Installing Eldorado Stone

Alright guys, this is the place to learn how to install Eldorado Stone® and there are 2 ways to do it.

  1. The Traditional Installation Method
  2. The Cement Board Installation Method

The Traditional Installation Method:

Today we are going to focus on the traditional installation method of stone veneers. Let’s get straight to it…

Before beginning, select your stone, color and style of stone and finally, the technique you’ll use for grout. There is such a vast selection of style and color in stone styles ranging from old world to contemporary, and the end result can be changed to suite your theme based on the finishing technique of the grout installation alone. It isn’t complicated, just follow these steps.

Differentiate between three grout techniques you will use: Pick One


Grout Option 1:

Grout Option 2:

Determining surface area in square footage of your project: Multiply the length by the width to determine the area needed. (eg. 3ft x 4ft = 12 square feet).

If you have ANY questions or don’t know how to do this because it has been years, or you just can’t remember the right way to do it, EMAIL me! I will help you. I PROMISE!

Or, if there are a bunch of bends and elbows, take the rough outline (rectangle or square) in length x width and go with that. You will find extra projects to cover with the same matching stone. For example, and outdoor BBQ station.

Important note to consider: If you can use specifically designed stone corners, made by Eldorado Stone for this purpose, you will elevate the appearance of the finished product multiple fold. It will look much more realistic so try to plan for this rather than the mere placement of flat stones on a wall or object.

The idea is to create what appears to be a solid 3-dimensional bricks or rocks with substantial depth that are bound deep into the surface with mortar. We are replicating the real thing here right? Think 3D-looks better.


Tools for the Stone Veneer Job in the Man Cave

Stone Veneer Installation

Stone Veneer Installation


OK folks, Onto Preparation of the Surface at Hand

In this section, we are going to discuss the installation of veneer stone over sheathing as it is one of the most popular forms of installation, and the supplies will be the easiest to find AND work with.

  1. This installation is done over sheet-rock, or drywall.
  2.  Apply a single layer of WRB (water resistant barrier), over the project surface. This WRB material will either be: a) House Wrap such as Tyvek, b) Number fifteen felt or c) grade D paper. A double layer is to be used for outdoor applications. In any case, ensure that the water resistant barrier is approved by local building codes. Keep reading on how to tack it up.
  3. Apply your WRB in a horizontal fashion starting from the bottom.  ENSURE that you OVERLAP at a minimum of 2 inches horizontal, and 6 inches vertical. Think of where moisture could run in between edges of the WRB and how this principle applies, then it will make more sense. OR think of it this way… If the paper is overlapping as flipping pages were to in a book then it is 2 inch overlap. If it is going to be a vertical overlap, then think of it this way: place your initial sheet on the wall, AT THE BOTTOM, then place the second piece on that original piece, but over lapping 6 inches. Think of shingles on a house. They overlap a certain degree to prevent wicking back under the previous material.  Attach the WRB to the studs with glavanized nails or staples.
  4. Ready for this?  2 and a half pound, galvanized, corrosion resistant, self-furred, metal lath. YUP. We need to apply this stuff that looks like tight chicken mesh ;-), except the holes are about 1 cm by o.75 cm.  You will notice something different though… The little diamond-shaped holes will need to be applied to the wall so that when placed against the wall, the little diamond shaped sections form a  cup at the bottom of each hole. This holds the mortar in place when it is applied in the future. For example:

Man Cave metal lath to install stone. Ensure the cups face up. Attach using galvanized staples or nails.

The nails will be installed six inches on the vertical and sixteen inches on-center horizontal. Ensure the studs are actually  penetrated here and that they are penetrated by at least one inch- so this means a 1.5 inch staple. Remember, there is quite a substantial amount of weight we are erecting here. Lath will be overlapped a minimum of one inch on vertical and horizontal seams. At corners, DO NOT end the lath, wrap the lath around to the next stud if this is a possibility.

6.  Prepare the mortar using a premixed Type-S mortar and follow the instructions on the bag.

7.  Apply a layer of mortar to the lath:

8. Once the Mortar has set and is “thumb-print hard” as seen in the picture below, the next step will be to scratch the surface of the project horizontally with a scarifier. See below.

The Next EASY Step: Applying your Eldorado Stone the following day

  1. Remove stone from a number of your boxes to ensure that you are  able to lay out a large variety of shapes and colors on the floor. We want to create variability in color on the project. In other words, don’t use stones from one box until it is empty and then move onto the next box and so on because if you do, there is a chance that you will have a grid of lighter shade sections against darker shade sections all throughout your project.  Remember that there are a thousand variables in the creation of the stone including the humidity in the drying time during the manufacturing process. It can’t be avoided, so to combat this effect in slight color difference and lot numbers, YOU will lay out a 5 foot by 5 foot section of stones from various boxes and mix and match the colors that way to create a natural uniform look of variability as seen in nature.   Important do this to look like a pro to your buddies and everyone else. Create yourself a quality project here. Do the same with the corner stones. Sort them out before you begin to apply them. We will be starting with the corners of the project first.
  2.  Next,  Spray the back of the stone veneer and the scratch coat with a spray/mist bottle.
  3. Throw on a half-inch layer of mortar (type s) onto the back of the piece of the stone veneer you are about to apply, then spread around evenly with a trowel. Begin with the corners first as seen in the second picture below.

4.  With light to medium pressure, rock and wiggle the stone piece into place until you see mortar start to ooze out around all of the edges of the veneer piece. Once the stone is set, don’t move it to avoid breaking the new bond you have created.

5. Alternate pieces down the wall corner to create variability. Work from the top of the wall down. This prevents falling dollops of mortar from splashing onto stones below and making a mess.

6. Your finished corners of your project may look like this:

7.  Continue placing stones throughout the rest of the project until the entire wall is finished. Remember to start at the top and work down the wall to the bottom.

Next Step: Applying Grout to the Stone

Fill 2/3 of the grout bag with the mixture. Twist the end to squeeze grout into the crevices between the rock. Ensure the grout fills the entire depth of the  crack to the wall.

when finished, wait until the grout is thumb-print hard

Using the striking stick, scratch away the excess grout to desired depth.

Finally, use a stiff-bristled brush to smooth out the lines and create the proper textured finish to the grout.
