    Qin Shiou thought at first who was coming, but there was no warning at sea and no visitors on land. Later, when he saw tigers and leopards barking at their work clothes, he realized that the little guy also wanted to change into a suit.

    He explained a few words that this was for work. The tiger and the leopard bit one of his trouser legs, and he had to put on the body armor no matter what.

    Qin Shiou was so angry that bulletproof vests were heavy and not very ventilated. He didn¡¯t understand why the two little guys liked wearing them so much. He was not a stinky person. Who did the two little guys learn to be so stinky?

    He had no choice but to take out the dog bulletproof vests and put them on.

    After putting them on, 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 so amused that they took out their mobile phones to take photos with tigers and leopards. LaLaWangs also cooperated and they were very fond of the camera.

    Qin Shiou waved his hand, indicating that it was time to start work.

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

    Due to wind and rain, the originally milky white tiles have turned into a 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 the vicissitudes of the times. George said with emotion: "This house is at least half a century old. My father's cabin in the country is built in this style. Time flies so fast."

    The whole house is made of wood, and the wood in some places has rotted. Qin Shiou needs to replace it, or use a wood chip gun to fill it with sawdust. Finally, it has to be sealed with glue and painted with a layer of paint, which is very complicated.

    For this kind of old house, it costs a lot of money to repair it. The key is that it is a waste of time. For rich people, it is better to build a new one.

    Qin Shiou is used to living here and feels there is no need to change houses.  Moreover, only the corners of this villa need to be repaired. Overall, it is still very good. For example, the solid wood stairs in the house are very strong. After decades of use, there is no creaking sound when stepping on them. They are as stable as  rock.

    ? Canadian residences, especially country houses, are mainly made of wood. Unlike the domestic use of concrete and bricks, there is plenty of local wood, and the cost of building houses with wood is also low.

    For example, in Farewell Town, all the trees on the island belong to the government, but if someone wants to build a house, they can just apply and buy the wood on a piece of land at a very low price.

    Even if a new house is built, it still needs maintenance because it is still made of wood, and the maintenance cost is not low. About 2% of the money has to be spent on maintenance every year.

    The tasks that the teenagers have to do are only the simplest and non-dangerous ones, such as cleaning floors, wiping door and window glass, weeding, etc. The main work depends on Qin Shiou and the fishermen.

    Shaq introduced to Qin Shiou: "The most important thing to repair a house is the roof. Farewell Island is rainy and snowy, and strong winds often land, so the damage to the roof is the greatest. Later we will go up to see the aging of the roof. It has been there in the past two years.  The snowstorm probably caused damage.¡±

    After setting up the ladder, several people tied safety belts on their bodies and climbed up to the roof of the villa.

    In the first year after arriving, several warehouses in Daqin Fishery collapsed due to wind and snow. Shaq and Sea Monster helped repair them. The villas were okay, with more sophisticated materials and professional anti-corrosion.  More resistant to rain and snow.

    When I went up to the roof, I saw that the roof of the villa was made of layers of wooden boards. Some of them had been broken for several layers. Although some seemed to be intact, they would break into pieces when you touch them. They were already aged and disfigured.  .

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

    And if the roof is not well insulated, the air conditioner in the house will be turned on in vain in winter and the temperature will not be raised. Even if the air conditioner is turned on 24 hours a day, it will be useless.

    In Canada, the roofs of wooden houses need to be repaired about once every five years. This kind of repair is a major repair, and many things need to be replaced. Canada is a sparsely populated country. Except for the city center, most people live in small villas. It is basically necessary to replace them once.  It only costs 4,000 to 5,000 Canadian dollars, and the average person¡¯s monthly salary is gone.

    In addition, the roof must be replaced every 25 years, which is more expensive and can cost tens of thousands of Canadian dollars.

    Qin Shiou discussed with Shaq and others: "Should we do a major overhaul and replace everything with modern and universal glazed tiles?"Shaq shook his head and said: "Don't change it, boss. The glazed tiles look good, but are too heavy and will put a great burden on the walls of the house. Moreover, there is heavy wind and snow on the island, and the pressure of the glazed tiles will put a greater burden on the house, so use  Boards are just fine.¡±

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

    Iron Mountain is the most elegant and versatile tree species on the North American market. It is slightly lower in strength than yellow pine and is more suitable for anti-corrosion treatment. After pressure 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 coefficient of thermal expansion and contraction, and is resistant to sunburn.  It is common sense to know that almost all wood will turn black after being exposed to the sun for a long time. However, hemlock can still maintain the color when it was newly sawn after being exposed to the sun for many years, making it very beautiful when used as a roof.

    These hemlocks have been treated and have a layer of transparent paint on the surface, which is a mixture of anti-corrosion paint and reinforcing paint, which can not only enhance the anti-corrosion properties of the wood, but also increase its strength.

    ? This is also one of the advantages of hemlocks, they have excellent adhesive properties and can accept a variety of surface coatings.

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

    Nowadays, even if the roofs of country villas are made of wooden boards, they generally no longer use hemlock wood, but carbonized wood.

    Carbonized wood is made by homogeneous carbonization of wood using high temperatures. It does not require the use of 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 carbonized wood has a dark brown color, which seems to absorb sunlight and 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 properties, is simple to construct, easy to paint, has no special smell, and is anti-rot, anti-moth, anti-deformation and cracking, and is simply an excellent wood for external use.  choose.

    In addition, it also has the advantage of being light in weight. Because it is carbonized, it is completely degreased and does not leak grease. It is smaller in weight and puts less pressure on the walls and wooden beams of the house.  (Remember the website address: www.hlnovel.com
