China construction materials exterior wall fireproof
Green Sandstone Wallboard
Mega green sandstone wallboard is made of inorganic mortar on the top and ceramic board on the bottom (inorganic resin plate, i.e. fiber cement plate, also called calcium silicate board, is optional for internal wall) with Mega’s patented technology and advanced equipment, compounded under low temperature condition. It possesses texture and appearance of natural sandstone, and is free from stain, blackening, moldiness of natural sandstone caused by high water absorption. It is suitable for gluing, wet cladding and dry cladding. | ||

| Australian Sandstone VS Mega Sandstone | ||
| Feature | Australian Sandstone | Mega Sandstone |
| Texture and Color | Natural color and texture, but big color variation of the Sandstone from different stone mines,installation effect is not uniformed. | Natural color and texture, small color variation of the Sandstone from different boards, installation effect is uniformed |
| Stain resistance | A lot of pinholes make it high water absorption and easy to collect microorganisms, which cause it to darken or get moss, reduce its durability. | The surface is made of Inorganic facing materials,processed by Mega's patented techniques, giving it good self-clean and stain-resistance capacity and durability |
| Installation | After cutting into boards, it's sandy and smooth,making it not suitable for gluing for safety concerns, but high cost for dry cladding. | Mega's Sandstone board is made of Inorganic facing material compounded with ceramic composited plate as a base. The embossed base is strong, and suitable for gluing |
| Environment | Severe damage to the natural environment during the mining process. | No damage to the Nature as it is not exploited from stone mines |
| Price | High price due to the high cost of mining and low yield rate. | Money efficient and affordable due to mass production and lower comprehensive cost |
