Roof Coating Systems Guide
System Selection Framework for Commercial Roof Coating Projects
Four coating systems serve different purposes in commercial roof refurbishment. TopSpray 35 for appearance-led refurbishment. SprayGrade for large-area waterproofing and asbestos encapsulation. ProFix for emergency repairs and detailing. Rocathaan Hotspray PA 260-FR for specialist pure polyurea waterproofing. System selection depends on substrate type, deterioration mechanism and project objectives.

Roof Coating Systems: Frequently Asked Questions
How Do I Select The Right Roof Coating System?
Roof coating system selection depends on substrate type, deterioration mechanism, project objectives and warranty requirements. TopSpray 35 is selected for appearance-led refurbishment with extended warranties. SprayGrade is selected for large-area waterproofing and asbestos encapsulation. ProFix is selected for localised repairs and emergency leak containment. Rocathaan Hotspray PA 260-FR is selected for specialist pure polyurea waterproofing. A site assessment determines the appropriate system for your specific building and project requirements.
What Substrates Can Be Coated?
Multiple substrate types can be coated depending on system selection. TopSpray 35 is suitable for pre-coated steel, steel with primer, polyurea/PU and epoxy substrates. SprayGrade is suitable for asbestos sheets, corrugated sheets, concrete, bitumen, PVC and composite panels. ProFix can be applied to wet surfaces, underwater conditions, metal, concrete and penetrations. Rocathaan Hotspray PA 260-FR is suitable for existing roofs, new construction, steel, concrete and polyurethane foam. A site assessment confirms substrate suitability for coating.
Which System Is Best For Cut Edge Corrosion?
Cut edge corrosion treatment depends on corrosion extent and project objectives. TopSpray 35 is specified for comprehensive cut edge corrosion treatment with main sheet over-coat where appearance and extended warranties are priorities. ProFix is specified for localised cut edge corrosion treatment where budget efficiency is the priority. A site assessment determines corrosion extent and appropriate system selection for your specific building.
Which System Is Best For Asbestos Roofs?
SprayGrade may be specified for asbestos roof encapsulation where a competent assessment confirms the roof is suitable. The water-based, VOC-free two-component spray-applied membrane contains the existing surface and restores waterproofing without removing the sheets. Warranty eligibility and specification depend on the project, and all work must follow CAR 2012, project RAMS and competent asbestos advice.
Which System Is Best For Waterproofing?
Waterproofing system selection depends on project requirements. SprayGrade is specified for large-area waterproofing where budget efficiency and broad substrate compatibility are priorities. Rocathaan Hotspray PA 260-FR is specified for specialist pure polyurea waterproofing where KIWA certification and extended warranty pathways are required. ProFix is specified for localised waterproofing repairs and difficult detailing. A site assessment determines the appropriate waterproofing system for your specific project.
Which System Is Best For Appearance?
TopSpray 35 is the premium system for appearance-led refurbishment. The high-build spray-applied coating from Prokol Protective Coatings offers superior UV resistance, colour retention and RAL colour matching capability. TopSpray 35 is specified where appearance, colour restoration and long-term warranty pathways (up to 25 years) are project priorities. SprayGrade, ProFix and Rocathaan are functional waterproofing systems without the appearance-led characteristics of TopSpray 35.
What Warranties Are Available?
Warranty availability depends on system specification. TopSpray 35 offers warranty pathways of up to 25 years subject to specification and manufacturer approval. SprayGrade carries a 15-year product warranty. ProFix provides up to 10-year protection for localised repairs. Rocathaan Hotspray PA 260-FR offers up to 35-year+ warranty pathways for specialist applications. Extended warranty pathways may require additional specification steps and manufacturer assessment.
Can Multiple Systems Be Combined?
Yes — multiple systems can be combined within a single project specification. ProFix is commonly used for localised repairs and detailing before primary system application. TopSpray 35 and SprayGrade can be specified on different elevations of the same building depending on substrate type and project objectives. A Forti Nova approved applicator will develop a hybrid specification optimising cost and performance for your specific project requirements.
How Is System Selection Determined?
System selection is determined through site assessment. The assessment examines: substrate type and condition, deterioration mechanisms, project objectives (appearance, waterproofing, budget efficiency), warranty requirements, operational constraints and budget considerations. Based on assessment findings, a Forti Nova approved applicator will recommend the appropriate system or hybrid specification for your specific building and project requirements.
What Happens If The Wrong System Is Selected?
Incorrect system selection can lead to premature coating failure, adhesion problems, warranty invalidation and recurring deterioration. This is why site assessment is essential before any system is proposed. Forti Nova's assessment process identifies substrate type, deterioration mechanisms and project objectives before recommending system selection. This reduces specification risk and ensures the appropriate system is specified for your specific building and project requirements.
Survey Before System Selection
System selection cannot be determined without a site survey. Substrate type, deterioration mechanism, and project objectives must be assessed on-site before recommending TopSpray 35, SprayGrade, ProFix or Rocathaan Hotspray. The survey provides the technical foundation for all system specification decisions.
Commercial Roof Survey
Professional roof condition assessment for commercial and industrial buildings. Identifies defects, plans maintenance, extends roof life.
Roof Condition Survey
Comprehensive roof inspection and assessment. Professional reporting, system recommendations, capital expenditure planning support.
Survey first, always: System selection should be grounded in site-specific survey findings. Submit an assessment request and a Forti Nova approved applicator will carry out a site survey before recommending coating systems.
