Answers to frequently asked questions
| What is different from European and American
products, which
already have shown satisfactory
results? |
When compared to foreign products, you will
note that these other products have indeed
shown satisfactory results.
This is because European and American architecture has used more stone materials than Japanese architecture.
Also, Japanese don't have the cultural habit of putting stone tiles on the floor and walking into a building without removing footwear.
However, when you compare the quality of stone materials made in Japan, it becomes clear that "thickness" is a big difference.
More thickness stone materials are, the more difficult it is for water to permeate the material. This leads to improved durability.
That is to say, the conditions for using stone materials in Japan are quite severe, and weather conditions are different compared to other countries.
We are working on products that have durability and last longer under severe conditions. (I think made in Japan products suit Japan best) |
| Does stone material really degrade? |
Yes, stone materials do degrade naturally.
Most of the cause is from organic substances
and acid rain permeating into the material,
but when moisture increases, algae and other
fungus grow, causing further degradation.
We use our company made stone temperament reinforcement (AD-HDST 2) to repair the rigidity of degraded stone materials.
This is a picture of how sandstone peels.
When water invades, the layer starts to peel
off just like Baumkuchen. |
| Can AD-COAT work on concrete? |
Yes, of course you can use it on concrete. AD-COAT is optimally used where you don't want the fluorine or urethane coating to come off, but want to prevent the stone from getting discolored or neutralized.
AD-COAT doesn't form a film, so it doesn't change the concrete's appearance, only protects it. |
| I want to apply it after cleaning exterior
walls. Is it possible to use it on tiles? |
We receive a lot of questions asking, "Can't be used after cleaning exterior walls?"
If the exterior walls and tiles are made of water absorptive materials, you can expect great results.In addition, by permeating into tile seams, it prevents them from discoloring or degrading.
After cleaning exterior walls, please consider applying AD-COAT. |
| We used water repellent, but it never worked! |
We've often heard this type of complaint from people who have used other company's products.
There are a lot of stone materials in the market and to try to cover all of them with one repellent is not advisable.
It is very important to choose the right coating for the right stone material.
If you say you've been using many products but none of them have worked, try AD-COAT, it really works. You'll see the difference.

| How long does it last? |
There is no official time period for Protection against water permeation.
We've experimented
with the efficiency and
have confirmed
that it lasts more than 10years,
however, because
of differing construction
conditions,
weather conditions, and other
points, such
as exterior or interior surfaces,
walls, floors,
the contents of the water
supply, etc.
We can't lump things together
and say how
long it will last.
Additionally, the evaluations differ according to their respective purposes.
For example,
if you used AD-COAT to reduce
the base material
degradation, when you look
at it over
the long term, the difference
between non-coated
and coated is obvious.
If you used it to prevent discoloring, you can expect a big difference between applied surfaces and not applied surfaces.
However, it should be noted that even when the water-absorption prevention layer still remains inside some material, it doesn't mean that discoloration will not attach to the surface.
Therefore, some people consider "efficiency to be over" when they see discoloration on the surface.

The picture on the left shows the concrete part, it's been three years since applying AD Super.

| What is the chemical used for protection
against water permeation? |
Chemicals for protection against water permeation is a product that permeates inside materials, such as stone materials and concrete, and forms a layer within those materials that has the ability to absorb water
As a result, it greatly reduces water permeation and discoloration of materials, but applying AD-COAT does not alter the surface of the base material and the quality of finishing surface.
