Safety Information

Warning: Harmful if swallowed or inhaled.  Irritating to eyes, respiratory system and skin.  In case of contact with eyes or skin, rinse immediately and thoroughly with plenty of water and seek urgent medical help.  May cause sensitisation through inhalation.  Use in a well-ventilated area.  In case of insufficient ventilation, you must wear suitable respiratory equipment.  In case if  accident or if you feel unwell seek medical advice immediately.  Take the product bottle and any labelling with you when you seek medical assistance.  This product will stain hands - wear gloves for protection, if required.

Directions For Use

If you are using Gorilla Glue for the first time or are bonding a new substrate, always do a test piece to assess performance first.

Preparation of Surfaces:

  • All surfaces must be clean, dust free, and tight fitting. For glass-like surfaces, scuff up the material to give the glue something to hold onto.
  • Lightly dampen one surface with water. For dense woods like Oak or Maple, lightly dampen both surfaces prior to gluing. This not only helps open up the pores of the wood, it helps speed up the catalysation process.
  • Spread Gorilla Glue onto the other surface. (Avoid skin contact as glue temporarily stains). Squeeze air from bottle to prolong shelf life. If you do get glue on your hands, scrub with soap & water.


  • The glue will start to "set up" within about 15 minutes at recommended temperature and humidity.  Clamping of parts to be joined is necessary during cure. Alternatively, use heavy objects to achieve clamping pressure. For gluing lighter objects, rubber banding is sufficient. Surfaces should remain under pressure for 1-4 hours, depending on temperature, humidity, and moisture content. Wet glue will foam in volume 3-4 times.


  • Remove uncured "squeeze out" with denatured or rubbing alcohol, thinner, or other common solvents. Fully hardened squeeze out is easily removed with a chisel, scraper, or sandpaper and will not damage tools. Scrub hands with soap and water.
