About XOP
We do not change the stone
by even a millimeter.
It does not block the pores; it coats only their inner walls.
So the look stays the same, and it does not peel.
Bones and face
Maintaining a building is
like caring for skin.
You do not put on sunscreen to strengthen your bones. You put it on to protect how you look. A building is no different.
A misunderstanding
Harder is not
always better.
Conventional hardeners are a technology that soaks into stone or concrete, fills the gaps, and sets hard. The aim is structural strength and prevention of carbonation. It is not a bad technology. But is what you own a bridge?
One more point. Because a hardener works by filling gaps and setting hard, the denser the material and the fewer its gaps, the less effect it has. On polished marble and granite, or on dense porcelain tile, the hardening effect is limited.
Why it works
With nothing to hold on to,
dirt cannot stay.
Penetration
Coats only the inner walls of the pores
It causes no chemical change in the stone. It does not seal the pores, so it does not peel.
Water- and oil-repellent
Water and oil both bead up and run off
The same principle as a Teflon pan or a lotus leaf.
Vapor permeability
Keeps rain out without stopping the material from breathing
No film over the surface. The stone breathes. It does not blister, and it does not peel.
How it differs from a film coating
What happens if you stretch
plastic wrap over your face?
Ultraviolet light
Even the sun that split a clothespin
cannot break this bond.
Ultraviolet light at the wavelength that can break XOP's bonds (250 nm) is blocked by the ozone layer and does not reach the ground. What reaches the ground is 280 nm and above. The 340 nm that breaks down ordinary organic coatings does reach it.
Efflorescence
Hardeners have a side effect.
The white powder that appears on an exterior wall is material from the stone, dissolved in water, carried to the surface, and hardened there. Dissolving, being carried, hardening. When these three come together, it appears. The white powder is only the tip of the iceberg.
Not claims, but measurements

Frequently asked questions
What materials can it be used on?
Stone (granite, marble, limestone, sandstone, terrazzo), tile (unglazed porcelain, stoneware, tile joints, terracotta), concrete, plaster finishes (Jolypate, shikkui lime plaster, diatomaceous earth plaster), fiber-cement siding, ALC panels, and similar materials. It can be applied where water absorption is 0.1% or higher.
About durability
More than 15 years of record on wall surfaces. Conditions of use differ by material and environment, so we advise after an on-site survey.
Will the appearance change?
Because it causes no chemical change in the stone and coats only the inner walls of the pores, the finish is designed not to alter the appearance significantly.
Do you go straight to full application?
No. We carry out a test application, confirm the condition, and then proceed with full application.
