Versabond vs Mapei: Key Differences

Bonding Strength

The bonding strength of your thin-set will determine how well it adheres to the surface and the tiles.

You’ll always want to use a thin-set with higher bonding strength.

For concrete floors and walls, Mapei provides excellent bonding strength. It also features a quick-drying mechanism, so it dries faster than Versabond.

Versabond, on the other hand, can give excellent bonding strength to plywood and concrete. In terms of bonding strength, it outperforms Mapei.  This is because it contains modified agents.

Modifier Amount

A thin-set may either be modified or unmodified. The modified thin-set has polymers formulated into the dry mix. These polymers enhance the performance and strength of the thin-set.

Versabond is a modified thin-set that contains a lot of acrylic latex modifiers. The modifiers allow it to be incredibly flexible and powerful.

Mapei, on the other hand, is an unmodified thin-set. As a result, there is no latex modifier in it. In terms of modifier amount, Versabond comes out on top.

Sand Grind

One of the essential components of thin-set mortar is the sand grind. Sand grind size is important because the larger the sand grind, the more weight a thin-set can absorb. If you use a thin-set with huge sand grinds, it will not sag from the wall due to the weight of the huge tiles.

The sand grinds in Mapei thinset are larger than in Versabond. As a result, the weight of huge tiles will not cause it to sag.

The term “large tile” refers to a tile that is longer than 15 inches on one side.

Work Time

Not all thin-sets take the same duration to finish. Some require more time to set, while others require less. You can complete your project quickly if you use one that takes less time.

Versabond takes a little longer to dry than Mapei thin-set. This has both advantages and disadvantages. The con is that it will take longer to become set on the surface due to the prolonged working time.

However, because you will have more time, it will be easier to correct any mismatched tiles.


The thin-set required to cover a given area is referred to as coverage. You’ll need less thin-set mortar if your thin-set has broad coverage. It will also save you money.

To cover an area of 85 square feet, you’ll need about 50 pounds of Versabond thin-set. On the other hand, the same area may be covered with only 28 lbs of Mapei thin-set. As a result, Mapei will provide you with more coverage.

Moisture Factor

Thin-set mortars are well-known for their ability to work in wet environments. They can be used on the floors and walls of your bathroom.

As a result, moisture is an important consideration. Thinset that has a higher moisture content is preferable.

Mapei contains a lot of moisture-resistant substances. You don’t have to be concerned about using a Mapei thin-set for shower walls.

Versabond, on the other hand, is not known for its moisture resistance. It is moisture-resistant as well, although not as well as Mapei.


When it comes to thin-set mortar, the cost is a significant consideration. You’d prefer one that offers higher performance at a lower price.

A 5-pound bag of Mapei thin-set will set you back roughly $28. A Versabond 50-pound pack, on the other hand, will set you back only $15. As a result, Mapei is the most expensive.
