Q: Are custom colors available?
A: Depending on quantity ordered, custom colors are available in a case by case scenario.

Q: Are color blends available?
A: Proportioned color blends are not currently available but can be achieved by combining multiple different colors of the same style.

Q: Does Winter Valley have color variations?
A: Expect the color to have slight variations of off-white. This is not a monotone color. Per the Install Guide, make sure to blend multiple boxes together before installation.

Q: Can I blend multiple styles together?
A: It is possible to blend certain styles that we offer. The National True, District View, and Monument Gate styles can be blended. The Capital Sky style is a pre-made style blend as it is a split of National True and District View. The Georgetown Run style can NOT be blended with any other style.

Q: Do stone colors vary from box to box?
A: Colors may vary from box to box as the hues will remain constant while accents change. We always recommend mixing multiple boxes together during installation for the best results.

Q: How do I wash my Evolve Stone?
A: We recommend taking a soft-bristled brush and mild dishwashing soap to clean the surface of Evolve Stone. Avoid harsh cleaning products as they can contain harmful ingredients that could alter the appearance of the stone.

Q: Can Evolve Stone be power washed?
A: While the Evolve Stone material can handle a lower pressure setting at a conservative distance, the substrate could become damaged in the process which could affect the lifespan of the installation.

Q: Are backs of the stone perfectly flat?
A: Because of the nature of our material, the backs of the stones are not always flat. This is normal and should still allow for proper installation.

Q: Is a WRB (Water Resistive Barriers) and Rainscreen required for interior applications?
A: No, if the stones are inside and face no exterior conditions. We suggest the substrate be a black or grey color, so the substrate is not highly visible if there are seams between the stones.

Q: What if some stones are broken in the box?
A: Broken stones can still be easily used during the installation. Set aside any broken pieces until they are needed in areas where cuts are needed. If the box has an excessive number of broken pieces, please contact Evolve Stone directly.

Q: Is there a preferred substrate color?
A: Black or grey. The dark colors will be able to hide any seams that might appear after installation is completed..

Q: What is the thickness of Evolve Stone?
A: Stones vary in depth between 3/8" to 1 ¼" thick with a median thickness between 5/8" and ¾". Surface angulation helps maintain natural texture and depth.

Q: How is Evolve Stone installed?
A: In most cases, Evolve Stone installs using a finish nail gun and stainless-steel finish nails. Some substrates may require an alternate installation method. Click here to download detailed install guide.

Q: Should I blend multiple boxes together?
A: Yes, it is recommended that you open multiple boxes at a time and blend the contents together before installation.

Q: Does it require any special installation training to use Evolve Stone?
A: No special training is required. All that we ask is that you read our installation instructions thoroughly and watch our instructional videos before beginning.

Q: Do the finishing nails need to hit studs?
A: No, they do not. For the best results, we ask that you follow the nail pattern requirements in page 5-6 of the Installation Guide.

Q: Are specialty tools needed?
A: In most cases Evolve Stone uses standard wood working tools to install. Tools listed on page 3 of the Installation Guide.

Q: Do I need a special cutting blade?
A: A general cutting blade works. Use a carbide blade if lots of cuts are required.

Q: Do I need to order more than my project requires to account for waste and breakage?
A: Evolve Stone has minimal waste/breakage, so it is recommended that an extra 3% be ordered just in case.

Q: Can Evolve Stone be installed in areas prone to water such as a basement stairwell?
A: Yes, it can. Please note that areas prone to water contact can leave minerals and dirt behind on the surface of the stone through prolonged exposure and evaporation. If this occurs, clean the surface with soap and water using a light-bristled brush. If a film remains, use a product such as Thompson Water Seal to restore vibrance. Keep in mind the drainage/drying gap should always be maintained.

Q: What type of adhesive should I use for exterior installation?
A: It is recommended that an STPE adhesive system be used such as Tremco TremGrip adhesive with Tremco Vulkum 171 primer. The primer should be used on both the substrate and the back side of the stones. The adhesive should be applied in vertical beads to the backside of the stones only. We recommend testing a few stones before completing the installation. Watch the how-to video.

Q: How much adhesive should I order?
A: A general rule is (3) to (4) 10oz tubes of Tremco TremGrip per box of stones. One quart of Vulkum 171 is recommended per (10) to (12) tubes of adhesive.

Q: What screws do you recommend for sills over OSB/Plywood?
A: Self tapping stainless steel trim finish head screws are recommended. 3.5" or 4" length. Look at GRK Finishing Trim Head Screws.

Q: How do you recommend installing sills over concrete?
A: We recommend using vertical beads of adhesive with a galvanized "L" bracket like a Simpson A21 installed on the bottom of the sill and the wall. Two brackets should be used per sill.

Q: What is Fire-Rated?
A: Evolve Stone offers a Class-B Fire-Rated version of our products. It is designed to meet code requirements for interior installations. Please note that Fire-Rated does NOT mean fireproof as it is still considered combustible.

Q: Can the product be installed behind a wood stove or around a fireplace?
A: Yes, our Class B Fire-Rated product is highly resistant to flame spread, but it is still considered combustible. It is critical to check with the wood stove/fireplace manufacturer's guidelines and your local authorities' fire codes/regulations and requirements.

Q: Can high-strength cellulosic fiber board be used?
A: No it can't. For exterior applications we require a 7/16" minimum OSB or Plywood.

Q: Can the product be used as a kitchen backsplash or in a shower?
A: Yes, Evolve Stone can be used as a kitchen backsplash or shower. However, repeated exposure to water or other cooking items can result in mold/surface staining due to the natural surface textures trapping these particles. Refer to the above FAQ regarding how to properly clean Evolve Stone. 

Q: Can Evolve be used over a concrete foundation?
A: Yes, it can. The two methods for installing Evolve Stone over a concrete foundation are:
Fur-Out: covered on page 12 of Installation Guide. Watch the how-to video. (Evolve Stone's preferred method)
Adhesive: covered on page 9 of Installation Guide. Watch the how-to video.

Q: What length and type of finish nail should I use?
A: Finish nails should be long enough to penetrate ¼" through the back of the structural sheathing. Finish nails should be 304 grade stainless steel for standard exterior installation. In the case of coastal environments or area with high concentrations of salt in the air, 316 grade stainless steel is recommended.

Q: What type of finish nail should I use?
- For Interior installation we recommend galvanized finish nails. 
- For Standard Exterior conditions we recommend 304 grade stainless steel. 
- For Extreme Exterior conditions such as coastal environments or areas with corrosive airborne particles we recommend 316 grade stainless steel.
 

Q: How many finish nails should I purchase per square foot of stone?
- Georgetown Run - minimum 10 to 12
- District View - minimum 20 to 22
- Capital Sky - minimum 13 to 15
- National True - minimum 7 to 10
- Monument Gate - minimum 7 to 10

Q: The outside corner stone has a "wobble". What can I do?
A: From time to time the wall itself or the actual corner piece can be out of square. To fix this, apply a few vertical beads of exterior caulk or exterior adhesive (this will act as a shim) to the low side prior to pin nailing.

Q: Can stone size heights vary from corner stones to field stones?
A: Height of corner stones may be slightly taller than field stones at times. Adjust corner stone height before installing as needed or use guidelines to help split the size difference.

Q: What Water Resistive Barriers (WRB) can I use?
A: Water resistive barriers (WRB) must comply with ASTM E2556 Type I or Type II. Make sure the WRB is installed correctly, meets code, and the system is water tight and weather resistant.

Q: Can a Drainable Housewrap be used as both a WRB and Rainscreen?
A: No, it cannot. Drainable house wraps do not provide the necessary gap with Evolve Stone to allow for water to drain and can become trapped against the structure. Over time, this trapped water can cause damage to the structure.

Q: Can the product be in contact with the ground?
A: Yes. That said, make sure that your substrate is appropriate for ground contact and that drainage is impeded in no way.

Q: Can I put Evolve Stone over drywall or sheetrock?
A: A direct attachment to drywall/sheetrock is not recommend as you would have a low withdrawal strength . We recommend fastening ¼” Luan board, 3/8” OSB, or ½” plywood to the studs and painting the substrate black/dark grey. If you need a level transition to an in-plane wall you can remove drywall/sheetrock and replacing it with OSB or plywood. Then, you can nail the stones to the wall using either a 16- or 18-gauge finish nailer with 1.5” – 2” galvanized nails.

Q: How light is Evolve Stone?
A: Evolve Stone weighs approximately 2 lbs per square foot. 

Q: How does Evolve Stone perform in harsh weather?
A: Per ASTM testing, the material shows no effects when exposed to salt spray during testing, shows no effects when exposed to freeze-thaw cycles during testing, does not retain water, has minimal expansion/contraction, is UV resistant, and performs extremely well under wind loading.

Q: What happens if it chips or breaks?
A: Evolve Stone is colored throughout so any chipped or broken pieces can be re-textured and be used in the installation.

Q: Is Evolve Stone ICC-ES listed?
A: Yes, our publication number is ESR3970 for Non-Rated products and ESL1247 for Fire-Rated products.

Q: How many square feet of stone comes in a box?
A: Below are the square footage amounts per box for each style we offer:

- Georgetown Run: 14.25 sq. ft.
- District View: 14.25 sq. ft.
- Capital Sky: 14.25 sq. ft.
- National True: 14.25 sq. ft.
- Monument Gate: 20.25 sq. ft.

Q: How much does a box of stone weigh?
A: 30 to 35 lbs.

Q: How many corners come in one box?
A: One box of corners contains 7 linear feet of coverage. For example, one box of corners will cover the ground to 7 feet high on a corner installation.

Q: How many sills come in a box?
A: 15 sills come in a box with each sill measuring 20” long. Therefore, one box of sills contains 25 linear feet of coverage.

Q: My shipment was damaged in transit, who do I contact?
