What is composite marble made of?
Composite Marble is 90-96% Calcium Carbonate (CaCO3) and 6-10% resin + pigments and a few other chemicals.
How is composite marble made?
Composite Marble is mixture is cast into blocks that are kept in open under the sun for a few days to dry off. The dry block is then sawn into slabs by gang saws. The slabs are then put into an automated line polisher for sizing and polishing.
Why should I use Composite Marble instead of natural marble?
Composite Marble is more dense and hence stain resistant. It is harder but not brittle, so we can get hairline thin joints that everyone aspires for but cannot get in natural marble; since it
comes in standard sizes (3040 mm x 1250 mm) no trimming etc. is required which in turn means less wastage and less cost; also, composite marble is man-made, hence devoid of any cracks or irregularities, it requires no resin filling, is consistent and requires less maintenance than natural marble.
In what thicknesses is composite marble available?
Here are a few tips to follow:
- Never use POP (Plaster of Paris).
- Use a high speed cutting machine with a good quality cutting blade
- Use good quantity of water during cutting
- Remove the plastic covering before installation or cutting, the covering is only for protection during transit.
- Preferably use adhesives instead of conventional cement mortar.
- Leave a gap of 5-8 mm underneath the skirting to counter any structural movement and thermal expansion
- It is mandatory to leave an expansion gap of 8-10mm every 5 meters wherever the expanse is large.
- The joints should not be filled immediately. Wait for the bed to dry and then fill up the gap with a high quality resin.
- Never use dark composites on the exteriors, the pigments are not UV protected.
- Use a good quality sealant on textured surfaces before and after installation.
- To clean the composite surface use lukewarm water or some good quality stone cleaner. DO NOT use phenyl or Harpic kind of cleaner, it will stain the surface permanently.
- Composite piece should not be more than 5 feet in length and 3 feet in width on floors.
Can we get textures on composite marble?
Yes. Sand blasting, Shot Blasting, Lupato, Leather and all kinds of CNC or Water Jet finishes can be done on composite marble. It is good for inlay work as well.
Where all can we use composite marble? Is it advisable to use composite marble on facades and exteriors?
Light colored composites can be used anywhere, interior or exteriors. Dark composite marble should be used only in interiors. If one opts for textured composite marble on facades, exteriors or interiors, it must be sealed first.
