ConcreteBase Coat (FBs101)

Anti-soiling self-cleaning solution for stone surfaces

Feibo stone self-cleaning coating uses nano photocatalytic and super-hydrophilic technology so stone surfaces clean themselves with sunlight and rain and stay bright and new for years.
It prevents water marks, mould spots and dust build-up, reduces cleaning and maintenance, extends stone life, protects the building’s image and supports greener, low-carbon cities.

ConcreteBase Coat
Product overview

Nano protective primer

Product features:

  • Stops pollutants penetrating water-based substrates such as concrete and stone
  • Anti-mould and antibacterial: reduces internal contamination and mould
  • Penetrating protection — no surface film, the natural texture is preserved
  • Colourless and transparent, no change to the material’s appearance
  • Combined with the nano self-cleaning coating for even better anti-soiling protection

Functions:

Waterproof, anti-soiling, anti-mould, anti-algae — lasting protection of the substrate’s internal structure

Typical uses:

Porous substrates such as concrete and stone — stops water and pollutants penetrating, extends service life

Main ingredients:

Organosilicon based

How it works

Functions and performance

Nano protection / penetrating barrier

Nano protection: the penetrating nano primer reaches deep into the micro-pores of stone, concrete and other porous substrates, forming a colourless transparent protective layer on and below the surface. It blocks water, oil and pollutants, preventing the efflorescence, mould and corrosion caused by water absorption.

Penetrating barrier: the primer does not change the material’s appearance and keeps its natural texture, while being “breathable but waterproof” — moisture inside the substrate can escape while pollution cannot get in, for lasting protection.

1 · Photocatalytic self-cleaning substrate + organic dirt sunlight activates TiO₂ dirt broken down 2 · Super-hydrophilic self-cleaning loosened dirt rain sheets under the dirt dirt washed away Both effects together • Light breaks organic dirt apart• Water contact angle drops sharply• Rain spreads into a sheet, not beads• The sheet lifts dirt off the surface• No polishing, no detergentsSunlight + rain = clean surface

Photocatalytic / super-hydrophilic self-cleaning

Photocatalytic self-cleaning: nano titanium dioxide in the coating develops strong oxidising power under daylight, continuously breaking down organic pollutants left on the stone (oil, mould) into harmless substances — self-cleaning plus antibacterial and anti-mould action.

Super-hydrophilic self-cleaning: the surface water contact angle is below 15°, so rain spreads into a sheet, gets under the dirt and washes it away. Natural rain does the rinsing — no lingering droplets or stubborn water marks, and the stone stays clean and bright long term.

Multi-layer protection · stone self-cleaning results

Left: untreated substrate
Porous materials such as concrete and stone absorb water; pollutants travel inside with it, causing mould, efflorescence and discolouration.

Centre: nano protective primer
After the primer, a penetrating protective layer forms inside the substrate, blocking water and keeping the interior dry and stable.

Right: primer + self-cleaning coating
With the nano self-cleaning top coat, the surface is super-hydrophilic and photocatalytic: rain carries dirt away for lasting anti-soiling, anti-mould and self-cleaning performance.

Why it matters

Industry pain point 1: GRC elements

  • GRC elements sit outdoors, collect dust and, after absorbing water, suffer efflorescence, mould and surface cracking

  • Uneven rain run-off leaves mud trails and water marks that spoil the appearance

  • Frequent cleaning with high labour cost, and pressure washing damages the surface coating

  • Without effective protection, element life shortens and maintenance cost rises

Why it matters

Industry pain point 2: building stone

  • Granite, marble and other stone are attacked by rain, exhaust and biological growth: surfaces blacken and stain

  • Stone is porous; once water gets in, mould and algae grow and are hard to eliminate

  • Cleaning facades or large stone relies on climbing or work at height — a safety risk

  • Frequent cleaning is costly and can accelerate ageing and dull the colour

Application process

How we apply it

We follow a standardised nano protective primer + nano self-cleaning top coat process that gives stone dual protection: “waterproof inside, self-cleaning outside”.

STEP 1

Site survey and feasibility

Our technical team surveys the stone substrate, confirms feasibility, assesses porosity, weathering and environmental conditions and prepares the application plan.

STEP 2

Sample and performance test

Before full-scale application a small sample area verifies the coating’s adhesion, waterproofing and anti-soiling performance on the stone.

STEP 3

Surface cleaning and preparation

Professional stone cleaners and equipment remove dust, stains, algae and old residue, leaving the stone clean, dry and oil-free.

STEP 4

Two-layer application (primer + top coat)

First the nano protective primer is applied evenly, penetrating the pores to form a waterproof barrier;
then the nano self-cleaning top coat gives the surface super-hydrophilic and photocatalytic functions — anti-soiling, anti-mould, no water marks.

STEP 5

Ambient curing

About 4 hours of natural curing forms a dense, transparent two-layer protective film without changing the stone’s texture or colour.

STEP 6

Testing and data collection

After application, waterproofing, anti-soiling and self-cleaning performance are tested to confirm the two-layer system, and an evaluation report is provided.
