Factory Direct Supply
TY-SHIELD™ non-curing rubber asphalt waterproof coating — a single-component, hot-applied bitumen-based material designed to remain viscoelastic after application. It is used as a bonding and anti-water-channeling layer in composite systems with modified bitumen membranes. Formulation, application temperature, self-healing behavior, and test results depend on the selected grade; confirm the product TDS and project requirements before specification. Factory-direct supply with OEM drum labeling and custom formulation options subject to review.

PU cures into a rubber film. JS cures into a cement-polymer composite. Polymer modified asphalt cures by water evaporation. Every other waterproof coating on this page arrives as a liquid and turns into a solid.
This one arrives as a gel and stays a gel.
It is designed to remain viscoelastic after application, with the final behavior depending on formulation, application temperature, substrate, cover, and project conditions. Refer to the product-specific TDS for solid content and other test values.
What this means in practice: the coating is intended to accommodate movement through viscoelastic behavior rather than forming a conventional rigid film. Actual resistance to cracking, shrinkage, brittleness, and substrate movement depends on formulation, cover, exposure, installation, and system design.
JC/T 2428-2017 quantifies this behavior as stress relaxation: hold the material at a fixed deformation, and the force resisting it drops to ≤35% of the starting value. The coating stops fighting and yields to the movement. That’s not a weakness — it’s the reason it’s still waterproof forty years after rigid materials have failed.
The coating is generally used as a bonding and interface layer within a composite waterproofing system. Confirm the membrane combination, detailing, and installation method for the project.
The process is straightforward. Hot coating is applied to the substrate. An SBS or APP modified bitumen membrane goes down immediately while the coating is still hot, fusing into the coating surface as it cools. The result is a single composite assembly: membrane, coating, and concrete, chemically and mechanically integrated.
Why this matters: in a conventional sheet system, water that gets behind the membrane can travel sideways — channel — until it finds an entry point meters away from the damage. With the coating filling every void between concrete and membrane, there is nowhere for water to go. Any leak is trapped at its exact point of origin.
Applicable standards and performance parameters depend on the selected grade. Request the product-specific TDS and test documentation with your inquiry.

The coating is generally used as a bonding and interface layer rather than a walking surface. An SBS or APP modified bitumen membrane may be installed into the hot coating as part of a composite system. Final interface behavior and water-channeling performance depend on the complete system design and installation quality.
Tunnels, subways, deep foundations, and basement slabs may use non-curing coating as part of a composite waterproofing system. Suitability depends on hydrostatic pressure, substrate movement, chemical exposure, detailing, and the complete project specification.
For renovation projects, the coating may be considered over an existing bitumen surface after assessment and preparation. Compatibility, adhesion, substrate condition, and the need for removal or repair must be confirmed before application.
The coating may be used around selected joints and structural details where movement accommodation is required. Joint geometry, movement range, reinforcement, and detailing must follow the project waterproofing design.
A cured coating under tension behaves like a loaded spring — constantly pulling back on whatever it's bonded to. Over years, that pull causes creep failure at the bond line. Non-curing coating follows a different set of rules. Viscoelastic-viscoplastic models developed for bitumen-based materials explain the mechanism: when you stretch this material and hold it there, the internal molecular structure rearranges itself. The resisting force drops — not because the coating is degrading, but because it is adapting to the load. On a construction site, this translates to one thing: building movement doesn't get transferred into stress at the bond. The coating absorbs the movement internally. JC/T 2428-2017 calls this stress relaxation. A structural engineer specifying waterproofing for a tunnel that will settle over thirty years calls it peace of mind.
Cold-applied and hot-applied systems depend on substrate preparation and application control. When heated within the grade-specific range, this coating becomes more flowable and can conform to surface irregularities. Heating temperature, equipment, adhesion performance, and testing criteria must follow the product TDS and project quality plan.
A laboratory acid-resistance test uses clean sulfuric acid in deionized water at controlled room temperature. The groundwater against a real basement wall is a moving cocktail of dissolved minerals from the surrounding formation, chloride ions from decades of surface runoff, sulfates from decomposing organic matter, and variable pH from concrete leaching — all at concentrations that rise and fall with the seasons. JC/T 2428-2017 requires acid, alkali, and salt resistance not because specifiers want three check marks on a data sheet. It requires them because any single one of these exposures, sustained over years, can destroy a coating that was never designed to face it.
Water pressure testing evaluates both water resistance and interface stability. The applicable pressure, duration, substrate, and acceptance criteria depend on the product grade and project design. Confirm hydrostatic-pressure performance and adhesion documentation before using the coating in deep or high-water-table structures.

Scrape off loose material. Remove oil and grease — a pressure washer works, degreaser works, whatever cleans it. The substrate needs to be firm and free of anything that would stop the coating from gripping. Damp is fine. Standing water isn't — pump it out first. If the surface is wet enough that you can wipe water off with your hand, dry it before you start.
Transfer the coating from the drum into a heating tank. Heat to 120–200°C with continuous stirring. Don't stop stirring — local hotspots degrade the polymer. Once it's uniformly fluid, you're ready. Don't hold it above 200°C for more than thirty minutes. If you're working in winter and the substrate is cold, heat it toward the upper end of the range so it stays workable longer after application.
For basements, tunnels, and big flat surfaces, use a continuous-feed spray gun. One operator, one pass, 1.5–2.0mm dry film thickness. The speed means you can cover a foundation slab in a morning and have the membrane crew following behind you the same afternoon.
Switch to a heated trowel for penetrations, corners, and edges. Apply the coating to at least 1mm thickness at these points before the main spray pass. If the detail design calls for it, embed non-woven reinforcement fabric into the hot coating — press it down with a trowel, no wrinkles, no air pockets.
