A notched squeegee is a flat application tool with V-shaped or square notches cut into its edge, used to spread self-leveling epoxy, polyaspartic, and urethane coatings at a controlled, even mil thickness.
Understanding Notched Squeegees in Floor Coating Application
Rather than pushing coating around like a standard flat squeegee, a notched squeegee is dragged across the poured material, leaving behind a wet film whose thickness is set by the size of the notches. It’s the standard tool for laying down consistent, self-leveling coating systems across large floor areas.
How Notch Size Controls Mil Thickness
Notch depth is chosen based on the target dry film thickness for the system being installed: larger notches lay down more material per pass. Installers pick the notch size from the manufacturer’s coverage-rate recommendations rather than eyeballing it, since laying down too little material leads to thin spots and too much wastes product and slows cure.
Notched Squeegee vs. Gauge Rake
A gauge rake is a similar tool with adjustable, wheeled legs used for the same purpose on larger commercial pours, letting installers dial in mil thickness precisely and move faster over big floor areas. Notched squeegees are more common on smaller residential and light commercial jobs.
Application Tips
Pour the coating in a controlled ribbon ahead of the squeegee rather than a single pile, and work in overlapping passes while the material is still self-leveling so lines from the notches flow out before the coating starts to set.
