I was recently asked to elaborate on some of the key features I look for in a dedicated epoxy rollcoat.
In the video below I did just that, including the demonstration of a feature I can best describe as "variable viscosity". The formulating philosophy behind variable viscosity is to create a product that has low viscosity when getting the product out on the floor, but then increases in viscosity when you stop moving so it can hold its shape.
This feature is of great importance when it comes to sag resistance (e.g. applying onto a cove), but I have also proven the benefits when it comes to issues like colour separation or shadowing under flake when applied direct to concrete.
It also results in a slightly rippled texture, which provides a more forgiving finish when used as a final coat in warehouse type applications.
