Can I add more grout on top of existing grout?
+5
Hi All! Last year, I had tile floors laid in a bathroom and laundry room and it looks great...EXCEPT there are places where the grout was not left thick enough and some of the thinset is coming through. The guy who did the work was supposed to come back and take care of it but never did and I cannot afford to pay someone else. I have a good bit of the grout left over and am confident I was wondering if I can just do another layer of grout over what's existing to make it thicker or if I need to remove the existing grout before adding more. Thanks for your help!

Hello @Tami! I just wanted to say that I am sad you got shammed by an unreliable contractor. I have been working for a Melbourne-base cleaning company and we do tile and grout cleaning as well as regrouting. Over the years I learnt that when it comes to renewing grout, it is always best to remove the old remains before you lay new ones. From what you's written, I believe that your contractor did a lousy job and didn't even sealed the grout. I hope you will succeed in your DIY project! P.S. if you have it in your budget, seal the grout with a high-quality product. In the long-term it will pay off :)

Tami- I had to do this recently to brother's bathroom. I use a flathead screwdriver to remove any loose grout and scratched what stayed. I then over-grouted the whole bathroom so the colors matched. Then I sealed it all again. Took 2 days as you need to wait for it to completely dry before sealing. Hope this helps. ps- Hubby was very impressed with what I did and he has done home improvement for near 45 years

There is a tool called a "grout saw" it is basically a thin metal blade that has a diamond or carbide aggregate applied to the "work surface" You use it like most "saws" with a back and forth motion. It will dig out the old grout and high spots of thin set...once that is done you can re-grout. http://www.homedepot.com/p/QEP-Professional-Hand-Held-Carbide-Grout-Saw-10012Q/100001353#.Ujna-dK-rmQ

I saw where you can use what looks like a pastry bag filled with your grout, and pipe the grout into the space between the tiles. Then go over it with the float making sure you are pushing the grout in. Sees that this would make sure that you are not missing some spaces.
