CornerFlex, Inc. began in 2008 when Greg Amundson, a Scandia, Minnesota resident, realized there was a need for a better caulking product that was a healthier alternative to traditional caulk and could be used by literally anyone.

Through trial and error, Greg accomplished his goal and developed EasyCaulk™. He invented a “flexible wing design” that allows for a quick and easy alternative to traditional caulk with a high quality finish that resists moisture, mold and mildew and lasts for years. Additional do-it-yourself home improvement products have since been developed and more are in the works.


We are committed to a healthier caulk alternative and environmentally safe packaging materials. CornerFlex products have always had the goal of developing a healthier alternative to traditional solutions without the toxic fumes or volatile organic compounds after application. In addition, our packaging is easy to open, designed to protect the product and most importantly, recyclable.
