1. What is the difference between oily and water-based waterproof materials?
The main difference between oil-based and water-based waterproof materials is that oil-based coatings are insoluble in water and can only be dissolved with chemical solvents to dilute. Therefore, chemical substances are volatilized, so they are relatively unenvironmental. Water-based paint can be diluted with water, so the volatile substance is water vapor, which is non-toxic and harmless. Its characteristics are relatively environmentally friendly. It can be constructed on a wet base surface. Oily waterproof materials have higher requirements on the base surface. Construction on the base surface.
2. How to do waterproofing of rural houses?
①. Foundation waterproof
When decorating, lay the foundation, try to wait for the moisture to completely evaporate, and then make a moisture-proof layer. During construction, you can use cement mortar to pave directly, or prepare some gravel for dry paving, and then fill the gaps with coarse sand. When filling the foundation, generally use the method of loose filling and soaking, but try to add dry ash Tamping and filling together can also reduce the water content of the foundation and have a certain effect on waterproofing.
②. Wall waterproof
On rainy days, rainwater will flow down the walls and easily accumulate in the corners of the walls. When the rain is heavy, it will overflow and flow into the house. Therefore, the waterproofing of the wall of the house cannot be ignored. If the wall is relatively thin, a layer of moisture-proof putty powder can be applied to the outer layer of the house, and then a layer of waterproof coating. The waterproof layer of the kitchen and bathroom space must also be done well, and the height and thickness of the wall waterproof layer must be adjusted according to actual use needs.
③. Roof waterproof
The drainage slope of the roof should be done well, and the slope should be adjusted appropriately according to the local rainfall. In areas with heavy rainfall, the drainage slope should be appropriately increased, and there should be no accumulation of water on the surface. The waterproof layer of the roof can be made by a combination of waterproof coiled material and waterproof coating, and the waterproof of special parts cannot be ignored.
