Common Mistakes to Avoid When Applying Tile Adhesive

Installing tiles is more than just laying them in straight lines it’s a precise process that depends on the right materials, techniques, and timing. Tile adhesive plays a crucial role in ensuring tiles stay fixed, aligned, and durable over time. Yet, despite its importance, many tile failures stem from simple adhesive-related errors.

Why Tile Adhesive Matters?

Tile adhesive is the bonding agent that holds tiles to their substrate. Unlike traditional sand-cement mixes, modern tile adhesives offer faster setting, better adhesion, and are easier to work with—especially with today’s low-porosity tiles. The right adhesive ensures:

• Strong and lasting bonds
• Moisture and temperature resistance
• Even tile surfaces without gaps or hollow spots
• Greater durability in high-traffic or wet areas

Whether you're a professional contractor or a DIY enthusiast, avoiding few mistakes can significantly improve your tile installation’s quality and longevity. Starting from the correct adhesive to equipment to application, here in this guide we will inform you of the common errors to be avoided and some practical tips which will ensure that you achieve a long-lasting professional finish.

Tile installation is a careful process that requires clarity, accurate knowledge, planning and execution. Even small errors during fixing can result in poor work, expensive repairs, and reduced tile lifespan. Let's see why tile adhesives are important during tile installation before we explore the common mistakes during tile installation.

Tile adhesive is used to stick the tiles to surface below it- this surface is called the substrate. It is a mixture formulated very carefully. Earlier sand and cement were used to stick the tiles, but tile adhesive used in modern times has many benefits. They provide stronger bonding strength, quicker setting time, and are simpler to use.

Magicrete provides premium tile adhesives that are specifically formulated for various surfaces, types of tiles, and uses. From tiny ceramic tiles in kitchens to huge slabs in public areas, the proper tile adhesive guarantees:

• Strong and durable bonds
• Smooth and even tile surfaces
• Moisture and temperature resistance
• Less cracks and gaps over time

Since now we know the significance of the tile adhesive, let's explore some typical errors people make during its application—and how you can avoid making those errors.

This is a very frequent and most common mistake. The most suitable tile fixing adhesive is not effective if the surface is not prepared. Surfaces must be leveled, clean, dust-free and free from oils. For a successful bond, moisten dry surfaces before using adhesive. Dampen dry surfaces prior to application for a firm bond.

What fails?

Most people do not pay attention to surface leveling or cleaning before applying adhesive. This leads to poor adhesion and detaching over time. So, it is very important for the surface to be clean, dry and smooth for tile adhesive to stick properly. Improper site preparation can result in poor adhesive application and premature detachment of tiles.

Why it’s a mistake?

Without proper surface preparation, the tiles will not stick correctly, and this can cause uneven surfaces, cracking, or loosening after some time. Skipping this process leads to expensive repairs and an unpleasant finish.

How to avoid this:

Before laying the tiles make sure the surface is clean, dry and levelled. Remove any existing build-up that may get in the way of bonding like adhesive, paint, or dirt. If the surface is uneven use a levelling compound to make the surface even and smooth. Proper preparation of site also includes checking the substrate (the surface on which the tile installed) is stable and crack free. For wet areas like bathrooms, make sure the surface is dry and moisture proof before application.

Quick Tip: Remember that a well-prepared surface is the most important part of perfect tile installation.

All tile adhesives are not equal. Applying the wrong one may result in inefficient bonding, particularly in zones that are wet or subject to temperature variation. Choose adhesive based on tile type, surface condition, and application area. More importantly, the adhesive you use should comply with IS 15477 (Indian Standards for Tile Adhesives) that ensures quality, bonding, durability and safety. It’s the Indian Standard for tile adhesives, and it defines which type of adhesive should be used for what kind of tile and surface (like ceramic, vitrified, natural stone, interior, exterior, wet areas, etc.).

If your adhesive doesn’t comply with IS 15477, you are risking poor quality, failed installations, and future repairs.

What fails?

Choose the type of adhesive which is compatible with the type of tile and surface you are laying on. For example, if you use a normal adhesive for heavy tiles or wet surfaces such as bathroom it will lead to tiles cracking, or tile detachment after some time. When choosing the right tile adhesive, one should consider the different types as defined in the Indian Standard (IS) code IS 154772019. The code classifies adhesives into three types (Type 1, Type 2, Type 3, Type 4 and Type 5) depending on their composition, strength, and purpose of use.

Why it’s a mistake?

Using the wrong adhesive on your tiles can lead to tiles cracking, moving, or falling off completely. Using the incorrect type can result in a poor finish. For example: Cement based adhesives are suitable for regular indoor tiles but can be unsuitable for big tiles or busy areas. While epoxy adhesives perform suitably in areas where there is moisture exposure, i.e., the kitchen and bathroom.

Understand your project requirements for tile type, installation area and conditions prior to selecting an adhesive. But here's something many people ignore, not following IS code guidelines.

How to avoid this:

The right type of adhesive should be selected based on the type of tiles (for e.g. ceramic, porcelain, natural stone) and area of application (for e.g. indoor, outdoor, bathroom locations). For heavy or large tiles, high bonding or stronger adhesives are used. Bathroom areas require waterproof adhesives for creating solid adhesion. Carefully refer to the instructions given by the maker for proper blending, usage, and time allowances for drying. Look for adhesives that meet IS standards like IS 15477 to ensure your product is tested and certified for performance.

Quick Tip: Magicrete has wide range of IS 15477-compliant adhesives for every type of tile and condition.

Proper mixing of the adhesive is also as important as choosing the right one.

What goes wrong?

Incorrect mixing of tile adhesive—e.g., adding excess water or excessive agitation can weaken its consistency and bond strength. When the mixture becomes too wet, it loses bond strength. If it’s too thick, it will not spread evenly. Some people even add water later to reuse dried adhesive—which ruins its performance.

Why it’s a mistake?

Wrong blending can lead to an adhesive that is too watery or too thick, and this will produce poor adhesion and possible displacement of tiles with time. It will loosen or cause tiles to pop off, particularly in heavily used areas or under heavy loads.

How to prevent this:

Always follow the manufacturer's instructions. Use clean water according to the required ratio. Blend only as much as you will use within the working time (typically 30–45 minutes). Never mix water into drying adhesive—this reduces its strength. Adequate mixing guarantees smooth application and good bond strength. Always follow the manufacturer's water to adhesive ratio. Use a slow speed mixer to gradually mix and form an even consistency mixture without air bubbles. Make sure the adhesive is lump free and uniform in consistency.

Quick Tip: Let the combined adhesive slake for a few minutes before a final stir so that it lets the polymers activate and optimize the adhesive's bonding.

How much tile adhesive you put down has direct implications on whether or not your tiles remain fixed.

What goes wrong?

Using excessive adhesive causes it to ooze out of the sides or make tiles lumpy. Too little adhesive results in gaps under the tiles, producing hollow noises and weak areas.

Why it’s a mistake?

Using excess of adhesive will push the tiles away or make the surface irregular, and very little use of adhesive will create hollow spaces and poor adhesion. This will cause cracking or loosening of tiles over time.

How to prevent this:

Use the correct notched trowel size for your tile size to have an even spread of the adhesive. Ensure that the adhesive spreads at least 80–100% over the back of the tile, particularly in wet conditions. Hold correct thickness according to tile size and surface type. Spread the adhesive using an even angle and pressure to hold even thickness.

Quick Tip: Even application of adhesive prevents future issues with tiles.

Good tools equal good work—and that's really true for installing tiles.

What goes wrong?

The use of the wrong random tools can cause uneven application of the adhesive, sub-standard tile levelling and out-of-line tiles.

Why it’s a mistake?

The inappropriate tools may undermine the quality of the installation, resulting in possible tile failure and aesthetic problems. For instance, installation with an old trowel may create uneven adhesive thickness.

How to prevent this:

Tools needed:

• Notched trowel – distributes adhesive in ridges for high grip
• Rubber mallet – taps tiles gently for improved bonding
• Tile spacers – maintains alignment and uniform spacing of tiles
• Leveling system – prevents one tile from sitting higher than the other (known as lippage)

Invest in good quality tools such as the right notched trowel, tile spacers, and a level to guarantee accurate installation. Check your tools regularly and keep them in good working condition.

Quick Tip: Clean your tools frequently during the installation process to keep them effective and avoid adhesive accumulation.

Timing plays a critical role when dealing with tile adhesive. Every type of tile adhesive whether cement-based, polymer-modified, or epoxy comes with a predefined “open time” as per IS 15477, the Indian Standard for tile adhesives.

This open time is the maximum time allowed between spreading the adhesive and placing the tile on it. Ignoring this timing leads to poor installation quality and shortens the life of your tile work.

What goes wrong?

Some individuals lay adhesive on an extensive surface area and subsequently wait too long before laying the tiles. At this point, the adhesive begins drying and sets off skin formation. This decreases the bonding strength. Over time, this leads to tiles becoming loose, developing hollow spots, or even detaching completely.

Why it’s a mistake?

Waiting too long following spreading adhesive makes it skin over, so it loses bonding capability. The adhesive becomes ineffective when it is in the early stage of dryness, hence a poor adhesive or failure during installation. Such failure can mean the tiles won't bond suitably and subsequently start to break loose.

This issue happens when you ignore the recommended open time of the adhesive, which is the amount of time in which you have to place the tiles after spreading the adhesive.

As per IS 15477 (Indian Standard for tile adhesives), each adhesive has a predefined open time that ensures proper bonding. Not following this timing is a key reason behind poor tile installation and weak adhesion.

How to avoid this:

Spread only as much adhesive as you can cover with tiles within the manufacturer's specified open time. Keep an eye on the surface of the adhesive; when it skins, scrape off and reapply the new adhesive prior to installing tiles. Follow manufacturer instructions and always check if your adhesive meets IS 15477 standards for open time and performance.

Quick Tip: Work in small sections for proper adhesion and strength.

Just as with cement, tile adhesive requires good time to dry and cure.

What goes wrong?

Failing to provide enough time for the adhesive to dry and cure can weaken the integrity and longevity of the tile installation.

Why it’s a mistake?

Walking on tiles or grouting before the adhesive hardens can cause loosening of tiles, misalignment, and weaken bonds. and deterioration of the work. This may make tiles shift, crack, or loosen over a period of time.

How to prevent this:

Strictly follow the recommended drying and curing times of the adhesive manufacturer prior to moving on to the next steps. Avoid walking or standing on tile area until the adhesive is completely cured. Do not grout when the adhesive is not yet fully set.

Quick Tip: Patience at this stage results in long-term effects.

Even with everything else being right, wonky tiles will ruin the whole appearance.

What happens?

Tiles will sink a little or become lopsided—particularly with larger tiles. Not regularly inspecting tile alignment will cause uneven spacing and a misaligned finish.

Why it’s a mistake?

Misaligned tiles can impact overall appearance and would need to be reinstalled, adding time and expense. It can also contribute to uneven lines of grout and an unprofessional look.

How to prevent this:

Use tile spacers and a level to maintain consistent spacing and alignment during the installation. Check for alignment using a spirit level or a laser level from time to time. Occasionally take a step back and look at the layout visually to detect and rectify misalignments early on.

Quick Tip: Double-check alignment at all times while you work row by row.

Modern tiles possess extremely low absorbency (less than 3% porosity) and thus the old sand-cement mix proves inefficient after a while. When tiles are fixed with the same old technique, there is a high chance of voids being created beneath them. The voids make the surface of the tile weak and cause future cracking or debonding. The sand-cement mix, too, without additives dries too fast, adding to the risk of tiles loosening before time.

Magicrete Tile Adhesives provide a scientifically formulated alternative. They blend graded sand, cement, polymers, and specially designed additives to form the ideal bond between tiles and substrate. This proprietary blend enhances workability and provides even application with a trowel, greatly minimizing the risk of cracking or hollow spots.
