The best patching product depends on the size of your repair and the type of wall. For small, shallow fixes (less than 18 18 inch), DAP DryDex Spackling is the top choice because it goes on pink and dries white, letting you know exactly when to sand and paint.
It's better to use a softer, slower-setting lime-based plaster, like the one developed for Big Wally's line of plaster-repair products, takes about an hour to set, isn't prone to cracking or delaminating, and needs no sanding, which keeps dust to a minimum.
Polycell Plaster Repair is ideal for repairing large areas of damaged plaster. The specially formulated powder is much easier to apply and smooth out than ordinary plaster. It gives a smooth,white, 'ready to decorate' finish to all masonry surfaces and will not slump, shrink or crack.
In some cases, if the plaster is severely damaged beyond repair, it may be necessary to remove the old plaster and start fresh. However, this is not often necessary. By following the proper steps to prepare the wall and applying the plaster correctly, plastering over old plaster can be a simple and successful process.
Follow the manufacturer's instructions to mix dry plaster with water in a large bucket. Pour the plaster from the bucket into a mud pan. Apply a layer of plaster to the crack with a 4” wallboard knife, making sure the layer is even with the rest of the wall. Crack repairs usually need only one layer of plaster.
You can use a reinforced plaster patch for any hole between 5-10cm. Anything under 5cm, I'd be filling. A problem arises when you try to fill a hole bigger than a 20-cent piece where your filler simply falls into the hole.
Spackle is generally better for minor repairs. Joint compound, also called drywall mud or drywall compound, performs better when filling larger holes and cracks.
Plaster is rarely used in modern construction primarily because drywall (gypsum board) is faster, significantly cheaper, and easier to install. While plaster is highly durable and offers better soundproofing and fire resistance, traditional multi-coat plastering requires highly skilled labor and lengthy drying times, making it inefficient for modern housing demands.
Yes. First you must remove any loose bits of plaster. Diluted PVA, then bonding coat these areas to ensure a solid background for your plaster.
Common mistakes in this step are not cleaning the surface properly, not removing dust or old paint, and ignoring cracks and holes. Before you start on a plastering job, you have to make sure that the surfaces you're working on are thoroughly clean. This is to make sure that the plaster adheres properly to the surface.

8 Common Mistakes to Avoid in DIY Drywall Repair
The best filler for plaster walls depends on the size of the repair. For deep holes, powdered Plaster of Paris or setting-type compounds like USG Durabond are ideal.

Plaster types
Hardwall plaster is another popular type of undercoat, which can be applied directly to a surface and then finished with a finer skim coat. While bonding plaster is favoured for tricky surfaces, hardwall is popular as the first coat on masonry, such as brick or cement.
PlasterBond is a rewettable PVA latex bonding agent designed especially for interior/exterior bonding of fresh plaster in patching, plastering and topping applications.
Silicone and Glass: Plaster does not naturally adhere well to silicone or glass surfaces.
Cut a small section of plaster onto the plastering trowel and apply to the repair with vertical and horizontal movements. Press firmly to work the plaster into the damaged area.
Yes, you can plaster over existing plaster, commonly referred to as "skim coating". However, the old plaster must be structurally sound and properly prepped. If the old base is crumbling, cracked, or loose, the new plaster will fail.

Additionally, plaster has superior soundproofing and fire resistance, enhancing both safety and comfort within the building. Drywall is the modern choice between the two materials. Composed of gypsum and two paper layers, drywall is appreciated for its ease of installation and cost-effectiveness.
