Comprehensive Guide on How to Install Stone Facades with Epoxy Adhesive

How to use epoxy adhesive to install stone facade

One of the methods of garnishing structures is to use stone as a facade. Today, this method has gained a lot of popularity and stone has become one of the most widely used building materials. But what worries users about installing a stone facade is that the stone falls due to numerous accidents and leaves casualties. According to the article on “The Application of Epoxy in Various Industries”, one application of epoxy adhesive is to install stones on the facades of buildings. For this reason, we want to acquaint you with how to use this product in this article, and explain the benefits of using it.

Methods of execution and installation of stone facades

Architects use two methods to execute the stone facade. One of these methods is the wet method or the use of grout. Another method is the dry installation of the facade.


Wet stone facade installation

In this traditional method, facade stones are laid in place and filled the back with grout. Once the mortar or grout has dried, the stone will stick to the surface. Installing a stone facade in this way takes a lot of time and requires more labor. In this method, the probability of the stone separating from the surface is high. Also, if the stone detaches from the surface, it is not possible to change or rebuild it. As a result, the cost of maintaining and repairing the stone facade performed in this way is higher.

Dry stone facade installation

In this method, several ways are used to execute the facade. This method is much safer than the previous method and has a longer lifespan. The cost of its installation is also very reasonable and is done at a higher speed. The use of bolts or the use of epoxy adhesive in this method increases the resistance of the facade against factors such as building subsidence, shrinkage, expansion, earthquakes, and so on. The disadvantage that can be obtained with the bolt method is that it is not possible to perform a broken or classic facade with it. There is also the possibility of cracks in the rocks when drilling them.

Execution of stone facade by wet method

Currently, the use of wet stone facade is the most common method of building facade. In this method, mortar is prepared using cement and sand. Of course, in order for the durability and viscosity of the prepared mortar to be suitable for this method, washed sand must be used. After preparing the grout, the stones are arranged and the grout is poured behind them. In order to make the result satisfactory, bran should not be used. Also, the prepared grout should have more cement. In this method, stone scoops are also used to ensure and strengthen the facade stone.

Execution of stone facade by dry method

There are three general methods for installing dry facade stone

Epoxy adhesive

Plant Scoop


To execute a stone facade in the first two methods, namely bolts and plant scoops, thick stones must be used so that the result is satisfactory. Also in these two methods, the stone will be placed from the wall with a small distance of about 30 to 45 mm. This causes airflow in this space and prevents cracking of rocks in different conditions. However, these two methods cannot definitely prevent the rock from falling against various factors such as temperature conditions, earthquakes, strong winds and so on.

In the third method, epoxy adhesive, thin stones can also be used. Also, epoxy adhesive causes long-term connection of stones to the facade and there is no need to worry about stone separation due to various factors.

Why is epoxy adhesive the best way to apply a stone facade?

Using epoxy adhesive to install facade stone is a new and modern method. Compared to methods such as the use of bolts or plant scoops, epoxy stone adhesive does not cause any damage to the stones and does not lessen the beauty of the facade. Using this method to install masonry has advantages that make users more willing to use this method. These benefits include the following:·        

  • Easy installation:
    As mentioned, it is easy to use epoxy adhesive to connect facade stones. The ease of doing so eliminates the need for special expertise.
  • High speed:
    The speed of working with this product when installing stone is so high that 30 to 40 square meters of stone can be installed per day. Of course, this is the case if you use only one installer.
  • Long service life:
    By using epoxy adhesive to bond surfaces together, you get a bond that maintains for many years. and in some cases, this connection may be permanent for life.
  • High strength:
    The use of epoxy adhesive in the installation of facade stone makes the connection of stones to the facade resistant to harmful factors. For example, the stones are never damaged by vibration or subsidence of the building and their connection to the facade is maintained.
  • Resistance to climate change:
    If you have installed the stone using epoxy adhesive, you should not worry about the impact of climate change, rain, and frost. Because the chemical formula of this adhesive is such that it is resistant to all these factors.
  • Fair cost:
    In other methods, the use of thick stones, aluminum substructure and anchor bolt implantation are expensive. But when using epoxy adhesive, all you have to do is prepare the adhesive and mix it using the method indicated on the packaging.

These advantages make epoxy adhesive the best way to install facade stone. Of course, this article briefly explained the benefits of using these products. For more information on the features of these products, check “What Is an Epoxy Resin? All You Need to Know About Epoxy Resin Adhesives”.

How to apply stone facade with epoxy adhesive

According to what we said in the “Comprehensive Guide to Using Epoxy Adhesive”, to install large stones that are used in the facade of buildings, you must use the spot installation method. In this method, it is necessary to put spots of glue in the back corners of the stone as well as it’s center. Then place the stone on the desired surface. With this method, the stone will stick to the surface effectively. It is recommended to use Megatite C and Megatite S epoxy adhesive for installing large slabs, granite, and marble stones that are used for stone facade. These adhesives are two-component epoxy adhesives and include epoxy resin and hardener.

Megatite C

A transparent two-part epoxy adhesive with consistency and void-filling properties is designed to bond various stone, concrete, metal, wood and fiberglass-based surfaces to each other, as well as the installation of facade stone. This adhesive is for applications where the transparency of the adhesive is considered.

Megatite S

A two-part epoxy adhesive with consistency and void-filling properties that is designed to connect different surfaces to each other with point installation method of stone, marble, granite, and large ceramic tiles in the construction industry. It is also used to repair stone and metal surfaces.

The characteristics of these adhesives include their good consistency. You can easily use them to install marble, granite, large ceramic tiles, etc. You can also seal marble, granite, etc. with these products.

The characteristics of these two adhesives are the same and they only have one difference related to their color. Megatite C has a light color and is the best option in cases where the beauty of the facade is considered. But Megatite S has a dark color. Therefore, after using this product to install facade stone, its excess must be cleaned. For more information about these products, you can refer to the article on Megatite C adhesive, which is published on this website.

Preparation of epoxy adhesive for stone facade installation

Due to the fact that epoxy adhesives are prepared in two parts, they are very easy to use. However, there are some things to keep in mind when applying epoxy adhesive to your stone facade. First, you have to prepare one of the two products introduced in the previous section according to the needs and working conditions. After preparing the epoxy stone adhesive, you must mix it according to what is written in the instructions for use. make sure to take as much glue from the container as needed. Finally, do not transfer any of the excess glue mixture to the main container. store resin and hardener at room temperature for 24 hours before mixing. This plays an important role in the performance of the adhesive in attaching the stone to the desired surface.

Preparing surfaces for stone facade installation

One of the steps of adhering to stone using epoxy stone adhesive is preparing the surface. To prepare surfaces, you must clean the desired surface from grease and dust. Also, the surface should be smoothed using abrasive rollers, and dust from abrasion should be cleaned using a fiber brush. Then clean the surface with a damp sponge and a dry cloth. Then the back of the stone should be sanded and cleaned. This helps the surfaces to stick together effectively succeed in the installation of the masonry.

Epoxy adhesive composition

In order to use epoxy adhesive, it must be mixed properly. This has a direct impact on the proper performance of the adhesive and its quality and durability. To mix Megatite S epoxy adhesive, you need to mix the resin and hardener in a 1: 1 ratio. 

But in the case of Megatite C, the resin and hardener are combined in a 3: 1 ratio. Observance of these ratios is very important due to the effect of the amount of these materials on the physical properties of the adhesive and its effect on the installation of facade stones.

It is better to read the user manuals and datasheets of epoxy adhesives for more details and familiarity with the mix ratios of adhesives.

Applying adhesive on the back of the stone

Once the adhesive formulation is ready, you can spot it on the back of the stone. To do this, simply use a spatula to apply epoxy stone adhesive to the corners and middle of the stone. The distance between the spots should be appropriate and equal.

Necessary measures after installing the stone

If the adhesive has spilled on the stone or leaked from the sides when using the glue to install the facade stone, you should clean them. To do this, you can use a thinner before the glue is fully cured. You can also remove excess by scraping them.
