Installation Process of Cultured Stone Facade
Installing cultured stone facade requires careful planning, preparation, and execution to ensure a successful and long-lasting result. The following steps outline the general process involved in installing cultured stone on a building facade:
1. Surface Preparation: The existing exterior surface must be cleaned, inspected, and prepared before installing cultured stone. Any debris, dirt, or loose materials should be removed, and the surface should be properly sealed and waterproofed to prevent moisture infiltration.
2. Building Paper Installation: A layer of building paper or house wrap is typically applied over the prepared surface to serve as a moisture barrier and provide additional protection against water intrusion. The building paper should be installed according to the manufacturer's guidelines, ensuring proper overlap and sealing at joints and edges.
3. Metal Lath Installation: A metal lath is then attached to the building paper using corrosion-resistant fasteners to create a stable and secure base for the cultured stone. The metal lath should be installed with the proper orientation and spacing to facilitate proper adhesion of the mortar and stone units.
4. Mortar Application: A scratch coat of mortar is applied to the metal lath using a trowel, creating a rough surface for the cultured stone to adhere to. The mortar should be mixed to the appropriate consistency and thickness, following the manufacturer's recommendations for proper bonding and coverage.
5. Cultured Stone Installation: The cultured stone units are then individually placed onto the mortar bed, starting from the bottom and working upwards. Care should be taken to ensure proper alignment, spacing, and leveling of the stone units to achieve a uniform and aesthetically pleasing finish. Joints between the stone units can be filled with mortar or grout to enhance the overall appearance and durability of the facade.
6. Finishing Touches: Once all the cultured stone units are installed, any excess mortar or grout should be cleaned off the surface using a brush or sponge. The facade can then be left to cure and set for the recommended period before any additional treatments or sealants are applied.
