    Default Sealing Tiles, before or after grouting

    As per my earlier post I have discovered that polished porcelain tiles are very porous. In light of this I will have to seal them. Some questions:

    1. Should they by sealed before the tiler grouts them?
    2. If not, won't the tiles absorb some of the grout thereby ruining the entire job?
    3. What sealer should I use? Is there really a 'apply once only' sealer available?
    4. Will the sealer affect the colour and polish of the tile?

    Thanks in advance
    Tony

    I have polished porcelain tiles in my newly renovated bathroom. The tiler grouted all walls and the floor and left the sealing of the tiles up to me.

    I guess when you think about it, what harm will the sealer do to the grout? If it discolours it (which it shouldn't) you can always just re-grout.

    Hi Flashman,
    I'm also just a DIYer but my understanding is that you would seal both tiles & grout at the same time. When your tiler grouts, the excess is wiped off with a damp sponge. Why are you concerned that you have to seal? I would have thought that sealing is part of the tiling job that you engaged the tiler to do.
    Cheers

    I'm worried that just like the tiles absorbed a marker pen which is not removeable (see my other post) that they may absorb some of the grout when wet and get discoloured....

    Anyone recommend a good sealer? preferably a 'apply once' product...
