How to Mix Thinset: Things You Need to Know

Need to use that thinset now but don’t know how to mix it? Today, we will be teaching you how to mix thinset.

If your home is where your heart is, then you must take care of your home. Taking care of your home does not only mean you have to clean the bathroom and the kitchen.


You must also be equipped with basic knowledge on how to fix leaks, broken bulbs, and broken tiles.

What is a thinset

As for broken tiles and other things that need to be attached to surfaces, you’ll be needing thinset. However, for you to use thinset efficiently, you have to know how to mix thinset properly.

We will be listing down a step to step guide on how to mix thinset as well as important things you need to know about using thinset.

What is a thinset?

Again, thinset is used to attach tiles or any “stone” to cement or concrete surfaces. Thinset or thinset mortars are adhesives made from fine sand, cement and water-retaining agents like the alkyl.

It is usually in powder form when bought from the store. But then it is also important to know when it is best to use thinset.

Then you’re going to mix it with additives and water to turn it into the adhesive that it’s supposed to be.

However, aside from home repair and construction purposes, artists also make use of thinset for outdoor mosaics. Take note though that you still have to mix the thinset with other additives to maximize its adhesive power.

Things You Will Be Needing

Mixing thinset does not have to be as complicated. However, you will need several important things. Here are some of the essentials:

  • Thinset Mortar - of case, this is an essential.
  • Respirator - do not underestimate this. You will have to wear this to avoid inhaling any mortar dust.
  • Mixing bucket - any makeshift bucket would do as long as you can mix all the additives and the thinset without spilling.
  • Water - or you can also use an acrylic additive to enhance the adhesive power and properties of the thinset.
  • Margin trowell - this will be used to smooth hard to reach corners and even out the applied thinset mortar.
  • Drill with mortar mixing paddle - similar to a handheld baking blender, this will make mixing thinset easier for you. However, this can be optional if you want to mix thinset manually instead.

The Procedure

Step 1: Prepare your materials.

Prepare all the materials first to make sure you don’t stall on mixing the thinset. This is so you minimize the mortar dust that might come from your mix.

Remember, thinset mortar is made from cement and fine sand so it might harden or dry up if not mixed right away.

You might also want to suit up to avoid staining your clothes or shoes. Don’t forget to wear your respirator, especially if you have breathing problems.

Ensure that your workplace is apt for the job as well. It can get very messy so make sure you do it in a garage or lawn.

Or if you want to do it inside the house, you can use old newspapers to cover the floor.

Step 2: Balance the amount of water and thinset mortar.

In a large mixing bucket, pour the water first. This is to minimize the amount of dust. Next, estimate the amount of thinset you will be needing and pour it into the water. Make sure you only make enough mixture for the job. No more, no less.

Any excess thinset mortar “saved up” for next usage might not be as effective anymore.

Should you feel the need to speed up the mixing process, you can use the drill with mortar mixing paddle at low speed. This will help keep air from being trapped in the mortar.

Remember, more air trapped in the mortar means weaker bond and weaker adhesive power. That is what you must avoid.

Step 3: Get the consistency right and let the additives do their job.

You must get the right consistency or else the thinset mortar won’t be as effective. Feel free to add more water or powder just to get the right consistency.

Try getting some of the mortar mixtures with your trowel. It should be similar to a very thick sandwich spread or a thick peanut butter.

Get the consistency right and let the additives do their job

If it doesn’t drip but can still be shaken off from the trowel, then that’s a perfect consistency.

Finally, let the mixture rest first for a good 10 minutes before you use it. This will give the additives enough time to work their way into the mixture. This process is also known as slaking. After the 10 minutes, give it one more stir, and you’re ready to go.

Wrapping Things Up

The thinset mortar is an efficient adhesive. However, it has its limitations.that is why to maximize its effectiveness, you must know how to mix it and use it properly. Know what are the things you can only use it for. Find the right additives for it.

But most importantly, make sure you make just the right amount of thinset mortar for whatever you will be doing.

Again, any excess saved up for the next usage won’t be as effective anymore. This is because air will inevitably become trapped in the mixture if you store it for too long.
