Concrete flooring, like any other flooring option, is not immune to common flooring problems. In fact, concrete’s naturally porous structure—especially if not properly sealed—makes it prone to stubborn stains.
Take tar, for example. Tar is a sticky brown or black substance that forms from wood, petroleum, and coal through destructive distillation.
And unlike food and drink stains in general, removing tar from concrete is a laborious and time-consuming process. In fact, cleaning the substance will require more than just wipes and dry towels.
But the good news is that it is definitely possible to remove tar from concrete with the help of tar removal mixtures such as muriatic acid, solvents, and commercial solutions specifically formulated for tar.
A Step-by-Step Guide to Removing Tar from Concrete
Tar has always been considered a stain that is extremely difficult to remove, no matter the type of surface. However, it is even more difficult to remove on concrete flooring, as it requires a harsh compound.
As stated, removing tar from concrete is generally done in two ways: firstly by using an acid solution and secondly by using natural or pre-made solvents .
This way:
Method 1: Using an Acid Solution
Acid solutions such as muriatic acid are commonly used products by home and building owners to remove tar from concrete. It is used especially when the stained surface is very large or spreads from one area to another.
However, keep in mind that acid solutions are harsh and toxic and it is important to wear protective gear – like gloves and goggles – and clothing. You can also seek the help of a professional, though, especially if you are not familiar with such things. Materials you will needStep 1: Dilute the acidStep 2: Apply the solution to the tar-stained areaStep 3: Scrub the tar away using a stiff-bristled brushStep 4: Scrape off any remaining stainsStep 5: Add sealant
Method 2: Using a Solvent
While people typically use muriatic acid or other acid solutions to remove tar from concrete, some home and building owners also opt for solvents such as kerosene and natural minerals. Diesel, paint thinner, turps, and even xylene can also remove tar from concrete.
The only disadvantage of using such solvents is that they are very flammable. Therefore, professionals recommend using it only on small tar stains.
However, if you want to use less risky solvents, commercially formulated tar-removal solutions are a great option. For example, Prosoco’s SureKlean Asphalt and Tar Remover is a safe multi-purpose masonry cleaner. It does not contain methylene chloride which is harmful to the heart and liver and can cause skin and eye irritation upon prolonged contact.
To use it, simply apply your chosen solvent slowly to the tar-stained surface. The process is the same as you would apply the solution. Just be extra careful when using solvents as they are more risky to use than acids.
Method 3: Home Remedies
Acid solutions and solvents are often recommended for large and deep tar stains. Therefore, if the stain is small and has not penetrated the concrete completely, home remedies are effective.Vinegar and dishwashing liquidPeanut butterRubbing alcohol
