How do you solid plaster a concrete wall? The tools used and the process.
To solid plaster a concrete wall in Auckland, you’ll need the following tools and materials:
– Trowels: A selection of trowels, including a float trowel, corner trowel, and finishing trowel, for applying and smoothing the plaster.
– Hawk or plastering board: A tool used to hold and transport the plaster as you work.
– Jointing or pointing trowel: Used for detailed work, such as creating clean edges and corners.
– Plasterer’s brush: Used for wetting the wall and cleaning the tools.
– Straightedge or spirit level: To ensure the evenness and straightness of the plastered surface.
– Mixing equipment: A mixing bucket or trough, and a drill with a paddle mixer attachment for preparing the plaster mix.
– Safety equipment: Gloves, safety glasses, and a dust mask to protect yourself during the plastering process.
– Plaster mix: A cement-based plaster mix suitable for solid plastering. It may include cement, sand, and additives. Brands like Firth, Allied Concrete, or Rockcote offer plaster mixes commonly used in Auckland.
– Bonding agent or primer: A bonding agent or primer is applied to the concrete wall before plastering to improve adhesion between the plaster and the substrate.
– Water: For mixing the plaster and wetting the wall.
– Optional additives: Depending on specific requirements, additives such as plasticizers or water repellents may be included in the mix.
Here’s a general overview of the process:
- Prepare the wall: Clean the concrete wall thoroughly, removing any dust, dirt, or loose particles. Apply a bonding agent or primer to enhance adhesion between the wall and the plaster.
- Mix the plaster: Follow the manufacturer’s instructions to mix the plaster to the desired consistency. Use the mixing equipment to achieve a smooth and lump-free mixture.
- Apply the plaster: Start by “keying” or scratching the surface of the wall with a scratching tool to provide a better grip for the plaster. Apply the plaster mix to the wall using a trowel, working in sections. Spread the plaster evenly and at the desired thickness.
- Level and smooth: Use a straightedge or spirit level to ensure the surface is even and level. Smooth the plaster with a float trowel, removing any excess material and achieving a uniform texture.
- Finishing touches: Use a trowel or jointing tool to create clean edges, corners, and any desired decorative features.
- Curing and drying: Allow the plaster to cure and dry according to the manufacturer’s instructions. Protect the newly plastered wall from excessive moisture and ensure proper ventilation for drying.
