Imperial Blue Sada Polish

Stoneza — Anantay Exports Pvt. Ltd. — is a quarry-direct manufacturer, processor and exporter of Kota limestone, operating from Bhilwara, Rajasthan since 1992. We operate quarries at Bijolia, Kota and Asind alongside verified direct quarry networks across India, processing and calibrating every order through our in-house factories in Bhilwara with zero middle trader markups. We supply pan-India and export worldwide.

Send the quantity, the finish and thickness you need, and the delivery location. We come back with a firm quarry-direct quotation and a confirmed lead time. Thickness and finish options are confirmed at quotation stage. Because we quarry and process ourselves, the quotation comes from the works rather than through a trader — and we would rather quote against a real drawing than hand you an indicative range that changes later.

Kota Blue is the quarry and trade name; Imperial Blue is our name for it. The spec code is STZ-FO-IMPE-SADA. Quote the spec code on a BOQ rather than either name — the same stone is sold under several names across India, which is exactly how substitution happens on site after a specification is approved.

A clean, even polish that deepens the colour and returns light without turning the surface into a mirror. The standard interior finish across most of our range. Progressive abrasive polishing to a medium-fine grit, stopped before the high-gloss stages. Shorter than a mirror process, which is why it costs less and keeps a slight softness. Wet grip: low — keep dry. Enough sheen to look finished, enough restraint to survive daily traffic without showing every mark.

Damp-mop with a pH-neutral cleaner. Avoid descaling and citrus products on limestone and marble. Re-polish in place when it dulls, which in a house may be never and in a busy corridor may be a decade.

Size: 22"×22" | 46"×22" | 2'×2' | 4'×2' | 3'×3' | 4'×4'. Thickness: 20 MM calibrated. Supplied machine cut / box pack at approximately 4.5 kg per sq ft. Custom sizing is available on project orders — send the setting-out and we will cut to it.

Yes. At 0.5-1.5% water absorption and 2600 kg/m³ density it is exterior grade. At under 1% absorption it needs no sealer and handles monsoon and wet areas without difficulty.

Yes. We export worldwide from Bhilwara with container loading, export packing and documentation handled in-house. Minimum order is project-based rather than a fixed count. For bulk and wholesale enquiries, container quantities and repeat programmes, send the schedule and we will quote FOB or CIF against it.

Yes, and we would rather you did. Ask for a wet sample as well as a dry one — every stone darkens when wet, some dramatically, and it is the one thing a photograph cannot show you.

Imperial Blue is kota limestone. Measured: water absorption 0.5-1.5% (low), density 2600 kg/m³, weight ~85-110 kg/sq m laid. At 0.5-1.5% (low) this is a low-absorption stone, which is why it needs no sealing and performs well in wet areas and through a monsoon.

Impregnating sealer recommended Use a breathable impregnating sealer, never a film-forming one. A film traps moisture inside the stone, and in Indian conditions it eventually clouds and lifts, at which point it has to be stripped. An impregnating sealer sits in the pores and lets the stone dry out. Reapply at the manufacturer’s interval, typically every few years on an exposed elevation and less often on a sheltered one.
