When removing a tile floor, you may want to reuse some of the tiles. You may also want to completely renovate the flooring and put new tiles down.
However, one of the issues with removing a tile floor is that some of the adhesive will be left.
Removing this adhesive can be incredibly difficult if you don’t know how to do it. It can even ruin your subfloor if it isn’t done properly.
Removing Glue From a Tile Floor: Basic Idea
There are a few different techniques for removing glue from a tile floor. They include:
- Use a solvent
- Chisel it off with a scraper
- Soak it in water
- Use a store-bought remover
What Kind of Glue Will Be On a Tile Floor?
Depending on the type of tile, there will be different kinds of glue that were used to adhere it.
Most of the time, you will be dealing with thinset mortar when removing tiles.
Thinset mortar is a cement product that is meant to harden over time. This is because you need to make sure that water doesn’t get under the tiles.
Sometimes, tile mastic is used to stick tiles to floors.
Usually, this adhesive is used on smaller tiles that are affixed to walls. However, in some dry rooms or areas, this will also be used on floor tiles.
For tile adhesive and tile mastic, solvents are going to be your best bet for removing them.
Solvents like mineral spirits and paint thinner will cut through the adhesive and thin it out. From there, you should be able to simply wipe the adhesive away.
When working with solvents, you should always make sure you are working in a well-ventilated area.
Chisel it Off
If you are dealing with thinset mortar, it will need to be chiseled off.
Thinset mortar is very hard and will be quite brittle. You should be able to pry the tiles up using a pry bar.
After the tiles are up, you may notice that the mortar has come up in big chunks. This will need to be chiseled off carefully if you wish to retain the tiles.
Be as careful as you can when removing the thinset. Applying too much pressure can damage the tile or the floor itself.
If you are working specifically with tile mastic, you can use water to remove it.
Tile mastic is not waterproof and will in fact dissolve when it comes into contact with moisture.
To remove tile mastic from tiles or the floor, first soak some rags in water. Then, lay the rags over the floor or the tiles.
There are many specifically designed tile adhesive removers that you can buy.
Using these removers can be one of the most efficient ways to get glue off a tile floor.
Many adhesive removers contain volatile organic compounds. Because of this, you will want to make sure you are working in a well-ventilated area.
