Epoxy River Simulation

How to Simulate a River Bed in Epoxy


A customer asks, “I recently saw what looks like a creek bed built out of epoxy with stones in it. How is this done in epoxy?”

Here are the steps to do it:

  1. Choose your stone. The stone that you choose can be uniform in size or a blend of stone sizes and shapes.  If bigger stone is going to be used, it is recommended that you use a blend of larger stone with smaller stone.  Variations in shape will also help to increase the amount of surface area holding the system together, making it stronger. Be sure the stone is clean and completely dry before attempting any of the steps below.
  2. Make a mock-up of the complete system below in a small box made out of plywood or similar material. This will verify everything from stone selection, to aesthetics, to stone durability. It is also gives you a chance to practice your procedure,and get additional phone tech support from us if required before you proceed with your project.
  3. Construct the recessed area that your river will “flow”. That could be a recessed area in a concrete floor, a wooded shadow box or some other “box” to hold your river. Be sure the box is watertight and that the surface is properly prepared before proceeding –www.epoxy.com/surfaceprep.aspx
  4. Prime the area created in step 3 with Epoxy.com Product #12 – www.epoxy.com/12.aspx at a rate of 250-300SF per gallon.  Allow to cure until hard to the touch, typically 6-8 hours
  5. After the Primer in Step 4 is hard to the touch and before 24 hours has passed, apply a coat of Epoxy.com Product #1 – http://www.epoxy.com/1.aspx – 100% solids General Purpose Epoxy Coating to the bottom of the box created in Step 3.  This will help to give you a consistent background color. Black helps give you the illusion of infinite depth.
    1. Optionally you can add a second coat of the #1 Pigmented Epoxy Coating to increase color intensity.
    2. On the other hand if the stone in Step 6 is so deep that you will not be able to see through it you can skip this step and proceed to step 6.
    3. Allow the epoxy in Step 5 to cure hard to the touch before proceeding, typically 10-12 hours.  Do not wait more than 24 hours before moving on to Step 6.
  6. Properly mix Epoxy.com Product #17 – www.epoxy.com/17.aspx – Epoxy Stone Adhesive Part A and Part B. Add your stone into the mixed stone adhesive.  The amount of stone that you will be able to add to it will vary depending on size and how clean the stone is.  100 lbs per 3 quart batch (2 QT “A” and 1 QT “B”) is a good starting point.  This ratio should be verified in a mockup before proceeding to this step. Mix in the stone until a uniform shine can be see on all the stone. Install this mix into your “box” at the desired thickness. Be sure to pack it in tightly and level to the desired surface.  Allow to harden overnight. Do not wait more than 24 hours before moving on to Step 7.
  7. Properly mix and pour Epoxy.com Product #214 – www.epoxy.com/214.aspx – Table Top and Casting Epoxy into the spaces between the rock in step 6. You typically will want to pour a minimum of 1/8 inch or not more than 1/2 inch at a time.  Take care to break any bubbles as you go early and often.  This is typically easy to do using a hair dryer and/or Isopropyl (rubbing alcohol mist). Allow each layer to harden and cool before adding another lift.  Never wait more than 24 hours in between coats and/or pours of epoxy.

When you complete this project it will look like a stone riverbed filled with \ water.  You can also experiment with other objects in your stone mix.  Contact Epoxy.com Technical Support with your questions: info@epoxy.com or 352-533-2167


Choosing Stone for Epoxy Stone

May 5, 2016

Epoxy_Stone_OverlaysBonding stone together with Product #17 – Epoxy Stone Adhesive is attractive and functional. It allows you to have the look of natural rock. This “natural rock” will let water pass through it just like its non-epoxied counterparts. It is however a good choice when you don’t want that stone to be moved, accidentally or on purpose.

This function is so nice that I am seeing projects where larger and larger stone is being utilized for the same reasons (above) as the small stone. There are a few shortcomings that should be avoided when bonding larger stones.

You want to make sure when selecting your stone that it is not too round. Round stone reduces the square inches of surfaces touching each other that are bonded together. That reduces the strength of the material, by reducing the square inches of bonding surface. If angular stone is used (as in the picture above) you increase the surface area touching each other and increase the strength.

If you want larger stones in the mix, I suggest you use a variety of smaller stone to fill in the large gaps between the bigger stone. If you combine a mixed gradation of stone that is also angular (not round) you can get an excellent compromise of strength and large stone beauty.

Selecting the Right Floor for a Mechanical Room

July 27, 2015

Mechanical Room Floors are very unique in their use and conditions. You have to consider the installation environment and the function of the floor. Our Mechanical Room Floor will protect the concrete, and contain any liquids that spill.

Systems used in mechanical rooms should be zero VOC. You do not want solvent evaporating from your material. Evaporated solvent could be picked up by your air handling unit sending it through your building. The best way to prevent this is with a VOC free 100% solids resin system. A resin system that is 100% solids has no solvent (or water) in it. It also means when you spread a gallon of material on your floor after it hardens you still have a gallon of material. With water-based and solvent based materials you lose half the material to evaporation.

Mechanical rooms should be chemical resistant. Typically they are top coated with Epoxy.com Product #2 Chemical Resistant Epoxy – www.epoxy.com/2.aspx. If it is a chemical feed room you can supply a list of chemicals and concentrations to the technical support department so you can make sure the #2 is chemical resistant enough.

The systems used for mechanical rooms are impact resistant. The limiting factor is the strength of the concrete substrate. Properly installed the epoxy will stay bonded to the concrete. The only way the epoxy can chip is if you chip the concrete from underneath the epoxy. You can install a thicker epoxy floor for an additional cost if you think you need still additional protection.

The systems recommend for mechanical rooms are highly abrasion resistant and will easily handle traffic up to heavy fork lift traffic. The system can be made even thicker if you have an unusual amount of abusive traffic.

When the mechanical room is over a finished space, it is suggested that a crack isolation membrane be integrated into the system. This can be done with Product #32 Epoxy Membrane System. The advantage of #32 Epoxy Membrane Resin as part of the system is 100% solids and has zero VOCs.

If the mechanical room is shut down and you can handle solvent and want something still more flexible you can use Epoxy.com Product #459 a two component, high solids, elastomeric urethane instead of or in addition to the Product #32 Epoxy Membrane above. Product #459 exhibits excellent elongation properties along with high tensile strength and tear resistance to make it an ideal crack resistant membrane for use under Product #2 and all of our other epoxy mechanical room floor coatings.

One of the primary reasons you need a mechanical room floor over finished space below is to waterproof it. The above methods accomplish the waterproofing in the center of the floor. The edges of the floor can be protective with a coving material up the wall and around pipe penetrations. That can be accomplished with Product #720 Epoxy Coving Resin System which can be used to install an integral cove base for all of our epoxy based mechanical room flooring and most of our other epoxy flooring and coating systems. This provides seamless wall to floor protection.

Choosing the Right Epoxy Sealer

May 18, 2015

Having the knowledge of which type of sealer to use is extremely important to the overall satisfaction of the job. There are 3 basic types of epoxy sealers. The first is 100% solids epoxy, solvent based sealants and finally water based sealers. There are also urethane and acrylic sealers.

To understand how each sealant works one must understand how they act as an epoxy. http://www.epoxy.com/primersealer.aspx . The 100% solids epoxy when applied to a floor retains a consistent thickness. Epoxy.com #15 http://www.epoxy.com/15.aspx is the best product for maintaining a clear epoxy sealer without any loss of thickness due to evaporation. If you roll a gallon of material on your floor, when it hardens you maintain the thickness of the full gallon of spread coverage.

Epoxy.com #15 can be used to seal previously installed epoxy and river rock stone on pool decks or walkways. It also seals Epoxy Chip flooring, as well as acts as a binger and sealer to Epoxy quartz flooring. It provides protection, just the right amount of shine and helps to keep the water from permeating the underlying concrete. It also works well inside in garages. It is our most versatile sealer that we offer it works great on concrete inside and when properly installed outdoors.

When you apply a water based sealer or solvated sealer you will consistently loose a percentage of the thickness due to evaporation. Even though this is the case there are times when a 100% solids epoxy may not do exactly what you need it to accomplish. In this case we offer products with different components and viscosity to suit your needs as a consumer.

Epoxy.com #671  is a low viscosity, two component, carbon filled, polyamide modified conductive primer/sealer formulated with special wetting agents to provide maximum penetration into concrete surfaces. Product #671 Primer Sealer is ideal for both new and old concrete surfaces. Product #671 Conductive Epoxy Primer Sealer provides excellent resistance to wear, and can be used either alone or as a conductive sealer or as a conductive epoxy primer when used with Product #674 Electro-Static Dissipating Urethane Topcoat and our Conductive Systems.

Epoxy.com #80 is a solvented clear acrylic solution formulated to create a clear, non-yellowing protective coating. Product #80 ACRYLIC SEALER http://www.epoxy.com/acrylic-sealer.aspx provides a tough, UV and abrasion resistant film that effectively protects surfaces from moisture penetration, staining, dirt, dust, and wear. It is good for both indoor as well as outdoor applications. This works well to seal existing terrazzo floors and as well as slate.

For those in California, who don’t want to use a 100% solid material, we offer Epoxy.com http://www.epoxy.com/High-Solids-Urethane-Coating.aspx Epoxy.com # 441 is free of the health and environmental problems normally found in solvent-based urethanes, while maintaining excellent performance properties. The very low VOCs allows this urethane coating to meet the strict low VOC standards. Epoxy.com # 441 Polyurethane Coating and Sealer provides a matte finish. Product #441 water-based urethane coating and sealer has good chemical, stain, and mar resistance.

Finally the most important thing to remember when you are choosing an Epoxy.com Sealer is to make sure you are using The Right Product for The Right Job. If you would like assistance with your selection please call our Technical Support Line at 352-533-2167 and we will be happy to assist you.
