PS-PUA-03 / Engineered System
PolyShield Metal Roof
Elastic protection for metal roofs and guttersCorrosion, laps and waterproofing treated as one integrated renovation challenge.
What this system was developed for
A clear project role, not a universal coating.
Metal industrial halls
Gutters and valley gutters
Overlapping and fastenings
Large airless suitable roof areas
Steel
Galvanized metal
Existing compatible coating after test
Combination of corrosion control and waterproofing
Suitable for complex profiling
Airless potential on large surfaces
Reflective variant possible
When is this route promising?
For a metal commercial roof, a polyurea system must not only bridge leakage, but also address corrosion levels, existing coating, deformation, fastenings and condensation risk. Pretreatment and primer determine reliability.
Complete system construction
Each layer has one controllable function.
The structure shown is a selection frame. Primer, layer thickness, consumption and details are only finalized after inspection, test surface and document check.

Have a project assessed ↗Frequently asked technical questions
Short answer, clear line of evidence.
Can polyurea stop rust?+
A membrane does not replace corrosion testing or metal repair. Loose corrosion, salts, weakened parts and existing coatings must first be treated appropriately.
Can a metal roof be sprayed airless?+
This is possible in suitable large zones, provided product documentation, wind, overspray, air inlets, environment and shielding allow this.
Does coating dissolve condensation?+
Not automatically. Condensation is caused by building physical conditions and requires a separate analysis

AttachmentWhy a primer is not an afterthought
The primer function depends on the substrate, porosity, moisture and the chosen membrane technology.

Application methodCold applied or hot spray?
Equipment, response time, project environment and geometry determine which polyurea route is appropriate.

Layer thicknessHow consumption becomes controllable
Optical coverage is not proof of layer thickness; material quantity is linked to work area and surface.
