Buried Concrete Walls
A liquid-applied waterproofing layer on prepared concrete before the specified drainage and protection layers are installed. Allow the coating to form its film before backfilling and protect it from puncture.
Polymer Modified Asphalt Coating
A water-based, cold-applied polymer modified asphalt coating for continuous waterproofing on concrete and complex details. Choose L grade when low-temperature flexibility leads the specification, or H grade when heat resistance is the priority. Compare the grades below and request a project quotation.

Product overview
Select the grade, then design the layer
Polymer modified asphalt coating is a water-based option for buyers who need a cold-applied bituminous waterproofing layer on prepared concrete and difficult details. It forms a continuous film after drying, making it useful where a roll membrane would need many cuts and overlaps. The coating is part of a designed waterproofing assembly, with the finished layer protected where required.
The grade decision has a practical trade-off. L grade combines 80 ± 2°C heat resistance with −15°C low-temperature flexibility; H grade increases the heat-resistance figure to 110 ± 2°C while its standard low-temperature figure is 0°C. Both grades share the listed solid-content, bond-strength, watertightness and elongation indices. A buyer should select the grade against the actual climate and assembly rather than choosing H solely because its heat number is higher.
For a useful project inquiry, send the grade, substrate, total area, design thickness, protection layer and destination port. We can then align the quotation and technical documents with the requested supply configuration.
Applications
Covered Roof and Deck Assemblies
Waterproofing beneath a designed protection or finish layer, subject to substrate and system compatibility. For permanent sun exposure, request an expressly specified exposed-grade system.
Junctions and Penetrations
Brush or roll coating around upstands, outlets and pipe entries with project-specified reinforcement where movement or stress is concentrated. These details need their own application sequence and thickness inspection.
Coating-and-Sheet Systems
A potential liquid layer within a compatible modified-bitumen sheet assembly. Confirm the sheet, primer, drying stage and adhesion requirements for the selected combination before procurement.
Key benefits
Water-Based, Cold-Applied Format
The coating is applied without heating the material or torching a sheet. The water-based format suits projects seeking a cold-applied bituminous layer, while normal ventilation, weather protection and safe-site practice still apply.
Grade-Specific Thermal Choice
L and H differ most clearly in heat resistance and low-temperature flexibility. Showing both sets of figures prevents a buyer from assuming that the grade with the higher heat figure also has the lower cold-flexibility figure.
Continuous Film on Prepared Surfaces
Once applied and dried as specified, the coating covers irregular profiles without sheet seams within the coated area. Performance still depends on the substrate, detailing, designed film thickness and protection of the finished layer.
Comparable Procurement Data
The table separates shared indices from grade-dependent values, including watertightness, bond strength and elongation. Buyers can shortlist the grade and request the matching quotation, technical data and project submittals.

Installation guide
View documents ↓Prepare the Substrate
Remove loose material, dust, oil and standing water. Repair unsound areas and define the substrate moisture and primer requirements for the selected project system before coating.
Treat Details First
Seal and reinforce corners, wall-floor junctions, outlets and penetrations as required by the design. Do not bridge active movement joints with coating alone.
Apply to the Designed Thickness
Stir the material and apply in controlled coats by a method suited to the selected grade and substrate. Let each coat dry sufficiently before the next, and verify consumption and film thickness against the project specification.
Protect the Finished Layer
Keep rain, standing water and traffic off the coating while it forms a film. Inspect coverage and details, then install the specified protection or finish layer before construction traffic or backfill.
Packaging & OEM
Confirm the Supply Configuration
Specify L or H grade, required pail size, quantity and destination port when requesting a quote. Packing, pallet layout and labeling can then be confirmed for the actual order.
Request Project Documents
Ask for the technical data, safety data and relevant test documentation for the selected grade and project requirement.

Frequently asked questions
Which grade should I request for my project?
Choose by the temperature requirement of the assembly: L is specified at −15°C low-temperature flexibility and 80 ± 2°C heat resistance; H at 0°C and 110 ± 2°C respectively. Share the climate, protected or exposed position, substrate and project specification so the offered grade can be checked against the design.
Is this coating the same as an SBS roll membrane?
No. This is a water-based, liquid-applied modified asphalt coating that dries to a film. A roll membrane is a factory-made sheet with its own reinforcement, thickness and joint details. The formats may be specified together in a compatible system, but their performance figures are not interchangeable.
Can it be left exposed on a roof?
Specify the complete roof system first. This page is intended for protected applications; permanent exposure requires an exposed-grade coating or approved finish with confirmed UV performance.
What information is needed for an accurate quotation?
Send the grade, substrate, project area, design film thickness, required packaging, destination port and any applicable project standard. These determine consumption, packing and the documents needed for approval.
Can it be used with a bitumen sheet membrane?
A coating-and-sheet assembly is possible when the chosen materials and installation sequence are compatible. Confirm drying, adhesion, primer and membrane requirements for the proposed system rather than treating all sheets as interchangeable.
