Why Gypsum Plaster Is The Best Choice For Interior Plastering?
While several plastering materials are available, gypsum plaster remains the most preferred option for interior walls due to its versatility and range of benefits.
Benefits of Using Gypsum Plaster
- Ease of Application Gypsum plaster is user-friendly and ideal for professional plasterers and DIY enthusiasts. It mixes easily with water and can be applied using a trowel or plastering machine, resulting in a smooth finish.
- Quick Drying Time This plaster dries faster than most other types, allowing you to move on to painting or decorating sooner. The quick setting time also helps reduce the risk of cracking as the plaster cures.
- Lightweight and Strong Gypsum plaster is lightweight, meaning it doesn’t add significant weight to the wall structure. This is particularly important when plastering older walls, as it reduces the risk of stress-related cracks.
- Fire Resistance Gypsum plaster’s fire-resistant properties add extra safety to your interiors. It acts as a fire barrier, preventing the spread of flames.
- Non-toxic gypsum plaster is a safe option for homes with children and pets since it does not emit harmful gases or chemicals.
Popular Gypsum Plaster Finishes
Gypsum plaster can be used to create different finishes, depending on your design preferences:
- Smooth Finish: Ideal for modern, sleek interiors, achieved by applying thin layers and smoothing them out.
- Textured Finish: Created using tools like sponges or rollers to add character to your walls.
- Sand Finish: Add sand to the mixture for a rustic, natural appearance.
- Venetian Finish: A sophisticated technique using multiple layers to achieve a marble-like surface.
Tips For Using Gypsum Plaster Effectively
To get the best results with gypsum plaster, follow these simple tips:
1. Proper Surface Preparation
Before applying the plaster, ensure the surface is clean and free of dust and debris. Using a primer can enhance adhesion, resulting in a more durable finish.
2. Correct Mixing
Follow the manufacturer’s guidelines for mixing gypsum plaster. Avoid over-mixing or under-mixing, as this can affect the consistency and strength of the final product.
3. Thin Coat Application
Apply gypsum plaster in thin layers to prevent cracking. If you need a thicker coat, gradually build the layers to ensure even drying.
4. Finishing Techniques
Allow the plaster to dry completely before sanding or painting. You can add decorative colours or textures to enhance the visual appeal.
Maintenance Of Gypsum Plaster
While gypsum plaster is durable, regular maintenance is required to keep it in top condition. Here are some key maintenance tips:
- Keep Dry: Protect gypsum plaster from moisture using exhaust fans in wet areas like bathrooms and kitchens.
- Regular Cleaning: Dust the surface regularly using a soft brush or vacuum with a brush attachment.
- Repair Damage Promptly: Fix minor cracks or holes immediately to prevent them from worsening.
- Avoid Heavy Objects: Use appropriate wall anchors when hanging heavy items to avoid damaging the plaster.
