Walk into almost any residential construction site in Pakistan and you will likely see the same thing: a worker mixing cement and sand in a pile on the floor, spreading it as a bed, then placing tiles directly into it. This has been the standard method for decades. It is familiar, affordable at the point of purchase, and most laborers know how to do it.
The problem is that it does not work as well as most people think it does.
Pakistan’s construction industry has changed significantly over the past ten years. Porcelain tiles, large format tiles, and natural stone have replaced basic ceramic in most projects. These new tile materials have very different installation requirements, and plain cement simply does not meet them.
This article breaks down the real difference between cement and tile bond adhesive, compares them on every factor that matters for tile installation in Pakistan, and gives you a clear answer on which one produces better results and why.

Why This Decision Matters More Than Most People Realise
A tile floor looks the same whether it was fixed with cement or with tile bond adhesive, at least for the first year or two. The difference becomes clear later.
Tiles fixed with cement start hollowing out. You can hear it when you walk across the floor: a dull, empty sound under your footstep instead of a solid thud. Some tiles begin rocking slightly when pressed at the edges. Others crack suddenly under a chair or table leg, at a point where the cement bed underneath had lost contact with the tile above.
When you lift those tiles, the story is obvious. The back of the tile is clean. The cement did not hold it. The failure was not a bad tile or a bad floor. The failure was the method used to bond them.
Choosing between cement and tile bond adhesive is a decision that determines how long your tile floor actually lasts. Getting it right the first time costs less than getting it wrong and relaying the floor two years later.
What Is Cement-Based Tile Fixing?
How Cement Works as a Tile Fixing Material
Traditional tile fixing in Pakistan uses a mix of sand and cement combined with water to form a thick mortar bed. This bed is spread on the floor, leveled, and tiles are pressed into it while it is still wet. In many cases, a thin paste of neat cement mixed only with water is applied directly to the slab surface just before placing the mortar, or spread on the back of each tile to improve contact.
Once the cement cures, the tile is held in place by a mechanical grip. The curing cement forms a hard material that locks around the rough texture of the tile back and the floor surface below. There are no chemical bonds involved. It is purely physical contact.
Why Cement Has Been Used So Long in Pakistan
Cement and sand are available everywhere in Pakistan. Every contractor knows the mixing ratio. Every laborer has applied it hundreds of times. The materials are cheap per bag, and no specialised equipment or training is required.
For the type of tiles that were common in Pakistan twenty years ago, basic ceramic wall tiles and simple unglazed floor tiles, this method worked reasonably well. Those tiles had high water absorption, porous backs, and were small enough that full contact with the mortar bed was achievable.
The Real Weaknesses of Cement for Tiles
Plain cement mortar has four fundamental weaknesses that make it unsuitable for most modern tile installations:
It is rigid once set. Cement mortar has no flexibility. Once it hardens, it cannot absorb any movement. Concrete floor slabs expand and contract with temperature changes. In Pakistan, where a rooftop or upper floor slab experiences temperatures from 10 degrees in winter to 50 degrees in direct summer sun, that thermal movement is significant. A rigid mortar bed cracks under that movement, breaking the bond at multiple points across the floor.
It has low bond strength. Sand-cement mortar achieves pull-off adhesion values of 0.3 to 0.6 N/mm² in standard conditions. These figures come from independent testing of typical site-mixed cement mortar beds. For comparison, quality tile bond adhesive achieves 1.0 N/mm² or above. That means tiles fixed with cement can be pulled loose at roughly half the force required to pull a properly adhesive-bonded tile.
It cannot bond to low-porosity tiles. Plain cement bonds partly through moisture transfer. The cement paste partially penetrates the pores in the back of the tile and forms a physical lock as it cures. For this to work, the tile must absorb some moisture. Porcelain tiles, which are now the most popular floor tile in Pakistani homes and commercial spaces, have water absorption below 0.5 percent. There is almost nothing for the cement to penetrate. The bond is surface-level at best and unreliable at worst.
It is too thick and too heavy. A traditional mortar bed is 30 to 50 mm thick. This adds significant dead load to the floor structure and raises the finished floor level considerably. Tile bond adhesive beds are 3 to 6 mm. For upper floor rooms and buildings where floor load matters, the difference is not trivial.
What Is Tile Bond Adhesive?
How Tile Bond Works Differently
Tile bond adhesive is a factory-produced powder made from Portland cement, graded aggregates, and synthetic polymer additives. You mix it with clean water to form a smooth paste, apply it with a notched trowel, and press tiles into it within the open time window.
When it cures, tile bond forms both a mechanical grip and a chemical bond with both the tile surface and the substrate. The polymer chains in the adhesive create molecular-level connections that do not depend on moisture absorption into the tile. This is how tile bond holds porcelain and glass tiles reliably, materials that plain cement cannot hold properly.
What Polymer Modification Actually Does
The polymers in tile bond adhesive serve three separate functions.
First, they improve adhesion to low-porosity surfaces. The polymer chains form connections at a molecular level with any clean, stable substrate regardless of how porous or non-porous it is.
Second, they add flexibility to the cured adhesive bed. Polymer-modified cement is not elastic like rubber, but it has enough give to absorb the small movements of thermal expansion and contraction that crack rigid cement mortar. This is what prevents hollow tiles from forming over time.
Third, they improve workability. Tile bond adhesive mixes to a smooth, consistent paste that spreads evenly, holds its position on walls without slumping, and compresses uniformly when tiles are pressed into it. Site-mixed cement mortar has inconsistent texture because aggregate grading and mixing conditions vary every time.
Head-to-Head Comparison: Cement vs Tile Bond
Bond Strength
Plain sand-cement mortar achieves pull-off adhesion of 0.3 to 0.6 N/mm² under typical site conditions. A quality polymer modified tile bond adhesive such as SB Grip Bond by StoneBird Chemicals achieves 1.12 N/mm², verified by independent laboratory testing to ASTM D7234.
In practical terms, a tile bonded with quality adhesive requires approximately twice the force to detach from the floor compared to a tile fixed with plain cement. This directly translates to tiles that stay firm under heavy furniture, frequent foot traffic, and the stress of thermal cycling.
Flexibility
Plain cement mortar has zero flexibility after setting. Tile bond adhesive, due to its polymer content, retains a small degree of controlled flexibility that allows it to absorb minor substrate movement without cracking. This difference alone accounts for a significant portion of why tiles bonded with adhesive have far fewer hollow spots after two or three years compared to tiles fixed with mortar.
Coverage and Bed Thickness
A 20 kg bag of tile bond adhesive covers 4 to 5 square meters at a bed thickness of 3 to 6 mm. A similar weight of sand-cement requires a bed of 30 to 50 mm to achieve a workable layer, covering far less area per kilogram and adding considerably more weight and height to the finished floor.
Working Time
Site-mixed cement mortar begins to set within 30 to 45 minutes depending on temperature, water ratio, and cement type. There is no controlled open time. Tile bond adhesive such as SB Grip Bond has a defined open time of over 30 minutes after application and a pot life of 3 to 4 hours in the bucket. This predictable working window allows installers to work at a careful pace without rushing, which directly reduces the installation errors that cause tile failures.
Performance on Different Tile Types
Cement mortar works adequately on basic ceramic tiles with high water absorption and small dimensions. It fails progressively as tile porosity decreases and tile size increases. On porcelain, its bond is unreliable. On large format tiles above 60×60 cm, achieving full back contact through a mortar bed is difficult even with excellent technique.
Tile bond adhesive works correctly on ceramic, porcelain, marble, natural stone, mosaic, and large format tiles of all dimensions. Coverage and technique requirements change with tile size, but the adhesive chemistry works across all these materials.
Performance in Wet Areas
In bathrooms, kitchens, and other areas with regular moisture exposure, plain cement mortar absorbs water over time. This gradual moisture uptake softens the bond at the tile-mortar interface and causes progressive loss of adhesion. The process is invisible from the surface until tiles begin to hollow or lift.
Polymer modified tile bond is water-resistant after curing. Its bond strength does not degrade progressively from moisture contact the way a plain cement bond does. For wet areas in particular, this difference in long-term performance is significant.
Why Plain Cement Fails on Porcelain Tiles
This deserves its own section because porcelain tiles are now the dominant choice in Pakistani residential and commercial projects, and the failure of cement on porcelain is the single most common cause of floor tile problems nationally.
Porcelain is manufactured at temperatures above 1,200 degrees Celsius. This firing process removes nearly all internal porosity from the tile body. The resulting tile absorbs less than 0.5 percent water by weight. For a material that needs moisture to penetrate its surface to form a mechanical bond with cement, this is a fundamental incompatibility.
When you spread cement mortar on a floor, place a porcelain tile on top, and press it in, the following happens: the cement surface contacts the porcelain back, but cannot penetrate it. The cement cures and forms a hard layer. The porcelain tile sits on top of that layer held only by gravity and friction. There is no real bond. Given enough time, thermal movement, or load concentration, the tile separates from the cement and becomes hollow.
You can verify this by lifting a hollow porcelain tile that was fixed with cement. The back of the tile will be completely clean. No cement will have adhered to it. All the cement stayed on the floor. The tile was never actually bonded.
Tile bond adhesive solves this because its polymer chemistry bonds to the porcelain surface through adhesion mechanisms that do not require moisture absorption. The adhesive grips the tile surface at a molecular level, creating a genuine bond rather than just contact. For a deeper look at how this works across different tile types, see best tile adhesive for marble, porcelain and ceramic tiles in Pakistan.
Why Pakistan’s Climate Makes Tile Bond the Smarter Choice
Pakistan’s temperature range is one of the most demanding for tile installations anywhere in the world. In cities like Lahore and Multan, upper floor concrete slabs reach surface temperatures above 60 degrees Celsius in direct summer sun. By winter evenings the same slab can be below 10 degrees. That is a swing of more than 50 degrees across a single year.
Concrete expands by approximately 0.01 mm per meter per degree Celsius. On a 10-meter roof slab, a 50-degree temperature swing produces about 5 mm of linear expansion and contraction across the full slab. Plain cement mortar cannot accommodate this. It cracks, the bond breaks, and tiles hollow out.
Polymer modified tile bond absorbs this movement through controlled flexibility. The tiles stay bonded across the full range of seasonal temperatures rather than loosening every summer and rehardening every winter with progressively weaker contact at each cycle.
For wall tiles on exterior or semi-exposed surfaces, the same logic applies. Paint-exposed plaster walls in Pakistani homes change temperature rapidly. Tile bond adhesive handles this. Plain cement or neat cement slurry does not.
The Real Cost Comparison Over Time
The argument for using cement over tile bond almost always comes down to cost. Cement and sand cost less per bag than tile bond adhesive. On the surface this is correct.
The calculation changes when you look at what happens over three to five years.
A 200 square meter floor fixed with plain cement on porcelain tiles in Pakistan will typically develop significant hollow areas within two to three monsoon seasons. Relaying hollow tiles requires lifting the affected tiles, which usually breaks a portion of them. New tiles must be purchased to replace the broken ones. The old cement bed must be chipped away and disposed of. New mortar or adhesive is required. Labor is paid again.
The total cost of this repair cycle, materials, tile replacement, and labor, typically exceeds the original saving from choosing cement over adhesive several times over. And the cycle often repeats.
A floor laid correctly with quality tile bond adhesive on a properly prepared substrate lasts the full lifespan of the tile without needing relaying. For common ceramic and porcelain tiles in residential use, that lifespan is ten to twenty years under normal conditions.
The upfront saving of using cement is real. The downstream cost of doing the job twice, or three times, makes the cement method more expensive in the long run for the majority of Pakistani tile installations.

How to Apply Tile Bond Adhesive Correctly
Good adhesive applied poorly still produces poor results. These steps ensure correct application.
Prepare the surface. The floor must be clean, dry, and structurally sound. Remove all dust, paint splatter, curing compounds, and debris. Sweep and if needed scrub the surface. Any surface contamination between the adhesive and the floor breaks the bond.
Mix accurately. Add 4.5 to 5.5 liters of clean water per 20 kg bag into a bucket first. Add the adhesive powder gradually while mixing with a low-speed drill mixer. Mix until completely smooth with no lumps. Rest for 5 minutes, then mix briefly again. Do not add extra water to a mix that has started to stiffen.
Spread in manageable sections. Apply with a notched trowel. Match notch size to tile dimensions: 6 mm notch for tiles up to 20×20 cm, 8 to 10 mm for tiles up to 60×60 cm, and 10 to 12 mm for large format tiles. Cover only the area you can tile within 20 to 25 minutes.
Back-butter large tiles. For any tile above 60 cm in any dimension, apply a thin flat layer of adhesive to the tile back as well. This guarantees full contact when the two adhesive surfaces are pressed together.
Press and set tiles firmly. Press each tile with a slight twisting motion to collapse the adhesive ridges. Use a rubber mallet to tap across the full tile surface for even contact. Adjust within 10 minutes of placement. After that, do not move the tile.
Wait before grouting. Allow a full 24 hours after tile placement before applying grout. Do not allow foot traffic during this period.
Common Questions About Cement vs Tile Bond in Pakistan
Can I use tile bond for outdoor tiles?
Yes. SB Grip Bond is suitable for exterior floor and wall tile installations. For outdoor surfaces, ensure the substrate is clean and stable and that tile joints are grouted with a product rated for outdoor exposure and temperature cycling.
Does tile bond work in bathrooms?
Yes, and it is the recommended method. Tile bond adhesive is more moisture-resistant than plain cement after curing. For bathrooms, apply a liquid waterproofing layer first, allow it to cure, then tile with adhesive on top. Never rely on tile adhesive alone as a waterproofing barrier.
How do I fix just one or two hollow tiles with tile bond?
Lift the hollow tile carefully using a grout saw to cut the surrounding joints first. Chip away the old cement or adhesive from both the floor and the tile back. Clean both surfaces thoroughly. Apply fresh tile bond to the floor and back-butter the tile. Reset and allow 24 hours to set before grouting.
Is tile bond suitable for heavy marble tiles?
Yes. SB Grip Bond handles marble and natural stone on both floors and walls. For large or heavy marble pieces, always back-butter the tile and use a notch trowel appropriate for the tile size. Full back contact is essential for heavy stone tiles to prevent cracking under point loads. For detailed guidance see tile adhesive vs mortar for floor tiles.
Where can I buy tile bond adhesive in Pakistan?
SB Grip Bond by StoneBird Chemicals is available through their distributor network across Pakistan including Lahore, Karachi, Islamabad, Faisalabad, and Multan. Contact StoneBird Chemicals directly for pricing and availability in your area.
Conclusion
Plain cement has been used to fix tiles in Pakistan for decades. It is familiar, widely available, and cheap at the point of purchase. But familiarity and affordability are not the same as performance, and for the tile types now used in the majority of Pakistani homes and commercial projects, plain cement simply does not deliver reliable long-term results.
Polymer modified tile bond adhesive bonds ceramic, porcelain, marble, and large format tiles reliably because it forms actual chemical bonds with the tile surface, holds flexible under thermal movement, and is tested to international standards that plain cement mixing on a construction site can never match.
The total cost over the life of the installation, accounting for repairs, relaying, and replacement tiles, makes quality tile bond the more economical choice for most projects. The initial saving from using cement disappears the first time a hollow tile cracks or a section of floor needs to be relaid.
