Thinset usually works as a great adhesive. You can apply it to fix the tiles in a place. Any hard surface is suitable for the application of the thinset.
Well, preparing a proper thinset is a challenge here as the consistency of the thinset mixture decides how beautifully the tiles would sit on the surface.
Following the below tips and information regarding thinset and if the thinset sticks to metal or not would give you the proper direction to apply the thinset.
Does thinset stick to metal?
Thinset can stick to the metal. Thinset is appropriate for any type of hard surface. Applying thinset on the metal surface can adhere tiles to the metal. You can also try scuffing off the metal to create a concrete-like surface on the metal. A proper thinset mixture would do the rest work.

Thinset has its own purpose to serve. It mainly works as a suitable adhesive between the tile and surface. You can put tiles on concrete surfaces, and metal surfaces while using the thinset as the adhesive. Using grout is also a good choice.
Thinset might not give similar adhesion to every single metal surface.
Thinset to aluminum:
Aluminium generally has a smooth surface. The smooth surface is also suitable for the thinset. Mainly cement-like thinset would work with aluminum. Aluminum in that case can give adhesion to the tiles.
While applying thinset, the surface should be cleaned properly. Any grease or dirt left on the surface would cause not to let the thinset stick perfectly. Better to make a proper mixture of the thinset and apply it over the metal surface. Later, put tiles on the thinset.
Too much water in the thinset can lead to failure of sticking the tiles. You can also use grout instead of thinset.
Thinset to stainless steel:
Thinset can easily adhere to stainless steel. Stainless steels have a hard surface. Though the surface is smooth, you can sand it to get a rough one. Well, scraping off the stainless steel might take a huge time.
Rather go for applying Thinset. Thinset can also work as mortar. Moreover, it would let the tile sit on the surface of the stainless steel. Stainless steel does not really have a history with Thinset. Yet, trying would get you a way out.
Thinset to fireplace metal:
Fireplace metals are suitable for the application of the thinset. Fireplace usually does have a lot of grease. You need to pull the grease and any kind of dirt from the surface of the metal.
As thinset can set tile on any metal surface, it can do the same for the fireplace metal.
Rather, butter the beneath side of the tile as well. As a result, it will put a good adhesion in between the thinset and the tile so that the tile can set in place. As long as you follow proper procedure, you can put thinset to fireplace metal.
Will thinset stick to the metal corner bead?
Yes, thinset sticks to the metal corner bead. The corner beads are placed in the case of door joints. If you want to tile up the whole wall, you might need to put the corner bead. You can also use tape. In the case of metal corner beads, you need to install them before tiling.
You can use thinset to metal corner beads as well to attach the tiles. Apart from that, mud is also used over the metal corner bead to provide good adhesion. You can put any of these two.
Will modified thinset stick to metal?
Yes, the modified thinset would stick to the metal. Both modified and unmodified thinset are suitable for thinset. Most metals consist of a smooth surface. Meanwhile, thinset or mortar should be put on a rough surface to provide better adhesion to the tiles.
As a result, the modified thinset would stick to metal and tile.
As metals do not have a rough surface, it is better if you can put modified thinset rather than non-modified thinset. Modified thinset contains latex which is proper for giving adhesion between the tile and the surface of the metal.
Latex mortars can also be chosen for the same purpose.
Can you use thinset on metal?
Yes, you can definitely use Thinset on the metal. The Thinset is mainly applied to tough and rough surfaces. Through the surfaces, the Thinset can provide adhesion between the tiles and the surface. You can also use mortar or mud for adhesion.
The reasons for putting the thin-set, particularly on the metal are given below.
Provide adhesion:
Usually, the thinset needs a rigid surface. A rough surface is preferable. Though you need to smoothen it out by sanding. Meanwhile, metal already has a smooth surface. It does not even need sanding. Still, you can scrap the metal off if you want.
Thinset provides adhesion in between the surface of the concrete or metal to the tile. The adhesion is necessary as the tile will not be in place unless the adhesive adheres to the tile. Many might use a mortar and can work it out.
However, the Thinset can be absorbed into the metal. As a result, better adhesion is provided. As long as the surface can hold the tile through the thinset mixture, thinset can be applied.
What type of thinset to use on metal?
Most thinset can be used on the metal. Thinset works as an adhesive on the metal to adhere to the tiles. Common types of thinset are modified thinset, non-modified thinset, and epoxy mortar. All of these can be used on metal. Modified adheres smoothly as it contains latex.
Well, latex mortar is also suitable for metal. All these would provide a proper adhesion of the surface to the tiles. To proceed you need to make an appropriate mixture of thinset. The consistency should be appropriate for the adhesion.
Or else, no matter what thinset you use, the tiles will not stick to the thinset and not even the thinset to the surface.
How to apply thinset on metal?
Thinset can be applied to the metal even though the metal has a smooth surface. You should prepare the surface and thinset properly before proceeding. Otherwise, the tiles will not get along with the thinset and even the surface of the metal. Later the tiles can also fall off.
You can follow the below steps to do the proper process.
Clean the surface of the metal:
Cleaning the surface of the metal is a must here. Before applying thinset always do proper cleaning of the surface no matter what surface it has. Clean up all the grease and remove the dirt from the metal. Otherwise, the thinset would be unable to stick to the metal.
Apply the thinset:
After cleaning, you can proceed to apply the thinset to the metal. Prepare the thinset and use a trowel to spread the thinset on the metal. Make the thinset even by doing strokes with a trowel. Spread the thinset all over the metal in the same amount.
There should not be too much thinset on the metal. Otherwise, the thinset will spread and come out as an extra portion through the gap between the tiles. You would need to clean the tiles as well to not let the thinset dry on them.
Put tiles:
After spreading the thinset, put the tiles on the thinset. Let it dry for at least 1 day. After drying, you can put grout in between the spaces of the tiles. Finally, you can finish off your work after putting on grout.
Final thoughts:
Overall, thinset is able to stick to the metal. Thinset is placed between the tiles and the metal surface. It provides adhesion between the metal surface and the tiles. Moreover, it holds the tiles. If the thinset is not applied properly on the metal and tiles, the tiles can even fall off.
