ErthCOVERINGS is the registered brand name for our extensive line of thin veneer natural stone products.
ErthCOVERINGS is made from 100% natural stone. There is no cement, colouring, molds or man-made materials added or mixed into the stone.
ErthCOVERINGS installed cost is usually much lower than the installed cost of natural masonry. ErthCOVERINGS require no footings, foundations, permits or preparation allowing for quick cost effective installation.
The average weight of ErthCOVERINGS is 8 to 14 lbs/sq.ft.
Brick ties are not required when the stone weighs less than 15 lbs per square foot. Most ErthCOVERINGS products weigh between 8 and 14 lbs per square foot, therefore brick ties are not required for most ErthCOVERINGS products.
ErthCOVERINGS do not require footings or foundations when installed on perimeter walls. When installed in the center of a floor however, the structural integrity of the floor should be examined. Starter strips securely fastened to the wall may be required when installation begins above the floor.
The average thickness of ErthCOVERINGS is 1/2" - 1 1/2".
ErthCOVERINGS are available in a range of styles and colours. Our stone types include slate, limestone, quartzite, sandstone, basalt, marble, and pebbles.
The natural colour of ErthCOVERINGS will weather just like any other natural stone. Previous installations have shown no change in colour after years of weathering in various climatic conditions.
ErthCOVERINGS are as good as the substrate they are applied to. ErthCOVERINGS will not break down in an interior or exterior application.
Yes. Aside from a few products that require sealing for exterior use or are for interior use only, almost all ErthCOVERINGS are suitable for interior and exterior applications.
ErthCOVERINGS are installed similar to tiles except ErthCOVERINGS require no grout joints. ErthCOVERINGS should be installed with staggered joints, similar to laying hardwood.
For interior walls only up to a height of 10′, ErthCOVERINGS can be applied to gypsum wallboard, gypsum plaster, or exterior grade plywood. For interior walls over 10′ high, cement board is recommended. For exterior applications, ErthCOVERINGS can be applied to brick, masonry block, cured concrete, cement mortars, or cement board.
Yes. ErthCOVERINGS products are easily cut using a wet saw with diamond tipped blade. Always use appropriate safety apparatus.
ErthCOVERINGS products are virtually maintenance free. Occasional washing to remove dust and dirt build-up is all that is required for exterior applications. Sealing of stone with a penetrating sealer is optional although some ErthCOVERINGS products must be sealed if you intend to install them outside.
A major benefit of ErthCOVERINGS is its lightweight feature. All that is needed to fix the stones to walls is appropriate mortar for fixing stone. Ensure exterior grade mortars are used for exterior installations.
ErthCOVERINGS can be applied over any structurally sound flat surface such as drywall, stone, block, brick, concrete, or cement board. A cementitious backing must be used for all exterior applications. Please see our details drawings in the resource section for more details.
For exterior applications over wood sheathing, the use of a weather resistant barrier (Tyvek, Typar, etc.) is required followed by a minimum 6mm rainscreen system such as Mortairvent. Please see our detailed drawings in our resource page for more details.
For all interior applications, and exterior residential applications, a polymer-modified mortar is used, such as Chembond 8820, Mapei Ultraflex 2, Flextile 52, etc. For commercial exterior applications, a polymer modified mortar with a latex additive is recommended, such as Flextile 51 with Flextile 43 Additive, or Mapei Kerabond/Keralastic.
ErthCOVERINGS have been designed to make installation almost seamless. Basic installation of ErthCOVERINGS will disguise the seams.
Most ErthCOVERINGS products are only suitable for walls however some ErthCOVERINGS products are suitable for floor applications. Discuss your options with your nearest dealer.
Yes. ErthCOVERINGS can be used around gas, electric, or wood burning inserts and fireplaces. Always refer to the manufacturer`s installation instructions and local building codes.
Yes. ErthCOVERINGS will perform the same as any natural stone.
No more than 10′ in height should be installed per day. Any length of wall however can be installed.
ErthCOVERINGS allow for quick installation. Anywhere from 100 to 1000 sq. ft. can be installed in a day`s work.
Ask your ErthCOVERINGS dealer for a list of installers who are experienced with the product. Alternatively, most tile setters or handy people can install ErthCOVERINGS considering they familiarize themselves with the full installation instructions.
