You will see a thick wallpaper line between the sheets, you can embrace the join and leave a 2mm gap and use the paste, or but up and blend the joint paste over. You must use masking tape on the stone before applying the joint paste as to not to mark the stone.
External edging – apply the small edge first them over lap the large edge by 2mm, masking tape the edges then sand, joint fill can be used for any gaps.
Internal edging – butt the edges up and run a sealant down in the shower.
The surfaces are 100% real stone which is naturally porous to oils, grease and limescale. We recommend water based sealants as XSTONE SURFACES®   HARD PROTECT , or any water based hard sealer you can find in diy shops  but always remember to do a patch test with any sealant to make sure it does not change the colour of the stone. 
No reclamations are possible if you use another sealant as the XSTONE SURFACES® – HARD PROTECT. 
Bathrooms and kitchens may need resealing yearly.
Pre-sealed stone can be cleaned with soap and water, after sealing mild detergents and stone cleaners can be used.
