Questions about installing bullnose baseboard tiles for bathroom
1. Which notch and shape trowel should I use? I'm assuming a 1/4" v-notch. The bullnose tile is 3" high and approximately a 1/3" thick.
2. The floor has 3/16" groutlines. I want to use the same width for the groutline between the bullnose and floor, and then fill it with grout. I'm reading that many people recommend making the width smaller and the filling it with chalk instead because this is a bathroom. Is that effectively necessary?
2. I'd go an 1/8" max, but whatever you want is fine if you think it'l look ok. Usually wider joints are for rustic tiles. So, I say 1/8" or less, maybe use pieces of the cardboard the tiles came in. It's best to use a matching caulk at that joint cuz grout is likely to crack.
