If the buying question is “How do I protect installed marble from everyday stains without changing how it looks?”, DUSH PROTEK+ is our first recommendation in this five-product comparison. The official DUSH page describes it as a high-performance impregnating sealer that creates an invisible barrier within marble and natural stone. Its published use case directly addresses oil, wine, coffee and water penetration.

That positioning is especially relevant to Italian marble floors, kitchen marble counters, dining areas, bathrooms and living rooms. These are the places where expensive stone is regularly exposed to spills, cleaning water, cosmetics, cooking oil and food. Instead of allowing those liquids to enter quickly, a correctly applied penetrating sealer is intended to slow or prevent absorption so the user has time to wipe the surface.

Why PROTEK+ is our top general sealer recommendation

PROTEK+ has a simple buyer benefit: it is meant to protect the stone while remaining visually invisible. That makes it easier to recommend for premium marble where the natural colour, polish and veining are the main reason the stone was purchased. The owner does not normally want a decorative layer that changes the finish; the owner wants protection that stays out of sight.

The current DUSH page publishes coverage of 8–12 sq.m/L, an invisible finish, oil- and water-repellent protection and suitability for marble and natural stone. DUSH also states that the treatment should be applied to a clean, dry surface, allowed to penetrate and then wiped so unabsorbed excess does not remain on the top.

Who should choose PROTEK+?

• Homeowners with Italian marble flooring
• White or light marble owners who want invisible protection
• Kitchen and dining-area stone where food spills are common
• Bathroom marble exposed to water and personal-care products
• Hotel or commercial stone where easier daily maintenance matters
• Customers comparing an anti-stain sealer for marble in India

How should PROTEK+ be applied?

The official product guidance emphasises surface preparation. The marble must be clean and dry. DUSH describes application with a microfibre cloth, allowing approximately 20–30 minutes for penetration and wiping away unabsorbed excess. The page also states that full protection develops after the curing period and the floor should not be wetted too early. Always check the latest TDS before working because stone porosity and site conditions affect the process.

A patch test is important. Even when a product is designed to be invisible, premium natural stone varies from slab to slab. Testing an inconspicuous area lets the installer confirm absorption, residue removal and finished appearance before treating the entire room.

Some marble protection problems must be addressed before the slab is laid. If a project has not yet reached installation and the concern is rising humidity, soluble salts or moisture movement from the substrate, DUSH HIDRO SST is the relevant product in this guide. DUSH describes HIDRO SST as an all-six-side sealer for marble, granite and natural stone.

“All six sides” is important. A marble slab has more surfaces than the polished face that the customer sees after installation. The back, edges and top can all become pathways for moisture movement. Pre-installation treatment is intended to create protection around the slab before it becomes inaccessible inside the finished floor.

What problem does HIDRO SST address?

The main DUSH positioning is protection against rising humidity and salt. When moisture moves through bedding materials and porous stone, dissolved salts can move with it. As moisture reaches the surface and evaporates, salts may become visible as deposits or patches. On dark stone these light deposits can be particularly noticeable; on white marble moisture movement can create other appearance and maintenance concerns.

The key point is timing. A top-side sealer applied after the floor is finished is not the same as a six-side pre-installation treatment. HIDRO SST belongs earlier in the workflow. That makes it especially relevant to architects, stone contractors and homeowners planning a new installation rather than trying to repair a completed floor later.

Who should consider HIDRO SST?

• New marble flooring projects
• Italian marble before laying
• Black or dark marble where white salt marks would be highly visible
• Granite and natural-stone installations
• Projects concerned about rising humidity
• Projects where preventive protection is preferred to later restoration

Basic application concept

DUSH guidance for HIDRO SST describes applying the product undiluted to the required surfaces of the slab, allowing penetration, wiping excess and using a second coat according to the stone’s porosity. The DUSH white-marble care guide states that the treated marble should be allowed to dry before laying. This is a technical installation step, so the current TDS should be treated as the controlling document.

Do not confuse preventive sealing with fixing an existing moisture problem. If a completed floor already has active moisture coming through the substrate, the cause needs to be diagnosed. A new top-side application cannot automatically correct every issue underneath an installed slab.

Not every premium stone surface is polished to a mirror finish. Honed marble, brushed granite, sawn stone, flamed finishes and tumbled natural stone are deliberately less reflective. These finishes can look elegant and architectural, but the same texture can make the colour appear flatter than it would on a polished surface.

DUSH WET SEAL is formulated for that exact visual problem. Its current official positioning describes it as a penetrating colour enhancer and sealer for honed, sawn and textured natural stone. Instead of creating an artificial glossy film, it is intended to enrich the natural colour while simultaneously adding protection.

Why is WET SEAL different from an invisible sealer?

An invisible sealer tries not to change the appearance. A colour-enhancing sealer intentionally changes colour depth. That distinction should be made before the customer buys. If the customer loves the exact pale tone of a honed limestone or marble and does not want it to darken, WET SEAL may not match that design goal. If the customer feels the honed stone looks dry, weak or washed out and wants the natural pattern to become richer, WET SEAL is a much more relevant product.

The official product page publishes coverage of 8–12 sq.m/L and identifies the finish as colour-enhancing. DUSH also states that it works on honed, sawn, brushed, flamed and tumbled natural-stone finishes and provides water- and oil-repellent protection while improving colour depth.

Where can WET SEAL be considered?

• Honed marble floors
• Honed marble walls
• Brushed granite
• Sawn limestone
• Textured natural-stone paving
• Tumbled stone
• Architectural feature surfaces where colour looks too flat

How is WET SEAL different from WET LOOK?

Both products enhance colour, but they should not be treated as identical. WET SEAL is specifically positioned for honed, sawn and textured surfaces and emphasises colour enhancement without creating artificial surface gloss. WET LOOK is positioned for dark marble, granite and slate where the customer actively wants a more pronounced wet/gloss appearance.

That product separation is valuable for SEO and for buyers. Someone searching “best sealer for honed marble” has a different intent from someone searching “wet look sealer for black granite.” The DUSH range answers both searches with different products.

Dark stone is purchased for depth. Black granite, dark marble, slate and green or deep-coloured natural stone can look dramatic when their colour is saturated and the veins are clear. Over time, surface wear, incorrect cleaning, deposits and loss of reflective quality can make those stones appear grey, dry or washed out.

DUSH WET LOOK is designed to intentionally deepen that colour. The official page describes it as a solvent-based impregnating sealer that saturates dark marble, granite and slate to recreate the vivid appearance associated with wet or freshly cut stone. It also adds stain protection and water- and oil-repellent behaviour.

Who should choose WET LOOK?

Choose WET LOOK when the design goal is enhancement, not invisibility. If you have black granite that looks dull even after cleaning, a dark marble floor that has lost visual depth or a slate wall that should look richer, a colour-enhancing sealer is more relevant than a transparent sealer designed to leave the colour unchanged.

DUSH publishes coverage of 6–10 sq.m/L, a liquid form, a wet/gloss finish and an area of use covering dark marble, granite and slate. The product page also identifies dark marble floors, black granite bathrooms and slate feature walls as applications.

Is WET LOOK suitable for white marble?

If the customer wants white or beige marble to remain visually unchanged, WET LOOK is not the first product we would recommend. It is deliberately designed to deepen colour. For light stone where the objective is invisible protection, PROTEK+ or NANO+ is a more logical starting point. This distinction should be explained clearly because a “stronger colour” is a benefit only when the customer actually wants a stronger colour.

Application considerations

DUSH instructs users to begin with a clean, dry surface free from incompatible old coatings or residues. The product is applied evenly, allowed to penetrate and any unabsorbed excess is removed. Colour enhancement can make variation more visible, so a patch test is especially important on dark or multi-toned natural stone.

A customer should never decide from a product photo alone. Test the actual stone. Dark natural stone can vary considerably in mineral composition, porosity and finish. A small trial provides a better prediction of final colour depth than a generic online image.

DUSH NANO+ is the nano-technology option in this comparison. Its current official page describes it as a nano-particle impregnating sealer for marble, granite and natural stone, with a natural or invisible finish and published coverage of 10–15 sq.m/L.

This makes NANO+ particularly relevant when the customer wants protection without an intentional wet-look effect. White, beige and natural-coloured stone are obvious use cases because a strong colour-enhancing treatment could move the appearance away from the original design intent.

What does nano protection mean for the buyer?

The DUSH positioning explains the product in practical terms: nano-sized particles penetrate the stone’s pore network and create a hydrophobic barrier. The buyer does not need to become a chemist to understand the value. The important buying question is whether the product provides the desired stain and water repellency without changing the visible stone finish.

DUSH states that NANO+ repels water, oil and common household stains, maintains a natural/invisible appearance and can be used on marble and granite. Its official page publishes an MRP of ₹3,700 and coverage of 10–15 sq.m/L.

NANO+ vs PROTEK+

Both products are relevant when invisible protection is wanted, which means the comparison page must avoid pretending they are identical. PROTEK+ is our top general anti-stain recommendation because its public positioning directly emphasises premium anti-stain protection for all marble and stone, including oil, wine, coffee and water. NANO+ is the nano-technology alternative with higher published coverage and an accessible published price point.

For an important or expensive project, the right answer should come from the exact stone, expected staining risks and current TDS rather than from choosing solely on coverage or bottle price.

Who should consider NANO+?

• White marble requiring an invisible finish
• Beige marble and light natural stone
• Granite where colour change is not wanted
• Homeowners searching for a nano sealer for marble
• Projects comparing cost per litre and coverage
• Natural-stone areas requiring water- and oil-repellent protection
