What are the differences between different types of adhesives and sealants?

There are various types of adhesives and sealants that differ in composition, application, and strength. Understanding their properties is essential for making the right choice for your specific DIY project.

• Epoxy adhesive: This is extremely strong and therefore ideal when high loads are expected. It adheres to many surfaces and is waterproof, but also quite inflexible.
• Polyurethane adhesive (PU adhesive): This adhesive is waterproof, flexible, and can bond large surfaces. It is well suited for work with wood.
• Cyanoacrylate adhesives (super glue): These adhesives cure very quickly and are excellent for small, quick repairs. They are not flexible and adhere well to plastic, metal, and ceramic.
• Silicone: Silicone is a sealant that is often used in bathrooms and kitchens because of its flexibility and waterproof properties. Silicone adheres to smooth surfaces and is well suited for sealing joints and gaps.
• Acrylic: Acrylic is another sealant that is less flexible but paintable. It is often used to seal small cracks and gaps in walls.
