Factory Direct Supply
TY-SHIELD™ polymer modified asphalt waterproof coating — a single-component, water-based SBS bitumen emulsion that cures by water evaporation into a seamless elastic membrane. Think of it as the same SBS chemistry found in your torch-applied waterproofing membrane — but delivered in liquid form, in a pail, applied with a brush or roller. No cutting. No torching. No seam welding. Where a roll membrane struggles with complex geometry, the liquid simply flows. Where seams create leak paths, a continuous film eliminates them. Available in L grade (standard, -15°C flex) and H grade (high-performance, 110°C heat resistance). Compliant with JC/T 408-2005. Factory-direct supply with OEM pail branding and custom formulations.
Typical Applications
Cold-applied by brush, roller, or spray — no heating, no torching

You already know SBS modified bitumen as a waterproofing material. It’s the polymer that makes your roll membrane elastic — that stretches when the building moves, that stays flexible at sub-zero temperatures, that resists the thermal cycling from sun-up to sun-down on an exposed flat roof.
This coating is the same SBS chemistry — delivered differently. Instead of being coated onto a polyester mat and rolled up at the factory, it’s emulsified in water and sealed in a steel pail. You open the pail, stir it, and brush it on. It cures by water evaporation into a continuous elastic film with no seams.
The practical advantage of this format is geometry. A 1-meter-wide roll membrane handles rectangular areas well. It handles corners, penetrations, drains, and parapets with a knife, a torch, and a lot of patience. The liquid version doesn’t fight the shape — it flows into it. For flat roof refurbishment where the existing bitumen surface stays in place, for retaining wall damp-proofing where speed matters more than precision, for detail work that would be 90% cutting and 10% waterproofing with a roll — the pail is the right tool.
Two performance grades cover the climate range. L grade holds -15°C without cracking — suited for northern and high-altitude projects. H grade takes 110°C without flowing — suited for exposed roofs in hot regions. The trade-off is real: H grade sacrifices some low-temperature flexibility for heat resistance. Pick the grade that matches your climate, not the higher number.
The coating is manufactured to JC/T 408-2005. For international specification, equivalent ASTM test methods — D2939 for solids, D5147 for heat and cold performance, E96 for vapor transmission — are documented in the TDS. Your specifier can cross-reference without translation.

The coating bonds to old bitumen felt, aged asphalt, and weathered roll membranes. This means a failing flat roof doesn't need to be stripped down to the deck before waterproofing. Clean the surface, patch the obvious damage, brush the coating on. No open flame on a roof where insulation or timber might be underneath. No hot-work permit. No insurance rider for torch work.
Damp-proofing foundation walls and retaining structures is a volume job — large flat areas where speed matters. Roller application covers 1–2 m² per liter per coat. A 20kg pail covers a 15–20 m² section. The coating cures in place, the backfill goes on, and the wall stays dry. No seams for groundwater to find.
Gutters. Downpipe outlets. Parapet upstands. Expansion joints. The places where cutting sheet membrane stops being installation and starts being origami. The liquid flows into these shapes. It doesn't care about the geometry. Two coats brushed in alternating directions, and every corner is covered.
Used between the structural slab and the screed as a continuous vapor-proof membrane. Applied to walls as a tanking layer before plastering. These aren't exposed applications — the coating is buried in the building assembly — but it does its job invisibly for the life of the structure.
Most polymer coatings need a clean, dust-free, oil-free surface — preferably with a bonding primer. This coating is bitumen-based. It bonds chemically to existing bitumen surfaces — old felt, aged roll membrane, previous asphalt coatings. You can overcoat a failing bitumen roof without mechanical stripping. This is not a universal property of waterproof coatings. It's a property of this specific material chemistry.
The liquid carrier is water, not solvent. A warehouse full of pails doesn't need explosion-proof electricals. Application in a confined basement doesn't require forced-air ventilation or occupant evacuation. ASTM D3960 testing confirms VOC levels under 50 g/L — well within the most stringent international green-building thresholds. This isn't a marketing claim. It's a documented formulation parameter.
At rest, the coating has a thick, paste-like consistency. When brushed, it thins and spreads. On a vertical wall, it holds its position without sagging or dripping. On a horizontal slab, it self-levels into a smooth, even film. This dual behavior comes from the formulation, not from on-site water adjustment or additives. Application temperature window: 5°C to 55°C — wider than many water-based coatings.
The Chinese national standard is JC/T 408-2005. For international specification, equivalent test methods are documented: ASTM D2939 for solid content and film integrity, ASTM D5147 for heat resistance and low-temperature flexibility, ASTM E96 for water vapor transmission. Your project specifier can validate the data against familiar test frameworks without interpreting an unfamiliar standard.

Sweep off loose dust. Scrape off anything flaking. Rinse off oil and grease — solvent wipe works, degreaser works, whichever you have on site. The substrate doesn't need to be sandblasted. It needs to be firm, clean, and not actively shedding material. Slightly damp is fine — standing water is not. Drain it first.
Pour some coating into a separate container. Add about 20% clean water. Stir. That's your primer. Brush or roll it onto the substrate — it should soak in, not puddle. If the surface is very dry or porous, give it two coats of primer. Wait until it's dry to the touch before the main coat. If more than 24 hours pass before you continue, re-prime the area.
Stir the pail thoroughly before use — settlement during storage is normal. Apply each coat at roughly 1–2 m² per liter. For large horizontal areas, a long-handled roller is fastest. For vertical surfaces, a medium-nap roller works — the coating's body prevents sagging. For details and edges, a brush. If you're spraying, use an airless unit with a tip size matched to the coating viscosity.
The first coat goes in one direction. Once it's dry to the touch — typically 2–4 hours, longer in cold or damp weather — apply the second coat at right angles to the first. The cross-direction pattern ensures any pinholes or thin spots from the first pass get covered by the second. Two coats are standard for waterproofing. Three if the substrate is rough and absorbs more material.
