Thinset For Shower Walls Buying Guide

Thinset For Shower Walls Buying Guide

1. Choose The Right Type

There are primarily two types of thinsets in terms of manufacturing, that is unmodified and modified thinset.

In terms of application or usage, we can also divide thinsets into two types, that is premixed thinset and unmixed thinset. Also, there are hybrid thinsets like LFT thinsets, epoxy thinsets, etc.

Choose the type that suits your purpose. For example, a modified thinset is a better choice than an unmodified one if you are using thinset for ceramic tile on concrete bases.

2. Water-Resistance

Tiles can be damaged in many ways due to being in constant contact with water. You can have issues like mold buildup, dampening, leaching latex, etc. These will quickly degrade the quality of your tiles, demanding frequent, unnecessary, and costly replacements.

Thus, make sure that the thinset or mortar for shower walls and floor you use, has an advanced and foolproof water-resistance feature.

3. Application Method

If you’re a beginner DIY enthusiast, a convenient and easy application method can save you from tons of unseen troubles. So, choose a pre-mixed thinset that spreads smoothly with an even concentration without much conscious effort on your part.

if you’re using tile spacers, ensure that the thinset allows you to set the spacers’ legs appropriately and is equipped with a wet suction feature.

We suggest, always opt for thinsets that allow enough time for tacking. Make sure that the thinset also allows ample time to reposition the tiles during installation. Specifically, if you’re a beginner, this feature can save you from making many costly mistakes, such as ending up with a crooked alignment.

Finally, ensure that the thinset offers a simple cleaning procedure, such as removing excess material using normal soap and water.

4. Protective Features

A premium thinset or mortar for shower walls will always have a high bonding strength and impact resistance. This will help tiles set in heavily used areas (e.g. shower floors and walls) to avoid getting cracked or fractured.

Also, buy thinsets that are equipped with anti-shrinking and anti-microbial features. This will increase the durability of your setup and keep it hygienic.

5. Health Safety

Purchase a thinset that offers a low VOC count, doesn’t emit any harmful chemicals during or after installation, and stays non-reactive to flame inducing catalysts.

Also, ensure that it doesn’t secrete any strong odor during application. This will keep your health away from being negatively affected by the product and provide a comfortable user experience.

6. Compatibility

Ensure that the thinset is compatible with your tiles' type and the nature of the setting.

For example, modified thinsets work well with most tiles and settings.

However, if you’re installing ceramic or porcelain tiles on a plywood base, using an uncoupling membrane sheet in-between, they won’t function very well. For this particular setting, an unmodified thinset will be a better choice.

Modified Versus Unmodified Thinset: Which One To Choose?

This is a complex issue that perplexes anyone who wants to buy the best thinset for shower walls or floor. However, we'll discuss the matter clearly here to ensure our readers know which one is the better choice and when.

Unmodified thinset is the earliest version of shower tile mortar. It’s manufactured by combining Portland cement, refined sand, and chemical agents that can absorb water to start a reaction known as “hydration”. However, they have lower adhesive strength. It also requires more time and experience to apply.

Modified thinset, on the other hand, is made from a combination of Portland cement, refined sand, and a variety of advanced additives, such as latex polymer. They have Increased strength, bonding power, lessens shrinkage, and provide impact resistance. So, using modified thinset as a shower tile mortar increases durability of the tiles. It also reduces tile cracking issues.

So, majority of the time, modified thinset is the right choice for you.

However, if you’re installing a membrane sheet in between the tile and concrete, modified thinset will take a long time (from 10 to 50 days) to dry. In cases like this, it’s better to use unmodified thinset to achieve a faster drying and cure time.

Sometimes you may have to apply both types in a single setting. For example, you can use an unmodified thinset between the tiles and the upper layer of the membrane and a modified thinset to bond the opposite layer of the membrane with a concrete base.

Frequently Asked Questions

1. Why Is The ANSI Rating Important For Purchasing Thinsets?

Answer: The American National Standard Institute (ANSI) rating can tell you about the type of thinset you intend to buy.

For example, if a rating starts with A118.1 that means it’s an unmodified thinset.

Modified thinsets usually have multiple ANSI ratings. For example, A118.1 followed by A118.11.

2. Does The Shape And Size Of Trowel Matter For Applying Thinsets?

Answer: Yes.

You must match the size of the trowel with the depth of the applied thinset.

Usually, when the layer-thickness of the thinset increases so does the trowel size. The thickness of the thinset depends on the tile’s surface. If it’s too jagged or uneven, the required amount of thinset will increase. So, you’ll need a larger trowel.

Also, your tiles' dimensions must be compatible with the trowel's size.

In terms of the trowel's notch shape, it’s three things:

a. Your Preference: Some have always worked with square notched trowels and, therefore, feel more comfortable with this particular shape. The same logic can be applied to those who prefer trowels with U-shaped notches.

b. Surface Coverage: Some tile surfaces achieve an even spread and better area coverage if a square notched trowel is applied while other surfaces do so with U-shaped notches.

c. Layout of The Setting: if the layout of the setting has tricky corners, a U-shaped notch will perform better.

3. What Is A Membrane Sheet?

Answer: It is a thermoplastic sheet.

There are various types, such as uncoupling, crack-isolation, and waterproof membranes. It’s placed between shower tiles and the base to improve impact and crack resistance, as well as for blocking latex leaching.

4. Why Is It Necessary To Use Thinsets For Installing Tiles On The Shower Area?

Answer: Using thinset to install shower tiles makes the tiles phenomenally water-resistant. It increases the adhesive strength between the tiles and the concrete or cement base. Thus, the structural integrity of the tile setting is not weakened despite heavy use and constant contact with water.

It’s needed to improve the health of tiles and base, saving you the cost, time, and stress of frequent repair and replacement.

5. As A Beginner, What Kind Of Thinset Should I Use?

Answer: If you’re just starting out, avoid unmixed thinsets like LFT and unmodified thinsets. We recommend using a premixed, modified thinset for beginners.

Don’t attempt complicated application procedures like combined thinset application, which uses both unmodified and modified thinset on different surfaces of a membrane sheet.

However, consider the tiles’ material and nature of the setting before making a final decision.

6. Can I Use Thinset On Large Surfaces, Such As A Pool?

Answer: Yes.

We recommend using a modified or LFT thinset for this purpose. LFTs work better for installing large tiles while modified thinsets provide the most effective water and impact resistance.

Final Word

Tiles, be it porcelain, ceramic, or stone, is usually our go-to choice for decorating shower walls. But if you fail to set them properly, various problems can occur. For example, loosening tiles, dampening, cracks, etc.

Using the best thinset for shower walls is the perfect solution to battle these issues. So, in this guide, we've taken a strategic approach for providing you all the necessary info in the shortest amount of reading time regarding this matter.

Whether you want a quick know-how or an in-depth knowledge about the most effective thinsets the market has to offer, hopefully this guide is all you’ll need.
