## Long description

Proline 31191 is a single-piece taping knife designed for drywall joint work. It is intended for applying joint compound, embedding tape and smoothing plasterboard seams. The tool features a polished steel blade for consistent compound distribution and a two-component anti-slip handle for secure grip during repetitive finishing tasks.
Advantages
The polished blade surface reduces material sticking and allows even spreading of compound across seams. A two-component anti-slip handle improves control and reduces hand fatigue during prolonged use. The one-piece construction provides stability and straightforward cleaning after use.
Suitable for
Applying and smoothing joint compound on drywall seams
Embedding paper or fibreglass joint tape
Finishing and feathering plasterboard joints before sanding and painting
General interior renovation and repair tasks involving plaster or joint compounds
Key specifications
Blade finish: polished steel for reduced compound adhesion
Handle: two-component anti-slip material for improved grip
Construction: single-piece taping knife designed for durability and easy cleaning
Intended use: spreading, smoothing and tape embedding on plasterboard joints
How to use
Ensure the drywall surface is clean and free of loose debris. Load the blade with an appropriate amount of joint compound and apply along the joint with steady pressure to embed the tape and distribute the compound. Hold the knife at a shallow angle to feather edges and smooth excess material. Wipe the blade clean between passes to maintain an even finish and prevent buildup.
Usage recommendations
For consistent results, use the Proline 31191 with compatible joint compounds and replace or clean the blade regularly to avoid dried residue. Store in a dry place to prevent corrosion of the polished steel blade.
