Creating Exterior Plaster Walls

Plaster or stucco, as it is called when used on exterior surfaces, is an ancient building material. Plaster creates different textures on a hard surface and finishes can be applied by adding coloring or painting. Although it is called plaster, or stucco, it is a mixture of cement, sand, and water. Originally, the bonding agent was lime, not cement, and is used frequently in mixtures today. Stucco was used in the buildings of ancient peoples in the southwestern United States, and is still used in this region.


  1. Build the basis of a wall by using poured concrete, concrete block or wood paneling. Make the base for concrete wider than the width of the wall to give an area of protection plaster or stucco finish blocks. Make a wood wall with concrete posts and line them with plywood or chipboard; place the coating on either side of the fence.
  2. Adhere a waterproof protectant with a staple gun on wooden wall cover and adjusts the expanded metal wall with galvanized nails and a hammer. Apply plaster directly on the masonry wall. Install a wire mesh at the bottom of the wooden wall to allow moisture to drain and get behind the stucco. Leave a space at the foot of the wall so the stucco surface is not in contact with the ground.
  3. Apply the stucco traditionally in three layers or the newest “single layer” actually uses two layers. Spread the first layer, about 3/8 inch (0.95 cm) thick with a flat rectangular bricklayer. Let it settle and scratch horizontal lines with the serrated edge of the blade of the trowel, broom or rake. Skip this step in the process of a single layer. Let the bond coat cure at least 24 hours, keep it moist during healing.
  4. Place the second layer, also approximately 3/8 inch (0.95 cm) thick layer of adhesive, this is the first, or base coat in two steps. Smooth it by rotating a ruler along the surface from top to bottom. Removes excess scraped material from the bottom of the wall or fence. Cure this layer for 24 hours, keeping it moist during the process.
  5. Finish the wall or fence with a 1/8 inches (0.35 cm) layer of stucco plaster using a spoon rectangular or pointed mason. Spread the material gently, and then add any texture; stucco fences and boundary walls are finished naturally in its textures, without being absolutely smooth. Let the finishing coat dry and paint if the mixture is not colored.
