The dreaded black limestone - Is slurry grout a viable option?

[Quaife Landscapes]

Hi All,

We have a fairly large Black Limestone Patio coming up,
And I'm wondering if anyone has slurry pointed black limestone with the aid of a pergo machine?

I've used this technique a few times on sandstone and cobbles/setts but I've heard so many nightmare stories on limestone I thought I'd check with the experience in here before making my decision.

Thanks

Anyone?

Lay it, clean it, seal it, then slurry it.
Pergo may be a bit overkill and will still leave residue, a good squeegee and plenty water will be grand.

Did you actually go ahead with the Pergo?

The success or otherwise of using these machines seems to be dependent on the degree of riven-ness. Some heavily riven flagstones just don't clean well with a belt machine - too much grout remains in the nicks and hollows - but I;d guess that the black limestone, being typically only lightly riven, should clean up better than some other types.
