Purdy Premium Stiff Putty Knife - 3 Inch

The Purdy Premium Stiff Putty Knife 3 Inch is a rigid filling and scraping knife built for covering larger areas quickly. Unlike Purdy's Flex Carbon Steel range, this Premium Stiff knife has a firm, unyielding blade that holds its shape under pressure, so you can apply even, consistent pressure across a wide area. The 3 inch blade width is the widest in the Premium Stiff range, making it the right choice for bigger holes, wider dents and larger areas of scraping where speed and coverage matter more than fine detail.

This knife is part of Purdy's range of professional decorating prep tools. Purdy is an American decorating brand and part of Sherwin-Williams, well known for paint brushes, rollers and the prep tools that get a surface ready before painting begins.

Features

• Full length rust resistant, stainless steel blade with a stiff, rigid temper
• Rubberised ergonomic grip to prevent slipping and increase comfort during extended use
• Nail set hammerhead end for tapping in proud or loose nails before filling
• 3 inch blade width suited to larger holes and wide area coverage

How to Use

Filling: Clean dust and loose debris from the hole or crack first. Load a generous amount of filler onto the wide blade, then press it firmly into the hole or gap using the stiff blade to pack the filler in tightly and spread it evenly across the wider area. Slightly overfill, since filler shrinks a little as it dries. Once fully dry, sand lightly flush with the surrounding surface.

Scraping: Hold the blade at roughly a 45 degree angle to the surface. Apply steady, even pressure and work in longer, controlled strokes to cover more ground while lifting old paint, wallpaper or dried filler without gouging the surface underneath. Use the flat face of the blade to clear away loosened debris once you are done.

FAQs

Should I choose the stiff blade or the flex blade?
Choose this stiff blade when you want firm control for filling and scraping flat, hard surfaces. Choose a Purdy Flex Carbon Steel knife instead when you need the blade to flex and follow an uneven or curved surface.

Why choose the 3 inch width over a narrower blade?
The wide 3 inch blade covers larger holes and dents in fewer passes, which saves time on bigger jobs, though a narrower 1.5 inch or 2 inch blade is easier to control in corners and small detail areas.

How do I clean this putty knife after use?
Wipe off wet filler with a damp cloth before it dries. If filler has dried onto the blade, soak it briefly in warm water, scrape the residue off with an old cloth, then dry the blade thoroughly to prevent rust.
