Do I need to grout paving slabs?

The short answer is yes. Butt-jointing is sometimes suggested—where slabs are laid edge to edge. This will only lead to tears because contraction and expansion will cause slabs to shift slightly, resulting in damage to the edges. Grout is there as a flexible cushion, stopping excess water from penetrating between the slabs and compromising the mortar bed, and allowing movement between slabs.

Should I seal paving before I grout it?

Not all paving requires sealing, though you may choose to seal anyway, in order to help with cleaning. Higher density, less porous natural stone such as granite and riven sandstone doesn’t absorb dirt easily and may be left unsealed, but we always recommend sealing sawn paving. Paving is best sealed before laying as this means it can be kept undercover, clean and dry while the sealant is applied. If the paving has already been laid, we recommend sealing before grouting.
