off. It’s safe to say it is very hard work.
So after what it felt like an eternity, I had the old grout out from between the tiles. I then used a paintbrush to remove every speck of dust to make sure the surfaces are as clean as possible. The second part is relatively straight forward. Mix some grout and section by section you fill in the joints using a grouting tool and use a sponge to clean off the excess. Timing is crucial as if you wipe the tiles too early you smear the grout, if you try to do it too late it will set rock hard on the tile.
All in all, it took me two days to remove the grout around a bathtub and in a shower cubicle and then fill it back in. Hard labour, but the result speaks for itself. Another happy client and I was away for my next project.
Screw it!
