Step 4 – Apply Mortar
- Position the tip of the grout bag in the grout line. Squeeze out some mortar along the entire grout line. Be careful not to squeeze out an excessive amount as it will overflow onto the adjacent faux stones and leave you with a messy surface. If some of the individual faux stones are chipped or broken, follow the steps below.

Once the mortar cracks and begins to loosen, proceed to repeat the same action elsewhere along the edge of the stone. Work from several points around the stone until it loosens enough for you to extract it.
