We will often see some stone with a grain similar to wood grain, which has good continuity and makes the overall space more coordinated and hierarchical. In this article, let’s talk about wood grainstone.
Wood grainstone is a kind of precious stone. It is a rock formed by calcium carbonate precipitation for many years. Due to the changes of various conditions in the precipitation cycle, it forms a texture similar to wood. There are many kinds of marble in the wood grain series and many colors. It can be used as floor, stone line, fancy thread, veneer panel, veneer panel, skirting line, stair steps, and special-shaped stones. It is a rare class of stone.
Part01 classification of wood grainstone
According to different stone materials, it can be divided into marble wood grainstone and sandstone wood grain stone;
According to different colors, it can be divided into purple wood grain stone, mahogany grainstone, and yellow wood grain stone;
According to different wood grain, it can be divided into the fine wood grain, large wood grain, straight wood grain, natural wood grain, etc;
According to the naming of the origin, the known wood grain stone can be divided into Guizhou wood grain stone, French wood grain stone, Italian wood grain stone, etc.

● Characteristics of wood grainstone
① Wood grainstone is a kind of limestone, mainly composed of calcium carbonate (CaCO3).
② Although wood grain stone also has similar textures and patterns to marble, they are essentially different. One of the important characteristics is that the formation process of limestone has not experienced metamorphism and crystallization like marble.
③ Physical properties limestone is fragile, and its flexural bulk density, bending, and compressive strength are not high.
④ High water absorption, calcium carbonate composition, and powder structure make the water absorption of limestone generally very high. We all have a similar experience on the wood grain stone without protection, so the wood grain stone must be protected on six sides.
● Common problems of wood grainstone
1. Not easy to polish.
2. Easy to change color. After using wood grain stone, the color will change from light to dark, from dark to yellow, and other similar phenomena.
3.The joint of wood grain stone is prone to pollution, discoloration, and other problems.
4. Easy to return to alkali.
5. Easy to pollute.
● Pathological analysis of wood grainstone
The wood grain stone mentioned above is not easy to polish and pollute. The culprit is the ultra-high water absorption of wood grainstone.
1. Reasons for difficult polishing
Woodgrain stone polishing due to high water absorption. A considerable part of crystallizer, powder and other materials quickly penetrate the stone and cannot produce crystallization. And affect the final lighting effect.
2. Causes of discoloration
Due to the high water absorption, it is easy to absorb water during use and maintenance. With time, there are various unpredictable changes in color. On the contrary, the color change of marble and granite with low water absorption is much lighter than that of wood grainstone.
3. Reasons for easy discoloration and blackening of cracks
Because there are tiny pores in the wood grain stone, its adsorption rate is relatively strong. Dolomite glue, glue oil, and pigment in joint sealant are also easily absorbed by wood grain stone, leaving traces in the gap.
4. Reasons for easy alkali return
Wood grainstone is easy to absorb water and reacts with the components in the bottom cement to produce an alkali back phenomenon.
5. Causes of easy pollution
Woodgrain stone has a relatively loose structure, high water absorption, and a strong ability to absorb pollution. In daily use, it is easy to produce pollution under the joint action of foot dust, sewage, fruit juice, coffee, milk, tea, and other substances. Woodgrain stone protection must be done well
● Woodgrain stone lesion solution
Understanding the key reason for “high water absorption” and doing a good job of wood grain stone will have a scientific basis. If you want to do a good job of wood grain stone, you must do a good job of protection, make the best, and achieve a very high standard. Of course, the cost of wood grain stone protection is indeed higher. The details are as follows:
1. Brush repair type
When the wood grain stone plate has been brushed for protection in the factory, but the effect is poor and can not effectively reduce the water absorption of the stone, it should be brushed again.
① Selection of a protective agent
When the protective agent is applied, generally, the water-based protective agent cannot penetrate through the original protective agent. Therefore, penetration type protective agents, such as VD penetration type stone care protective agents, shall be used during supplementary brushing.
② Brushing standard
Sufficient, even, and healthy for more than 24 hours.
③ Precautions
There is also a standard for sufficient brushing. During brushing, if the front brush is applied, the back will immediately penetrate the wood grainstone, which proves that the protection amount is not in place, continue to brush.
It is not until the wood grain stone on the ground is brushed, and a layer of protective agent on the surface will not dry immediately that it is proved that the protective agent is brushed insufficient amount. The surface of the wall is always wet after applying a sufficient amount of wood grain protective agent.
2. Painting without protection
If the wood grain stone plate is not protected when leaving the factory, perfect protection treatment shall be carried out.
① Selection of a protective agent
For unprotected wood grain stone, first use a water-based protective agent, such as VD composite silane protective agent, and brush it evenly with 1:13 water. After 24 hours, apply sufficient and uniform secondary brushing with a penetrating protective agent, such as VD penetrating protective agent, and then place it for more than 24 hours.
② Brushing standard
Sufficient, even, and healthy for more than 24 hours.
③ Precautions
Through such meticulous and perfect protective treatment, the water absorption of wood grain stone can be reduced by more than 90%.
The grain of wood grain stone is novel and fashionable. Whether it is floor or wall, they can be integrated into the design and complement each other. In the design space, the lightness, tone, purity, and texture of the wood grain stone color can give people a clean, neat, beautiful, and generous impression. Well, that’s all for this article.
