Floor or wall covering

A floor or wall covering comprising floor or wall panels;

• the panels comprise a substrate and a top layer;
• the top layer comprises a decor layer;
• the panels are provided at least at edges of two opposite sides with coupling parts, cooperating which each other, substantially in a form of male coupling parts and female coupling parts, for coupling the panels to each other in the floor or wall covering;
• the male coupling part is provided at a male edge of the panels;
• the female coupling part is provided at a female edge of the panels;
• a recess is provided at a surface of the floor or wall covering between two panels mechanically coupled to each other by the male coupling part and the female coupling part,
• the recess comprises a first recess cut out or otherwise provided at the female edge through the top layer and extending into the substrate;
• and a second recess cut out or otherwise provided at the male edge through the top layer and extending into the substrate;
• the recess comprises a grouting material;
• wherein a second recess comprises a first undercut in the male edge;
• wherein the first recess comprises a second undercut in the female edge;
• wherein the second undercut has a curved edge.
