How much does Eldorado stone weigh?

Can Eldorado Stone be used behind or around a fireplace?
Yes, Eldorado Stone has a zero rated combustion level, however you should not use the product inside the fireplace. Use kiln fired bricks if constructing an outside fireplace or fire pit.

What about corners?
All profiles and colour choices come with a pre formed 90 degree corner stone. Corners are measured by the lineal meter and come packaged in separate boxes to flat stones.

What does Eldorado Stone stick to?
Eldorado stone can be applied to concrete blocks, bricks or an approved sealed fibre cement board. See detail drawings and contacts of approved and recommended suppliers of the required fibre cement board in technical section.

Does Eldorado Stone come in panels?
No (except Stacked Stone), in order to create a truly realistic finish and to avoid noticeable panel shaped joints, each stone is individually crafted and coloured to give it its own unique form. The pieces are flat backed to assist with speed and ease of laying but a skilled craftsman is still required to piece together the “puzzle” and ensure a truly realistic and detailed finish.

What is Eldorado Stone stuck on with?
Eldorado Stone is fixed with a sand/cement mortar mix. Care should be taken to use a compatible range of products incorporating the sealing of the substrate and fixing of the stone. E.g HARD AS ROCKS SBR Latex is an additive that when used in standard cement and sand mortar mix (per manufacturers specifications) can offer many solutions including added strength, flexibility, water resistance, a bonding agent and freeze thaw resistance etc. It can also be used to waterproof the substrate. Please see manufacturers specifications.

Will the colours fade?
Only permanent mineral oxide colours are used. Eldorado stone offers a 50 year limited warranty restricted to manufacturing defects (when used on structures that conform to local building codes and when installed by a licensed applicator). In addition, Eldorado Stone is the only known stone veneer to have conducted extensive UV testing, which is essential under New Zealands harsh climate.

What is Eldorado Stone made from?
Eldorado Stone is manufactured from lightweight aggregates, Portland Cement and mineral oxide pigments.

How much does it cost?
Prices will vary depending on the profile, quantity and type of application. Please check with your local distributor or contact us for up to date supply and supply and lay rates.

How is Eldorado Stone packaged?
Eldorado Stone is pre packed into convenient sized cardboard boxes and stacked on wooden pallets. Quantities range from 1.1m2-1.3m2 per box of flats and 3lm - 4.4lineal meters of corners per box. All stone is sold by the box unless specified by your local distributor.

Can Eldorado Stone be used on water features?
Although the stone can be used on a water feature, it is not recommended that the stone be installed below the water line and where it may come into contact with any chemicals such as chlorine as this may void the warranty. The substrate needs to be completely watertight prior to stone installation.
