PURBOND TIPS

       Wear gloves or you will have black marks on your hands for a couple of days until it wears off.  It will not come off with acetone or soap and water.

       Wear multiple pairs of disposable gloves; if you get PURBOND on them, peel the outer one off and keep working.

       Wipe the surfaces being joined with a damp cloth (water) and you will get a stronger cure.  PURBOND is a moisture cure.

       Clamp joints tightly.  If you dont, the foaming action will push the sides apart and you will have a weak joint.  Strength comes from the two faces being firmly squeezed together.

       You only need a little.  250ml per square metre.  Just a bit more than if you were painting.

       Only apply PURBOND to one surface.

       Spread PURBOND over the whole surface.

       A plastic scraper works well (e.g. the side out of an icecream bucket etc.)

       DO NOT scrape off the squeeze out before it cures.  This will only spread it further and make a bigger mess.  It cleans off easily after it cures.

       Leave until dry and it cleans off easily with a knife, chisel, plane or sanding.

       You can use masking tape to prevent squeeze out getting onto unwanted places.

       Put cardboard or plastic on the floor so any excess will not stick if it drips on the floor.

       Freshly cut or sanded surfaces (less than six hours since cutting or sanding) result in the best joints. Even oily timbers such as Teak and Huon Pine.

       Timber burnished with blunt planer blades could give poor results.  Sand cross grain with fresh, sharp medium (120 grit) sand paper.  Clean metals, plastics and fibreglass with detergent/degreaser and wash off with water before gluing.

       Roughen plastics, fibreglass and metals with coarse (40-80 grit) sandpaper for best results.

       Avoid surface contamination with oils, greases, silicones, oil from your hands, the wax from some white or grey sandpapers etc.  (Use yellow, red, green or black sandpaper, not white or grey.)  They will act as a release agent.

       PURBOND will not bond polyethylene, polypropylene, Teflon, nylon or mylar.

       PURBOND bonds to other plastics, but may only have limited strength.  Do a test piece to check the suitability.

       PURBOND is compatible with styrene foams and is a great way to bond them.

       The get maximum shelf life, store the bottle upside down.

       Throw away PVA, Cross linked PVA,  Aquadhere etc.  They might be cheaper but they just wont perform like PURBOND.  They creep, and despite some manufacturers claims, they are not waterproof, they gum up your tools and just dont work all that well.

       Remember, no adhesive can glue absolutely anything to absolutely anything with absolute strength.  For important items, do a test piece first and make sure it does what you want.
