How Do You Glue Sand to Bases?

Published in Model Basing 2 mins read

You can glue sand to bases using PVA glue, first to stick the sand down, and then by watering down PVA and painting it over the sand to seal it.

Gluing sand to bases is a popular technique for adding texture and realism to model bases, miniatures, or craft projects. The process involves using an adhesive, most commonly PVA glue (also known as white glue or school glue), to secure the sand in place.

Step-by-Step Guide Based on Reference

Based on the provided reference, a simple and effective method is outlined:

  1. Apply PVA Glue: Start by applying PVA glue directly to the area of the base where you want the sand.
  2. Apply the Sand: While the glue is still wet, sprinkle or press the sand onto the glued area. Ensure good coverage.
  3. Let it Dry (Initial Bond): Allow the initial layer of glue to dry to create a basic bond for the sand.
  4. Seal with Watered-Down PVA: I just use pva glue to stick it all down, then water down some pva and paint that over, nice and thin. This step is crucial for sealing the sand and preventing it from flaking off later. Mixing PVA with water creates a thinner mixture that can soak into the sand without forming a thick, smooth layer on top.
  5. Final Drying: Let the watered-down PVA dry completely. According to the reference, When it hardens the sand will keep its texture but go solid.

Why This Method Works

  • Initial Bond: The first layer of neat PVA glue holds the bulk of the sand in place.
  • Penetration: Watering down the second layer of PVA allows it to seep into the gaps between the sand grains.
  • Sealing: As the watered-down PVA dries, it forms a strong, clear bond around the individual sand particles, locking them together and to the base without obscuring the sandy texture.

This technique provides a durable, textured surface ready for painting or further detailing.
