Waterproofing your plaster will help maintain its strength and integrity and allow you to enjoy its use in areas where it may be exposed to moisture.

8 Steps to Follow: How to Waterproof Plaster of Paris
Step 1. Prepare the Surface:
Before starting, you need to ensure that the plaster’s surface is clean and free from any dirt or debris.
Use sandpaper or a sanding block to smooth out any rough spots on the plaster lightly. Once finished, wipe down the entire surface with a damp cloth to remove dust particles.
Step 2. Apply Acrylic Sealer:
After the surface is clean and smooth, you can apply an acrylic sealer to help protect the plaster from water damage.
Apply a thin layer of sealer using a paintbrush or roller and let it dry completely before moving on. Make sure to follow the manufacturer’s instructions for best results.
Step 3. Apply Waterproofing Compound:
Once the sealer has dried, you can further apply a waterproofing compound like a liquid or powder to protect the plaster from damage due to water exposure.
Make sure to evenly spread the compound using a brush and let it dry completely before handling the plaster.
Step 4. Seal the Plaster Object:
After the waterproofing compound has dried, you can use a brush to apply another layer of acrylic sealer for added protection.
Make sure not to miss any spots, and let the sealer dry completely before handling the plaster. If your project requires painting, wait until the sealant is completely dry before starting.
Step 5. Allow to Cure:
Allow your waterproofed plaster of Paris object to cure for at least 24 hours before handling it or applying any additional layers of paint or decoration.
This will ensure that all the components are properly bonded and will offer protection against water damage. If the plaster is placed in a damp environment, you may need to apply additional layers of sealant for added protection.
Step 6. Apply the Paint Colors:
Once the waterproofing and sealing steps have been completed, you can apply any desired paint colors. Make sure to use waterproof paint, as this will help keep moisture away from the plaster and further protect it from damage.
If your project requires adding additional decorative items, wait until the paint has dried before starting.
Step 7. Let the Paint Dry Completely:
Allow your paint to dry completely before handling the plaster object. This will ensure that all components are properly bonded and will provide maximum protection against water damage.
If you need to add any additional layers of paint, wait until the first layer has dried before starting.
Step 8. Enjoy Your Finished Product:
Your Plaster of Paris project is now ready for use, thanks to the waterproofing steps you’ve taken! Feel free to enjoy your creation, and remember that with proper care and maintenance, it can last many years.
If you find that the plaster is exposed to moisture, dry it off and apply additional layers of sealant as needed.
Following these steps will help keep your plaster of Paris projects looking great and lasting longer, even in wet conditions. Take the time to properly waterproof your plaster before using it, and you’ll have beautiful results that last.
Follow This Tips When Waterproofing Plaster of Paris:

- Inspect periodically: Check your sealant job every few weeks or months to ensure it still performs well. If any areas appear to be wearing down, reseal them. Always be sure to clean the area before resealing.
