## Overview

3M Marine Adhesive Sealant 4000 UV is a medium-strength, one-component sealant designed for marine and RV applications. It cures in 24 hours to form a flexible, waterproof, and UV-resistant bond on multiple surfaces including aluminum, wood, and fiberglass. Its quick skin formation allows immediate painting, making it perfect for professionals seeking durable, long-lasting seals in harsh outdoor environments.

## Description

3M Marine Adhesive Sealant 4000 UV is a one-component, medium-strength, moisture-curing, gap-filling sealant that cures to form a firm, flexible and waterproof seal on aluminum, wood, gel coat and fiberglass, making it well-suited for marine applications above or below the waterline. This product offers excellent UV resistance for reliable long term performance.

Review: This is for more than boats - I used this product on my RV. Works great. Don’t buy what the camper stores sell. Boat products way better than camper products. Still holding up great after several trips.
Review: Excellent for Sealing RV Roofs - This is an excellent product overall. While marketed as a marine sealant, it can be used in other applications where a waterproof, UV resistant seal is needed. I previously used this to seal around mounting brackets for solar panels on an RV roof. Now, I am removing dicor sealant around vents and other openings on the roof and using this instead. Based on my experience with it around the solar panel mounts, it seems to be far superior to dicor and similar products sold as roof sealant. It sets up quickly and acts as both a sealant and an additional bonding agent. I suspect it is strong enough to hold the solar panels by itself (I used VHB tape as well). The only downside I have found is it does not keep its shiny white appearance over time; it gradually turns dull aand yellowish, but as long as you use it where the appearance does not matter it is a great product.

## Features

- MULTI-PURPOSE MARINE SEALANT: This medium-strength marine sealant bonds portholes, deck fittings, rub rails, screw holes, and stanchion supports while still allowing disassembly
- EXCELLENT UV RESISTANCE: A distinct ability to withstand the sun's rays allows it to excel in challenging outdoor industrial, transportation, and construction environments
- COLOR STABLE: Maintains its color in applications above and below the water line
- FLEXIBLE BONDS: Durable elastomeric adhesion maintains joint movement and withstands stress caused by shock, vibration, swelling and shrinking
- PAINTABLE WHEN WET: Forms a skin in 30-60 minutes but can be painted over with water-based paints immediately after application

## Questions & Answers

**Q: is it paintable?**
A: I did use a permanent marker to match my convertible to to the glued glass window

**Q: Can I use this as a glue/sealer on my wooden hot tub?**
A: This is low strength. I would choose at least a medium strength silicone sealer.

**Q: Will this work to seal the top on a raised roof van?**
A: 3M Marine 4000 UV Adhesive is an excellent UV resistant caulk. The 4000 is especially designed for fiberglas and teak. If you want the toughest structural waterproof joint use the 3M 5200. Do not use the 5200 if you plan to take the raised part off. Once cured the 5200 forms a tenacious glued together joint.

**Q: does this caulk contain polyurethan?**
A: No, unless it goes by another name.  I did not see it listed on the label.  -Jim

### ⭐⭐⭐⭐⭐ Good product, but a secret to know
*by R***E on March 14, 2025*

This is THE product to use for marine applications when you don't want a permanent bond. The issue for me is, it's quite expensive and I only tend to use a fairly small amount at a time for repairs (e.g., installing a replacement stanchion). They tell you that you need to use it within one week of opening. This is only true if you want to dispense it through the nozzle. What I do for small jobs is punch a small hole in the side (I use a nail set or a nail), squeeze a little out using a caulking gun, and spread it with my finger (in a nitrile glove), then slap some tape over the hole. I've now been using one tube of a year on 6 small jobs, and I expect to do more.
