HBS200 Liquid Rubber Waterproofing Membrane
HBS200 is a single-component, cold-applied liquid-rubber waterproofing membrane for suitable roof areas, commercial gutters, penetrations, upstands and complex details. It is applied to compatible prepared substrates to form a seamless bonded membrane. Substrate condition, moisture, preparation, detailing and system compatibility must be confirmed before specification.

What it is
What is HBS200?
HBS200 is a single-component, cold-applied liquid-rubber waterproofing membrane used to form a seamless bonded layer over suitable prepared substrates.
What it is used for
What is HBS200 used for?
It may be used for suitable roof areas, commercial gutters, penetrations, upstands, joints and complex waterproofing details where a hand-applied liquid membrane is appropriate.
What it is not
What is HBS200 not designed to do?
It is not a structural repair system, traffic-bearing finish or automatic solution for saturated insulation, severe corrosion, unstable substrates or unresolved trapped moisture.
Potential substrates
Which substrates may be suitable for HBS200?
Potential substrates may include prepared concrete, masonry, metal, bituminous surfaces, timber and compatible existing coatings, subject to condition, preparation, adhesion and primer assessment.
Before specifying
What should be assessed before specifying HBS200?
Review substrate condition, moisture, drainage, movement, contamination, corrosion, existing coatings, penetrations and any evidence of structural or roof-build-up failure.
Who specifies and applies
Who should specify or apply HBS200?
Specification and application should be undertaken by competent project professionals and trained applicators working to the confirmed system requirements, with technical support where required.
Before use
What must be confirmed before HBS200 is used?
Confirm substrate compatibility, preparation, primer and reinforcement requirements, membrane build-up, weather conditions, detailing and the project-specific warranty pathway.
Related HBS200 Guidance
Precision Waterproofing for Complex Details
HBS200 is commonly considered where hand application and close control around details, gutters and penetrations are advantageous. Its single-component formulation eliminates mixing — applied by brush, roller or trowel. SprayGrade may be more appropriate for larger continuous areas where specialist spray application is justified.
Gutters & Details
Box gutters, parapet gutters, penetrations, edges, flashing and complex geometries where hand application allows close control around the detail.
Roofs and Maintenance Works
May be considered for suitable roof areas, maintenance works and phased refurbishment where hand application and access conditions are appropriate.
Access-Constrained Sites
No compressor, spray rig or electrical supply needed. Multiple operatives can work simultaneously with minimal site infrastructure.
Planned Maintenance and Localised Waterproofing
May be considered for suitable localised waterproofing and planned maintenance works where the substrate condition and complete system requirements have been assessed.
HBS200 or SprayGrade?
HBS200 — Hand Applied
Generally considered where hand application and close control around gutters, penetrations, upstands and complex details are advantageous. Single component, no specialist equipment required.
SprayGrade — Spray Applied
May be more appropriate for suitable larger continuous areas where specialist two-component spray application is justified. The two systems may be used within the same project.
Green Roof Detailing
Outlet collars and upstand junctions require careful detailing on green-roof waterproofing projects. HBS200 hand application can be used to form the membrane around drainage outlets and upstand junctions before build-up layers are installed. Green Roof Waterproofing Guide →
Is HBS200 suitable for your project?
Suitability depends on substrate condition, moisture, drainage, structural integrity and system compatibility. Visual inspection alone is insufficient. A pre-specification assessment is required before HBS200 can be correctly specified.
Assessment Required
Adhesion confirmation and substrate condition verification are required before HBS200 can be specified. Moisture must be assessed using an appropriate project method.
Potentially Suitable Substrates
Subject to condition, preparation, adhesion and primer assessment for the confirmed substrate type.
- Prepared concrete and masonry
- Metal roofing — gutters and details
- Bituminous surfaces in sound condition
- Compatible existing coatings (assessment required)
Not Suitable For
- Substrates with elevated moisture — assess and confirm threshold before specification
- Traffic-bearing surfaces
- Structurally unsound substrates
- Concealing saturated insulation or unresolved trapped moisture
- Larger continuous areas where spray application is more appropriate
Survey Requirements
- Moisture assessment using appropriate project method
- Probe testing at lap joints and edges
- Gutter fall measurement
- Upstand height verification
- Existing coating identification
Cannot Assess Visually
- Sub-surface moisture content
- Insulation saturation
- Deck condition beneath membrane
- Drainage capacity under load
- Chemical compatibility
Common Failure Indicators
Blistering within weeks
Elevated substrate moisture at application. Membrane separated from substrate due to vapour pressure.
Required Response
Strip blistered areas, dry substrate, retest and reapply.
Edge lifting at gutters
Inadequate primer or contaminated trim. Detailing rushed at terminations.
Required Response
Lift and reterminate edges. Confirm primer compatibility.
Thin coverage / pinholing
Insufficient coverage rate. Roller moved too quickly or warm conditions.
Required Response
Apply second coat to achieve specified DFT.
Specification Data
- Composition
- Single-component cold-applied liquid rubber membrane
- Application
- Brush, roller, trowel or airless spray
- Coverage
- 1.35kg/m² (airtight) or 2.7kg/m² (2mm waterproof) — confirm current TDS
- Cure
- Cure and overcoating times depend on membrane thickness, temperature, humidity, ventilation and substrate conditions. Confirm the current technical documentation before application.
Application Methods & Preparation
Brush, roller, trowel or airless spray. Multiple operatives can work simultaneously. Preparation depends on the substrate and its condition — surfaces must be assessed for adhesion, contamination, moisture, loose material, corrosion and existing coatings.
Note: Primer requirements must be confirmed during project assessment — they cannot be assumed in advance.
Weather Window
Application requires suitable dry weather and substrate conditions. Temperature, humidity, rainfall risk and the required protection period must be checked against the current technical documentation and project specification before work begins.
Warranty
Up to 25-Year Warranty on Qualifying Installations
Available on qualifying installations subject to the confirmed specification, preparation, application and warranty requirements. All of the following conditions apply.
Substrate moisture confirmed below threshold
Moisture must be tested immediately before application — not at survey stage weeks earlier. Assessment method must be appropriate to the substrate and project.
Trained approved applicator
Warranty pathway requires trained and approved contractor application.
Drainage adequacy confirmed
Gutters, falls and outlets must be adequate at time of application.
Detailing complete at all terminations
Gutters, penetrations, parapets and upstands detailed to the confirmed system specification.
Full system build-up maintained
Coverage rates and coat sequence must comply with the confirmed specification.
