Liquid Nails is a solvent based synthetic rubber construction adhesive, used to form a long-lasting bond between two items. It’s widely used by tradespeople to the DIY types to adhere items to masonry surfaces such as signage, quickly and without needing to drill holes in the wall. It’s low cost and ease of application make it a popular choice. But just ask those who have tried to remove liquid nails from brick surfaces, it’s not an easy task to perform!

Removing liquid nails on brick walls after the removal of signage can be a difficult and time-consuming job.

Every factory, retail shop and professional practice has at least one sign. These signs are put up with various means of affixing them to the walls, with little thought to how the wall is going to look when they are removed. This example is one of the most common forms of affixing letters to a wall – sticking them on with liquid nails. When the sign is removed some of the liquid nails remains on the wall and for many of our clients is almost impossible to remove.

The reason why it’s so hard to remove liquid nails from brick and other masonry surfaces is that it’s inert to chemicals when dry. Liquid nails is highly resistant to heat, making it difficult to dissolve. As chemicals, heat and high pressure won’t break it down; the only way to remove it is with physical force, which will stain the walls surface.

This becomes an issue for many business owners, as signage regularly changes when it becomes worn, or when a rebrand is conducted. If you’re relocating and handing back the keys to the landlord, these types of stains can become a nuisance.

The only way to handle this is to accept that there will be liquid nails stains once the object is removed, and plan to remove these stains without damaging the underlying surface.

Many will use common supermarket or hardware store cleaning products, however these often achieve more harm than good. Products such as bleach, ammonia and borax have high levels of alkalinity. Common household items such as toilet cleaner, vinegar and lemon juice have levels of acidity. Alkaline and acidic substances can have a harmful effect on masonry surfaces, leading to white powdery stains, erosion of the surface and damage to mortar.

Acetone products are another cleaning product which some people have attempted with varying results. However this has numerous risks for your health, including your respiratory system, nervous system, skin and eyes. It’s also highly flammable and harmful to the environment.

Many unscrupulous cleaners and tradespeople have no qualms about using harsh substances to remove these stains, displaying complete disregard to the consequences.

Our engineers have developed a system which safely breaks down the molecular structure of the adhesives such as liquid nails. Many people are surprised to learn that the stains don’t just sit above the surface; they are absorbed deep into the bricks. Once we have broken down the molecular structure we can draw the stains to the surface.

Our surface restoration vehicles carry water tanks with superheated boiler systems which we can use to neutralise the surface and restore it back to its original condition. As most business signs are several metres above the ground, we carry scaffolding and scissor lifts to ensure we can safely perform the task at hand.
