METACRYLICS / 11 substrate-specific roof dossiers

Diagnose the roof. Then build the system.

Select the existing commercial roof, including EPDM, TPO, PVC, metal, BUR, modified bitumen, SPF, tile, or deck. Then inspect the preparation, energy efficient coating layers, checkpoints, and system documents.

Reinforced Acrylic Over EPDM

EPDM is a synthetic rubber commonly used for single-ply membranes. As it ages, EPDM erodes, shrinks, and develops seam failures. A substrate-specific rinse and reinforced acrylic assembly restore it to a watertight, reflective state.

System fit

Best for an aging but serviceable EPDM membrane where the field sheet can remain in place.

A seamless reflective surface that protects the EPDM from UV exposure and future weathering.
01

What usually fails

  • Shrunken sheets and stressed perimeters
  • Open laps or fatigued seam tape
  • Chalking that weakens coating adhesion
02

Field preparation

  • Map wet areas and repair the membrane first
  • Wash and condition with EPDM Rinse
  • Run an adhesion test before full application
03

Release checkpoints

  • Seams and patches are fully bonded
  • Drains and penetrations are three-coursed
  • No trapped moisture remains below the membrane
