Purdy Premium Stiff Putty Knife - 1.5 Inch

The Purdy Premium Stiff Putty Knife 1.5 Inch is a rigid filling and scraping knife built for controlled, precise prep work. Unlike Purdy's Flex Carbon Steel range, this Premium Stiff knife has a firm, unyielding blade that holds its shape under pressure, giving you tight, direct control when you are pressing filler into a hole or scraping old material off a hard, flat surface. The narrow 1.5 inch blade width makes it the natural choice for small holes, nail holes, hairline cracks and detail work in corners and tight spaces where a wider blade would be clumsy.

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
• 1.5 inch blade width suited to small holes and detail work

How to Use

Filling: Clean dust and loose debris from the hole or crack first. Scoop a small amount of filler onto the blade, then press it firmly into the hole at an angle using the stiff blade to pack the filler in tightly. Slightly overfill the area, 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 short, controlled strokes to lift 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 small holes 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 1.5 inch width over a wider blade?
The narrow 1.5 inch blade is easier to control in corners, around fixtures and on small nail holes, where a wider blade would cover too much area and be harder to manage precisely.

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.
