Top 5 Best Adhesive For Marine Vinyl Flooring
1. 3M Marine Grade Adhesive 5200
3M 5200 is a legendary adhesive in the boating world. It’s known for its incredible strength and waterproof capabilities. This stuff creates a permanent bond that can withstand the harshest marine environments.
Pros:
- ✅ Unmatched strength and durability
- ✅ Excellent water resistance – fully waterproof
- ✅ Bonds to a wide variety of materials
Cons:
- ❌ Very slow curing time (can take several days)
- ❌ Can be messy and difficult to work with
- ❌ Forms a permanent bond – difficult to remove later
Verdict: Best for permanent installations where strength and water resistance are the top priorities, and you don’t mind the long cure time.
2. Roberts 6700 Marine Grade Adhesive
Roberts 6700 is a popular choice for marine vinyl flooring because it offers a good balance of strength, ease of use, and relatively fast grab. It’s designed specifically for vinyl and provides a strong, waterproof bond.
Pros:
- ✅ Strong bond specifically for vinyl flooring
- ✅ Good water resistance
- ✅ Easy to apply with a trowel
Cons:
- ❌ Not as strong as 3M 5200 for demanding applications
- ❌ May require longer drying time in humid conditions
- ❌ Can be difficult to remove completely if needed
Verdict: A solid all-around choice for most marine vinyl flooring projects, offering a good balance of performance and ease of use. Ideal for larger areas where quick grab is helpful.
3. DAP Weldwood Contact Cement
DAP Weldwood Contact Cement is a versatile adhesive that creates a strong, instant bond when surfaces are brought together. It’s a good option for adhering vinyl to various substrates, but requires careful application.

Verdict: Best for small areas or intricate designs where a fast, strong bond is needed. Use with caution in areas prone to constant water exposure. I used this on a small section of my boat near the console, and it’s held up great, but I wouldn’t trust it for the whole deck.
4. Henry 640 Vinyl Flooring Adhesive
Henry 640 is a budget-friendly option designed for vinyl flooring installation. While not specifically a marine adhesive, it can provide a decent hold in less demanding marine environments.

Buying Guide
Choosing the right adhesive for your marine vinyl flooring project depends on several factors. Here’s what to consider:
- Water Resistance: This is crucial. Look for adhesives specifically labeled as “marine grade” or “waterproof.”
- Strength: Consider the amount of stress the flooring will endure. High-traffic areas or areas subject to flexing will require a stronger adhesive.
- Cure Time: Some adhesives cure quickly, while others take several days. Factor this into your project timeline.
- Ease of Application: Are you comfortable using a trowel, or do you prefer a brush or spray application?
- Material Compatibility: Ensure the adhesive is compatible with both the vinyl flooring and the substrate (the surface you’re gluing to).
- Temperature and Humidity: Some adhesives are more sensitive to temperature and humidity than others. Check the manufacturer’s recommendations.
- Budget: Prices vary widely. Balance your needs with your budget.
- Long-term durability: It’s worth investing in quality adhesive to ensure your boat flooring lasts long.
Before you start, thoroughly clean and prepare the surface. Remove any old adhesive, dirt, or grease. A clean surface is essential for a strong bond. Always test the adhesive in an inconspicuous area first to ensure compatibility and desired results.
