Spackle vs. Putty: What’s the Difference?
Just fill it in and sand it smooth
Spackle and putty work well to fill in holes, cracks, or imperfections in drywall.
Putty is better suited to fixing damaged wood because it flexes with expansion and contraction.
Spackle dries quickly and works well in high-moisture areas.
If you have holes in your drywall, you’ll need to decide between spackle and putty when filling them in. Both materials serve the same purpose but have different properties that make them better suited to specific jobs. Rest assured, they’re both easy to use and cost-effective. Learn more about how to choose between spackle and putty in this guide.
Spackle vs. Putty: Key Differences
At first glance, spackle and putty appear nearly interchangeable for repairing holes in drywall and wood. Both spackle and putty cost about the same amount—around $7 for 8 ounces—making drywall repair costs for small jobs affordable. They’re both sandable, and you can paint over them.
But if you look a little closer, you’ll see key differences that can help you decide which one to use. When spackle dries, it’s rigid and stands up well to moisture. You won’t have to wait long for it to dry. Putty, on the other hand, will flex, making it a better choice for fixing smaller imperfections in wood and drywall. It takes longer to dry, affecting your decision if you’re on a tighter schedule.
If you have large holes in your drywall, neither one may be the best option, and you’ll likely need to use a patch kit or call a local drywall repair contractor to take on the job.
What Is Spackle?
Spackle is similar in composition to drywall and joint compound. It consists of gypsum dust mixed with calcium carbonate, quartz, vinyl, or titanium dioxide, forming a paste-like substance that fills holes and hardens quickly.
Spackle doesn’t flex once it’s dry and is moisture-resistant enough to use in bathrooms or other high-moisture environments. Once you paint over it, you likely won’t even know there was a hole. You can use lightweight spackle for smaller holes and heavy-duty spackle for larger holes.
| Pros | Cons |
|---|---|
| Dries quickly | Not suitable for areas that flex |
| Works well in high-moisture environments | Not the best choice to repair wood |
| Easy to apply | Not suitable for taping or finishing drywall |
Best for:
Homeowners who need to fill small- to medium-sized holes and cracks in drywall
Projects that need to move quickly
Bathrooms or other high-moisture environments
Pros of Spackle
Spackle is easy to work with if you need to patch a hole in drywall. To apply it, use a putty knife to smooth the spackle into the hole and even it out with the wall. After it dries, which only takes a few hours, sand it smooth and paint over it.
Spackle is white, but you can also find colored spackle for better visibility. Colored spackle dries white, so you know when you can start sanding and painting. Once spackle hardens, it stands up well to moisture, making it a good choice for fixing drywall in a bathroom or other area with high moisture levels.
Cons of Spackle
Spackle’s ability to dry quickly is often a plus, but it may not be the right choice if you need more time to work and smooth out a larger area. It’s very rigid after it dries, meaning it doesn’t flex. Therefore, it’s not the best choice for repairing wood that can expand and contract, and it doesn’t work for fixing large holes. It’s also unsuitable for taping drywall—that’s a job for joint compound.
What Is Putty?
Putty is an adhesive for filling in holes or cracks in drywall. It’s much thicker than spackle and flexes, so it’s ideal for repairing wood that will expand and contract. You can also use it as an adhesive to hang pictures or signs in areas where you don’t want nail or tack holes. Putty isn’t best for filling large holes, but it works well for filling in screw or nail holes. Then, you can sand the area until it’s flush with the wall and paint it to match.
| Pros | Cons |
|---|---|
| Suitable for wood and drywall | Requires longer dry times |
| Easy to apply | Not waterproof |
| Options for a variety of applications | May not match the original wood |
Best for:
DIYers fixing holes in material that may expand, contract, or flex
Small holes or cracks in drywall or wood
Mounting pictures or signs on the wall
Pros of Putty
Putty is reminiscent of Silly Putty and can fill small holes and cracks in drywall and wood. Putty flexes after it dries, so it’s ideal for filling nail holes in areas that expand or flex, such as baseboards, trim, or window sills. You can press putty into holes with a putty knife or twist and form it to repair deeper holes. The consistency of putty allows it to settle around nails or screw heads and any nooks and crannies.
After the putty is dry, you can sand and paint it to match the rest of the space. If you’re using it on wood, you can stain it to match the original surface.
Cons of Putty
Even though you can stain putty, it doesn’t absorb stain the same way natural wood will, so there may be a discrepancy in the appearance of the putty and the original wood. Not all putty is moisture resistant, so only use it in areas with low moisture levels. Putty takes quite a while to dry—between 24 and 48 hours—so if you’re in a hurry, this may not be the best option.
Spackle vs. Putty
Choosing between spackle and putty will depend on the material you’re working with. Overall, they achieve the same result of filling holes and patching small imperfections. But depending on the material you’re fixing and the appearance you’re going for, one of these products will work better than the other.
DIYability: Tie
Both spackle and putty provide a simple way to fill a hole or crack in drywall. Simply use a putty knife to put a little of the material into the hole you need to fill, scrape off any the excess, and smooth it out. Wait the recommended dry time—a few hours for spackle or 24 to 48 hours for putty—and you can sand and paint it to match the surrounding surface.
Appearance: Spackle
Both of these materials do the job of filling in holes and look great while doing it, especially because you’ll likely paint over them. Spackle has a slight advantage because it does a great job blending in with the original material after you sand and paint it. Putty, when used for stained wood, may not match the original wood even if you stain it the same color.
Price: Tie
Spackle and putty cost around $7 for 8 ounces. Because they’re so easy to use, you can save money by fixing the drywall yourself rather than hiring a pro, as long as the repair area is small. You’ll also need sandpaper and possibly paint or stain to finish the surface.
Repairing Wood: Putty
Wood expands and contracts with fluctuations in temperature and moisture. When spackle dries, it becomes rigid and won’t flex with the wood. However, putty is manufactured to flex, so when the wood moves, the putty won’t crack as easily as spackle would.
Durability: Tie
Whether spackle or putty is more durable depends on the material you’re repairing. They both work well on drywall unless it’s in a moist environment like a bathroom or kitchen. Spackle is more durable in these environments because it dries into a hard, rigid surface that won’t be affected by moisture. Putty is more durable on wood because it will flex with the contraction and expansion of the wood, making it less prone to cracking.
