Ultra Tile ProGrout in wet shower walls

john2k · 2026-06-06T14:18:51+0100

I’ve recently finished my bathroom rebuild and grouted the floor and walls with the progrout pictured below. This includes inside the shower area. The corners are siliconed with sanitary silicone. My question is do I need to seal these grout lines specially the ones inside the shower area that get water running down the wall on them?

If so what do you seal them with?

Thanks
