I have a shower where some grout has fallen out at the corners, where the walls meet the floor. I went to home depot and they sell a few types of sanded grout (the gaps are 1/8" or more).
I saw a brand named "fusion pro" which does not require any sealer, so it's just one application. Has anyone used this kind? link Or would you recommend sticking with more traditional types?
And lastly, can anyone recommend how to get the grout into these corners? All the videos I've watched are on the flat wall faces and use a float.
