INTRODUCTION

Marble polishing is one of the most important steps in stone restoration and maintenance. Whether in hotels, malls, villas, commercial lobbies, or residential spaces, polished marble requires periodic restoration to maintain its clarity, shine, and elegance. Over time, marble becomes dull due to foot traffic, micro‑scratches, embedded dirt, and chemical exposure. This is where Klindex Polish KP85 becomes essential.

KP85 is one of the most widely used marble polishing powders in the world. Manufactured in Italy by Klindex, a global leader in stone polishing technology, KP85 is engineered specifically for marble and calcium‑carbonate stones. Its unique blend of fine abrasives and chemical reaction agents produces a deep, reflective gloss while removing dullness, light stains, and embedded dirt.

This long‑form guide explains everything you need to know about Klindex KP85 — how it works, where to use it, how to apply it correctly, and why it remains the industry standard for marble polishing.

WHAT IS KLINDEX POLISH KP85?

Klindex KP85 is a professional‑grade marble polishing powder designed for:

• Marble
• Limestone
• Travertine
• Onyx
• Other calcium‑carbonate stones

It is not designed for granite, porcelain, ceramic, or glass (as confirmed by the official Klindex TDS).

KP85 works through a combination of:

• Fine abrasive action
• Chemical reaction with calcium carbonate
• Heat generated by the rotary machine

This combination produces a brilliant, mirror‑like gloss while cleaning the surface and removing light imperfections.

HOW KP85 WORKS

KP85 uses a dual‑action polishing mechanism:

1. Mechanical Abrasion

The fine powder contains micro‑abrasives that:

• Remove micro‑scratches
• Eliminate dullness
• Smooth the surface
• Enhance clarity

This prepares the stone for the chemical reaction.

2. Chemical Reaction

KP85 contains Potassium Oxalate and Oxalic Acid, which react with calcium carbonate in marble to form Calcium Oxalate, a harder and more reflective compound.

This reaction:

• Increases surface hardness
• Enhances gloss
• Improves durability
• Creates a long‑lasting shine

3. Heat Activation

The polishing process requires minimal water to generate heat.

According to the Klindex TDS:

• Too much water prevents the marble from heating
• Insufficient heat slows the polishing reaction
• Excess water dilutes the powder and reduces gloss

The correct technique is essential for optimal results.

HOW TO APPLY KP85 (ACCORDING TO KLINDEX TDS)

Correct application is essential for achieving a high‑gloss finish.

STEP 1: PREPARE THE SURFACE

• Clean the floor thoroughly
• Remove dust, dirt, and residues
• Ensure the surface is free from coatings or sealers

STEP 2: APPLY THE POWDER

1. Spread a small amount of KP85 on the floor.
2. Use a felt pad, Discolux pad, or white pad.
3. Add only the minimum water needed to form a dense mud.

Important Warning from Klindex TDS

Using too much water prevents the marble from heating, slowing down the polishing process.

STEP 3: POLISH THE SURFACE

• Work a small area at a time
• Use a rotary machine
• Move in overlapping passes
• Maintain a dense mud consistency

The heat generated activates the chemical reaction.

STEP 4: RINSE THOROUGHLY

After polishing:

• Rinse the surface with clean water
• Remove all powder residues

Critical Warning

Never leave KP85 on the surface without rinsing — it may remove the gloss.

STEP 5: DRY & INSPECT

• Allow the surface to dry
• Inspect the gloss level
• Repeat if necessary

COVERAGE

Coverage varies depending on:

• Surface condition
• Porosity
• Machine pressure

Typical usage:

Approx. 100 g per working area
