Taping knife Proline 31185 — drywall joint knife, 1 pc

The Proline 31185 taping knife is a drywall joint knife designed for applying joint compound, embedding tape and smoothing seams on plasterboard and other drywall surfaces. Supplied as a single unit, it combines a polished blade with high resilience to bending and a two-component anti-slip TPR handle for controlled use during wall and ceiling finishing, patching and repair tasks.

Advantages

The polished blade minimizes compound sticking and allows consistent feathering at edges. High blade resilience ensures the knife keeps its shape during repeated pressure and prevents unwanted bending while applying or smoothing material. The two-component anti-slip TPR handle improves grip comfort and reduces slipping when working with wet compound or in elevated positions. The tool’s construction supports both professional workloads and occasional DIY projects where precision is required.

Suitable for

• Applying joint compound to seams between gypsum boards
• Embedding joint tape on internal corners and flat joints
• Smoothing and feathering compound on walls and ceilings
• Small patching and repair jobs on plasterboard surfaces

Key specifications

• Blade finish: polished for reduced material adhesion
• Blade characteristic: high resilience to bending
• Handle: two-component anti-slip thermoplastic rubber (TPR)
• Pack quantity: single-piece pack

How to use

Hold the taping knife by the TPR handle and apply a thin, even layer of joint compound along the seam. Use steady pressure to embed tape and smooth the compound, working from the center of the seam outward to feather edges. For successive layers, allow the previous layer to dry according to the compound manufacturer’s instructions, then sand lightly if needed before applying the next coat. Clean the blade with water and a non-abrasive cloth immediately after use to maintain the polished finish.

Usage recommendations

For best results, use the taping knife with joint compounds and tapes suited to gypsum board systems. Select a knife width appropriate to the joint size and the stage of finishing: narrower for initial taping and wider for final smoothing and feathering. Store the tool dry and avoid prolonged exposure of the blade to corrosive substances to preserve resilience and polish.
