Removing Liquid Nails from brick can be a challenging task as it is a versatile construction adhesive that is chemically inert, highly resistant to heat, and unaffected by chemicals, heat, or pressure. While some people suggest using physical force to remove it, this method can risk staining or damaging the wall. Others have suggested using supermarket or hardware store cleaning products such as acetone, bleach, ammonia, borax, toilet cleaners, vinegar, or lemon juice, but these can also negatively impact masonry and cause erosion or mortar damage. A few possible solutions include using a solvent to soften the adhesive, applying heat with a blow dryer or soldering iron, or using a product like Goof Off to soften the adhesive before scraping it off. For a hassle-free removal process, it may be best to reach out to professionals who can safely dismantle the adhesive's molecular structure and restore the surface to its pristine state.

What You'll Learn
Soften with heat
Softening liquid nails with heat is an effective way to remove the adhesive from brick. However, it is important to note that liquid nails have a high resistance to heat, so a significant amount of heat is required to soften the adhesive.
To soften liquid nails with heat, you can use a heat gun, blow dryer, or torch. When using a heat gun or blow dryer, ensure that the adhesive is heated above 140°F. This will soften the glue, allowing you to peel or scrape off most of it. Be cautious when applying heat, as excessive heat for prolonged periods can damage the brick.
Once the adhesive is softened, use a putty knife or a flat edge to scrape off as much of the glue as possible. You can also use a soldering iron to carefully melt and remove the adhesive. If you are unable to generate sufficient heat with a blow dryer, a more powerful heat source, such as a torch, may be necessary. However, use extreme caution when working with an open flame, and always prioritize safety.
After removing the bulk of the adhesive, you may find that some residue remains. In this case, you can use a solvent to remove the remaining traces of liquid nails from the brick. Additionally, you can use mineral spirits to wipe down the surface and eliminate any lingering residue.
While heat is an effective method for softening liquid nails, it may not be the only approach needed. Combining heat with other techniques, such as solvents or physical force, can often be the most successful strategy for removing liquid nails from brick.

Soak with petroleum jelly
Removing liquid nails from brick can be a cumbersome task as the adhesive penetrates deep into the bricks. One way to go about it is to soften the adhesive by soaking it with petroleum jelly.
To begin the process, apply a generous coating of petroleum jelly to the liquid nails. Allow the petroleum jelly to soak into the adhesive for at least 12 hours, but preferably 24 hours. The jelly will slowly soften the dried liquid nails during this time.
After the soaking period, use a putty knife to scrape off the softened adhesive. Work slowly and gently, applying only light pressure to avoid damaging the brick. If the adhesive does not come off easily, do not force it. Instead, reapply the petroleum jelly and let it soak for another three to four hours.
For the next step, use a hair dryer or blow dryer alongside the putty knife. Turn the hair dryer to its highest setting and direct the hot air onto the adhesive while scraping with the putty knife. This added heat will further soften the adhesive, making it easier to remove.
By following these steps, you can effectively remove liquid nails from brick using petroleum jelly. This method is a safer alternative to using a hammer and chisel, which can cause damage to the brick surface. With patience and repeated applications, you can successfully soften and scrape away the liquid nails adhesive.

Use mineral spirits
Mineral spirits can be used to remove Liquid Nails from brick. Mineral spirits are not recommended for tub surrounds, vinyl, plastic, painted surfaces, or varnished surfaces.
To start the removal process, coat the adhesive with mineral spirits. Leave the mineral spirits on the adhesive for at least 12 hours to a day. This will soften the adhesive. After the adhesive has been softened, scrape it off using a putty knife or a flat edge. Finally, wipe the surface with mineral spirits to remove any remaining residue.
It is important to refer to the product label, Technical Data Sheet (TDS), and Safety Data Sheet (SDS) for safety and detailed application instructions before using mineral spirits. These sheets will provide important information on the proper use and handling of the mineral spirits to ensure a safe and effective removal process.
It is worth noting that there are alternative methods to remove Liquid Nails from brick. One option is to use a hammer and chisel to physically remove the adhesive. Another method is to heat the adhesive above 140°F with an electric heat gun or blow dryer to soften it, and then scrape it off.

Try Goof Off
Removing liquid nails from brick can be a cumbersome task as the adhesive penetrates deep into the bricks, and once dried, it becomes chemically inert, rendering it impervious to most chemical removal methods.
Goof Off is a chemical product that can be used to remove liquid nails from brick. While it may be effective in removing the adhesive, it is important to note that it may cause discolouration on the brick. It is recommended to try Goof Off first on a small, inconspicuous area of the brick to test for any discolouration before applying it to the entire affected area.
To use Goof Off, follow the instructions on the product label. Typically, you would apply the product to a cloth or brush and then use it to scrub the affected area. Allow it to soak for some time, and then scrub or scrape the softened adhesive away.
It is important to work in a well-ventilated area when using Goof Off, as the fumes can be strong. Always refer to the product instructions and take the necessary safety precautions when handling any chemical product.
If you are concerned about potential discolouration or other adverse effects, it may be best to consult a professional or consider alternative removal methods, such as using a heat gun or blow dryer to soften the adhesive, or soaking it with petroleum jelly, mineral spirits, or a dedicated adhesive remover.

Physical force
Removing liquid nails from brick can be challenging because the adhesive penetrates deep into the porous structure of the brick, and it is highly resistant to heat and chemical breakdown. Due to these properties, physical force is often the only effective method of removal, although it does carry a risk of staining or otherwise damaging the brick.
One way to apply physical force to remove liquid nails is to use a combination of 80-grit sandpaper and a wire brush. This method requires careful application to avoid damaging the brick surface or discolouring it. It is important to keep the abrasive focused on the liquid nails and to work slowly to avoid smearing the adhesive across a larger area.
Another physical method is to use a hammer and chisel to chip away at the adhesive. This method also carries a risk of damaging the brick surface.
Before resorting to physical force, it may be worth trying to soften the liquid nails first. This can be done by heating the adhesive to above 140°F with an electric heat gun or blow dryer, or by soaking it with petroleum jelly, mineral spirits, or a dedicated adhesive remover for several hours or even days. However, it is important to note that mineral spirits and dedicated removers are not recommended for use on certain surfaces like tub surrounds, vinyl, plastic, painted, or varnished surfaces.
