After the removal of tiles or carpet, getting rid of the adhesive can be quite a daunting task, especially if it has been there for significant time. Concrete is a very harsh material and removing any kind of glue from it can be both tedious and time-consuming.
If you thought that it is impossible to get the glue out, all you need is proper tools and a willingness to carry out different methods to complete the job. Remember that you cannot carry out concrete grinding over the older floor without having a smooth and cleaned surface so be ready to follow a few simple tips.
Use Boiled Water
Always begin by using boiled water in a large pot as this is one of the most successful methods. As soon as the water reaches the boiling point, pour it on the glue and let it sit for some time. The heat from this water will help in softening the adhesives and they can easily be peeled off with a hand scraper. However, be careful and do not apply this method if there are any electrical outlets near the floor.
Scrap the Glue
This is by far the simplest but an effort-requiring way to remove the scraps of glue from the floor before initiating concrete grinding. A hand scraper which consists of a metal blade mounted on a pole or a handle is used while some of the fragments may require a blade scraper to be removed. A power scraper which is a large and wheeled machine can also be used to perform the job and it will make the task less tedious.
If pouring large amount of boiling water on the floor is not safe, you always have an option of using an iron. While you let the iron heat up, place a number of layers of newspapers on the floor. You can now run the iron over the newspapers and can easily remove the glue. Using the newspapers will prevent the glue from melting and getting stuck to the iron but this method will make the process longer than usual. This is ideal when the area for removing the glue is limited.
Despite all your efforts, you can still find some stubborn glue which must be removed before concrete grinding. Having apprehensions regarding such a product is justified and in such a situation, you can always use a solvent to dilute the solution. There are manufacturer’s directions given that must be followed while using the adhesive cleaner because of the strong chemicals being present in it.
After removing the glue, sand the floor and clean it thoroughly. It is now ready for concrete grinding because the floor is clean and smooth enough for polishing or for new installations. Even after trying all the methods, if you are still unable to clean the floor properly then it is better to let a professional handle the job for you.
