What sealer to use for edge of Porcelain tiles?

[Rockingmark]

I have just fitted 300 x 600 x 10 glazed porcelain tiles with straight cut (unglazed) edges into my ensuite. The room has a window sill, which I have tiled with the same tiles. Hence the tile edges are on show. We didnt like the idea of using tile edging strips to finish the edges, as nothing suited our tile. So as the tile had a straight cut edge I decided I preferred it to be on show. I found that if I wet the edge of the tile it darkens the cut porcelain and masks the machining marks in the edge of the tile. This is the perfect effect I am after. Of course this isn't a permanent effect as the edge dries and so will need sealer for a more permanenet affect. Please can someone recommend a sealer that will create the affect I want i.e. darken the porcelain, mask the machine marks and not have a 'varnished look'. There are so many surface sealers out there and I am sure some will darken the tile edge and others will not.


I have considered LTP colour intensifier and stain block. Would this be suitable? Any one used this? Is it a good sealer.

Many thanks in advance for any advise given.

Intensifier is designed to impregnate. What you need is something topical.

I'd probably try Lithofin Slate Seal.

Dress the edges with diamond pads.

Diamond pads would smooth them but not give the gloss sheen the OP is looking for.

I would try wet and dry on the finished edge 600 followed by 1000 grade wet, then apply a sealer to give it a finish. Worth a try ?
