4 Easy Ways on How To Remove Thinset

These are some of the most effective and easy ways to remove thinset from flooring and plywood.

1. Using Hammers And Chisel

Removing thinset by using a hammer and chisel is the easiest way to get rid of it, but it is a dusty task. So wear dusk masks and eye protection goggles to protect yourself from the fine pieces of thinset. Also, cover the things around the flooring with plastic so that the dust does not settle on them.

Now, tap with a hammer to break loose the bond between the thinset and the flooring. Make sure that you are not tapping too hard to damage the flooring. Keep tapping for around 20 to 30 seconds and you will notice that thinset has started breaking away from the flooring slowly.

Tap a few more times and thinset will disengage itself. Now, use a chisel to bring out the remaining thinset. Keep chisel at 45 degrees and apply pressure on it to pull out the remnant layer of the thinset. Keep on repeating this process until you peel off the entire layer of the thinset.

2. Using A Floor Buffer

Floor buffer is a machine which has a diamond disc cutter which is used to cut hard substances. A good quality floor buffer will cost you around $500 to $700 but the price is worth it. You can also rent the machine if it is available for rent around your home. It is advised that you should use a floor buffer carefully as the blade used in the machine is too sharp and can cause serious injuries.

You can also seek professional help if you don’t know how to operate the machine. You can go for wet grinding or dry grinding. Grinding will lead to a thick cloud of dust around the area of grinding, therefore, use dust masks to save yourself from fine particles. We admit that it is a time-consuming way to remove thinset, but you will get smooth flooring after the hard work.

After you are done with grinding, you will have to clean the things around as dust would settle on everything around the grinding area. You can use broomstick and dustpan to clean up the mess.

3. Using Hot Water

Soaking the thinset in hot water will produce cracks in it within 40 to 60 minutes of pouring the hot water on it. Ensure that the water is hot enough to crack the thinset and handle the hot water with utmost so as not to injure yourself.

For a more promising effect, you can add vinegar or citrus degreaser as it will help in pacing up the process. After the cracks have appeared on the thinset, use chisels or a floor scraper to get rid of the thinset.

4. Using A Chemical Mastic Remover

You can buy a chemical mastic remover from any online hardware store of physical shops. It will cost you around 100$ for a bucket which measures 5 gallons of chemical mastic remover. Prefer a mastic remover having citric or acetic acid rather than the other mastic removers as they are quite safe.

If you are going to remove thinset from wooden plywood, then prefer the products which are good to go with wooden material otherwise it can cause damage to the wooden material. After using a chemical mastic remover, you can scrape off the remaining thinset using a putty knife or floor scrapper.

Conclusion 

It is recommended that after removing the thinset, dispose it off as hazardous waste because it can cause environmental harm. Removing thinset is important because before installing flooring the surface must be clean and without any bumps.
