About Putty Knives

Putty knives are essential hand tools for applying, spreading, and smoothing putty, filler, sealant, and other similar materials. Featuring a flat, flexible blade attached to a comfortable handle, these versatile tools are indispensable for painters, decorators, glaziers, and anyone undertaking window repairs or surface preparation work. MyToolShed.co.uk stocks a comprehensive range of putty knives from trusted brands including Faithfull, Purdy, Stanley, RST, and Draper, catering to both professional tradespeople and DIY enthusiasts.

Available in both stiff and flexible blade configurations, putty knives vary in width and blade rigidity to suit different applications. Premium models feature ergonomic soft-grip handles for extended use, whilst professional-grade options offer superior blade retention and longevity. Whether you're glazing windows, filling cracks, or preparing surfaces for decoration, the right putty knife makes all the difference to finish quality and working efficiency.

Applications

• Painters and Decorators: Filling nail holes, cracks, and imperfections before painting; applying flexible fillers to walls and ceilings
• Glaziers: Setting window panes with putty; repairing and replacing glazing compound
• Window Fitters: Installing and maintaining traditional timber window frames with linseed oil putty
• General Building Maintenance: Surface preparation, smoothing joint compound, and applying sealants
• DIY Enthusiasts: Home decoration projects, furniture restoration, and general repair work
• Joiners and Carpenters: Filling screw holes and gaps in timber work before finishing

Choosing The Right Putty Knives

Blade Flexibility: Flexible blades conform to uneven surfaces and are ideal for spreading compound smoothly, whilst stiff blades provide better control when applying traditional putty to window frames or working with heavier materials.

Blade Width: Narrow blades (25-50mm) suit detailed work and tight spaces, whilst wider blades (75-100mm) cover larger areas more efficiently. MyToolShed.co.uk offers various widths to match your specific requirements.

Handle Design: Soft-grip handles reduce hand fatigue during prolonged use and provide better control in damp conditions. Professional models feature ergonomically designed handles that balance comfort with precision.

Blade Material: High-carbon steel blades offer excellent durability and maintain their edge, whilst stainless steel options resist corrosion when working with water-based products. Premium putty knives from brands like Purdy and Faithfull feature rust-resistant blades for extended service life.

Brand Quality: Established manufacturers provide consistent performance and blade-to-handle integrity that withstands the rigours of professional use.

Frequently Asked Questions

What's the difference between a putty knife and a filling knife?

Whilst similar in appearance, putty knives typically have stiffer blades designed for applying traditional glazing putty, whereas filling knives feature more flexible blades suited to spreading joint compound and decorating fillers. Many professionals keep both types for different tasks.

How do I maintain my putty knife?

Clean the blade immediately after use with white spirit or appropriate solvent before material hardens. Dry thoroughly and apply a light oil coating to prevent rust. Store in a dry location and periodically check that the blade remains firmly attached to the handle.

Can I use a putty knife for scraping?

Whilst putty knives can remove loose paint or old putty, dedicated scraping tools are better suited for heavy-duty removal work. Using a putty knife for aggressive scraping may damage the blade or compromise its flexibility for spreading applications.
