Primary Difference Between Wonderboard and Durock

differences between Wonderboard and Durock

Finding out the primary differences between the products will help us understand the products better.

With a better understanding, we will be able to figure out which product is suitable for us as we learn about the building materials, quality of the products, weight, pricing, and so on.

  • Building Materials

The building blocks of a product, as in the building materials are the defining factors of a product. They determine the overall quality of the products made of them.

Better materials bring out long-lasting products. They will not only fulfill their primary purpose but also provide service for a longer period.

Wonderboard uses Portland cement combined with EPS (expanded polystyrene) beads, aggregates, and fiberglass reinforcement.

They are less stiff than Hardibacker but enough to be used for curved surfaces. But it has its drawbacks.

Even a little bit of hole in its grout and the tile base becomes vulnerable to water and its purpose remains unfulfilled.

In the case of Durock boards, we get far better materials and even better performance compared to the Wonderboards products. It has glass mesh combined with cement as its building material.

This not only makes it a better choice but also a durable and well-performing product in comparison.

The glass mesh makes it harder for the moisture to break in and hurt the tile base. This combination makes the backer board smoother and lighter.

For this reason, it is easier to work with Durock rather than Wonderboard backer boards for your bathroom tiles.

  • Design & Product Quality

Both companies have various sized backer boards for your bathroom tiles. It is only your choice which company to choose. Because in this factor there is no particular design factor for backer boards.

As they are both providing similar services in consideration to design, none of them have the upper hand.

Now for quality, we can realize that the product quality is far better in the Durock branded backer boards. They provide better water protection, easier installation, and maintenance. 

Moreover, they are less expensive than the Wonderboards. It is clear which is the winner in this factor.

  • Weight

Another important factor for judging these products is their weight. The heavier the product the harder it becomes to work with. 

Let me explain. 

When you work with lighter products, it has an easier installation process.

Another positive side of lighter products is they are easy to fix or change. You will have an easier time than heavier products. This is a win-win scenario from my perspective.

The Wonderboards are heavier and stiffer than the Durock backer boards. The Wonderboards make even the easiest installation process harder.

With the Durock backer boards, you will find the installation process a piece of cake. But there are other things to consider, let us move on. 

  • Pricing

Now comes the elephant in the room. Price is the biggest factor when we consider buying something. It is not always good to assume that the higher the price, the better the product.

But it is undeniable that pricy products have their points of attraction which makes them costlier.

Between the products, the Durock backer boards are less expensive than the wonder boards.

One 3-ft X 5-ft X 1/4-ft of Durock branded backer board costs 10.98$. Alternatively, the same size of Wonderboard branded backer board costs 12.89$. 

Wonderboard Backer boards are pricier than the Durock backer boards.

  • Is Wonderboard Waterproof or Durock

An important aspect is to learn their waterproofing capabilities. As we are finding the best backer board for bathroom tiles, we will need one that is waterproof. 

A product that can provide better protection from moisture and mildew.

The Wonderboard is not affected by water yet it is not completely waterproof. It requires the use of a moisture barrier or waterproof membrane. The membrane protects the tile base from getting wet.

Durock boards are water-durable tile bases for showering areas and tubs. Even so, they too are not completely waterproof.

Wonderboard Lite Vs. Durock

Before we do the final judgment, we should consider a variation of the Wonderboard product. This variation is known as Wonderboard lite. 

In comparison, there is not much difference from the original. The lite version is 20% lighter. It is made with a mixture of mesh-reinforced fiberglass and stable Portland cement. 

Even though moisture resistant, not completely waterproof. Has better flexural strength meaning easily bendable. More or less, it is similar to the origin but lighter.

The Survivor of The Comparison

Before we conclude this article, we must choose the winner product. Companies of both products showed much consideration with their products. 

Both companies are making such fine backer boards but only one can go into your house.

As waterproofing is out the window, it makes it harder for us to find the better choice. Considering the overall quality of the products and pricing we can say that Durock is the better option.

Durock boards are cheaper, lighter, smoother. They are easy to install, easy to replace, and will cost you less than the Wonderboards products.

But if you are considering buying a cement-based backer board instead of glass-mess ones, then the Wonderboards are the one to go for.
