I've been fitting a lot more square edged porcelain tiles recently & struggling to get a neat grout joint.
Traditional ceramic tiles usually have a lot of suction & the grout stiffens up quickly, allowing it to be smoothed to a good finish with the sponge.
Porcelain tiles have little or no suction & the grout stays soft for hours so the sponge frequently lifts too much grout out of the (usually 2mm) gap. I use a much stiffer grout mix for Porcelain to alleviate this but has limited effect.
What is the best solution? I'd like the grout to be flush with the tile surface
Should I deliberately over sponge the grout, wait for it to set, then put a 2nd coat on, using the suction from the first application to aid final dressing? I tried this in a small area, the results were goid but I don't like the idea of having to grout twice.
