Get a Better Bite

Recently there has been some discussion among CTI dealers and CTI corporate about using the "Magic Trowel" and or other squeegee type tools for skim coat applications.

Historically CTI has always promoted and taught skim coat application with stainless steel pool trowels. Application with the trowels ensures both a mechanical and chemical bond with the substrate.

The mechanical bond is a very important factor in the long term performance of the CTI system. Unfortunately, skim coat applications that are done using "MagicTrowels" or squeegee’s do not achieve the same degree of mechanical bond as those done with pool trowels and are therefore at greater risk of failure.

With that said, it is CTI’s position that it is always better to hand trowel skim coat applications
