Picking your grout technique according to what you’re trying to achieve is as important as selecting the stone.

Mathios Grout - Standard grouting style

Standard grouting style

The most common technique is to lay each stone one finger width apart from each other and grout between each stone. The grout is deeper than the face of the stone and exposes the stone edges. If the grout colour pairs with the hues of the stone, this makes mostly the stone stand out. For contrasting design result pick up a bold colour opposite of the stone colour.

Mathios Grout - Overgrout style

Overgrout style

The mortar overfills the joints and overlaps the face of the stone. A very popular technique to achieve a rustic and authentic old-world look. It gives such a realistic result to the construction that it’s hard to believe it’s not centuries ago built. Ideal for irregular shaped stones and brickslips. It would also fit nice in an industrial design loft.

Mathios Grout - Flat with the stone face grout style

Flat with the stone face grout style

The grout level is almost flat with the face of the stone. Similar to the standard grouting style but with more active role on the final design. Try to use different colour grout and see how your stonework transforms. For a discreet and always in style look match the grout color with the dominant color shadings of the architectural stone. On the contrary, if you love impactful effect, select grout color opposite of the stone color. With light stone, use dark grout, and with dark stone use light grout.
