How to Select the Right Notch Trowel for Flooring Adhesives

The right adhesive can only perform if it’s applied correctly. And that starts with the right trowel. Using the wrong notch size or type often leads to uneven coverage, bond failures, and costly callbacks.

For Canadian building material distributors, educating contractors about proper trowel selection—and stocking the right tools—adds significant value. With Buildix ERP, you can track trowel inventory alongside adhesives and deliver technical support that sets your business apart.

Why Trowel Selection Matters

Each flooring adhesive has specific spread rates to achieve optimal bond strength. The trowel’s notch size and shape directly affect:

Adhesive Coverage: Ensuring enough material is applied to bond securely.

Bond Integrity: Preventing hollow spots and weak areas.

Material Performance: Allowing for expansion and contraction without failure.

Key Factors in Choosing a Notch Trowel

1. Adhesive Type

Thicker adhesives (urethane, epoxies): Require larger notches for proper spread.

Thinner adhesives (acrylic, pressure-sensitive): Pair with fine-notched trowels for uniform application.

2. Flooring Material

Resilient Flooring (LVT, sheet vinyl): Smaller notches for thin, even coverage.

Wood Flooring: Larger notches accommodate material irregularities and ensure full contact.

Tile and Stone: Deep notches help achieve consistent coverage on uneven substrates.

3. Subfloor Condition

Uneven or porous subfloors may require trowels that deliver more adhesive.

Common Trowel Notch Types

Square-Notch Trowels: Best for most wood and resilient adhesives.

V-Notch Trowels: Ideal for thin spreads on smooth surfaces.

U-Notch Trowels: Perfect for tile adhesives requiring deeper ridges.
