What Is the Difference Between Protek+ and Densi Max Ultra?
Both products protect marble from staining — but they work at different depths, at different stages, and are applied by different people. Understanding the difference between Protek+ and Densi Max Ultra tells you exactly which one your marble needs right now.
The difference between Protek+ and Densi Max Ultra is one of the most common questions Dush receives — and the confusion is understandable, because both are described as marble stain protection products. But they solve the same problem from completely different directions, at completely different stages of a marble floor's life.
Dush Protek+ is a penetrating impregnating sealer applied to finished, installed marble — by homeowners or contractors. It fills the marble's pores with a hydrophobic and oleophobic barrier that causes spills to bead up rather than soak in. It lasts 1 to 2 years and is renewed as needed. Dush Densi Max Ultra is a penetrating densifier applied at the 80-grit grinding stage during professional polishing — it chemically reacts with the calcium minerals inside the marble to permanently close the pore structure from within. Protek+ is a surface-applied, renewable sealer. Densi Max Ultra is a permanent, professionally-applied internal treatment.
Side by Side — Protek+ vs Densi Max Ultra
How Each Product Works — Depth of Penetration
Protek+ penetrates from the finished surface downward, filling pores near the top of the marble to create a renewable hydrophobic barrier. Densi Max Ultra is applied at the 80-grit stage when the pore structure is maximally open, penetrating much deeper and chemically reacting with the calcium minerals inside the stone to permanently close pores from the inside out. The depth difference is significant — Densi Max Ultra's treatment happens at a molecular level within the stone structure itself, not just at the surface pores.
Surface and near-surface pores — Protek+ fills these with a hydrophobic barrier. Spills bead up and can be wiped away before penetrating deeper.
Also closes surface-level pores as part of its deep treatment — the surface becomes part of the permanently densified layer.
Protek+ penetrates the top layer of pores but its reach is limited when applied to a finished polished surface.
Applied at 80-grit stage when pores are fully open — chemically reacts with calcium minerals to form permanent C-S-H crystals throughout mid-depth pore network.
Deep internal pores remain untreated. This is why Protek+ renewal is needed every 1 to 2 years as surface treatment gradually depletes.
Deep pores are permanently closed by the calcium silicate hydrate reaction — this is the foundation that makes Densi Max Ultra's protection last indefinitely without renewal.
Dush Protek+ — The Renewable Surface Sealer
Dush Protek+ is a high-performance impregnating sealer that creates an invisible, deep-seated barrier within marble and natural stone — stopping oil, wine, coffee, turmeric, and water from penetrating the surface. Once treated, spills bead up for easy cleaning. Applied with a microfibre cloth by the homeowner, it activates in 24 hours and protects for 1 to 2 years before renewal.
Dush Protek+

- ★Hydrophobic + oleophobic — repels both water and oil-based spills
- ★DIY application — microfibre cloth, no specialist equipment
- ★8–12 sq.m per litre coverage
- ★Protects against turmeric, wine, coffee, oil, water
- ★Safe for food contact surfaces once cured
- ★Suitable for all marble, granite, limestone, travertine
Dush Densi Max Ultra
- ★Permanent internal pore closure — reacts chemically with the stone itself
- ★Applied at 80-grit grinding stage — maximum depth penetration
- ★Professional polisher application — not DIY
- ★Never needs renewal — one application, permanent
- ★Clear, no surface film — no change to marble appearance
- ★Also reduces rising moisture pathway through the stone
- ★Applied in 3 to 5 coats at the grinding stage
Which Product for Which Situation
Choose Dush Protek+
The right product when:
- Your marble is already installed and polished
- You want to protect marble yourself without a contractor
- Your existing sealer has worn off and needs renewal
- You want protection against turmeric, oil, coffee spills at home
- You are applying to kitchen countertops, bathroom marble, or dining area stone
- You missed the Densi Max Ultra treatment at installation
- You want protection that can be renewed as needed
Choose Dush Densi Max Ultra
The right product when:
- Marble is being newly installed and will be machine polished
- You are specifying protection for a new project before installation
- You want permanent, never-renew protection built into the stone itself
- Your contractor will be grinding and polishing the marble on site
- You want to reduce rising moisture migration through the slab
- You are a polishing contractor specifying for a client
- Maximum lifetime stain resistance is the priority

🏆 Why the Best Protection Uses Both
Densi Max Ultra and Protek+ are not competing products — they are complementary layers of a complete marble protection system, each doing what the other cannot.
Densi Max Ultra at installation creates the permanent foundation: a deeply closed pore structure that makes the marble itself intrinsically denser, harder, and less absorbent for the entire life of the floor. This foundation cannot be applied after the marble is polished — it requires the 80-grit stage.
Protek+ on the finished surface adds a renewable active surface barrier: oil and water-repellent protection that causes spills to bead up immediately and gives you time to wipe them away. This is the layer that stands between daily life and your marble — and it is this layer that needs annual checking and renewal.
Used together: Densi Max Ultra permanently closes the pore structure from inside → Protek+ maintains an active hydrophobic barrier on the finished surface → spills bead up and are wiped away before they can reach even the reduced pore structure beneath. This is the complete protection system for Italian marble in Indian kitchens, dining rooms, and bathrooms.
