Final question on my hearth - sealer

I've built a hearth out of pammets exactly like these:

A stove will be going on top. My tiles are very porous, having been acid cleaned. Can anyone recommend a matt sealer for the tiles?

thanks

I used LTP Colour Intensifier and Stain Block on my black limestone hearth and am really pleased with the result. Blocks all stains and beads any water spilled on it. Also gives a nice deep finish to the colour.

You can get it at Tile Giant.
