To set sand hard, you can use a fixative solution. This method involves applying a specific mixture that, once dried, will solidify the sand.
The Fixative Solution
The recommended fixative solution is a mixture of:
- PVA (Polyvinyl Acetate) or Mod Podge: These act as the binding agents.
- Water: Used to dilute the binding agent.
- Alcohol: Aids in drying and further solidifies the mixture.
Mixture Ratio
The solution should consist of a 50/50 blend of water and alcohol mixed with the PVA or Mod Podge.
Application Process
Here's how you apply the fixative:
- Combine: Mix the PVA or Mod Podge with equal parts water and alcohol in a spray bottle.
- Spray: Apply the mixture evenly over the sand.
- Drying: Allow the first coat to dry completely.
- Repeat: Apply two to three coats, allowing each to dry fully between applications.
Result
After applying the fixative and allowing it to dry completely, the sand will become "rock hard." This method effectively binds the sand particles together, creating a solid surface.
