Jointer for Grapevine Joints　Jointer for Grapevine Joint Finishing（Grapevine Jointer）

⚫︎What is the Grapevine Jointer?

A jointing tool made specifically for the Grapevine Joint finish.

An ordinary jointer has a flat face where it meets the mortar. What sets the Grapevine Jointer apart is the ridge that runs down the center of that face.

The ridge leaves a thin line in the joint, like the tendril of a grapevine.

“Grapevine” refers to the vine of a grape plant.

It is one of the American brick joint finishes, a technique used to form a particular design.

It reproduces a design style specific to the United States and gives a wall the atmosphere of a historic building.

What is a Grapevine Joint?

The Grapevine Joint is one of the American brick joint finishes, a method of forming a particular design. It is used primarily for its visual, decorative effect.

The exact date the Grapevine Joint originated is not clear, but it may well have been around for a long time, developing alongside American architectural history and brick masonry practice. It is said to be seen most often on historic buildings from the late 19th to the early 20th century. The Grapevine Joint is popular with some architects and designers, and is used regularly where it suits a particular architectural style or a client’s requirements. Rather than enjoying broad popularity in the general market, it tends to be chosen for specific cultural and historical contexts, or for specific projects.

⚫︎How to produce a Grapevine Joint finish

01. Once the brick tile is set, fill the joints. (Use a mortar pack to pack the jointing mortar in fully.)

02. Wait until the joint is half dry.

03. Strike the joint smooth with an ordinary jointer (one with a flat face).

04. Run the Grapevine Jointer along the joint to score the line.

*Notes on the finish

・If you force the line in after the joint has hardened, iron from the tool will darken it. Finish the joint before it becomes too hard.

・The line will not take unless the jointing mortar is still soft.

・Keep the vertical lines from running across the horizontal ones. (Photo 1, Photo 2)
