So, let’s get our hands sticky (figuratively, of course!) and dive into the fascinating world of waterproof glues in crafting.

Why Use Waterproof Glue?

First off, if you’re working on projects that might come into contact with moisture – think garden decorations, bathroom art, or even coasters for your cold drinks – you’ll want your creations to withstand the test of water without falling apart. That’s where waterproof glue shines!

Types of Waterproof Glue for Crafts

Each type of waterproof glue has its specific set of properties, applications, and handling requirements. It’s essential to choose the right one based on the materials you’re working with and the conditions the final project will face. With the correct waterproof glue, your craft projects can achieve both aesthetic beauty and enduring durability.

Epoxy Resin

  • Composition: Epoxy resin is a thermosetting polymer, coming in two parts – resin and hardener. When mixed, they undergo a chemical reaction, creating a rigid, plastic-like material.
  • Applications: Ideal for projects requiring a strong, durable bond. It’s used in jewelry making, embedding items, and creating high-gloss coatings. Epoxy is also great for filling cracks or bonding disparate materials like wood to metal.
  • Working Time: Generally, you have about 5-30 minutes of working time (depending on the product) before the epoxy starts to harden.
  • Curing Time: Full curing can take anywhere from several hours to a few days.
  • Special Properties: It’s resistant to heat and chemicals, and once cured, it’s incredibly strong and durable.

Mod Podge Outdoor

  • Composition: Similar to the classic Mod Podge, this variant is designed to be more resilient to outdoor conditions.
  • Applications: It’s a sealer, glue, and finish, perfect for outdoor decoupage projects. Use it on items like birdhouses, garden signs, and flowerpots.
  • Drying Time: Dries clear in approximately 15-20 minutes, with a cure time of about 72 hours for optimum water resistance.
  • Special Properties: Offers UV protection to prevent fading and is water-resistant, making it suitable for outdoor use.

Silicone Sealant

  • Composition: Made from silicone polymers, it is flexible and water-resistant.
  • Applications: Excellent for waterproof sealing and bonding, particularly in crafts that require a degree of flexibility or involve glass, metal, and plastic materials.
  • Curing Time: Typically takes 24 hours to fully cure.
  • Special Properties: It’s clear, making it unobtrusive in designs, and can withstand extreme temperatures and weather conditions.

Marine Epoxy

  • Composition: A stronger variant of regular epoxy, formulated specifically for high moisture environments.
  • Applications: Perfect for projects that are constantly submerged in water, like aquarium decorations or boat repairs.
  • Curing Time: Varies by product but generally longer than standard epoxy.
  • Special Properties: Extremely water-resistant and often resistant to yellowing from UV exposure.

Polyurethane Glue

  • Composition: A type of adhesive that reacts with moisture to cure, forming a strong bond.
  • Applications: Works well with a variety of materials including wood, plastic, metal, and ceramics. Great for outdoor furniture or decorations.
  • Curing Time: Usually takes about 24 hours to cure fully.
  • Special Properties: Expands as it cures, filling in small gaps and creating a solid bond.

Tips for Using Waterproof Glue in Crafts

  • Surface Prep is Key: Make sure your surfaces are clean and dry. A little sanding might help with adhesion, especially on glossy surfaces.
  • Ventilation Matters: Some waterproof glues can be a bit fumy, so working in a well-ventilated area is a good idea. Safety first!
  • Curing Time: Patience is a virtue in crafting, right? Waterproof glues often take longer to cure. Make sure you read the instructions for the best results.
  • Test First: If you’re unsure how the glue will react with your materials, do a small test first. It saves heartache later.


Creative Uses

  • Mixed Media Art: Use waterproof glue to combine different elements like fabric, metal, and wood.
  • Custom Coasters: Create your own coasters with tiles and decoupage them, sealing with a waterproof glue.
  • Garden Art: From mosaic stepping stones to decorated flower pots, waterproof glue will ensure your outdoor art withstands the elements.

Cleanup and Storage

Proper cleanup and storage are crucial for maintaining the quality and longevity of your waterproof glues, and to ensure a safe crafting environment. Here’s a more detailed look at these aspects:

Clean Up Consideration:

Wet Glue: If you get any waterproof glue on surfaces where it’s not wanted, it’s easiest to clean it up while it’s still wet. Use a damp cloth or sponge for water-based glues like Mod Podge Outdoor. For epoxies or polyurethane glues, you may need acetone or alcohol (check the glue’s instructions).

Spills on Skin: For skin contact, quickly wipe off the excess glue and then use a suitable solvent (like acetone for epoxy) or soap and warm water for other types. Always use gloves next time to avoid skin contact.

Cured Glue Removal:  Once cured, waterproof glues can be difficult to remove. Physical scraping or sanding might be necessary. For fabrics, freezing the glued item and then trying to peel off the glue can sometimes work.

Tools and Brushes:

  • Cleaning Brushes: For water-based glues, rinse brushes under warm water immediately after use. For stronger glues like epoxies, clean the brushes with appropriate solvents before the glue hardens.
  • Maintenance of Tools: Wipe down any tools like spatulas or spreaders used in glue application. Prolonged exposure to glue can ruin these tools.

Storage Consideration:

Temperature and Environment:

  • Cool and Dry: Store glues in a cool, dry place. Extreme temperatures can deteriorate the glue’s effectiveness. A cabinet in a climate-controlled environment is ideal.
  • Avoid Sunlight: Direct sunlight and UV exposure can degrade some glues. This is especially true for epoxies, which can yellow and weaken under UV light.

Container Sealing:

  • Airtight Containers: Ensure that the glue containers are tightly sealed after use. Exposure to air can cause glues, especially polyurethane types, to harden in the bottle.
  • Preventing Clogs: For glues with nozzles, like silicone sealants, clear the nozzle of any residue before sealing to prevent clogging.


  • Child and Pet Safety: Store glues out of reach of children and pets. Some glues can be toxic if ingested.
  • Fire Hazard: Be aware that some glues can be flammable. Store them away from heat sources.

Shelf Life:

  • Check Expiry Dates: Be aware of the shelf life and expiry dates of your glues. Using glue past its expiry can result in weaker bonds.

By following these cleanup and storage tips, you can ensure that your waterproof glues remain effective for future projects and that your crafting space stays safe and organized. Remember, taking care of your materials is as important as the crafting process itself!
