To remove glue from a concrete floor, pour boiling water onto the surface and then scrape it off of the concrete. Finish by washing the floor.
Old carpet or other flooring products can leave glue on concrete floors that is often very difficult to remove. Run through the following steps to remove glue from a concrete floor.
- Scrape at the glue
- Soak the area in boiling water
- Apply a chemical adhesive remover (optional)
- Scrape off the glue
- Iron the glue
- Scrub the area
Carefully scrape at the glue to remove as many big chunks as possible. This leaves less glue to remove later on in the process.
Pour boiling water on top of the glue. Let the water soak in for a few minutes to soften the glue and make it easier to remove.
If the boiling water does not soften the glue, apply an adhesive removal product to the area. Let the product work into the glue for around 30 minutes.
Use a flooring razor scraper or a tile removal tool to scrape the glue off of the floor. Take care not to scratch the floor.
Place newspapers onto the glue and iron them with a hot iron. This causes the glue to stick to the newspapers. Keep working new sections of newspaper onto the glue until as much of it is removed as possible. Scrape away excess glue.
Scrub any remaining glue away with a mixture of hot water, ammonia and liquid detergent. Use a scouring pad to work away the rest of the glue.
