The Impact of Grout

Grout (and sometimes the lack of grout) has an amazing impact on the look and authenticity of stonework. Selecting the desired grout technique and grout color is often as important as selecting the stone. Here we will expore expert stone grout techniques that can be used in a variety of stone projects. Wether you call it thin stone veneer, faux stone veneer or artificial stone veneer, it always benefits from grout. There are three distinct stone grout techniques: Standard Joints (Raked), Dry- Stack Joints and Overgrout Joints.

Dry-stack Joint

Dry-stack joint stonework is accomplished by “dry” fitting each stone prior to installation. Each piece can be laid with virtually no joint. Even though you’ve used mortar to set the stone to the surface, when complete, the finished look will appear as though no mortar was used to install the stone. The intent of a dry-stack look is a tightly stacked stone appearance.

Standard Joint

A standard joint (raked) is achieved by laying each stone roughly one finger width apart from each other, then grouting between each stone. The semi-dry mortar is later “raked” with a variety of tools ultimately achieving a consistent depth and giving it that distinctive raked out look.

Overgrout Joint

Overgrout, an increasingly popular way to achieve an old-world look, is sometimes referred to as sack finish. Today, trowels, tuck pointers – even fingers – are used to achieve the overgrouted or sacked look. This technique tends to make the stonework appear rustic and aged. The grout overlaps the face of the stone, widening the joints and making them very irregular.
