What are Thermoset Membranes?
All thermoset membranes possess the quality of recovery. Since thermoset membranes are rubber like, it will stretch, but return to its original shape when released. The amount the material elongates is reduced by the presence of reinforcement in the membrane.
TYPE OF THERMOSET MEMBRANE
EPDM – One of the most common single-ply membranes used on buildings today.
EPICHLOROHYDRENE (ECH)
NEOPRENE (CR)
HYPALON (CSPE) – Hypalon can have a variety of repair procedures. The repair process can be different from the other type of membranes mentioned.
GENERAL REPAIR
Surface Coating Deterioration – EPDM, Neoprene, ECH, Hypalon
- Thoughly clean the surface of the membrane of all debris, dirt and unbonded coating using a pressure washer (keep the pressure around 700psi to avoid damaging the membrane).
- Allow the membrane to dry.
- Inspect for loose coating. If any additional loose coating is found, repeat steps 1-2.
- Reapply new coating that is compatible with the membrane material and existing coating.
