Q. Is Gorilla Glue really for the Toughest Jobs on Planet Earth? A. Gorilla Glue is an all-purpose adhesive. If used correctly, it will bond just about anything and for just about forever. It is free of solvents and fillers, which makes it so strong and versatile. There are some things, which are just difficult to glue, such as certain plastics, but we are confident once you’ve tried Gorilla Glue, you will be more than satisfied with the results.
Q. Do I need to prepare the surface first?
A. Make sure surfaces are clean and tight fitting. For smooth, shiny surfaces, try sanding first to roughen up the surface and give the glue something to bite.
Q. Why do I need to add moisture before gluing?
A. Gorilla Glue reacts with moisture to cure – this is what causes the chemical reaction in polyurethane adhesives. Therefore, you need to apply a small amount of moisture to one surface. Then apply glue to the dry surface and clamp. For dense hardwoods, lightly dampen both surfaces prior to gluing.
Q. How much glue do I apply?
A. Apply a thin layer of glue. A little bit goes along way, so apply half as much as you think you are going to need. As a general guide, use one ounce per square foot. Be careful of uncured ‘squeeze out’ or wet glue, particularly on finished furniture. If you need to remove any squeeze out, we recommend wiping with a dry cloth or using a standard paint thinner. Make sure you use the solvent with care in a well-ventilated area. Always wear gloves. Once the glue is dry, it is best removed mechanically: try sanding, chiseling, scraping or picking at it. The glue will not damage tools.
Q. What if I don’t have clamps?
A. Gorilla Glue expands as it cures. To ensure the strongest bond, clamping pressure is needed. There are many different ways to clamp your pieces, but keep in mind the stronger the pressure the better the bond will be. Professional clamps are ideal, but if those aren’t handy, heavy weight from bricks, books, even tape on some smaller repairs will work. The key is to ensure a tight fitting glue line by applying even distribution of pressure.
Q. What is the proper clamp time?
A. When using Gorilla Glue, clamp objects for 1-2 hours. When working with the Gorilla Glue fast curing formula, clamp for 30-60 minutes. And for best results, leave overnight.
Q. How do I clean up?
A. Wipe off excess glue immediately with a dry cloth or standard paint thinner. Do not drag glue over material, instead make small swipes to remove wet adhesive. Make sure you avoid skin contact. Cured glue can be removed with a chisel, scraper or sandpaper.
Q. My bottle of glue has formed a dry layer on top, can I still use it?
A. Any glue that is still in liquid form is perfectly usable and reliable. If the dry layer is very thin, use a pointed tool to poke through it and carefully pull the dry layer through the cap. Squeeze out the excess air from the bottle when you have finished using the glue and store in a cool, dry place.
Q. How do I extend shelf life?
A. Always squeeze out excess air and screw the lid back on tightly. Some people try storing the bottle upside down to keep the liquid glue near the lid. Store the glue in a cool, dry place away from direct sunlight.
Q. Is it truly 100% waterproof?
A. Yes. Gorilla Glue is 100% waterproof. It passes ANSI/HPVA HP-1-2000 Types 1 and 2, easily.
Q. Can you speed up the curing process?
A. No. Gorilla Glue cures in one to two hours, while Gorilla Glue fast curing formula cures in 30-60 minutes. And for best results, both should be left overnight.
Q. What is the temperature range for using the wet glue?
A. From 40–130ºF. For best results use at room temperature.
