One of the recommended methods for roof waterproofing is the use of waterproofing membrane, and the other is the combination of waterproof coating and mortar waterproofing agent, but the latter is the most common one. Because the roof will be eroded by the sun and rain for a long time, the simple use of mortar waterproofing agent is not flexible, and cracks may occur in the long run. Therefore, it is necessary to brush a flexible K 1 1 waterproof slurry first, and then make a protective layer of mortar waterproof agent, so as to meet the waterproof requirements. Roofing waterproof construction steps base surface is clean, moisture content is not more than 9%, smooth and dense, and each node is neat and complete, which meets the requirements. Second, the first waterproof layer (1), laying flexible waterproof layer, choose coating or coil. Its construction conditions require that the moisture content of the base surface should not be greater than 9%, so it is suitable for construction in the case of hot weather and sunny days in summer. Water storage experiments should be done after completion. (2) Take "one cloth and two coats" as an example: brush the paint once after cleaning the base course, lay a layer of glass fiber cloth matrix reinforcing material after drying to form a film, brush the paint once to fix the surface after flattening, and carry out the next paint construction after drying. The total thickness of waterproof coating should be more than 3 mm. (3), such as waterproof coiled material construction, clean up the base, brush the adhesive on the reverse side of the coiled material and the base, paste and roll according to the played baseline from far and near, and finally check the seam. Three, the second waterproof layer laying rigid waterproof layer, should be carried out within two days after the completion of the first flexible waterproof layer construction, mainly based on advanced fatty acid mortar waterproofing agent, cement, sand, fine stone aggregate, fiber, the thickness of the waterproof layer should be 20-30 mm..( 1), according to the specification requirements, install battens, and the frame setting is 4000mm× 4000mm. Then sprinkle water to make the base surface wet, but there can be no water. (2), according to the order from far and near, first high and then low, the prepared mortar or fine stone concrete will be constructed one by one, and the same frame will be completed at one time, and then leveled and compacted. (3), after the initial setting, take out the frame bar, calendering and finishing frame joints. (4), using flexible sealing material to fill the frame joints, and sealing the surface. Pay attention to sprinkler maintenance after the construction is completed. (5) If there is planting soil on the roof, it should be covered with planting soil in the shortest time. Fourth, the roof should be made of cement and then painted with waterproof paint. Choose a sunny day, the ground level is dry, and the ground level should be cleaned up without too much ash. Spread fiber cloth, fiber net and the like on the roof (of course, the better the material, the better), and then brush waterproof coating on it (there are many on the market, and some professional waterproof companies make their own waterproof coatings). In this way, the cloth "sticks" to the roof, forming a film on the roof. This film is waterproof. When the waterproof coating is dry, apply another layer. If there is a parapet on the roof, the root of the parapet should also be waterproof, just 30 cm high and rolled up. After waterproofing, wait for the waterproof paint to dry, and then stick bricks on it. Waterproof membrane, pay attention to the overlap, and invert the high point.

If it's the top floor, find a property and ask them to lay a layer of linoleum or asphalt on the roof. If someone lives upstairs, it depends on the specific situation, whether there is a gap in the cement between floors or left along the water pipe, and whether the water pipe between floors is broken. If it is the first type, put a layer of waterproof paint on the upstairs floor and your roof. If it is along the water pipe, it is good to spread waterproof paint near the water pipe. If it's caused by a broken water pipe. On a layer of mortar. After curing for 3-5 days, brush 9 1 1 polyurethane for tar-free waterproofing, spread a layer of fiber mesh and brush it again. After the waterproof is dry, apply a layer of protective mortar. What is the best way to waterproof the roof? When doing roof waterproof construction, we must take corresponding measures in combination with the actual situation to ensure the effect of waterproof construction. The role of roof waterproofing works will gradually lose in the long-term sun and rain, so some roof waterproofing works need to be done every few years to ensure that the roof waterproofing effect can be maintained.
