How to Build an Arch

A recent project involved building 2 arched doorways and an arched serving hatch. The best way to form an arch is to use an arched template made from wood (or cut up small bricks as shown in the video), that's wide enough so the blocks can rest on while the mortar sets.
Position the template in the exact spot where you want the arch, and make sure it's well secured. Then lay the blocks along the top of the template and mortar them together. When completely dry, remove the template and the block arch will stand on its own. www.plastering4u.com
