A flexible overlay route with new-deck capability.
FLEXITEC can create a seamless reinforced membrane across many common roof substrates. The key is not simply whether it can bond, but whether the existing roof is structurally and technically suitable to retain beneath an overlay.
Retain a suitable existing roof
Overlay can reduce strip-off and disruption, but only after moisture, adhesion, defects, movement and remaining serviceability have been assessed.
Create a complete new build-up
New-deck work still needs correct board installation, joints, edge details, penetrations and the full reinforced membrane sequence.
Resin, hardener, primer and CSM
The single-resin concept sits inside a complete system that includes the correct primer, powder hardener, reinforcement and detailing materials.
Standard or Platinum
FLEXITEC Platinum is the separate specified-project route, available by special order and governed by its own certification and installer requirements.
Reinforcement weight changes what the laminate can become.
FLEXITEC is not an unreinforced coating. The 225 g/m² system mat forms the reinforced roof membrane, while heavier 450 and 600 g/m² matting can be used in project-specific fabrication where a more substantial formed laminate is required.
225 g/m² chopped strand mat
The documented FLEXITEC reinforcement for the standard roof build-up, embedded into the first resin coat with the required overlaps and complete wet-out.
450 g/m² chopped strand mat
A heavier reinforcement option for more substantial shaped surfaces and custom fabrication. FLEXITEC resin demand must increase to fully wet and consolidate the additional glass weight.
600 g/m² chopped strand mat
Used where a thicker, more rigid formed laminate is required—for example bespoke weather-exposed counters, outdoor bar surfaces and other purpose-made constructions.
Res-Tec identifies 225 g/m² CSM as the standard FLEXITEC roof-system reinforcement and documents increased resin demand when heavier reinforcement is used. The 450/600 g/m² fabrication examples shown here are project-specific technical applications—not automatic substitutes for a controlled FLEXITEC roofing or guarantee build-up.
The roof assessment controls the resin schedule.
The same product family can be used on very different roofs, but the preparation and build-up must respond to the actual substrate.
- 01Survey the roof
Confirm deck condition, existing coverings, moisture, falls, drainage, movement and the cause of current defects.
- 02Prove compatibility
Identify the substrate precisely and confirm preparation, primer and any adhesion-test requirements.
- 03Prepare and form details
Complete repairs, trims, outlets, penetrations and reinforcement transitions before the main field area.
- 04Install the reinforced build-up
Control hardener, resin application, CSM embedment, laps, coverage and weather conditions.
- 05Inspect and document
Verify continuity, finish, terminations and the training or guarantee route required for the project.
Versatility still requires discipline.
A failing or moisture-loaded roof should not be retained simply because a coating can adhere to its surface.
Felt, asphalt, concrete, GRP, PVC and metal details can require different preparation and primer decisions.
Board joints, perimeter trims, changes in direction and penetrations must be incorporated into the reinforced build-up.
A custom counter, bar or formed object needs its own support, laminate thickness, reinforcement and finish—not only a roof-system coverage rate.
Fire classification, warranty, installer training and Platinum requirements should be established before pricing.
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 roof specification. Suitability, priming, coverage, catalyst or hardener control, reinforcement, weather limits, fire classification and guarantee requirements must follow the current Res-Tec documentation and approved project build-up.
