Plastering Aerated Concrete Walls

Hey everyone, welcome back to my channel! Today, we’re diving into the world of plastering aerated concrete, both inside and outside your home.

Now, aerated concrete is a fantastic material for construction, but it does require a specific approach when it comes to plastering. In this video, we’ll be covering everything you need to know, from the tools and materials you’ll need to the step-by-step process of applying the plaster.

Whether you’re a seasoned DIYer or just starting out, this video will provide you with the knowledge and confidence to tackle this project yourself. So, grab your tools, let’s get started, and transform your aerated concrete walls into beautiful and durable surfaces!

Aerated concrete is a lightweight and porous material that offers several advantages for construction, including:

• Excellent thermal insulation: Aerated concrete walls help to regulate indoor temperatures, reducing energy costs for heating and cooling.
• Fire resistance: Aerated concrete is non-combustible, providing an additional layer of safety in case of a fire.
• Soundproofing: The porous structure of aerated concrete absorbs sound waves, making it an ideal material for walls and floors in areas where noise reduction is desired.
• Lightweight: Aerated concrete is significantly lighter than traditional concrete, reducing the load on foundations and making it easier to handle during construction.
• Easy to work with: Aerated concrete can be easily cut, drilled, and shaped, allowing for greater flexibility in design and construction.

Outside Plastering:

• Choice of plaster: For exterior plastering of aerated concrete, it’s crucial to choose a plaster specifically designed for this material. These plasters typically have a higher water vapor permeability, allowing the walls to breathe and preventing moisture buildup.
• Preparation: Before applying the plaster, the aerated concrete surface must be clean, dry, and free of dust or debris. It’s also recommended to apply a primer to improve adhesion.
• Application: The plaster should be applied in multiple thin layers, allowing each layer to dry completely before applying the next. This ensures proper adhesion and prevents cracking.
• Finishing: Once the plaster has dried, it can be finished with a paint or textured coating to achieve the desired aesthetic.

Inside Plastering:

• Choice of plaster: For interior plastering of aerated concrete, a variety of plaster types can be used, including gypsum plaster, lime plaster, and clay plaster. The choice will depend on the desired finish and the specific requirements of the project.
• Preparation: Similar to exterior plastering, the aerated concrete surface must be clean, dry, and free of dust or debris before applying the plaster.
• Application: The plaster should be applied in multiple thin layers, allowing each layer to dry completely before applying the next. This ensures proper adhesion and prevents cracking.
• Finishing: The finished plaster can be painted, wallpapered, or left bare, depending on the desired aesthetic.

Work Technology:

• Tools and equipment: The tools and equipment required for plastering aerated concrete are similar to those used for traditional plastering. These include trowels, floats, buckets, mixing tools, and safety gear.
• Mixing: The plaster should be mixed according to the manufacturer’s instructions, ensuring a smooth and consistent consistency.
• Application techniques: The plaster should be applied using proper techniques to ensure even coverage and a smooth finish.

Internal Plastering of Aerated Concrete Walls Indoors:

• Benefits: Internal plastering of aerated concrete walls provides a smooth and aesthetically pleasing surface, improves the thermal insulation of the walls, and helps to regulate indoor humidity.
• Considerations: When plastering aerated concrete walls indoors, it’s important to consider the specific requirements of the project, such as the desired finish, the type of plaster to be used, and the ventilation of the room.

Additional Tips:

• Always wear appropriate safety gear when working with plaster, including gloves, eye protection, and a respirator.
• Follow the manufacturer’s instructions for the specific plaster you are using.
• Allow the plaster to dry completely before applying any finishes.
• If you are unsure about any aspect of the plastering process, consult with a professional plasterer.

By following these guidelines, you can successfully plaster aerated concrete on the outside and inside of your house, achieving a durable and aesthetically pleasing finish.

The first step is to choose the right plaster for your aerated concrete. There are two main types of plaster: cement-based and gypsum-based. Cement-based plaster is more durable and water-resistant, making it a good choice for exterior walls. Gypsum-based plaster is easier to work with and has a smoother finish, making it a good choice for interior walls.

Once you have chosen your plaster, you need to prepare the surface of the aerated concrete. This involves cleaning the surface to remove any dirt or debris, and then applying a primer. The primer will help the plaster to adhere to the aerated concrete.

The next step is to mix the plaster according to the manufacturer’s instructions. Be sure to use the correct amount of water, as too much water will make the plaster too thin and too little water will make it too thick.

Once the plaster is mixed, you can start applying it to the aerated concrete. You can use a trowel or a spray gun to apply the plaster. If you are using a trowel, be sure to apply the plaster in a thin, even layer. If you are using a spray gun, be sure to follow the manufacturer’s instructions.

Once the plaster has been applied, you need to finish it. This involves smoothing out the surface of the plaster and removing any imperfections. You can use a trowel or a sponge to finish the plaster.

Always use a primer before applying plaster to aerated concrete. This will help the plaster to adhere to the surface and prevent it from cracking.

It is important to apply the plaster in thin layers. This will help to prevent the plaster from cracking and will also make it easier to finish.

You can use a trowel or a sponge to finish the plaster. A trowel will give you a smoother finish, while a sponge will give you a more textured finish.

It is important to let the plaster dry completely before painting or wallpapering it. This will help to prevent the plaster from cracking or peeling.

Plastering aerated concrete is a relatively simple process, but it is important to follow the correct steps to ensure a successful outcome. By following the tips in this guide, you can be sure that your plaster job will be both beautiful and long-lasting.
