Why Thinset is Better than Mastic for Shower Walls?
Mastic is another type of tile adhesive that is often used for wall applications. It is a sticky paste that comes pre-mixed in a tub and is easy to apply and adjust.
However, mastic has some disadvantages when compared to thinset, especially for shower walls. These include:
- Mastic is not very water-resistant. It can lose its adhesion and deteriorate over time when exposed to moisture and humidity. This can cause the tiles to fall off or crack.
- Mastic can also promote mold growth in wet areas, as it contains organic materials that can feed mold spores.
- Mastic is not suitable for large or heavy tiles, as it can sag or slide under their weight. It is also not recommended for tiles larger than 8 by 8 inches or for glass tiles.
- Mastic cannot withstand high temperatures, such as those from steam showers or radiant heating systems. It can soften or melt under heat and compromise the integrity of the tile installation.
Therefore, thinset is a better option than mastic for shower walls, as it can overcome these challenges and provide a durable and long-lasting result.

How to Apply Thinset for Shower Walls?
Applying thinset for shower walls requires some preparation, skill, and patience. Here are some steps to follow:
Prepare The Substrate
The substrate is the surface on which you will install the tiles. It should be clean, dry, flat, smooth, and stable.
If the substrate is porous or uneven, you may need to apply a primer or a leveling compound before applying thinset.
Mix The Thinset
Follow the manufacturer’s instructions on how to mix the thinset with water or other additives.
Make sure that the mixture is smooth and consistent by using a drill with a paddle attachment. Do not mix more than you can use within 30 minutes or before it starts to harden.
Apply The Thinset
Use a notched trowel to spread an even layer of thinset on a small section of the substrate.
The size of the notches depends on the size of the tiles; larger tiles require larger notches. Hold the trowel at a 45-degree angle and comb through the thinset in one direction.
Install The Tiles
Press each tile firmly into the thinset with a slight twisting motion to ensure good contact. Leave a small gap between each tile for grout later. Use spacers to maintain even spacing and alignment.
Clean The Excess Thinset
Use a damp sponge or cloth to wipe off any thinset that oozes out from the joints or the edges of the tiles.
Let The Thinset Cure
The thinset must cure for at least 24 hours before grouting or using the shower. Do not disturb or touch the tiles during this time.
How Thick Should Thinset Be for Shower Walls?
The thickness of thinset for shower wall tile should be between 3/16ths of an inch and 1/4th of an inch thick.
Is Thinset a Cement?
Yes, thinset is a type of cement that is used as an adhesive mortar for attaching tiles or stones to surfaces such as cement or concrete. It is actually a mix of water, fine sand, and cement.

SimpleSet Pre-Mixed Thin-Set Mortar is the best thinset for shower walls, as it provides a strong, water-resistant, and durable bond between the tile and the substrate.
