3 Best Solvents to Remove Liquid Nails from Concrete

Liquid Nails is a well-known brand of strong adhesive often used in construction and renovation projects.

Designed to hold surfaces together forever, it’s brilliant when you want strength, and downright infuriating when you need it gone.

Because the adhesive is so strong, removing it from surfaces like concrete or drywall can sometimes be challenging.

Removing a smear of hardened Liquid Nails from concrete is a bit like breaking up with someone who refuses to let go—stubborn, messy, and requiring the right strategy. But don’t worry, you don’t need to be a chemist or a demolition expert.

In this guide, we’ll walk through the best solvents to remove Liquid Nails from concrete, so you can restore your surface without losing your sanity—or your weekend.

Let’s get that concrete clean again without damaging the surface.

We’ll also discuss some of the potential dangers associated with removing this type of adhesive, so be sure to read on before getting started.

3 Best Solvents to Remove Liquid Nails from Concrete

Whether you spilled some during a renovation or you’re trying to get rid of a stubborn bead of adhesive left behind from a project long gone, selecting the best adhesive remover solvent for concrete will save you hours of unnecessary scraping.

And yes—while these methods are concrete-focused, some are also useful when removing Liquid Nails from drywall (with a lot more caution, of course).

Below are the 3 best solvents to remove that old liquid nails adhesive from concrete, along with a bit of technical insight into how they actually work:

1. Acetone

Acetone is a fast-evaporating, high-strength solvent commonly used for breaking down rubber-based and synthetic polymer adhesives—exactly the kind used in many Liquid Nails formulations.

It penetrates the adhesive layer and begins to soften the bond, making it easier to pry or scrape off.

Note: Acetone is powerful, so avoid contact with painted surfaces, plastics, or anything that can degrade under strong solvents.

2. Mineral Spirits (Petroleum Distillates)

Mineral spirits don’t outright dissolve Liquid Nails, but they do soften and swell the adhesive’s outer layer.

This is especially helpful when dealing with old Liquid Nails adhesive that has fully cured. With enough dwell time, the softened layer becomes flexible, allowing easier mechanical removal with a scraper or oscillating tool.

Best for: Concrete, masonry, and other non-porous surfaces.

Use sparingly: Excessive soaking of mineral spirits can cause minor surface darkening.

3. Commercial Construction Adhesive Removers

Some high-strength nail polish remover products contain acetone, but standard nail polish remover is not designed for construction adhesives.

Instead, look for commercial construction adhesive removers—specialty solvents engineered specifically to break down polyurethane, latex, and solvent-based adhesive chemistries.

Many of these products contain a blend of ketones and aromatic hydrocarbons tailored to target the chemical backbone of construction adhesives, helping them loosen Liquid Nails more efficiently than household solvents.

Before You Start: Safety & Testing are Important

• Spot-test first: Apply the solvent that dissolves liquid nails in a discreet area to check for discoloration.
• Ventilation is essential: These solvents release VOCs that shouldn’t be inhaled for long periods.
• Use protective gear: Gloves, eye protection, and a mask are recommended when getting rid of old Liquid Nails adhesive.

After the heavy-duty adhesive is removed from your concrete wall, wash the area with warm, soapy water to eliminate leftover solvent residue.

Will Vinegar Work to Remove Liquid Nails from Concrete?

Liquid Nails is a brand that offers several types of construction adhesives, and many of their products are compatible with concrete surfaces.

However, when it comes to removing dried-up liquid nails from your concrete walls, basement floors, and masonry, the effectiveness of vinegar (acetic acid) is very limited to slight.

Especially when dealing with the heavy-duty, solvent-based, or polyurethane-based construction adhesive formulas commonly used on concrete, vinegar is generally not an effective solvent.

That said, some sources suggest a paste of vinegar and baking soda may help with minor, thin residue on sensitive surfaces.

On porous concrete, however, its cleaning effect is minimal compared to the required force for scraping the adhesive.

Other simple ways to remove dried-up liquid nails from your concrete surfaces:

If you’re trying to soften the Liquid Nails Concrete & Mortar Repair Adhesive (before the actual removal process), here are a few additional products and tricks that might help:

1- Baby oil

Baby oil (which is a type of mineral oil) can be used as a softener for Liquid Nails adhesive, especially to help remove residue that is too hard to scrape off.

Since baby oil is meant for a baby’s delicate skin, it’s the safest way to loosen liquid nails, but be aware that it might not be the most efficient way for complete removal, especially if you have a big spill or the adhesive has already dried.

• Use a chisel, scraper, or stiff wire brush to remove as much of the large, hardened clumps of Liquid Nails as possible.
• Apply a generous layer of baby oil or petroleum jelly directly onto the remaining adhesive residue on the concrete.
• Let the oil sit and soak for at least an hour to allow the oil to penetrate the adhesive and soften the bond.
• Use a putty knife or an old credit card to scrape away the softened adhesive.
• Wipe the area clean with a dampened soft sponge or damp rag.

2- Petroleum jelly

Petroleum jelly is made of hydrocarbons that will penetrate, soften, and help break down certain adhesives, making them easier to remove from surfaces like walls.

However, for cured construction adhesive on masonry surfaces like concrete or bricks, this oil-based substance does not chemically dissolve the glue, but it only loosens its grip, making the mechanical removal (scraping) much easier.

So, it’s highly recommended as a softener but not as an adhesive remover.

Petroleum jelly will also work pretty well if you have Liquid Nails stuck on your hands, sensitive parts of your fingers, or other body parts. Just make sure not to use the scraper on your hands – but rinse them thoroughly with soap and water after you’re done.

3- Soap and water

Cured Liquid Nails is designed to be water-resistant and chemical-resistant. So, simple soapy water will not dissolve it, and its effectiveness is very limited for hardened Liquid Nails.

However, if you don’t have baby oil, a solution of soap and warm water can help in a quick clean-up. This means soap water is excellent for wiping away wet or uncured adhesive immediately after a spill on surfaces like drywall, wood, metal, and skin.

You can also use a mix of dish soap with warm water to create a soapy solution as a final clean-up of the concrete surface after you have scraped off the adhesive and used an oil or solvent to remove the residue.

Just apply it to the area with the liquid nails and let it sit for several hours before scrubbing with a scrub brush or towel.

Important Notes on Using Adhesive Remover Solvents on Concrete

While using heavy-duty adhesive remover solvents on concrete blocks, cinder blocks, cement foundations, or masonry (brick, stone, and mortar), keep in mind that all of these are porous and will absorb oil, which can leave a dark stain that is difficult to remove.

If you plan to paint, seal, or apply any coating to the surface later, do not use baby oil (or any oil) because the residue will prevent paint or sealant from adhering properly.

You must use a chemical solvent like mineral spirits, acetone, or a commercial adhesive remover, followed by a thorough cleaning process.

Thorough cleaning process, besides scraping, might need the heat (from the heat gun or hairdryer) if the glue has already dried and is stubborn to remove.

This will likely result in some cosmetic damage, especially on sensitive surfaces such as plastic, wood, and drywall, so you’ll need to repair it afterward.

If, however, the oil stain isn’t a concern (e.g., in a basement corner that will be covered), then baby oil is a gentler, less toxic alternative to start with.

Can You Use a Sander to Sand Construction Adhesive Off Concrete Surface?

Yes, you can use a sander to get rid of construction adhesive on concrete—but it should not be your first or smartest option.

Unlike drywall, concrete is far more forgiving, which means mechanical removal is possible.

But once Liquid Nails or any construction adhesive has fully cured, it becomes dense, rubbery, and remarkably stubborn. Trying to power through it with a sander alone can feel like convincing a mule to move—possible, but unnecessarily exhausting.

Sanding thick or old Liquid Nails adhesive directly on concrete will also tend to generate heat, clog the abrasive quickly, and create fine dust that spreads everywhere.

Plus, aggressive sanding can unintentionally grind the concrete surface itself, leaving shallow depressions or swirl marks you’ll later regret.

But if you still prefer a mechanical approach—or you’re dealing with thin residue after using a solvent—the right way to do it is to choose the right abrasive tool, combine it with the right solvent, and sand smart, not hard.

Here are some of the best sanding tools for removing adhesive from concrete:

1. Angle grinder with a diamond cup wheel

If you’re serious about removing cured adhesive, this is the real workhorse.

The diamond cup wheel cuts through adhesive and levels concrete without clogging. It maintains consistent abrasion across rubbery materials that would normally gum up sandpaper.

It’s perfect for large patches or thick ridges of adhesive, but make sure you keep the grinder moving to avoid creating low spots.

2. Random orbital sander with 40–60 grit sandpaper

A random orbital sander is gentler on walls but useful when you’ve already used a solvent to loosen Liquid Nails and only a thin film or smear remains on the concrete.

Choose 40–60 grit for initial removal, then step up to 80–120 grit for smoothing out the surface.

Remember that adhesive can still clog the pads quickly, so expect to replace discs frequently.

3. Floor sander if you’re working on a large concrete area

A drum sander or floor buffer with a carbide-grit disc can help if you’re renovating a large concrete slab with scattered adhesive spots.

These tools with rectangular sanding discs cover more area efficiently, while maintaining a flat profile across the entire surface.

The most efficient approach for removing tough, dried-out Liquid Nails is to combine the two methods.

This means using a solvent (like acetone or a commercial adhesive remover) to soften or partially dissolve the adhesive.

Then, using the sanding or grinding process only for the leftover residue. This minimizes dust, prevents damage to the concrete, and drastically reduces your effort.

The Bottom Line

When it comes to removing Liquid Nails from concrete, choosing the right solvent is half the battle.

Liquid Nails—especially old Liquid Nails adhesive—is designed to withstand moisture, pressure, and time, so getting it off concrete takes more than elbow grease.

You need a chemical agent strong enough to loosen Liquid Nails and dissolve its synthetic resins, without compromising the integrity of the concrete surface.

The method you decide to use will likely depend on what materials you have on hand and how much damage you’re willing to accept. Therefore, take the removal action quickly and do not allow the adhesive to dry and harden.
