Glue types

Every recommendation on this site starts from the glue family, not the brand. Compare the six families side by side — the scales are honestly qualitative, because hard numbers belong to specific products, not whole families.

• EpoxyTwo parts mixed together. The strongest, most gap-tolerant choice for rigid materials like metal, ceramic, and glass.Best for · Metal, Ceramic, Glass, Plastic, Concrete & stone, WoodGap fillingFlexibilityWater resistance
• Super glue (CA)Cyanoacrylate. Bonds in seconds on small, tight-fitting parts — but brittle, and poor across gaps.Best for · Rubber, Plastic, Ceramic, Metal, GlassGap fillingFlexibilityWater resistance
• Wood glue (PVA)The default for wood-to-wood. A cured PVA joint is stronger than the wood itself.Best for · WoodGap fillingFlexibilityWater resistance
• PolyurethaneWaterproof and multi-material. Expands as it cures, so use a light touch and clamp well.Best for · Wood, Metal, Concrete & stone, Ceramic, Rubber, FabricGap fillingFlexibilityWater resistance
• Construction adhesiveHeavy-duty cartridges for walls, trim, paneling, and subfloor. Grabs fast and fills uneven surfaces.Best for · Wood, Concrete & stone, Ceramic, Metal, PlasticGap fillingFlexibilityWater resistance
• SiliconeStays flexible and waterproof for decades. Seals glass, tubs, and sinks rather than bearing loads.Best for · Glass, Ceramic, Metal, PlasticGap fillingFlexibilityWater resistance
