L & R Weep Screed Highlights

L & R Weep ScreedTM is the only weep screed on the market that actually weeps.   The literature for most weep screeds actually states that the holes at the bottom are actually for the attachment of mortar, not weeping!  The L & R Weep ScreedTM is the only weep screed specifically designed to accommodate the full depth of the rainscreen drainage plane system and weep through the large slots along the bottom edge. Design for drainage with the first rainscreen-compatible weep screed from MTI.


  • It is the only metal termination on the market that is specifically designed to accommodate a rainscreen drainage plane material and weep
  • Forms the bottom edge of the scratch coat and the bottom edge of the thin-set mortar
  • Large 1” slots placed frequently along bottom edge provide favorable egress points for moisture to exit thin veneer wall systems
  • MTI’s Weep Screed Deflector, used in conjunction with L & R, acts as a bug screen as well as moves moisture away from foundation
