Hi Andy, welcome to the forums. Can you tell us the type of porcelain , polished porce is the only one that requires sealing.Adhesive needs to be flexi or have porcelbond for it to stick,and grout needs GT1 additive added for it to stick to the sides when grouting. Grout wise i suggest this stuff.....Gaz

10mm is required for this big tile, you must use an impregnator sealer suitable for polished porcelain..I rate the Fila one but see what is available in your local merchant....Gaz:yes:

Tiling onto SLC should be fine after 24 hours.

Agreed. Sometimes quicker, depending on the type/ manufacturer.
