Fully trafficable once cured, Ultraflex has excellent adhesion to different substrates including plywood, bitumen, asphalt, metals, brick, concrete and wood. The product is also fully BBA certified in excess of 25 years and holds NHBC and Green roof approval.
Frequently Asked Questions
What makes single-component polyurethane application simpler?
Ready-to-use formulation eliminates mixing errors and on-site waste associated with multi-component systems. Material applies directly from containers using standard solvent-resistant rollers without catalysts or accelerators. Moisture-reactive curing process adapts to ambient conditions enabling year-round application. Single-component chemistry simplifies contractor training and reduces application mistakes. This convenience accelerates project schedules while maintaining consistent quality standar
How does wet-on-wet matting installation achieve instant waterproofing?
Reinforcement matting embeds into first liquid coat then receives covering layer creating fully encapsulated composite membrane. Once matting becomes saturated within liquid membrane, roof achieves immediate rain resistance protecting substrate. This three-step process (liquid-matting-liquid) proceeds continuously without curing delays between applications. Seamless installation methodology eliminates vulnerable transition periods during multi-day projects. Rain occurring mid-application won't compromise completed encapsulated sections.
Which substrate types accept Ultraflex without primer preparation?
Bitumen membranes, asphalt surfaces, plywood, OSB, metals, brick, concrete, and timber accept direct application eliminating primer costs. Excellent adhesion chemistry bonds to diverse materials without intermediate bonding agents. EPDM and TPO surfaces require compatibility patch testing before full application. Fresh concrete demands 28-day curing period achieving stable moisture content. QBM supplies Ultraflex to contractors working across varied substrate conditions.
What coverage rates determine material quantities for projects?
Typical coverage achieves 8-10 square meters per 15kg drum depending on substrate porosity and condition. Application thickness requirements vary based on traffic exposure and performance specifications. Rough or porous substrates consume additional material compared to smooth surfaces. Reinforced systems using matting require sufficient liquid ensuring complete fiber encapsulation. Accurate quantity estimation prevents material shortages disrupting project continuity.
How does 25+ year BBA certification justify system selection?
British Board of Agrément independent testing validates extended service life expectations reducing whole-life costs. NHBC acceptance confirms suitability for new residential construction under warranty programs. ETA (European Technical Assessment) certification demonstrates compliance with harmonized European standards. Documented performance history supports specification confidence for long-term building protection. Insurance and warranty considerations favor certified systems with proven track records.
