Frequently Asked Questions about Stone Cladding

Why is eldorado stone® considered the most believable architectural stone veneer in the world™?

Believability. It’s the most important ingredient of Eldorado Stone and the most compelling reason why so many architects, builders and homeowners choose Eldorado Stone. Eldorado’s distinct process handcrafts moulds and creates the natural colour palettes that capture all the nuances of real
stone. The warmth and richness of Eldorado Stone creates unique spaces of permanence, romance and beauty; inside and out.

What is the difference between manufactured stone veneer and natural stone?

Manufactured stone veneer is cast from moulds of real stone which makes it lighter than natural stone. Natural stone may require wall ties and footings, which, in turn, can increase installation cost and difficulty. Eldorado’s architectural stone veneer is lighter weight, designed to adhere easily to a variety of structurally sound surfaces, and is capable of installations that would normally be very difficult and costly to achieve with natural stone. 

What are the benefits of using manufactured stone?

Installed, manufactured stone is approximately 1/3 to 1/2 the cost of natural stone. Its light weight properties eliminate the need for wall ties or footings. Manufactured stone has a 2% (approximately) waste factor versus 10% or more for natural stone. 

Where can I install Eldorado stone?

Eldorado Stone can be applied to any structurally sound surface with the proper preparation. It fits nearly any building plan — large or small, interior or exterior, new residential or commercial projects — or on any remodel.

Can I install Century Stone Cladding myself?

In general, installation of Century Stone can be installed by almost anyone. However, installation does require a fundamental understanding of stone masonry. 

How does Eldorado Stone Cladding withstand freeze / thaw cycles?

Eldorado Stone products are tested for freeze /thaw durability. As with any installation, making sure to incorporate good building practices that include proper flashing and water diversion techniques will help ensure a successful installation. 

How much does Eldorado Stone Cladding weigh?

Approximately 45Kg per m².

Will Eldorado Stone Cladding fade?

The base color is blended throughout and permanent mineral oxide pigments are applied and absorbed when the veneer is cast. Color becomes an integral part of the veneer and, similar to natural stone, there are minimal noticeable color changes after years of weathering. 

How important is a good stone installation?

As with any building material, the beauty of that product is greatly enhanced by how well it is installed. With Eldorado Stone, careful consideration regarding the type of profile and color selected, the actual installed stone “pattern”, and the type of grout technique used, are all very important factors to regard. It is always best to create a mock up board with the desired aesthetic appeal prior to installation on your project. 

What type of coverage can be expected?

Approximately 8m². This varies depending upon the stone type used and the installers ability. Stacked Stone, for instance, sold in 100mm modular component panels, is easy to install and will provide coverage of up to 16m² in a day.

Is Eldorado Stone Cladding combustible?

No. Eldorado Stone’s listing by Underwriter’s Laboratories shows zero fuel contributed and zero smoke developed. It can be installed as a façade to fireplaces and behind stoves. It is recommended the product is at least 18" away from any direct flame. 

Can I install Eldorado Stone Cladding on overhead horizontal surfaces?

Please verify your installation with your building official and consult with an engineer for specific design issues on your project. There are grout and mortar manufacturers that will support their product’s use in these installations. Eldorado Stone’s 50 Year Limited Warranty will still cover our veneer products for manufacturing defects.

Can I install Eldorado Stone Cladding near water?

It is not recommended for use below the water line in a pool, a fountain or below grade. A high quality penetrating and breathable sealer that is either silane or siloxane-based is recommended in areas where the stone may be subject to frequent water run off.
NOTE: A sealer may affect the stone color and may create a gloss or matte finish. Always test a small area beforehand.

How thick are the stones?

35 - 45mm depending on the texture.

How do I clean the Eldorado Stone Cladding?

To clean dirt or other particles first try a simple soft bristle brush. If necessary use a granulated mild type of detergent mixed with water or a solution of (no more than) 1 part white vinegar to 5 parts water. Rinse with clean water to remove any cleaning solution that might remain on the surface. Never use wire brushes, acid cleaners, power washers, bleach, paint remover or any other type of concrete cleaner.

How do I clean efflorescence?

When efflorescence occurs, as it does with many masonry products, it is the usually the result of moisture migration through the masonry substrate. Once the moisture is on the masonry surface, it evaporates, depositing dissolved salts in the form of efflorescence. Efflorescence naturally disappears over time as long as the moisture source is controlled or eliminated. Efflorescence may be removed with a solution of 1 part white vinegar to 5 parts water. Scrub using a soft bristle brush and vinegar/water solution. Rinse well with clean water.

Can I seal Eldorado Stone Cladding?

It is not required to seal Eldorado Stone. A sealer will provide added protection and will usually be easier to clean if the surface becomes dirty. If you choose to use a sealer for added protection use only a silane or siloxane-based penetrating , breathable masonry sealer.
NOTE: A sealer may affect the stone color and may create a gloss or matte finish. Always test a small area beforehand.

Does eldorado stone require movement joints?

Expansion joints normally pass completely through a wall. Control joints normally are on the surface of the wall and relieve strain on the skin of the wall. Terminate the veneer installation where control and expansion joints occur in the substrate. Do not span these joints with veneer because this will lead to cracking. Expansion joints in a building must be specified by the architect or engineer.

How do I install Eldorado Stone Cladding when there is an expansion joint?

Treat each section as a “separate” installation. Do not span movement joints with the veneer.

Does eldorado stone need a ledge detail at the bottom for structural support or can it hang freely?

No footings or support ledges are needed. The product is an adhered veneer and is supported on the wall by the bond of the mortar to the stone and scratch coat.

What is the fire rating of eldorado stone?

Eldorado Stone has been tested for fire hazard and shows zero flame spread and zero smoke developed. Since Eldorado Stone is non-combustible there is no fire rating.

Can we install eldorado stone around a fireplace?

Eldorado Stone can be installed around a fireplace. The veneer has to be a minimum of 18" from any open flame. 

What measures should be taken for hot /cold weather installations?

For cold weather installations ambient temperature should be 4ºC or higher at the time Eldorado Stone veneer is applied.  Wall surfaces may need to be covered and heated after installation of veneer to avoid freezing the mortar.
