Hey everyone, welcome back to my channel! Today, we’re going to be talking about the rules for finishing walls with gypsum plaster. This is a really important topic, especially if you’re planning on doing any DIY home renovations.

Now, I know what you’re thinking: “Gypsum plaster? Isn’t that just for professionals?” Well, not necessarily! With the right tools and techniques, anyone can learn how to finish walls with gypsum plaster.

In this video, I’m going to walk you through the entire process, step-by-step. We’ll cover everything from preparing the surface to applying the plaster to achieving a smooth, professional finish.

So, whether you’re a seasoned DIYer or a complete beginner, this video is for you. Let’s get started!

Pros:

Gypsum plaster is a relatively inexpensive material.
It is easy to apply and dries quickly.
It is a good insulator and can help to reduce noise levels.
It is a fire-resistant material.
It can be used to create a smooth, even finish.

Cons:

Gypsum plaster is not as strong as some other types of plaster, such as cement plaster.
It can be damaged by water, so it is not suitable for use in areas that are prone to moisture.
It can be difficult to apply to uneven surfaces.
It can shrink as it dries, which can lead to cracks.

The type of gypsum plaster you choose will depend on the application. For example, if you are plastering a wall that is exposed to moisture, you will need to use a water-resistant plaster. If you are plastering a wall that needs to be fire-resistant, you will need to use a fire-resistant plaster.

The amount of water you add to the gypsum plaster will depend on the type of plaster you are using and the desired consistency. Generally, you should start by adding a small amount of water and then gradually add more until the plaster is the desired consistency. The plaster should be thick enough to stick to the wall but not so thick that it is difficult to apply.

Prepare the surface. The surface you are plastering should be clean, dry, and free of dust and debris. If the surface is uneven, you may need to apply a leveling compound first.
Mix the plaster. Follow the manufacturer’s instructions for mixing the plaster.
Apply the plaster. Use a trowel to apply the plaster to the wall in a thin, even layer.
Smooth the plaster. Once the plaster has been applied, use a trowel to smooth it out.
Let the plaster dry. The drying time will vary depending on the type of plaster and the thickness of the application. Generally, you should allow the plaster to dry for at least 24 hours before sanding or painting.

Wear gloves and a dust mask when working with gypsum plaster.
Use a drop cloth to protect your floors and furniture.
Clean up any spills immediately.
If you are not sure how to apply gypsum plaster, it is best to consult with a professional.

Before you start plastering your walls with gypsum plaster, it’s important to prepare the room and surface properly. This will ensure a smooth and even finish.

Rotband plaster: instructions for use

Remove all furniture and belongings from the room. This will give you plenty of space to work and prevent damage to your belongings.
Cover the floor and any remaining furniture with drop cloths. This will protect them from dust and splatters.
Clean the walls thoroughly. Use a damp cloth to remove any dirt, dust, or cobwebs. If there is any grease or grime, you may need to use a mild detergent.
Repair any cracks or holes in the walls. Use a patching compound to fill in any imperfections. Once the compound is dry, sand it smooth.
Prime the walls. This will help the plaster adhere to the surface and create a more even finish. Choose a primer that is specifically designed for gypsum plaster.

There are two main ways to plaster walls with gypsum plaster: with beacons or without beacons.

Using beacons:

Beacons are metal strips that are attached to the wall to create a level surface for the plaster. This is a good option if your walls are uneven or if you want to achieve a perfectly smooth finish.
To use beacons, first attach them to the wall using screws or nails. Make sure they are level and spaced evenly apart.
Then, apply the plaster to the wall between the beacons. Use a trowel to spread the plaster evenly and smooth it out.
Once the plaster is dry, remove the beacons and fill in the holes with more plaster.

Without using beacons:

If your walls are already relatively level, you can plaster them without using beacons. This is a quicker and easier method, but it may not be as precise.
To plaster without beacons, simply apply the plaster to the wall using a trowel. Start at the top of the wall and work your way down.
Use a level to check your work as you go. If you notice any uneven areas, smooth them out with the trowel.

When applying gypsum plaster, it’s important to use a thin layer. This will help the plaster dry evenly and prevent cracking.

Here’s how to apply a thin layer of plaster:

Start by mixing the plaster according to the manufacturer’s instructions.
Use a trowel to apply the plaster to the wall in a thin, even layer.
Once the plaster is applied, use a sponge or float to smooth it out.
Allow the plaster to dry completely before applying another layer.

The last stage of plastering is sanding. This will remove any imperfections and create a smooth, polished finish.

Here’s how to sand gypsum plaster:

Once the plaster is completely dry, use a fine-grit sandpaper to sand it smooth.
Start by sanding in a circular motion, then switch to a back-and-forth motion.
Be careful not to sand too hard, as this can damage the plaster.
Once you’re finished sanding, wipe down the wall with a damp cloth to remove any dust.
