More than a product for a wet surface.
The practical value of the ONE family is its ability to work across challenging moisture and temperature conditions. The technical value comes from pairing that capability with the right grade, preparation, local repairs, reinforcement and detail components.
ONE®
The principal coloured liquid-applied membrane for compatible roofs, balconies, terraces and other substrates where damp or wet conditions affect product selection.
ONE® Vertical
The thixotropic vertical grade for upstands, walls, corrugated profiles and other geometry where the membrane must remain stable while maintaining continuity.
ONE® MAT
A dedicated reinforcement layer used where the current system design requires a reinforced build-up. Reinforcement strategy must follow the substrate and technical documentation.
Bands, pads and joints
Corners, penetrations and movement interfaces require dedicated detailing. The field membrane should not be expected to correct unsupported gaps or unprepared movement joints.
Assess, repair, detail, then waterproof.
The exact approved build-up changes with the substrate and project, but the control sequence remains consistent.
- 01Assess the substrate
Confirm strength, moisture condition, contamination, falls, existing coatings and the cause of any failure.
- 02Repair and regularise
Remove unsound material and complete compatible local repairs before the membrane is expected to bridge the surface.
- 03Resolve details and movement
Form corners, outlets, penetrations and joints with the correct bands, pads, sealants or movement detail.
- 04Apply the approved membrane build-up
Use ONE®, ONE® Vertical and ONE® MAT only in the combination, coverage and sequence required for the assessed substrate.
- 05Verify continuity
Check weather conditions, coverage, reinforcement embedment, terminations and the completed surface before handover.
Four questions before ONE is selected.
Residual construction moisture, rain exposure, trapped water and active ingress are not the same condition.
A moisture-tolerant membrane still needs a stable surface free from loose material and bond-breaking contamination.
Cracks, board joints, wall junctions and penetrations need an intentional reinforcement or joint strategy.
Roof exposure, pedestrian use, vehicle traffic and vertical protection lead to different products and build-ups.
Guidance here. Controlled documents there.
This page explains practical selection and system logic. Current technical data sheets, certifications and manufacturer requirements remain controlled by the system manufacturer.
This is practical system guidance, not a project specification. Product suitability, preparation, reinforcement, consumption, weather limits and curing must be verified against the current manufacturer technical data sheet and the approved project build-up.
