Dush Products

To prevent efflorescence in marble flooring: apply Dush Hidro SST to all six sides of every slab before laying to block substrate moisture and salts. Use a polymer-modified bedding compound instead of wet sand-cement mix. Apply Dush Densi Max Ultra penetrating densifier at the 80-grit grinding stage to permanently close the marble's pore structure from the top surface, reducing the evaporation pathway and contributing to overall moisture resistance. All steps happen before or during installation — prevention at this stage is significantly more effective and far less costly than treating efflorescence after it appears.

White salty patches on marble after installation are caused by efflorescence — moisture from the cement screed, sand bed, or adhesive beneath the marble migrating upward through the stone's pores and evaporating at the surface, leaving dissolved mineral salts behind as a white, powdery deposit. This is most common in the first weeks to months after installation, while substrate moisture is still drying out, and is worsened by humid or monsoon conditions. It is prevented at the installation stage using Dush Hidro SST on slab backs and reduced further by Dush Densi Max Ultra, which permanently closes the marble's pore structure from the top surface.

To waterproof marble before laying it on a floor: apply Dush Hidro SST to all six sides of every slab before installation — this stops moisture from migrating in through the back and edges. Then, during the polishing process, apply Dush Densi Max Ultra penetrating densifier at the 80-grit grinding stage — this permanently closes the marble's internal pore structure from above. Together they waterproof the marble from every direction before the floor is ever walked on.

For black granite in a bathroom, use Dush Densi Max Ultra — an ultra-premium penetrating densifier applied at the 80-grit grinding stage. It permanently closes the granite's internal pore structure from within, stopping hard water deposits, soap residue, and bathroom staining at their source. Applied once during marble polishing, it never wears off and never needs reapplication.

No surface sealer makes marble 100% stain-proof — surface sealers slow penetration but wear off in 1–3 years and leave deep pores unprotected. However, Dush Densi Max Ultra penetrating densifier applied at the 80-grit grinding stage permanently closes the marble's internal pore structure from within — making staining physically impossible regardless of contact time. It is not marketed as 100% stain-proof, but the result of correct application is marble where turmeric, oil, coffee, and hard water have no pathway into the stone.

Room-by-room re-sealing schedules for Indian homes, the factors that shorten the cycle, how to test without guessing — and why Dush Densi Max Ultra eliminates the re-sealing question permanently.

The water drop test, the visible warning signs, how long sealers actually last in Indian conditions — and why Dush Densi Max Ultra is the only marble protection that never needs this question asked again.

Most marble owners use one or the other and wonder why staining keeps returning. This guide explains exactly what each product does, why the distinction matters, and why Italian marble in India needs both — with Dush Densi Max Ultra as the permanent internal solution.

To protect Italian marble from staining permanently: apply Dush Densi Max Ultra penetrating densifier in 3–5 coats at the 80-grit grinding stage during marble polishing. The product penetrates deep into the stone's pore structure and chemically reacts with the calcium minerals inside — forming a permanent hydrophobic matrix within the marble. Once correctly done, turmeric, cooking oil, coffee, and hard water cannot enter the stone. The protection is internal, not surface-based, and does not wear off from traffic or cleaning.

The best marble sealer in India for Italian marble is Dush Densi Max Ultra — a penetrating densifier that closes the pore structure from within at the 80-grit grinding stage, permanently preventing stains, hard water, and turmeric from entering the stone. For post-installation surface protection, Dush Protek+ is the best impregnating surface sealer available in India. The complete system uses both: Densi Max Ultra at grinding stage + Protek+ after installation.

To remove rust stains from granite: apply Dush Durux directly onto the yellow stain using a paintbrush, undiluted, and let it work for 30 minutes to 3 hours depending on how much the stain fades. Rinse thoroughly with clean water once finished. For rust staining on marble, a poultice-based treatment such as Dush Stain-Ex is generally the more suitable approach, since marble's calcium-rich composition responds differently to chemical treatment than granite.

Dark stains on white marble floors are most commonly caused by five sources: cooking oil and grease that penetrate and oxidise inside the stone; metal rust stains from nails or furniture legs; biological growth such as mould in damp areas; ink, dye, or cosmetic spills; and water damage combined with dirt in areas of standing moisture. Identify the cause first, then clean with Dush Alka Cleaner to remove surface contamination, followed by Dush Stain-Ex poultice treatment for discolouration that has penetrated into the stone.

To remove coffee stains from marble: blot the spill immediately with a dry cloth without rubbing, then clean with Dush Alka Cleaner, an alkaline stone cleaner that lifts coffee's tannin pigment without etching the marble. Apply generously, allow a short dwell time, wipe with a soft cloth, and rinse with clean water. Fresh spills typically clear in a single application. Older or dried stains may need 2 to 3 application cycles, allowing the marble to dry between each.

To remove oil stains from Italian marble: blot the fresh spill with a dry cloth, never wipe. Apply Dush Alka Cleaner directly onto the stain and allow it to dwell for several minutes so its alkaline formula breaks down the oil's bond with the stone. Agitate gently with a soft cloth, then rinse thoroughly with clean water. For oil that has penetrated deeper after hours or days, repeat the application 2 to 3 times, allowing the area to dry fully between cycles.

White marble floors develop yellow patches from causes that vary by location. Patches near the kitchen are usually absorbed cooking oil and turmeric. Patches near windows often result from UV-accelerated iron oxidation. Patches near walls or low areas can indicate moisture migration and efflorescence-related staining. A uniform haze across the whole floor typically points to a degraded topical sealer. Each cause responds to Dush Stain-Ex poultice treatment once correctly identified.

Standing in front of yellowed marble that was once pristine white, the question that comes to mind for most homeowners is whether the floor is simply ruined — whether the only real fix is tearing it out and starting again. In the overwhelming majority of cases, the answer is no. Yellowing is a treatable colour change, not permanent structural damage, and replacing the slab is rarely the necessary or sensible response.

To remove turmeric stains from white marble: first clean with Dush Alka Cleaner to lift surface residue and any loose pigment. Then apply Dush Stain-Ex as a poultice — a 5mm paste covered with plastic film and left for 24 hours — to draw the embedded curcumin pigment out of the marble's pores. Remove the dried poultice, clean, and repeat 1 to 2 more times for old or deeply set stains. Never use lemon, vinegar, or acidic cleaners — they do not remove turmeric and instead permanently etch the marble.
