How do I grout my outdoor Brazilian slate pavers?

I have purchased the Brazilian slate calibrated slabs and still need to purchase the grout.

I have been advised by your office to use the Granfix Maxi Tile Grout Flexible.

Is this applied after sealing the slabs and is this grout applied with a float the same way as you show for Brazilian tiles.

Hello Victor

It is advisable to seal the tiles before grouting and then again after, this initial coat offers protection to the stone and ensures the removal of the grout residue is much easier.

The grout can then be applied in the same manner as you would indoors, using a float.
