Roof waterproofing is a very important engineering project. Poor waterproof construction will directly affect the service life of the entire house. There are various types of roof waterproofing materials. For roof waterproofing, the key are waterproof membranes and waterproof coatings. Which one to choose?

Roofing waterproof material
1. Tile
The tiles covering the roof also have a waterproof effect. The tiles are mainly flat tiles and linoleum tiles, which are mainly used for rural self-built houses and urban villas.
2. Coiled waterproof material
The waterproof membrane material mainly includes waterproof membrane made of asphalt, waterproof membrane made of synthetic polymer material and waterproof membrane made of high polymer modified asphalt.
3. Waterproof material of coating film
Coating waterproof materials are the most commonly used roof waterproof materials on the market, mainly polymer concrete coatings, polymer modified asphalt concrete waterproof coatings.
4. Rigid waterproof material
Rigid waterproof materials mainly include shrinkable concrete waterproof layers, concrete waterproof layers made of general fine stones and concrete waterproof layers constructed with steel fiber materials.
For example, if you have a self-built house in the countryside, you must first use tiles, and then use waterproof paint for the waterproofing of the small balcony. Which material is better for roof waterproofing depends on the natural environment.

Construction steps for roof waterproofing
1. Clean up the base layer, before the construction, the dust and dirt on the surface of the base layer should be cleaned, and then use the hot-melt method to modify the asphalt waterproof coiled material. Make additional layers.
2. Lay the waterproof membrane, first of all, the thickness of the waterproof membrane should be in accordance with the regulations, cut the waterproof membrane to the corresponding size, use the flame spray gun to heat the junction between the base and the waterproof membrane, while the surface of the waterproof membrane Roll and roll the waterproof membrane forward when it melts. The waterproof coiled material connecting the flat surface and the vertical surface should be developed from bottom to top.
3. Hot-melt the edge, heat the overlap of the waterproof coiled material with a spray gun to make it adhere firmly, and then brush the first pass of waterproof coating. Before the waterproof construction, make sure that the ground is clean and dry, the waterproof coating should be fully coated to ensure that it is not neglected, it should be firmly combined with the base layer, without cracks and bubbles, etc. The thickness of the waterproof material must meet the requirements of the product
4. Carry out the second waterproof brushing after the first waterproof material is completely dried. If the second waterproof construction is carried out without drying the first waterproof paint, the waterproof effect will be greatly affected.
5. Lay a protective layer. After the waterproof work is done, lay a protective layer on the surface layer to prevent the waterproof layer from being damaged during the subsequent construction. The protective layer should be completely covered by the waterproof layer to ensure that there is no omission and it is combined with the base layer. There is no bubble and shedding phenomenon firmly.
6. Closed water test, the height of the water should not be less than 2cm during the closed water test, and then observe for more than 24 hours to see if there is any leakage, if it is not qualified.
