When using a non‑curing spray machine, first ensure the substrate is thoroughly cleaned, then apply the primer evenly. Immediately roll out the waterproof membrane and perform venting and other necessary steps. Construction is prohibited on rainy days, and be sure to keep the thermal oil temperature below 230°C. Now, let’s take a look at how to properly operate the non‑curing spray machine!

　　Use Non-curing spray machine During construction, first thoroughly clean the substrate, then evenly apply a primer. Immediately use a roller to lay the waterproof membrane and perform air venting. Work is prohibited on rainy days, and ensure that the thermal oil temperature does not exceed 230°C. Now, let’s take a look at how to operate the non‑curing spray machine!

　　 I. Construction Process for Non-Curing Spraying Machines

　　1. Substrate Preparation for the Non-Curing Spraying Machine: The substrate surface shall be solid, smooth, dry, clean, and free of dust and contaminants. Corners shall be chamfered to a 50 mm × 50 mm angle or rounded with a radius of 50 mm.

　　2. Application of Primer: Apply the primer evenly to a qualified substrate. Thoroughly stir the primer before application, ensuring uniform thickness, no bare substrate exposure, and no buildup. Follow the principle of applying first to higher areas, then to lower ones, and finally to flat surfaces. Once the applied primer has dried, self-adhesive membrane can be laid.

　　3. When applying hot‑melt, non‑curing rubber‑asphalt waterproof coating: Prior to application, place the coating in a heating tank and heat it until it reaches a liquid state; proceed with application once the specified working temperature is attained. For hand‑scraper application, the heating temperature should be 120°C; for spray application, the spraying temperature should be 150°C.

　　4. Application of non‑cured rubber‑asphalt waterproof coating: Spread the non‑cured rubber‑asphalt waterproof coating from the heating tank onto the substrate to a thickness of approximately 1 mm. After applying the coating, within 3 minutes, unroll the adhesive‑backed waterproof membrane, gently scrape its surface to remove any air pockets, and ensure tight adhesion between the membrane and the non‑cured rubber‑asphalt waterproof coating.

　　5. Apply the waterproof membrane to the roller: After applying the non‑curing rubber‑asphalt waterproof coating to the substrate, immediately lay the waterproof membrane onto the roller. While on the roller, gently scrape the membrane’s surface to expel trapped air, ensuring a strong bond between the membrane and the liquid rubber. The overlap width of the adhesive‑backed waterproof membrane shall be 80 mm; in narrow areas, it must be no less than 70 mm, and the edges of the membrane must be tightly rolled with a pressure roller.

　　 II. Precautions for Non-Curing Spray Machines

　　1. Before commencing work, please inspect all machine components for loose screws to prevent potential hazards.

　　2. Before commencing work, please wear gloves and protective clothing to avoid contact with eyes and skin.

　　3. Before commencing work, please switch on the circuit breaker inside the control box. After powering up, verify that the phase sequence is correct; otherwise, the thermal circulation pump will fail to start.

　　4. During construction, it is strictly prohibited to pour water into the heat‑transfer tank, flue, or material bins to prevent scalding injuries caused by splashing hot water.

　　5. Construction personnel must keep clear of the flue to avoid burns. Work is prohibited on rainy days. When operating the equipment, the temperature of the heat-transfer oil must not exceed 230°C.

　　6. Prevent foreign objects from entering the material hopper to avoid interfering with machine operation. Do not commence coating until the material temperature has reached 180°C or met the specified coating standards.

　　7. Do not store the non‑curing spray machine for extended periods in a dry, well‑ventilated area. In the coating machine, the piston is rigidly connected to the paint plunger, and the piston’s cross‑sectional area is larger than that of the plunger; therefore, the incoming paint must be pressurized. The pressurized paint is then conveyed smoothly through a high‑pressure hose.

　　8. Do not commence coating until the material temperature has reached 180°C or met the coating specifications. Please do not store the equipment for extended periods in a dry, well-ventilated area.
