One-Component Waterproofing Membrane
BEM is a one-component, cold-applied, non-slump waterproofing material that can be used for a variety of applications with building envelope products from W. R. MEADOWS. BEM cures to form a tough, flexible waterproofing membrane. BEM is a high quality moisture curing elastomeric waterproofing and sealing material.
BEM can be used in the forming of fillets and reinforcement at corners and as a flashing material.
- Bonds to asphalt and concrete.
- Solvent-free; will not shrink.
- Skins over in 50 minutes.
- Does not freeze.
- Cures to a tough, flexible membrane.
828 mL (28 Oz.) Cartridges (12 per Carton)
As a corner reinforcement and fillet, approximately 1.1 m/L (14 lineal ft./gal.). For a 76.2 mm (3″) flashing, approximately 1.4 m/L (17 lineal ft./gal.) As a fillet, approximately 10.9 m/L (135 lineal ft/gal.).
When stored indoors and in original, unopened containers at temperatures between 4° – 21° C (40° – 70° F), shelf life is one year from date of manufacture.

VOC Content: 42 g/L
Surface Preparation … All surfaces to be covered with BEM should be clean, free of all contaminants, dry, and frost-free.
Application Method … Trowel on BEM to a minimum thickness of 90 mils. BEM may be applied to both primed and unprimed asphalt and concrete surfaces. Apply in 76.2 mm (3″) or 101.6 mm (4″) wide strips of material over terminations. When used as a corner reinforcement, apply a minimum of 152.4 mm (6″) wide in each direction. When used as a fillet, the face should be a minimum of 19.1 mm (¾”). At drains and protrusions, BEM should overlap the AIR-SHIELD™, MEL-ROL®, and/or PRECON® membrane at a minimum of 50.8 mm (2″) and should extend 152.4 mm (6″) above the surface or to the top of the wearing course.
If applying fresh material over the cured membrane, the cured membrane should be lightly washed and wiped with alcohol. Allow for a few minutes to dry and trowel on the fresh material.
Drying Time … 50 minutes +/- 15 minutes. Discard material that begins to thicken and becomes difficult to apply. BEM will cure to form a tough, flexible membrane.
Cleanup … Tools can be cleaned with alcohol. Follow manufacturer’s precautions when using alcohol for cleanup. Cured material is best removed by mechanical means.
BEM is not to be used as a liner in a water-containing structure or as an exposed or wearing surface. BEM is a fluid-applied waterproofing membrane that is designed to be used as part of a complete waterproofing and drainage system. Do not use on surfaces that are later to be painted. Do not store in high temperatures. Refer to Safety Data Sheet for complete health and safety information.
