How to Remove Old Thinset from Concrete Floor Without Removing It

Removing old thinset from a concrete floor can be a daunting task, especially if you don't want to remove the floor itself. However, there are several methods that can be used to remove thinset without damaging the underlying concrete.

1. Mechanical Removal

Mechanical removal involves using tools to scrape or grind away the thinset. This is the most effective method, but it can also be the most time-consuming and labor-intensive.

Tools that can be used for mechanical removal include:

Floor scrapers
Grinders
Chisels
Hammers

2. Chemical Removal

Chemical removal involves using a solvent to dissolve the thinset. This is a less labor-intensive method than mechanical removal, but it can be more hazardous. The solvent used will depend on the type of thinset that was used.

Safety precautions should be taken when using chemical removal methods, including:

Wearing gloves and eye protection
Working in a well-ventilated area
Following the manufacturer's instructions carefully

3. Acid Washing

Acid washing is a method of removing thinset using a muriatic acid solution. This method is effective, but it can also be dangerous. Muriatic acid is a strong acid that can cause burns and other injuries.

Safety precautions should be taken when using acid washing methods, including:

Wearing gloves, eye protection, and a respirator
Working in a well-ventilated area
Following the manufacturer's instructions carefully

4. Steam Cleaning

Steam cleaning is a method of removing thinset using a high-pressure steam cleaner. This method is effective, but it can also be expensive. Steam cleaning can also damage certain types of concrete floors.
