how much paint to order for a horse trailer
Painting a horse trailer is a great way to refresh its look and protect it from rust and weather damage. However, estimating how much paint you need can be tricky, as it depends on the size of the trailer, the type of paint used, and whether you’re applying a primer and multiple coats.
In this guide, we’ll break down the factors that influence paint quantity, provide a rough estimate for different trailer sizes, and give some tips for achieving the best results.
Factors That Affect Paint Quantity
Before ordering paint, consider the following factors:
1. Trailer Size and Surface Area
The larger your trailer, the more paint you’ll need. A small two-horse trailer requires significantly less paint than a large gooseneck trailer.
- Small (2-horse bumper pull): ~100–150 sq. ft.
- Medium (3-4 horse bumper pull): ~150–250 sq. ft.
- Large (Gooseneck trailer): ~250–400 sq. ft.
2. Type of Paint
- Automotive paint (best for durability, high-gloss finish)
- Rust-resistant enamel (budget-friendly, good for metal surfaces)
- Spray-on bed liner or epoxy paint (for heavy-duty protection)
Each type has different coverage per gallon, so check the manufacturer’s recommendations.
3. Number of Coats
- Single coat: Offers basic coverage but may not last as long.
- Two coats: Recommended for even coverage and durability.
- Primer + 2 coats: Ideal for preventing rust and ensuring a long-lasting finish.
4. Painting Method
- Spray gun: More efficient and uses less paint.
- Brush and roller: Requires extra paint due to thicker application.
Paint Estimate Chart for Horse Trailers
| Trailer Size | Primer (1 coat) | Paint (1 coat) | Paint (2 coats) |
|---|---|---|---|
| Small (2-horse bumper pull) | 1-1.5 gallons | 1.5-2 gallons | 3-4 gallons |
| Medium (3-4 horse bumper pull) | 1.5-2 gallons | 2-3 gallons | 4-5 gallons |
| Large (Gooseneck trailer) | 2-3 gallons | 3-4 gallons | 6-8 gallons |
These estimates assume using a sprayer. Brushing or rolling may require 20-30% more paint.
Additional Supplies You May Need
- Primer (if painting over bare metal or rust)
- Clear coat (for extra durability and shine)
- Sandpaper or wire brush (to prep the surface)
- Masking tape & drop cloths (to protect windows and trim)
Final Thoughts
For a standard 2-horse trailer, plan for 2-4 gallons of paint for full coverage. A large gooseneck trailer may require 6-8 gallons depending on the number of coats. Always buy a little extra to account for touch-ups.
