Everbuild Dual Purpose Foam Cleaner - 500ml Description Dual purpose foam cleaner is used to remove wet/uncured foam. Attaches to gun foam applicator for purging through, also includes spray nozzle for use without applicator to remove wet foam from outside the gun and from most building substrates. Application The following tips are recommended for cleaning foam in all common situations. Please note if the foam in a gun is allowed to cure, then the gun will become completely useless, as no solvent will dissolve PU foam once cured. The following guidelines are given to avoid unnecessary cost of replacement. Gun foam may be left attached to a gun for a maximum of 7 days after use. If left for longer, there is a serious risk of the foam curing from the nozzle inwards or propellant leaking out. If foam is left attached to the gun, spray gun foam cleaner over the outside of the discharge nozzle before storage to remove any residues which may seize up the valve. When you have finished using foam on a project, and do not intend to use the gun again within 7 days, remove the the foam can, exercise care and wear gloves & goggles. When you have read the usage/safety instructions on the can, attach gun foam cleaner to your gun by screwing the canister onto the gun adapter until it will go no further, taking care not to cross thread or over tighten the canister. Pull the trigger on the gun to release the solvent into the gun barrel and discharge the solvent into a suitable container for disposal. Only stop discharging the cleaner when the solution being ejected from the gun is completely clear. Leave the gun foam cleaner attached to the gun for 5 minutes to allow the solvent in the gun to work on the residues inside. Pull the trigger once again until only clear solvent emerges. Leave for a further 5 minutes and repeat this process 2 or 3 times until the gun is completely clear. Storage Store in cool, dry conditions between 5 and 25C. Shelf life Use within 12 months.
