Polished stone and porcelain surfaces are among the most elegant and durable materials used in modern interior design. Whether it is polished marble flooring in a villa, granite countertops in a kitchen, porcelain tiles in a commercial lobby, or encaustic tiles in a decorative installation, these surfaces require the right protection to maintain their beauty and resist stains.

LTP MPG Sealer is a professional‑grade, colourless impregnating sealer designed specifically for polished and low‑porosity surfaces. Manufactured in the UK by LTP, a trusted brand in stone care and surface protection, this sealer penetrates deep into the surface to provide long‑lasting protection without altering the polished appearance.

This long‑form guide explores everything you need to know about LTP MPG Sealer — how it works, where to use it, how to apply it, and why it is one of the most reliable sealers for polished stone and porcelain.

WHAT IS LTP MPG SEALER?

LTP MPG Sealer is a colourless, solvent‑based impregnating sealer formulated for polished and dense surfaces such as:

Polished marble
Polished granite
Polished porcelain
Encaustic tiles
Decorative stone
Interior walls and floors
Kitchen worktops
Fireplaces

Unlike topical sealers that sit on the surface and create a film, LTP MPG penetrates into the pores of the material, forming an invisible barrier that protects against:

Stains
Oils
Grease
Dirt
Moisture
Everyday contaminants

Because it does not alter the surface finish, it is ideal for high‑end polished surfaces where maintaining the original appearance is essential.

HOW LTP MPG SEALER WORKS

Polished stone and porcelain have low porosity, which makes sealing difficult. LTP MPG Sealer is engineered with micro‑fine molecules that penetrate even the tightest surface structures.

1. Deep Penetration

The sealer absorbs into microscopic pores, forming a protective barrier below the surface.

2. Invisible Protection

Because it is colourless and non‑film‑forming, it does not change the polished appearance.

3. Stain Resistance

The impregnating barrier repels:

Oils
Grease
Food stains
Dirt
Moisture

4. Easier Maintenance

Treated surfaces are easier to clean and maintain.

5. Long‑Lasting Performance

Once cured, the sealer provides durable protection for years.

HOW TO APPLY LTP MPG SEALER

Proper application ensures maximum protection and a flawless finish.

STEP 1: PREPARE THE SURFACE

Before applying:

Ensure the surface is clean, dry, and residue‑free.
Remove factory waxes or old sealers.
Use LTP cleaners such as:
- LTP Porcelain Floor Tile Cleaner (for floors)
- LTP Stonewash (for walls)
- LTP Grimex (for deep cleaning)

A clean surface ensures proper penetration.

STEP 2: APPLY THE SEALER

Tools you can use:

Soft cloth
Applicator pad
Sponge

Instructions:

Apply a thin, even coat.
Allow the sealer to absorb.
Within 20 minutes, buff thoroughly with a clean dry cloth or buffing machine.
Ensure no residue remains on the surface.

STEP 3: SECOND COAT (IF NEEDED)

For more porous surfaces:

Apply a second coat using the same method.
Always buff well between coats.

STEP 4: DRYING AND CURING

Drying time: 4 hours
Full resistance: 3 days
Walkable after: 4 hours

Avoid:

High temperatures
Underfloor heating
Over‑application

If over‑applied, remove residue using:

White spirit
A small amount of sealer, then buff immediately

COVERAGE

Coverage depends on surface porosity:

10–30 m² per litre

Polished porcelain requires less product. Encaustic tiles may require more.

AFTERCARE AND MAINTENANCE

To maintain long‑term protection:

Use LTP Porcelain Floor Tile Cleaner

For routine floor cleaning.

Use LTP Stonewash

For walls and vertical surfaces.
