The primary purpose of smoothening these surfaces is to protect moisture intrusion, prepare them for painting, and to add other aesthetic materials.
Types of Plaster
Shepparton plasterer applies a wet material over bricks or blocks, and using equipment such as wood float or skimming float; he levels the surface to make it smooth. The wet material is the plaster that uses different materials such as sand, lime, cement, and gypsum.
Cement Plaster: This plaster uses cement as a binder. Shepparton plasterer uses it for damp conditions and applies just one coat. It’s highly resistant to abrasion and has excellent adhesion strength.
Gypsum Plaster: It’s also known as plaster of Paris and is mostly used as a finish coat and undercoat. Gypsum has replaced cement and lime due to its full application, lightweight, perfect rust-preventive agent, and prevents shrinkage.
Lime Plaster: It’s a type of plaster that uses lime as a binding material. This is a mixture of sand, hydrated lime, and water. Lime plaster shrinks or cracks after drying. When making this plaster you add synthetic or animal hair.
Desirable Properties of Plaster
Suitable plaster should have specific properties both in the wet and hardened state. They include;
- In Wet State
Workability: It refers to the ease to work with. Plaster should be natural to place, tool, float, and shape. Several factors influence this quality like weight, adhesion, spreadability, and cohesion. According to Shepparton plasterer, you should proportion the materials and mix them properly for you to get better workability.
Adhesion: The plaster should have excellent adhesive abilities. It should stick or adhere to the substrate well. The water-cement ratio, aggregate, and the base absorptive characteristic nature influence this quality.
Cohesion: The plaster can stick together. This quality is inspired by cement, particle, shape, size, and graduation, as well as the quantity of water and aggregate. Shepparton plasterer states that a cohesive plaster should be without sloughing, sagging, and delaminating.
- Hardened Plasterer
Bond: It’s the adhesion that exists between materials of various kinds. You can bond between different plaster coats through mechanical keying, chemical bonding, or the combination of the two factors.
Weather Resistance: The dried plaster should withstand weathering. It should have the ability to resist freezing and thawing, rain penetration, moisture, and thermal changes. Further, it should be resistant to aggressive chemicals like acid rain.
Shepparton plasterer recommends the use of air-entrained plaster, particularly in places with deicing chemicals and snow.
Tensile Strength: A plaster with high tensile strength has a higher ability to resist cracking. You can obtain optimum crack resistance when you properly cure plaster that is well proportioned and consolidated. Thus, a plastering shouldn’t look good now but crack after some years.
Types of Finishing
Pebble Dash Finish: A finish where crush stones or small pebbles are dashed on a freshly applied coat of plaster. They are then pressed on the surface using a wooden float, thus giving it an aesthetic appearance.
Rough Cast: It’s a finish whose mortar has relatively larger coarse aggregates. Shepparton plasterer recommends this plastering for external renderings.
Scrapped Finish: It’s a finish that use plate scrap or steel blade to scrape the partially dry mortar. This finish is less liable to cracks.
Smooth-Cast Finish: It is a level, smooth surface done using mortar made by mixing cement and fine sand at a ratio of 1:3. It uses a wood float or skimming float to spread the plaster, thus the smooth surface.
Textured Finish: The finish has ornamental patterns created by different tools used in applying and levelling the final coat.
