Learn the step-by-step process of installing SBS modified bitumen ground in this comprehensive guide. Find discounted SBS bitumen waterproof membrane with good price and quality for your project.

There are two construction methods of SBS modified bitumen waterproofing membrane.

1) Hot-melt paving method

(1) The construction cost of the waterproof layer can be reduced by adopting the hot-melt paving method, which not only saves the amount of adhesive, but also avoids the hollowing of the waterproof layer;

(2) The base treatment is a cement mortar leveling layer, which is required to be solid, smooth, shiny, and free of drumming. The base layer must be dry. The moisture content is required to be below 9%;

(3) Apply SBS modified asphalt waterproof membrane cold base oil on the dry base layer. It is required to apply evenly once and dry for 6 hours (depending on the temperature, it is better not to stick to the feet);

(4) First put the coiled material in the right position, light the blowtorch (the distance between the blowtorch and the coiled material is about 0.3 m), use the blowtorch to heat the coiled material and the base layer, and roll it forward after the surface of the coiled material melts. Do not get involved in air and foreign matter during the process, and require compaction and flattening. Before the coil is cooled, use a trowel to seal the edge, and then use a blowtorch to seal the seam evenly and meticulously, paying special attention to the edge and complicated parts to prevent warping;

(5) The construction technology of the double-sided method is basically the same as that of the single-layer method. The second layer of paving and the first layer of coiled materials should be staggered by about 0.3 m according to the seam (generally, a single layer can be used for buildings);

(6) Safety protection: In hot melt construction, it is necessary to strengthen the storage of gasoline and the management and maintenance of blowtorches to prevent fires and industrial accidents.


2) Cold bonding method

(1) Base treatment and brushing base treatment agent are the same as hot melt paving method;

(2) Paint base adhesive: SBS adhesive, rubber asphalt adhesive, neoprene adhesive, choose one. It is required to apply and scrape evenly, and the dosage per square layer is 0.5-0.7 kg;

(3) Paving and sticking waterproof membrane process: first put the membrane in position and leave a 10 cm wide stubble, roll the front and roll the back. , no wrinkle, no drumming, the seam should be fully coated with adhesive, dry for 20 minutes and then press hard to make it stick firmly.

(4) Surface treatment: If sand protection is required after the coil is pasted, a layer of rubber asphalt paint can be applied, and sand or mica can be sprinkled. process.

Regarding the construction process of sbs modified asphalt waterproofing membrane, it is not difficult to know that it is different from the actual situation according to the above, and there are various methods for reference. Correspondingly, and according to consumer budget requirements and tool conditions, there are many personalized options that can be provided. For example, the hot-melt paving method is a widely used one. It is also important to understand its performance parameters and features and advantages in advance, so the above also includes the knowledge section on product popularization.

Are you looking to install SBS modified bitumen ground? Look no further! This comprehensive guide will walk you through the step-by-step process, ensuring a successful installation. Whether you're a contractor or a DIY enthusiast, understanding the proper installation techniques is crucial for long-lasting and durable results. Additionally, we'll provide information on where to find discounted SBS bitumen waterproof membrane of exceptional quality and affordable price. Let's dive into the details!

Before you begin the installation process, gather all the necessary materials. You will need SBS modified bitumen waterproof membrane rolls, a utility knife, a squeegee, a propane torch, a pressure roller, and a measuring tape. It's essential to choose high-quality SBS bitumen waterproof membrane to ensure optimal performance and longevity. Consider checking out our recommended sources for discounted SBS bitumen waterproof membrane with competitive pricing and excellent quality.

Next, prepare the ground surface. Ensure that it is clean, dry, and free of any debris or loose materials. Smooth out any rough patches or irregularities in the surface. Proper preparation of the ground is crucial to achieve a smooth and even installation of the SBS modified bitumen waterproof membrane.

Now, let's move on to the installation process. Unroll the SBS modified bitumen waterproof membrane carefully, starting from one end of the surface. Make sure it aligns perfectly with the ground, leaving no gaps or overlaps. Use a squeegee to press the membrane firmly onto the ground, removing any air bubbles or wrinkles.

Next, heat the surface of the membrane using a propane torch. This will activate the adhesive properties of the SBS modified bitumen, ensuring a strong bond with the ground. As you move along the membrane, use a pressure roller to firmly press it onto the ground, ensuring proper adhesion.

Continue this process until you have covered the entire surface with the SBS modified bitumen waterproof membrane. Trim any excess material using a utility knife to achieve a neat and professional finish.
