What are the Different Types of Plaster?

Plastering is an important technique used during building construction work for creating smooth, strong surfaces, including walls and ceilings. The type of plaster used can impact the structural look and longevity of a building being constructed or renovated. Different plaster types are available to meet various needs, weather conditions and style choices.

Lime Plaster: Crafted using lime, sand, and water, lime plaster ensures a breathable, flexible, and eco-friendly surface. It provides a natural feel and a touch of textured finish.

Cement Plaster: This plaster is budget-friendly and made using cement, sand, and water. It has a fast curing time. However, creating a smooth and even finish with cement plaster can be difficult.

Gypsum Plaster: Plaster of Paris, made from gypsum powder and water, is fire-resistant, clean, and strong. It sets swiftly and can be applied directly on brick, block, or concrete surfaces.

Hardwall Plaster: This strong plaster is made from dense gypsum that doesn’t dent, crack, or deteriorate from moisture. Its smooth, thick surface is perfect for busy areas.

Stucco Plaster: Stucco plaster is a decorative plaster for indoor and outdoor surfaces. Typically, three layers of stucco plaster are applied, which include a scratch coat, a brown jacket, and a finishing coat.

Bonding Plaster: This is a versatile plaster that aligns perfectly with various surfaces, such as concrete and plasterboard. It is perfect for complex uses where other plasters might struggle to stick.

Multi-Finish Plaster: Made of gypsum plaster and may contain clay, limestone, quartz, and hydrated lime, this fast-drying plaster provides a smooth, flawless finish on various surfaces.

Browning Plaster: A decorative plaster that serves as a base for paint and other applications. It absorbs materials better than bonding plaster, making it ideal for surfaces that soak up substances easily.

Why Plastering is Essential for Your Walls?

Plastering is necessary for your walls to improve the aesthetics of your space, but it also offers practical benefits. Applying plaster to a wall produces a smooth, level surface that gives your room a new look and attracts potential buyers. Depending on the desired finish and functionality, this process involves coating the walls with plaster made from different materials, including gypsum, lime, or cement.

Smooth Finish for the Surface

The brick walls are uneven. By applying the right plaster, you can make them smooth and pretty. This will create an even surface, which is essential for painting the walls. Your house will then have a flawless finish with final coat of paint.

Insulate Walls

Plastering can help to insulate walls, providing better temperature regulation and energy efficiency within a home.

Improve Durability

Brick walls are strong, but with the right plaster coating, they can be more durable and last for an extended period. Plastering safeguards your walls, making them stronger and more durable than unplastered brick walls. In this way, it also protects walls from potential damage and helps the building last longer.

Environmentally-Friendly

Plastering is crucial in protecting walls from moisture and structural damage. A well-applied plaster coat can stop water infiltration, prevent mould and mildew growth, and ensure a healthier indoor environment.

Decorative Appeal

Plastering can make walls look gorgeous. If you want to change a dull, plain surface, you can get help from experienced plastering contractors who can add decorative elements to your walls. This charming finish enables you to create different textures and designs.

How to Plaster a Wall?

Plastering is a task that can be done with some preparation, patience, and know-how. You can plaster your walls to attain a seamless, professional finish.

Gather Your Tools

There are multiple tools and equipment necessary to achieve the desired look. This includes:

  • Paintbrush
  • PVA Adhesive
  • Plastering Trowel
  • Sandpaper
  • Plasterers Hawk
  • Bucket
  • Spray Bottle
  • Plaster
  • Paddle Mixer

Prepare the Wall

To plaster your wall, start by preparing it. Remove loose plaster, dirt, filth, and inadequacies that prevent the new plaster from sticking well. If you’re working on a new plasterboard, close the gaps between the sheets with the help of jointing tape.

Prime the Walls

Next, prime the walls so the plaster will stick better. To do this, use a roller to spread PVA adhesive over the entire surface you plan to plaster.

Mix the Plaster

Once your walls are clean, mix the plaster. Start by filling a clean bucket with water and slowly add the plaster according to the instructions for exact amounts. You can mix it by hand, but a low-speed power mixer works better. Continue mixing until the plaster becomes smooth and lump-free, like thick mud. Use a trowel for moving any plaster stuck to the edges of the bucket into the mix.

Apply the First Coat

To apply the first coat of plaster on a wall, you can follow these steps:

  • Begin at the wall’s bottom left corner.
  • Take a small amount of plaster on your trowel, adding more as needed.
  • Spread plaster upwards with the trowel angled slightly from the wall.
  • Fill sections from bottom to top before moving on.
  • Start with short sweeps, then smooth with longer sweeps.
  • Continue to cover the whole wall.

The first plaster or scratch coat creates a smooth surface for the second coat.

Skim and Smooth

After applying the first coat, wait 20 minutes for it to dry. Afterwards, smooth the wall to eliminate bumps. Use a corner trowel for the corners and edges, as plastering these areas properly can be challenging.

Scraping

It is optional but recommended by most experts before applying the second coat of plaster for better adhesion. You can use a devilling float mainly designed for this purpose, but an old kitchen fork can also work if unavailable. However, if you skip scraping, ensure the first coat is still wet before adding the second coat.

Second Coat

Dilute the second coat of plaster with more water to make it thinner than the first one. Apply a 2mm thick layer and leave the material to dry slightly.

Sand Rough Edges

If there are bumps after plastering, wait for the plaster to dry completely for about 24 hours and then use fine-grit sandpaper to smooth out the rough spots.

Finishing Touches

After the plaster dries to some extent, spray water on the walls. Spray the edges and smooth the surface with a trowel using inward strokes and a clean float to even out any curves. Once fully dry, sand down any excess material.
