Scrapers are among the most underrated tools in a painter’s studio. A flat, flexible blade cleans dried paint off a glass palette in seconds, spreads gesso and modeling paste in smooth layers, scrapes back a muddy passage to start again and drags texture through wet paint.
For fine-art painters, the best scrapers are usually simple stainless steel putty knives in a few widths, a razor blade scraper for glass palettes and a plastic scraper for delicate surfaces. They are inexpensive, last for years and handle jobs that palette knives are too small or too delicate for.
When we checked Amazon listings for this page, almost all results were multi-tools and scrapers sold for house painting and drywall: 10-in-1 tools with hammer ends, nail pullers and roller cleaners. Those features are of little use to an artist. Two stainless steel putty knife sets in graded widths do suit studio work, so we feature them below, with an honest note that they are sold as drywall and putty knives.
Because these tools are cheap and nearly indestructible, a good set is one of the best-value purchases you can make for a studio.
The rest of this guide explains how artists use scrapers, which blade types suit which jobs and how to avoid damaging palettes and canvases.
Quick answer: For most painters, a set of stainless steel putty knives in several widths covers palette cleaning, gesso and texture work. The Rerdeim 5-Piece Putty Knife Set gives 1, 2, 3, 4 and 5 inch blades; the Beyotool 4-Piece Spackle Knife Set offers 2 to 5 inch blades with one-piece construction. Add a razor scraper for glass palettes and you have a complete scraping kit.
How Painters Use Scrapers
Cleaning palettes. Dried acrylic and oil peel off glass and acrylic palettes with a flat blade held at a low angle. Wider blades clean faster.
Spreading gesso. A wide flexible blade drags gesso into canvas weave and leaves a smooth, even layer. Several thin scraped coats, sanded lightly, give a surface like a panel.
Applying modeling paste and texture. Scrape on modeling paste or texture gel and drag, comb or stipple it before it sets.
Scraping back. Oil painters scrape a muddy or overworked passage back to a thin stain with a blade, then repaint. Acrylic painters can scrape wet paint to lighten an area.
Sgraffito and texture. The edge or corner of a scraper drags lines through wet paint to reveal layers underneath.
Mixing large batches. A wide blade mixes big piles of paint for backgrounds faster than a palette knife.
Choosing Blade Types by Job
Flexible stainless putty knives are the general-purpose choice for gesso, modeling paste and palette cleaning.
Stiff blades are better for scraping dried paint off palettes and tables, where flex wastes effort.
Razor scrapers are only for hard, flat surfaces such as glass palettes and windows.
Plastic scrapers and old credit cards are safe on acrylic palettes, soft plastics and delicate painted surfaces, and they make good disposable spreaders for texture gels.
Rubber shapers and silicone scrapers are handy for pushing paint around in abstract work and for wiping back without scratching.
Scraper, Palette Knife or Painting Knife?
Palette knives have a narrow blade, often with a cranked handle, for mixing paint on a palette. Painting knives are similar but with shaped, flexible blades for applying paint to canvas.
Scrapers and putty knives have wider, flat blades for spreading, cleaning and scraping. They complement palette knives rather than replacing them.

How to Clean a Palette With a Scraper
For glass palettes, a razor blade scraper is the fastest tool for dried oil and acrylic. Hold it at a low angle and push away from you. Never use razors on acrylic or plastic palettes, which scratch.
For clear acrylic and plastic palettes, use a plastic scraper or a stainless putty knife with lightly rounded corners. Let acrylic dry fully; it often peels off in a sheet.
For wooden oil palettes, scrape off excess paint with a putty knife, then wipe with a rag and a little oil.
Clean the scraper itself right away so paint does not harden on the blade.
Spreading Gesso With a Scraper
Pour a small pool of gesso onto the canvas or panel. Hold a wide blade at a low angle and drag it across, pressing gesso into the surface. Scrape off the excess.
Let it dry, sand lightly, then apply the next coat at 90 degrees to the first. Three to five thin scraped coats give a smooth, panel-like surface ideal for detailed work.
For a textured ground, leave some ridges instead of scraping smooth.
Texture and Sgraffito Techniques
Spread modeling paste with a wide blade, then drag the edge of a narrow blade to make lines, or tap the flat for stippled texture.
For sgraffito, paint a dark layer, let it dry, add a lighter wet layer and scrape through it with a blade corner or edge to reveal the dark beneath.
Notched edges can be filed into an old scraper to make a custom texture comb.
Scrapers in Abstract and Pour Painting
Abstract painters use wide blades like squeegees: load the edge with two or three colors and drag across the canvas in one pass for streaked, layered effects. Repeating the pull over dried layers builds depth.
In acrylic pouring, a scraper or putty knife cleans drips from canvas edges, levels paint pooled in corners and scrapes dried skins from cups and work surfaces.
Scrape-and-reveal techniques, where you apply wet paint over dried layers and drag it partly away, work well with a 3 or 4 inch blade.
Experiment with angle and pressure: a low angle and light pressure leaves more paint, a steep angle and firm pressure removes it.
Preparing Panels and Boards
Painters who work on wood or hardboard panels use scrapers at every stage. A wide blade spreads size or primer evenly, then several thin coats of gesso, each scraped smooth.
Between coats, sand lightly and wipe away dust. A smooth scraped gesso ground takes fine detail beautifully and is popular with realist and egg tempera painters.
For a toothier surface for pastel or acrylic, mix a little marble dust or pumice into gesso and scrape it on, leaving fine texture.
Scrapers also tidy panel edges: run a blade along the edge after gessoing to remove drips before they dry.
Building a Simple Scraping Kit
A practical studio kit includes three stainless putty knives (about 1, 3 and 5 inches), a razor scraper with spare blades for glass palettes, a plastic scraper for soft palettes and a couple of palette knives for mixing.
Keep blades in a jar or on a magnetic strip, away from brushes so edges do not damage bristles.
Label one blade for gesso only and another for paint, so dried gesso flakes never end up in a mix.
Caring for Scrapers and Staying Safe
Wipe blades clean immediately after use; dried acrylic on a blade creates ridges that drag. Stainless blades can be washed with soap and water and dried; carbon steel should be dried and lightly oiled.
Store razor scrapers with the blade retracted or covered. Scrape away from your body and fingers, and work on a stable surface.
Replace bent or nicked blades; a damaged edge scratches palettes and leaves lines in gesso.
Scraper Techniques for Acrylic Painters
Acrylic dries fast, which makes scrapers useful in a different way than in oil. Scrape wet acrylic thinly across a dried layer for a translucent, veil-like effect. Drag a blade loaded with thick acrylic for broken color that catches on canvas texture.
Use a narrow blade to lay down straight, crisp-edged bands of color for geometric work, then pull the blade away cleanly.
Combine scraping with a retarder or slow-drying medium if you want more time to manipulate paint before it sets.
Once acrylic has cured, scraping removes little; sand instead, or paint over.
Scrapers for Murals and Large Work
On large canvases and walls, a 4 or 5 inch blade lays in backgrounds and texture quickly. Some muralists use a squeegee or a wide plastic scraper to pull gradients across big areas.
Keep a damp rag nearby to wipe the blade between passes, so colors stay clean.
Scraping Back in Oil Painting
When a passage becomes muddy, scrape the wet paint off with a palette knife or putty knife, leaving a thin ghost of the image. This is a traditional technique that preserves the drawing while giving you a fresh start.
Wipe the scraped area lightly with a rag, then repaint with clean color.
Buying Guide: How to Choose Scrapers for Painting
Blade width
Narrow blades of 1 to 2 inches for small areas and texture; wide blades of 4 to 5 inches for gesso and palette cleaning.
A graded set gives flexibility.
Material
Stainless steel resists rust with water-based media. Carbon steel is stiffer but rusts unless dried and oiled.
Plastic scrapers are safest on soft palettes.
Flexibility
Flexible blades suit gesso and texture; stiffer blades suit scraping dried paint.
Feel the blade before use; flexibility varies.
Edges and corners
Sharp corners can snag canvas; round them slightly with sandpaper.
Keep one blade with sharp corners for sgraffito.
Handle
Rubberized handles are comfortable for long sessions.
One-piece construction is sturdier.
Skip the extras
Multi-tools with hammer ends and nail pullers add weight without helping artwork.
Choose simple, flat blades.

- Scraping gesso in thick coats that crack
FAQs
What do painters use scrapers for?
Cleaning palettes, spreading gesso and modeling paste, scraping back paint, sgraffito and texture, and mixing large batches of paint.
Can I use a putty knife as a palette knife?
For mixing large amounts and spreading, yes. For precise mixing and painting, a palette or painting knife is easier to control.
What is the best scraper for a glass palette?
A razor blade scraper held at a low angle removes dried paint quickly and safely from glass.
Will a metal scraper scratch my acrylic palette?
It can. Use a plastic scraper or a stainless knife with rounded corners, and let acrylic dry so it peels.
How do I apply gesso with a scraper?
Pour a small amount on the surface, drag it thinly with a wide blade at a low angle, let it dry, sand and repeat at right angles.
Stainless or carbon steel scrapers?
Stainless resists rust with water-based paint. Carbon steel is stiff and sharp but must be dried and oiled after use.
Final Recommendation
For most painters, a set of stainless steel putty knives is the best scraper investment. The Rerdeim 5-piece set covers every width from 1 to 5 inches, while the Beyotool 4-piece set offers sturdy one-piece blades from 2 to 5 inches.
Add a razor scraper for glass palettes and a small palette knife for detail work, and skip the hammer-ended multi-tools designed for drywall. Simple flat blades do everything an artist needs.
Start with one narrow and one wide blade, try them on palette cleaning and a gesso coat, and add widths as your work asks for them.
