Plastering is a fundamental aspect of construction, providing a protective and aesthetically pleasing finish to walls and surfaces. Understanding the different types of plastering methods is crucial for achieving desired results in building projects. Let's delve into the various types of plastering:
Cement Plastering
Overview: Cement plastering involves a mixture of Portland
cement, sand, and water to create a durable and weather-resistant finish.
Applications: Suitable for both internal and external walls,
especially in damp conditions.
Thickness: Minimum thickness of 10 mm, with variations
depending on wall material and conditions.
Curing: Essential after plastering to prevent cracks and
ensure proper bonding.
Lime Plastering
Overview: Lime plastering utilizes lime, sand, and water,
offering a traditional yet versatile plastering option.
Characteristics: Non-hydraulic hydrated lime is used,
providing a unique aesthetic appeal and allowing for delayed setting.
Mix Ratio: Typically ranges from 1:3 to 1:4 for lime to
sand.
Mud Plastering
Overview: Mud plastering, also known as earthen plaster, is
an eco-friendly and cost-effective plastering method.
Application: Applied in two coats, with thickness varying
between 18 mm for the first coat and 6-7 mm for the second coat.
Advantages: Low toxicity, eco-friendliness, and suitability
for rustic or natural aesthetics.
Stucco Plastering
Overview: Stucco plastering is renowned for its aesthetic
appeal and decorative finish.
Composition: Consists of aggregates, binders, and water,
offering versatility in texture and appearance.
Coats: Typically involves three coats—scratch coat, fine
coat, and finishing coat—with a total thickness of around 25 mm.
Gypsum Plastering
Overview: Gypsum plastering utilizes gypsum instead of
cement, providing a smooth and white finish.
Characteristics: Does not shrink during drying, minimizing
the risk of cracks, and offering excellent aesthetic appeal.
Thickness: Can range from 6 to 20 mm, depending on the
desired finish and application requirements.
