My 1st Job Chips pre-grout. - Tile Advice

[redchair]

Hey again. All tiling done and just about to grout shower when I’ve noticed I’ve got 3 tiles with small chips on the edges. My immediate concern was the grout colour bleeding, I’m using natural grey 3000. But I’m now more concerned of the tiles absorbing water.
Can I out a simple sealer on there or glue to waterproof? I’m not too concerned about the look, my family was pretty excited about me finishing the bathroom tomorrow so I just want it done.
How would you guys/gals deal with it?

Change the tiles.

Morning Andy.

Would love for it to be that easy, but I've no tiles remaining (I'm a novice!) and removing any tiles will remove the backer board, I've zero doubt!

I've looked at the Cramer products and may give them a go. Any experience using them?

Neither of the chips are especially noticeable, I just want them sealed properly.

What would you do if replacing wasn't an option?

Thanks man
