Crystallization is a chemical-mechanical finish: a crystallizing compound is buffed into marble with a slow-speed machine and reacts with the calcium carbonate in the stone to form a harder, glossier surface layer. Silicate treatment uses a silicate-based compound that fills surface pores and hardens the top layer, giving gloss with more depth and less powdering on older stone.
Both are finishing passes, not repairs. Crystallization gives a bright, glass-like surface quickly and is the standard maintenance finish for marble in homes and hotels. Silicate treatment usually lasts longer on porous or aged stone because it closes pores rather than only reacting at the surface. Neither can level an uneven floor or remove deep scratches - for that see diamond grinding.
In a home, 12 to 24 months of normal use. In a shop or hotel lobby, 4 to 8 months. Lifespan depends more on cleaning habits than on the treatment: acid cleaners and hard-water mopping dull a crystallized floor within weeks.
Crystallization typically costs Rs.6 to Rs.10 per sq.ft and silicate treatment Rs.12 to Rs.18 per sq.ft in Delhi NCR. A combined clean-and-finish job is cheaper per sq.ft than booking the steps separately.
Crystallization cannot remove etch marks deeper than the reaction layer, cannot change the colour of the stone, and will not hide lippage. On a heavily scratched floor it traps the scratches under a glossy film, which looks worse under light.
Is crystallization safe for all marble?It suits most Indian and Italian marble. Very soft or resin-filled engineered stone needs a test patch first.
Does it make the floor slippery?A freshly crystallized floor can be a little slicker when wet, so an anti-slip treatment is available where required.
Crystallization or powder polish?Powder polishing uses a micro-abrasive to lift light haze and fine scratches. Crystallization adds gloss and surface hardness. Many jobs use powder first, then crystallization.
