What is PVA glue?

PVA glue, also known as polyvinyl acetate, is a type of adhesive that is widely used for various applications. It is a synthetic polymer composed of polyvinyl acetate, which is a rubbery and thermoplastic material. It is popular due to its versatility, ease of use, and non-toxic nature.

PVA glue is white in color and has a thick, viscous consistency. It is water-based, which means it can be easily diluted with water for different levels of viscosity. It will form a strong bond when it dries, making it suitable for a wide range of materials such as paper, wood, fabric, leather, and some plastics.

It is used in arts and crafts projects, woodworking, bookbinding, and as a general-purpose adhesive for everyday tasks. It is suitable for bonding porous surfaces together and provides a relatively fast drying time, although the exact drying time can vary depending on factors such as temperature, humidity, and the thickness of the application.

It is important to note that craft glue is a type of modeling glue that is not suitable for all applications. It may not be as effective for bonding non-porous surfaces, such as metals or glass, as it is primarily designed for porous materials. In those cases, specific adhesives tailored for those materials would be more appropriate.

How to use PVA Glue on Miniature Bases: A Step-by-Step Guide

There are several steps you can follow to achieve the desired results. Here's a guide on how to use it effectively:

  1. Gather your materials: You will also need, foam, rocks, grit, lightweight bits, hobby sand, acrylic paint, and any desired miniature water effects.
  2. Prepare the miniature base: Clean the miniature base and ensure it is free of any debris or dust.
  3. Applying the adhesive: Use a small brush or applicator to apply it onto the areas of the base where you want to attach foam, rocks, grit, or other lightweight bits. Apply a thin and even layer to ensure good adhesion.
  4. Attaching materials: Press the foam, rocks, grit, or lightweight bits onto the adhesive-covered areas of the miniature base. Gently hold them in place for a few moments to allow them to bond.
  5. Texture paste: If you want to create a texture paste, mix it with sand in a separate container. Add your choice of paint to achieve the desired color. Adjust the consistency by adding more ingredients until you achieve a thick paste.
  6. Applying texture paste: Use a palette knife or a small brush to spread the texture paste onto the desired areas of the base. Sculpt and shape the paste as desired to create texture and terrain features.
  7. Drying time: Allow the mix to dry thoroughly. The drying time can vary depending on the thickness of the application and other environmental factors such as temperature and humidity. 
  8. Optional painting: Once the mixture has dried, you can paint them if desired. Use miniature paints to add color and detail to the base, enhancing the overall appearance.
  9. Water effects: If you wish to create water effects, such as a river or a pond, you can experiment. However, this can be a bit challenging and may require some skill. Apply it in thin layers to mimic the look of water and use additional techniques, such as adding transparent blue paint, to enhance the effect.

Remember to experiment and practice always on scrap materials before working on your final miniature bases. This will allow you to familiarize yourself with the product's behavior and achieve the desired results.

What is the best craft glue for wood kits?

White glue is one of the best glues for wood models for the following reasons:

  • Strong adhesion ability on wood surfaces.
  • Dries to a translucent white color, which does not affect the appearance of the wood.
  • Non-toxic and safe for use on interior projects.
  • Easy clean up and wash with water before drying.
  • Moisture resistance once completely dry.
  • Widely available and affordable.
  • Dries quickly and forms a strong bond.
  • Can be sanded and painted once dry.
  • Ideal for a wide variety of woodworking and craft projects.

Polyvinyl Acetate features 

Unlike other types of adhesives, PVA glue is non-toxic, easy to clean up, and dries clear. It can be easily applied with a brush or spreader, and excess product can be wiped away with a damp cloth. This makes it a great choice for DIY enthusiasts who want an adhesive that is easy to work with and doesn't require any special equipment or tools.

In addition to its bonding capabilities and ease of use, it is also a very versatile product that can be used for a wide range of applications, including woodworking, paper crafts, fabric crafts, and more. It is also compatible with a range of materials, making it an ideal adhesive for mixed-media projects that involve different types of materials.

One of its unique properties is its ability to be diluted with water. This allows for greater control over the viscosity making it easier to apply and reducing the risk of excess PVA glue. Diluting it with water can also help to extend its useful life, as it can be used for thinner applications.

The cure time for the PVA glue is dependent on the room temperature and the thickness of the application, with a complete cure time of six hours. The product comes in a practical "feeding bottle type" packaging that allows for easy application and uses directly on the model or base, extending the lifespan of the product.
