19. ues Tackiness is developed very rapidly and yet it is possible to adjust the assembly into its final position without difficulty NO HEAVY CLAMP ING REQUIRED In most cases hand pressure is sufficient to give flexible bond of enormous strength Provided the wood is not warped light clamping is all that is required When dry the joint is stronger than the wood Weldbond can be used on flat surfaces on edges and on end grain Bond strength on mortise joints dove tailing and level surfaces exceeds 1 700 Ibs per square inch It eliminates the need for plugging when fixing shelves and brackets Wood lintels can be easily fixed over door and window frames using Weldbond METHOD Clean surface to be coated Rub or brush a full even coat of Weldbond to each surface to be bonded Allow surfaces to become tacky then bring together and clamp lightly This eliminates any problem of glue rinse out caused by pressure being applied to a thick liquid Particularly important with hardwoods such as ash walnut and oak END GRAIN BONDING Prime both surfaces with a solution of 1 part Weldbond and 5 parts water allow to dry Make final bond with full strength Weldbond applied to both surfaces GLUE LINE REMOVAL BEFORE STAINING OR FINISHING To clean up a glue line drip or run from a joint wash thoroughly with warm water and sponge until surface is free of all glue This must be done within 20 minutes after gluing When wet the glued joint will accept a
20. ur e DECORATIVE CRAFT PURPOSES o Weldbond will bond marble glass and most metals Metals must be chemically cleaned prior to use with a high quality solvent such as acetone nail polish remover and surface roughed up with fine emery paper Glass and marble must also be cleaned If possible the marble surface to be bonded should be slightly roughened with emery paper particularly if a large area is going to be bonded and needs additional grabbing power The recommended method is to use a Semi contact type bond apply a thin coat of Weldbond to both surfaces and allow to become slightly transparent Once the surface becomes shiny or partially clear bring the two surfaces together and allow to come to a full cure If the drying needs to be sped up use hot air from a hot air register heater or hair dryer NOTE Weldbond is not a solvent based adhesive It is an air dried chemical cure If you allow it to dry slightly before actually making the bond then you reduce the curing time for the bond but you may reduce the strength The curing time for a bond of this type is 1 to 3 days before allowing rough handling GLASS AND STAINED GLASS Weldbond is widely used in glass applications because it dries clear It is important to note that because Weldbond cures from exposure to air it can take up to 48 hours or longer to cure large pieces of glass Almost anything can be bonded to glass or porcelain when using Weldbond Use emery paper on me
