Trem-Lar LRM - Tremco Roofing

1 Composition: Trem-Lar LRM is a single component, bitumenmodified moisture curing Uses: Trem-Lar LRM is designed as the waterproofingmembrane in a fully adhered protected membrane roof sys-tem for structural concrete to UL Roofing Materials and Systems Directory and/orFM Approvals for applicable system : Not intended for twin-slab, precast, or lightweight con-crete. Not for use as a traffic-bearing surface. Trem-Lar LRM requires acceptable protective surfacing suchas insulation with ballast, pavers, reflective and protectivecoatings, decorative surfaces, and protective covers. Concrete substrates must be free of all traces of bitumen prior to application of Trem-Lar : Horizontal areas: Squeegee ( Trem-Lar LRM-H)Vertical surfaces: Trowel ( Trem-Lar LRM-V)Equipment: Triangular notched squeegee to provide 60 mil( ) thick uniform : Available in 5 gallon ( ) : BlackStorage Life: Up to 12 months in unopened Standards: Meets or exceeds performance stan-dards of ASTM C LRMA One-Part Liquid Applied ElastomericRoofing MembraneRoofing & Weatherproofing Peace of Mind APPLICATION DATA:Conditions:Do not begin work during rainy or inclement weather or whensuch weather is imminent.

2 Rainfall will damage freshly appliedmaterial. Minimum recommended ambient air temperatureduring application: 40 F (4 C) and rising. Maximum allowedsurface temperature during application: 110 F (43 C).SURFACE PREPARATION:Concrete: Surface shall be dry, free of dust, oil, bitumen, cur-ing agents, form release agents, and other strength: 2,500 psi (17237 kPa), minimum. Theconcrete shall have a light steel trowel finish followed by anatural hairbroom to render a uniform granular texture. Newconcrete must cure 28 days minimum by either water, burlapor polyethylene cure , shotblast, or scarify existing concrete to assure thesubstrate is free of contamination and it has the proper surfacetexture to assure adhesion of the Trem-Lar the dry condition of the concrete with a rubber mattest. After taping the mat to the concrete for at least 24 hours,no liquid water droplets should be present on the undersideof the mat.

3 A valid test requires the concrete be warmed bythe sun during the :Clean metal surfaces of paint, oils, rust, and other /PREPARATORY WORK: Priming for Detail Course: Prime concrete detail areas with AlphaGuard C-Prime prior to application of Trem-Lar primer to fully dry prior to application of Trem-Lar penetrations:Provide a 1 x 1 (25 x 25mm) cant ofTrem-Lar LRM-V at parapet walls, columns, stacks, etc. InstallTrem-Lar LRM as a flashing to the specified height Extendflashing 6 (150mm) onto horizontal surface. Coating thick-ness: 60 mils ( ) (wet).Cracks of 1/16 ( ) or less:Pretreat shrinkage and non-moving structural cracks with Trem-Lar LRM applied at a thick-ness of 60 mils ( ) (wet) 3 (75mm) either side of of 1/16 ( ) or greater:Rout all cracks, movingstructural joints, and cold joints to 1/4 wide x 1/2 ( ) deep.

AlphaGuard C-Prime mustdry tack free (6 to 8 hours at 75 F (24 C) and 50% ) priorto application of Trem-Lar LRM.

5 Open time of AlphaGuard C-Prime is 72 hours after tack free cure. Trem-Lar LRM must beapplied within the open time. If open time is exceeded, sub-strate must first be mechanically abraded, then , prime concrete substrates with Tremlar LRM-Hthinned with toluene at a rate of 32 oz. toluene per gallon ofTrem-Lar LRM-H. Apply the thinned Trem-Lar LRM-H to theclean, dry surface at a coverage rate of 1 gal/SQ ( L/m2)Allow to dry 1 hour minimum and apply the specified cover-age of Trem-Lar LRM-H (must be applied the same day).Priming Trem-Lar LRM: If Trem-Lar LRM has been applied andcured in excess of 48 hours and an additional coat of Trem-LarLRM must be applied, prime the existing Trem-Lar LRM with Ge-oGard Primer. Apply Trem-Lar LRM while GeoGard Primer is : Apply Trem-Lar LRM-H directly to surface bysqueegee and cross-roll with a long nap roller to a uniform thick-ness.

6 Overlap previous day s work 6 (150mm) : 25 ft2/gal. ( ) per coat Test: Allow membrane to cure 36 hours minimum(75 F (24 C) @ 60% RH). Longer cure times will be requiredat lower temperatures and/or to placement of protective surfacing, water test appliedarea. Block drains and provide perimeter dams. Flood testarea with water for 48 hours. Do not exceed deck design loadrequirements during water Time: 24 hours at 75 F (24 C), 50% RH. Longer curetimes will result at lower temperatures and/or lower relative : Use Xylene or Toluene to remove Trem-Lar LRMfrom equipment before cure.
