Plasterkey is used to enhance the bond of plaster to various surfaces, particularly when working with gypsum-based plaster or sand/cement mixes.
Understanding Plasterkey Application
Using Plasterkey simplifies the plastering process by providing an excellent bonding agent, ensuring a stronger and more durable finish. There are two primary methods for its application, depending on your plastering needs.
1. Direct Application for Gypsum-Based Plaster
When applying gypsum-based plaster, Plasterkey acts as a keying agent, allowing for direct application of plaster onto a wet surface.
- Preparation: Ensure the surface is prepared and clean.
- Application: Apply Plasterkey evenly to the prepared surface.
- Plastering: While the Plasterkey is still wet, immediately apply your gypsum-based plaster.
- Finishing: Complete the plastering in a single operation for best results. This method creates a strong, reliable bond between the substrate and the plaster.
2. Adding to Sand/Cement Plaster Mix
Plasterkey can also be integrated directly into a sand/cement plaster mix to significantly improve its bonding strength.
- Mixing Ratio: Add Plasterkey to the sand/cement plaster mix at a ratio of 10% of the total water content.
- Benefits: This inclusion results in a stronger bond, reducing the likelihood of cracking or delamination over time, and enhancing the overall durability of the plaster.
Application Methods for Plasterkey
Plasterkey is versatile in how it can be applied to surfaces, accommodating different project sizes and preferences.
- Brush: For smaller areas or intricate work, a brush provides precise application.
- Roller: For larger surfaces, a roller allows for quicker and more uniform coverage.
By following these methods, Plasterkey helps achieve professional and long-lasting plastering results.
