One of Europe's largest sealant manufacturers, Krimelte, is looking to develop an innovative sealant applicator for their standard cartridge. The purpose is to achieve an aesthetic and even seal. Such a perfect seal can hardly be achieved while using sealant applicators available on the market today.
The motivation behind this challenge comes from the simple fact that:
It is extremely difficult to caulk joints without soiling the neighbouring surfaces while achieving a beautiful seam at the same time. Usually this is done by masking the neighbouring surfaces with tape, caulking the joint, removing the excess caulk with a spatula and then removing the protective tape.
However most professionals can apply this caulk in one pass (without tape) by moving the caulking gun with constant speed and applying suitable pressure on the trigger/handle of the gun. It is difficult to achieve for most non-professionals.
We want you to design something simple and handy to use.
One of our first ideas is to use peristaltic pump principle: http://www.youtube.com/watch?v=rPNRwhVcOr8&feature=related
There could be a small wheel(s) running on the surface that regulates the amount of sealant dosed.
Applicator should be small, compact and easy to use
Attaches to standard 310ml caulk cartridge with GL15 thread
Typical output 9-15 ml of caulk per running meter
Parts in contact with sealant should have easy access for cleaning
Parts in contact with sealant should be easily replaceable
Applicator needs to function without any power or pneumatic source
Must give out even amount of seal without depending on how fast the applicator is actually moving
