Spray-Applied Quick-Setting Rubberized Asphalt Coating

Two-component rubber asphalt coating that breaks and forms a seamless elastic membrane in seconds as the emulsion meets the coagulant at the spray nozzle — high-speed spray application for large areas, outstanding crack-bridging, self-healing and adhesion to complex details, ideal for roofs, basements, tunnels and industrial projects.

Everything You Need to Know

Overview

It is a two-component spray-applied waterproofing system. Component A is a rubber-modified asphalt emulsion and Component B is a coagulant solution. The two components are delivered through separate hoses and meet at the spray nozzle, where the emulsion breaks and coagulates instantly — a seamless, high-elasticity rubber asphalt membrane forms on the surface within seconds.

✅ Instant film formation — the membrane forms in seconds at the nozzle; no sagging on vertical surfaces, no waiting between coats
✅ High-speed application — a spray crew can cover several thousand square meters per day
✅ Fully seamless — no laps, no joints and no weak points, even at pipe penetrations, corners and other complex details
✅ High elasticity — elongation ≥ 800% bridges structural movement and thermal cracking
✅ Self-healing — minor punctures and cuts seal themselves in the elastic rubber membrane
✅ Strong adhesion to concrete, mortar, metal and existing waterproofing layers
✅ CE & ISO certified — meet standard
✅ OEM/ODM available — custom label, specification, color and packaging

Applications

🏗 Roofing — Large flat and low-slope roofs for factories, warehouses and commercial buildings; ideal for roofing contractors and developers (with protective layer or top coating where exposed)
🏚 Basements & Underground — Basement external walls and slabs, foundations and underground parking structures
🚇 Tunnels & Infrastructure — Tunnels, culverts and municipal infrastructure projects
🏊 Pools & Water Tanks — Swimming pools, water tanks and reservoirs (with tile or protective finish)
🏭 Industrial Facilities — Plant roofs and floors where fast, large-area application minimizes downtime
🔧 Complex Details — Pipe penetrations, parapets, corners and irregular details that are difficult to seal with membranes

Why an instant-breaking two-component system:

Component A and Component B meet only at the spray nozzle — the emulsion breaks and coagulates into a membrane within seconds, so nothing can clog the hoses and vertical or overhead surfaces can be coated without sagging. Large areas are sprayed in a single continuous pass with no laps, and the surface can be walked and water-tested the same day, which shortens project schedules dramatically.

FAQ

Q: What is a spray quick-setting rubber asphalt waterproof coating?
A: It is a two-component spray-applied waterproofing system: a rubber-modified asphalt emulsion (Component A) and a coagulant solution (Component B) meet at the spray nozzle and the emulsion breaks instantly, forming a seamless, high-elasticity rubber asphalt membrane within seconds.

Q: How does the two-component system work?
A: The two components are pumped through separate hoses and mix only at the spray nozzle. On contact the emulsion breaks and coagulates into a membrane in seconds — no pre-mixing, no pot-life limits and no clogging of the equipment.

Q: How fast can it be applied?
A: A trained crew with spray equipment can cover several thousand square meters per day, which is why the system is used for large roofs and infrastructure projects with tight schedules.

Q: Where is it typically used?
A: Large flat roofs, basements and below-grade structures, tunnels and culverts, pools and water tanks, and complex details such as pipe penetrations and parapets.

Q: What equipment is required?
A: A two-component airless spray unit with dual-feed hoses and a mixing nozzle. Equipment specifications and supplier references are available on request.

Q: What are the key physical properties?
A: Tensile strength ≥ 1.0 MPa, elongation at break ≥ 800% and low-temperature flexibility down to -20°C; the membrane is also self-healing against minor punctures.

Q: How thick should the membrane be?
A: Typically 1.5–2.5mm depending on the project design; coverage is approximately 3 kg/m² (total, A + B) for a 2mm film.

Q: What is the minimum order quantity?
A: MOQ is 1000 KG.

Q: Can you customize the product?
A: Yes — custom packaging and private-label programs are available (OEM/ODM).

Q: What is the lead time?
A: 15–25 days after order confirmation.

Q: Do you provide samples?
A: Yes, samples available before bulk order.

Q: What certifications do you have?
A: CE, ISO 9001/14001/45001, CEC Green Label.
