Tired of running out of cartridges even after working out how many you thought you'd need? Not only is this annoying and time consuming, but it’s also avoidable.
Instead of having to throw a half-empty tube away at the end of the day, extrude a centimetre or so of sealant out of the nozzle and walk away. Depending on how long you leave it before using the cartridge again, use one of the following methods:
If it is only a few hours up to a couple of days, simply pull the now cured centimetre off the top of the nozzle and you're good to go. Any longer than a few days and you will have to change the nozzle. Cartridge nozzles are available to purchase - part number 53001. Typical Yields - To work out quantities (excluding wastage) use the following formula:
|Bead diameter (mm)||Linear Metres per 290ml Cartridge|
V = Volume in ml
W = Sealant Bead Width (mm)
D = Sealant Bead Depth (mm)
r = radius of round bead (mm)
