Which Thinset For 12×24 Porcelain Tile [Explained]

Deciding between an adhesive for your new tile can be a real headache! But if you’re already leaning towards installing porcelain tile with thinset. Then, you’re off to a good start. 

Thinking about which thinset for 12×24 porcelain tile?

For this, firstly you’ve to pick a color that best suits your needs. After that, you can decide between two thinset. One is polymer modified and the other is latex modified. And finally, you can make the thinset mixture for your project!

Want to know more about how to do it? Then my friend, follow along and we’ll take you through it step by step. 

What Kind Of Thinset Should I Use For A Porcelain Tile?

Now, there’s a lot of options to decide before choosing the thinset. You have to pick a color, decide between the type and finally choose one! 

This is because one poor decision can cause a time-consuming repair. This might include retiling. Much like how one faulty outlet can possibly damage many outlets at once. Thus, you’ll have to fix all of them. 

Without any delay, let’s move along. 

What Color Thinset To Choose

You must be wondering, “Wait what? There are colors?’. Well yes, there is. You have two options to choose from.

Thinset comes in white and gray. We have these two options for a reason, let’s check it out!

The white thinset is used to install translucent tiles. For example, white or yellow marble, or a glass tile. Basically, any light-colored or see-through tile. Otherwise, the color is going to be visible.

The gray one is used for tiles that have a darker shade. The dark thinset will match with the grout as well as the tile. This will give your floor a neat finish.

Why Modified And Not Unmodified Thinset?

Well, this is a question that bamboozles even the best installers. So, how do we decide? Don’t fret, let me take you through it.

What is unmodified thinset made of? Basically, it consists of cement, sand, and a water retention agent. These are for tiles with a high absorbent rate.

Let’s see what modified thinset is made of. Unlike the unmodified formula, the modified version has additional retention products. These might be latex or polymer. 

Basically what they do is, increase the bond and strength of the thinset. This helps better stick the tile to the floor. Because you don’t want your tile to crack or fall like a loose bed slat.

Clearly, the modified version looks like a better option. And guess what you’re right. 

Now, let’s look at the reason why this is the better choice.

Which Type To Use

For the installation, it is recommended to use a latex or polymer modified thinset. 

Now, you must be wondering why only these types are recommended? Why not use the normal thinset?

Well, each tile has a different adhesive requirement. Accordingly, different thinset have different amounts of latex. This latex in the mix will cause variation in the adhesive strength.

For example, on a ceramic tile, you don’t need a lot of latex. This is because it has a clay body. And thus will absorb the regular thinset and bond well. 

A porcelain tile is non-porous. Therefore we need a lot more latex for it to bond. 

It can be said that latex or polymer thinset will be the best choice. This will increase the bond and strength. Thus it significantly reduces the chance of cracks in the tile. This is just like how we attach brick and siding with flashing

We’re finally clear on what type and color to use! Here we have some thinset options to choose from:

Now, you know your choice. Let’s move on to the next part, shall we?

How To Mix The Thinset?

Before getting into the mixing, put on your protective gear. Make sure to put on your gloves, eye protectors, and respirator.

Pro Tip: It’s best to mix a small portion at a time. Otherwise, your thinset might harden.

Before mixing it, here’s a list of essentials that you’re going to need:

  • Large Bucket
  • Thinset
  • Measuring Cup

Now, we’re all set, let’s get started.

For the mixture, you’ll first have to start with a clean bucket. Add a quart of water into the bucket using the measuring cup. Then slowly add 8-9 pounds of thinset. Make sure the consistency isn’t too thick or runny.

Pro Tip: To find the amount of thinset, divide the square footage of your room by 95. Then round up the number to the next whole number.

For example, a 15×10 room is 150 square feet. Dividing it by 95 gives 1.58. Therefore you’ll need two bags of 50-pound thinset.

After that continue mixing it for about 3-5 minutes. Then, let it sit for 10 minutes. This allows the chemical reaction between the thinset and water to start. 

After 10 minutes, mix again. Do this for a couple of minutes.

Caution: Don’t add more water after the slacking period. This is because it’ll make the thinset weaker and destroy its integrity.

Now that we have our thinset ready, you can install your tile! Take your trowel and spacers to start placing!

That’s all from us!

Hope this helped you decide which thinset to choose for your porcelain tile.


Question: Can Thinset be used for leveling?
Answer: Yepp. Thinset can be used to level out any uneven cement floor. This is because it is a type of cement used as an adhesive. Therefore, this could be used for leveling without actually installing the tile.

Question: Can you use too much thinset?
Answer: This is definitely a possibility. Too much thinset will cause an uneven surface. Moreover, it can also result in costly clean-ups. Not to mention the added hours it will spring to the project.

Question: How do you remove dried Thinset from porcelain tile?
Answer: You need to wash the tiles thoroughly. Take a warm bucket of water and add with dish soap and granulated sugar. Now, apply the mixture in the areas and scrub it gently.

Bottom Line

That’s all for today! Well, you know now which is the thinset for 12×24 porcelain tile. How did your DIY project go?
