For model horses, especially those made of resin, the best primer choice is a sandable spray primer. These primers offer superior adherence to the resin material and effectively seal the model, creating an ideal surface for subsequent painting.
Why Sandable Spray Primer is Essential
Using a spray primer is mandatory for model horses regardless of the final painting method, primarily because it provides the best overall adherence to the resin. This not only ensures your paint layers will stick properly but also seals the model, preventing issues like paint chipping or uneven application. The "sandable" quality is also crucial as it allows for fine smoothing of the surface, eliminating minor imperfections before detailed painting begins.
Recommended Primer Brands
Several brands offer high-quality sandable spray primers that work exceptionally well for model horses. These options are known for their reliability and excellent results:
- Krylon Sandable Primer: A widely trusted option in the hobby community.
- Plasti-Kote Sandable Primer: Another strong contender known for good adhesion.
- Rustoleum Sandable Primer: A readily available and effective choice.
These brands provide a smooth, consistent base coat, which is vital for achieving a professional finish on your model horse.
Benefits of Using the Right Primer
Choosing the correct primer significantly impacts the quality and durability of your model horse's paint job. Here are the key advantages:
- Optimal Adhesion: Ensures paint layers bind securely to the resin, preventing peeling or flaking.
- Surface Sealing: Protects the model and creates a uniform, non-porous base.
- Enhanced Detail: A smooth, primed surface allows intricate details to stand out and provides a better canvas for fine brushwork.
- Easier Sanding: Sandable primers allow for quick and easy smoothing of the surface, correcting minor flaws or texture issues.
- Uniform Color Base: Provides an even base color, which helps subsequent paint coats appear true to color.
Application Tips for Priming Model Horses
To achieve the best results with your chosen primer, follow these guidelines:
- Clean Your Model: Before priming, thoroughly clean your model horse to remove any dust, mold release agents, or oils. A gentle wash with soap and water, followed by a complete air dry, is recommended.
- Work in a Ventilated Area: Always use spray primers in a well-ventilated space or outdoors to avoid inhaling fumes.
- Apply Light Coats: It's better to apply several thin, even coats rather than one thick coat, which can obscure details and lead to drips.
- Maintain Distance: Hold the spray can about 8-12 inches (20-30 cm) from the model while spraying.
- Allow Drying Time: Let each coat dry completely according to the manufacturer's instructions before applying the next or moving on to sanding and painting.
- Gentle Sanding: If needed, lightly sand the primed surface with very fine-grit sandpaper (600-1000 grit) to smooth out any imperfections. Re-prime lightly if you sand through to the resin.
