Qin Shiou initially thought that someone was coming, but there was no warning at sea and no visitors on land. Later, when he saw Hu Zi and Leopard dressing up and shouting at their work clothes, he realized that the little guy was also going to change into suits.

He explained a few words that this was something to be used for work. While Hu Zi and Leopard bit his trouser legs, he had to change into the bulletproof vest.

Qin Shiou was so angry that the bulletproof vest was heavy and not very breathable. He didn't understand why the two little guys liked to wear it so much. He was not a stinky person. Who did those two little guys learn so badly from?

There was no choice but to persuade him and he refused to listen. He had to take out his dog's bulletproof vest and change it to them.

After changing into it, the two little guys became happy, and then followed Qin Shiou slowly, as if showing off their clothes of similar colors.

George and Vivian were amused and took out their phones to take a photo with the tiger and leopard. Lala Wang also cooperated very well. They were full of affection for the camera.

Qin Shiou waved and signaled that it was time for everyone to start construction.

George instructed the teenagers to mix detergent with warm water and wipe the tiles on both sides of the exterior wall from the door.

When the wind and rain are blowing, the originally milky white tiles have turned into dull yellow or green because they are covered with moss. The moss can be wiped off, but the changing color cannot be wiped off.

The villa is full of vicissitudes of the times. George sighed: "This house is at least half a century old. My father's cottage in the countryside is like this. Time flies so quickly."

The whole house is built with wood, and the wood in some places has decayed. Qin Shiou needs to be replaced or used a wood chip gun to fill it. Finally, it has to be sealed with glue and painted with a layer of paint. It is very complicated.

For such an old house, it costs a lot of money to repair, and the key is to waste time. For rich people, it is better to build a new one.

Qin Shiou was used to living here. He felt that there was no need to change a house. Moreover, the villa was only repaired by the corners. Overall, it was very good. For example, the solid wood staircase in the house was very strong. It took decades to use it, but there was no creaking sound when it was stepped on it, and it was as stable as a rock.

Houses in Canada, especially country villas, mainly have wood texture, unlike those used in China. There is a lot of local wood, so the cost of using wood to build a house is also low.

For example, in the farewell town, the trees on the island belong to the government, but if someone wants to build a house, just apply and buy a piece of wood on the ground at a very low price.

In this way, even if a new house is built, it still needs maintenance because it is made of wood, and the maintenance cost is not low. You have to spend about 2% of the money to repair it every year.

The work the teenagers have to do is the simplest and dangerous one. Wiping the floor, doors, windows, and weeding is mainly due to Qin Shiou and the fishermen.

Shaq told Qin Shiou: "The most important thing in repairing a house is the roof. Say goodbye to the island is rainy and snowy. And there are often strong winds, so the damage to the roof is the greatest. We will go up and see the aging of the roof later. There were snow disasters in the past two years, which probably caused damage."

After building a ladder, several people tied seat belts on their bodies and then went to the roof of the villa.

In the first year of my arrival, several warehouses in Daqin Fishery collapsed due to wind and snow. It was Shaq and the sea monster who helped repair it. The villa was fine. The materials used were more exquisite and professional anti-corrosion. The resistance to rain and snow was stronger.

When I got up on the roof, I saw that the roof of the villa was made of layers of wooden boards. Some had broken several layers, and some looked complete, but when I reached out, I would turn into pieces and had become distorted.

There should be no problem with the roof of this kind of villa, otherwise it will easily cause more damage to the house. For example, once it leaks, it will obviously corrode the walls, because the walls of the villa are also wood, so it is not as simple as moldy or even rot.

If the roof is not insulated well, the air conditioner in the house will turn on in winter and the temperature will not be raised. Even if the air conditioner is turned on for twenty-four hours a day, it will be useless.

In Canada, the roof of wooden houses needs to be repaired every 5 years. This kind of repair is a major repair, and many things need to be replaced. Canada is rare. Except for the city center, most people live in small villas. It costs basically four or five thousand Canadian dollars to change once, and the monthly salary of ordinary people is gone.

In addition, the roof has to be replaced every 25 years, which is more expensive and cannot be obtained without a tens of thousands of Canadian dollars.

Qin Shiou discussed Shaq and others and said, "Would you like to have a major renovation and replace it with modern and universal glazed tiles?"

Shaq shook his head and said, "Don't change it. The glazed tiles look good, but they are too heavy and will cause a lot of burden on the walls of the house. Moreover, the wind and snow on the island are heavy, and the pressure of the glazed tiles will make the house more burden, so it's good to use wooden boards."

Mr. Qin was very particular about people. At that time, hemlock was used on the roof wood.

Tieshan is the most elegant and widely used tree species on the North American market. It is slightly lower than yellow pine in terms of strength and is more suitable for anti-corrosion treatment. After pressurized anti-corrosion treatment, it is both beautiful and strong, comparable to the natural and durable North American red cedar.

Hemlock is very suitable for roofing because it has great stability, has a small thermal expansion and contraction coefficient, and is resistant to sun tanning. It is common sense to know that almost all wood will turn black after long-term sun exposure, but hemlock can maintain the color of the newly sawed after sun exposure for many years, making the roof very beautiful.

These hemlock trees have been treated and have a layer of transparent paint on the outside, which is made of a mixture of anticorrosion paint and reinforcement paint. They can not only enhance the anticorrosion performance of the wood, but also increase its strength.

This is also one of the advantages of hemlock. They have excellent adhesive properties and can accept various surface coatings.

The roof has several layers. After Qin Shiou repaired it with hemlock, he added another layer of charcoal wood.

Nowadays, even if wooden boards are used in the roof of rural villas, hemlock is generally not used, but carbonized wood is used.

Carbonized wood is made by homogeneous carbonization of wood using high temperatures. It does not require chemical agents. Its ability comes from itself, so it has a more stable anti-corrosion and resistance to external forces.

Moreover, the surface of the wood after carbonization has a dark brown color, which seems to absorb sunlight, which is very beautiful.

Carbonized wood has low moisture content, is not easy to absorb water, is stable in material, does not deform, has good thermal insulation performance, is simple to construct, is easy to apply, has no special odor, and is anti-corrosion, insect worm-resistant, deformation and cracking. It is simply an excellent choice for external wood.

In addition, it has another advantage of being light weight, because it has been carbonized and completely degreased without spillage, has a smaller mass, and also has less pressure on the walls and wooden beams of the house. (To be continued.)
