You don’t need a premixed tub for every tiny wall blemish. This quick-patch putty stirs together fast with pantry-style basics when you need a small dab of paste for a minor touch-up around the house (because of course the wall noticed guests were coming).
Making a small batch yourself costs very little compared to buying a full container of patching compound you may only open once. Using your own mix also lets you control the thickness by adding only enough water to make a paste, instead of dealing with a product that’s too stiff, too loose, or far more than you need.
You only need 3 materials for this project: salt, powdered starch, and water. The original method makes one small batch, and all you need to pull it together is a simple mixing container and something to apply the paste, such as a putty knife or similar small spreader.

How to Use Quick-Patch Putty
This simple paste works best for small, quick patch jobs when you only need a little putty and don’t want to open or buy a full container of patching product. Spread a thin layer into the spot you’re fixing and let it dry fully before deciding whether it needs another light application.
For larger holes, deeper damage, or areas that need a more durable repair, use a standard wall repair product instead. Commercial patch products are generally intended for cracks, dents, and holes in drywall or plaster, while deeper repairs often need layered application.
Safety Information
Mix and use this putty in a dry work area, and avoid creating or breathing loose powder dust while measuring the starch. Fine starch powders should be handled carefully and kept away from children’s faces because inhalation can cause breathing problems, a point also noted by DailyMed in consumer labeling for cornstarch powder.
If you’re patching a visible wall area, test a small spot first. This homemade mix is a quick fix, not a guaranteed match for every painted, papered, plaster, or textured surface.
Storage
Because this mixture contains water and the original method gives no preservative or long-term storage directions, it’s best to make only what you need for one repair. Keep the dry salt and powdered starch stored separately in a cool, dry place until you’re ready to mix another batch.
Estimated Cost
A small batch of Quick-Patch Putty costs only pennies to make, since it uses equal parts salt and powdered starch plus water. Comparable ready-made patching products usually cost several dollars per container, even when you only need a spoonful, so this is a handy budget option for very minor repairs.

Frequently Asked Questions about Quick-Patch Putty
It works best for very small patch jobs when you only need a little paste for a quick touch-up. Think minor blemishes, tiny dings, or a spot that needs a small fill, not a serious wall repair.
The original formula calls for powdered starch, so that’s the version to follow if you want to stay true to the project. If your powdered starch product is cornstarch-based, that fits the method, but I wouldn’t rewrite the ratio around a different starch without testing it first.
Add only enough water to make a paste. Go slowly so you can keep the mixture thick and spreadable instead of turning it runny.
It dries after application, but this article doesn’t claim a specific cure strength or finish. Treat it as a quick patching paste for light-duty use, not a guaranteed replacement for every commercial repair compound.
It’s better to mix only what you need. Since the method includes water but no preservative and gives no long-term storage directions, fresh batches make the most sense.
A small putty knife works well because it lets you press the paste into the spot and smooth the surface. For a tiny repair, any small spreader you already have on hand can do the job.
No. This is better for small quick fixes. Larger holes, deeper damage, or anything structural needs a proper patch material made for that kind of repair.
You’ll want the patch completely dry first. Since the original method doesn’t give paint-finish guidance, test a small area before painting a visible surface so you can see how it behaves with your wall finish.
Because sometimes you need a dab, not a tub. If you already have the materials, this quick mix saves money on tiny repairs and cuts down on leftover product you may never use again.
