Q: What material conditions is the 18-inch × 3/8-inch notch size squeegee best suited for?
A: A 3/8-inch (≈ 0.375 in) V-notch is designed for moderate to thicker coatings, providing greater deposit depth of around 35–45 mils of wet film thickness under optimal conditions.
Q: Why choose a gray EPDM rubber blade for this tool rather than a different rubber compound?
A: EPDM offers excellent resistance to solvents, oils and UV exposure, plus the gray non-marking finish helps avoid unwanted discoloration on light materials or clean surfaces.
Q: How can I tell when the squeegee blade needs to be replaced to maintain coating application quality?
A: Signs include rounding of the notch teeth, uneven ridge formation, increased coverage per gallon, or noticeable drag rather than a clean cut — indicating loss of notch definition.
Q: What best practices should I follow when using a large 18-inch notched squeegee to apply coatings on a jobsite?
A: Ensure the substrate is clean and properly prepared, maintain consistent angle and pressure, follow with a back-roll or leveling pass to remove high spots or air pockets, and match travel speed to material viscosity and notch size for uniform film thickness.
