I have just completed 30m2 of Stonemarket Travertine on a patio in the garden, and am curious to know should i seal it or not? Also whether to use a Travertine sealer or something like Resiblock. Its the first time as a company that we have used Travertine (thought id try it out at home first) and i cannot find any relevant information concerning external Travertine.
Any thoughts chaps
