Making wall putty with KimaCell HPMC

Making wall putty with KimaCell HPMC (Hydroxypropyl Methylcellulose) involves combining the HPMC with other ingredients to achieve desired properties such as adhesion, workability, and water resistance. Here’s a basic recipe for making wall putty using KimaCell HPMC:

Ingredients:

• KimaCell HPMC (Hydroxypropyl Methylcellulose)
• White cement
• Fine sand (silica sand)
• Calcium carbonate (optional, for filler)
• Water
• Plasticizer (optional, for improved workability)

Instructions:

1. Prepare the HPMC solution:
   • Dissolve the required amount of KimaCell HPMC powder in water. Typically, HPMC is added at a concentration of around 0.2% to 0.5% by weight of the total dry mix. Adjust the concentration based on the desired viscosity and workability of the putty.
2. Mix dry ingredients:
   • In a separate container, mix white cement, fine sand, and calcium carbonate (if using) in the desired proportions. The exact ratios may vary depending on the specific requirements of the application, but a typical ratio is around 1 part cement to 2-3 parts sand.
3. Combine wet and dry ingredients:
   • Gradually add the HPMC solution to the dry mixture while mixing thoroughly. Ensure that the HPMC solution is evenly distributed throughout the mixture to achieve uniform consistency and adhesion.
4. Adjust consistency:
   • Depending on the desired consistency and workability of the putty, you may need to add more water or plasticizer to the mixture. Add small amounts of water or plasticizer at a time and mix thoroughly until the desired consistency is achieved.
5. Mixing and storage:
   • Continue mixing the putty until it reaches a smooth and uniform texture. Avoid overmixing, as this can affect the performance of the putty.
   • Once mixed, the wall putty can be used immediately or stored in a sealed container to prevent drying out. If storing, ensure that the putty is protected from moisture and contamination.
6. Application:
   • Apply the wall putty to the prepared surface using a trowel or putty knife. Ensure that the surface is clean, dry, and free from dust or debris before application.
   • Smooth the putty evenly over the surface, working in small sections at a time. Allow the putty to dry completely before sanding or painting, following the manufacturer’s instructions for drying times.

This basic recipe can be adjusted based on specific requirements, such as desired thickness, adhesion, and texture of the wall putty. Experiment with different ratios and additives to customize the putty to your preferences and application needs. Additionally, always follow safety precautions and manufacturer guidelines when handling and using HPMC and other construction materials.
