SP Liquid Membrane® – Waterproofing Membrane
Resources
SP Liquid Membrane is a tough, one-part elastomeric hydrocarbon rubber compound coating that is loaded with a ceramic pigment for strength. Upon curing, SP Liquid Membrane provides a protective coating film of superior adhesion and flexibility, and is resistant to abrasion and impact. SP Liquid Membrane can be used as a primer, as a one-coating system or as a topcoat to seal Super Therm from ponding water. SP Liquid Membrane can be applied over pressure-washed substrate of TPO, EPDM, PVC, wood, concrete or metal.

Typical Uses
- As a protective coating on metal, concrete, wood, etc. to add water resistance and longevity.
- As a one-coat system on new or existing roofs, and other commercial/industrial surfaces with minimal surface preparation.
- As a moisture protective membrane to stop moisture penetration, contaminants, and mold and mildew.
- Top coat in a thin film over the HPC and HSC to protect them from weathering, water and to help guard from abuse during normal operations.
Application Methods
SP Liquid Membrane can be applied to concrete, EPDM, TPO, PVC, wood, metal or masonry substrates. The coating can be applied by spray, brush or roller. For specific instructions on surface preparation, mixing and application, please refer to the SP Coatings’s application instructions for SP Liquid Membrane (millage may vary due to surface profile), and what is required of the coating.
