BUILDER’S REFERENCE GUIDEBUILDING SUCCESSFULLY WITH DRYVIT RESIDENTIAL SYSTEMS.DUK504INTRODUCTION“Building Successfully with Dryvit EIFS” is a reference guide for builders, architects and otherprofessionals in the building industry, who deal with exterior insulation and finish systems.The information contained in this guide is intended to help building professionals ensure quality intheir EIFS installations. It can serve as a planning tool as well as a convenient reference sourceon essential components of a successful EIFS job.This guide is not intended to act as a substitute for Dryvit’s written specifications, applicationinstructions and details. Copies of those items are available by calling 01462 819555.Furthermore, since designs can vary greatly from project to project, we urge you to consult with adesign professional if you have concerns. Of course, you can always call Dryvit if you havetechnical questions relating to our products.Dryvit, the EIFS industry leader for more than 35 years, is pleased to bring you this guide as partof its ongoing commitment to quality and customer satisfaction.THE FOLLOWING IS A LIST OF MAJOR CONSIDERATIONS THAT WILL HELP ENSURE AQUALITY DRYVIT INSTALLATION.SUBSTRATES (INSPECTION/WALK-AROUND)Prior to starting a job, it is important that the EIFS contractor and the builder or representativewalk around the project to inspect and check the structure - making sure the walls and cornersare in plane and that the approved substrate and flashing is in good condition and properlyinstalled per local building code requirements.TERMINATIONS/FOUNDATIONProvide adequate clearance so that the Dryvit system can terminate a minimum of 200 mm (8”)above grade or as required by local code. This is important to allow for proper inspection by pestcontrol operators. All terminations require backwrapping unless Starter Track with weep holesis used. Backwrapping is defined as the continuation of the reinforced base coat across the faceand edge of the insulation board. The reinforcing mesh is continued onto the back side of theinsulation board a minimum of 64 mm (2 1/2”).EXPANSION JOINTSDissimilar Materials - When the system terminates against a dissimilar material, such as woodor concrete, the system shall be held back a minimum of 19 mm (3/4”) to allow for an expansionjoint and caulking.Floor Lines - In wood-framed construction, expansion joints are installed at each floor line toallow for framing shrinkage. Minimum of 19 mm (3/4”) is recommended.Other - Expansion joints should be included at areas where there is a change in substrate thatcould result in differential movement, at areas with significant movement, as expansion joints inthe substrate or building, or where the design professional requires. Minimum of 19 mm (3/4”)recommended.
PENETRATIONSTerminations at penetrations, such as windows, doors, light fixtures, hose bibs, dryer vents, wallreceptacles, etc. require backwrapping with reinforcing mesh and base coat. The insulationboard must be held back from the opening a minimum of 50 mm (1/2”) for proper sealantinstallation. A fillet bead of sealant is permitted around small penetrations such as hose bibs, etc.DECK FLASHINGDeck flashing should be installed to preclude water entry. In addition, flash the top edge of theDryvit system if it is cut to accommodate the header joist. Use good construction practices forflashing and sealant installation to ensure watertightness. Dryvit details are for generalinformation and guidance only.WINDOW FLASHINGNot all windows are created equal. It is important to use good quality code-compliant windows.Windows can be a significant contributor to water intrusion. Windows should be flashed andcaulked per window manufacturers’ recommendations to prevent water entry.ROOF INTERSECTING VERTICAL WALLA kickout or diverter flashing must be installed as the first piece of flashing at the end of the roofwhere it intersects the wall. All diverter joints must be soldered. Step flashing is to extend up thewall at least 150 mm (6”). The purpose of the flashing and diverter is to shed the water off theroof and keep it out of the vertical wall beneath.SOFFIT RETURNS/GABLE ENDSWhen frieze boards are to be installed, install the Dryvit system first; the frieze boards areinstalled over the Dryvit system and sealed as required.CRICKETS/CHIMNEY ENCLOSURECrickets are designed to deter the accumulation of snow and ice and deflect water around achimney. To finish masonry enclosures, it is recommended that a skim coat of base coat beapplied prior to application of finish. Use of insulation is not recommended due to possible heatbuildup. The wood-enclosed chimney chase can be finished with a full Dryvit system with EPSinsulation. Flashing should continue vertically 150 mm (6”) above the cricket. Flashing at the topof the enclosure must also be installed.SEALANTSExpansion joints and terminations at windows and other openings must be properly sealed. Useclosed-cell backer rod, sealant primer and Sealant. Consult the following manufacturers to verifythat they have tested their sealants for compatibility with EIFS:Pecora CorporationSealant: Dynatrol llPrimer: Type 75 or 150*Pecora CorporationSealant: 890 SiliconePrimer: P64*Tremco, Inc.Sealant: Spectrem 1, 3 and 4Primer: Primer 23*Sika CorporationSealant: Sikaflex 2CPrimer: Sikaflex 429*2
Dow CorningSealant: Dow Corning 790, 791**, 795**Primer: Dow Corning 1200* Prime CoatGESealant: Silpruf LM (scs 2700)Primer: SCP 3195P**Primer is for sealing Dryvit to Dryvit. For sealing Dryvit to other materials, consult with sealantmanufacturer.**Dow Corning 791 and 795 are intended to be used as perimeter seals and at penetrations.They are not intended to be used when sealing Dryvit to Dryvit.AVOIDING WATERWater intrusion into the exterior wall of any structure can lead to problems; therefore, attentionmust be paid to following proper details to minimize the risks.Traditional EIFS are barrier-wall systems designed to keep water out of the structure just likeother components that make up the exterior envelope. Dryvit offers an EIFS design thatincorporates a secondary weather barrier and a drainage plane. Incidental moisture that mayenter around the system reaching the secondary weather-resistant barrier harmlessly drains outof the wall. However, the critical step with all exterior siding in eliminating potential moistureproblems is planning for and executing properly the interfacing of the Dryvit system with all otheradjacent building components.It is important that the builder, EIFS contractor, roofer and framer together review all constructiondetails and documents that relate to the interfacing of the different exterior systems andcomponents that make up the envelope of the house before starting construction.Dryvit strongly urges EIFS contractors not to begin work on a project in which the constructionrequirements for EIFS application have not been fulfilled.WE AT DRYVIT ASK OUR EIFS CONTRACTORS TO INSIST ON THE FOLLOWING BEFORESTARTING AN EIFS INSTALLATION.Weather Barrier - A code-approved weather-resistant barrier shall be installed horizontallyoverlapping the course below in a weatherboard fashion. The minimum overlap is dictated by theapplicable building code.Ambient Temperature Requirements - A minimum temperature of 4 C (40 F) and rising duringinstallation and 24 hours thereafter shall be maintained.Substrates - Wall sheathing shall be securely fastened per applicable building code. There shallbe no planar irregularities greater than 6.4 mm (1/4 in) within any 1.2 m (4 ft) radius.Flashing at Openings - All openings shall be properly flashed per project design documents.Individual windows, that are ganged to make multiple units, shall have continuous flashing and/orjoints between them and shall be fully sealed.Decks - Provisions shall be made to ensure that the Dryvit system can be properly terminatedabove grade and at patios, decks, landings, etc. and that the required flashing is in place.Roof - Ensure that the roof has positive drainage, i.e., crickets or saddles. Metal roof flashingshall be installed in accordance with the guidelines set by the Asphalt Roofing ManufacturersAssociation (ARMA). Run-off diverters, i.e., kick-outs, must be installed where required.Utilities - Provisions must be made to ensure that the system terminates properly at lightingfixtures, electrical outlets, hose bibs, dryer vents, etc.3
