APPLICATION INSTRUCTIONS95 Goodwin StreetEast Hartford, CT 06108Tel: 800-253-3539 Fax: 860-528-2802 www.dur-a-flex.com contact us@dur-a-flex.comDUR-A-WALL VCIMPORTANT! Read these instructions carefully several days prior to starting your work. Seek answers to any questions you mayhave before you begin. DUR-A-FLEX, Inc. maintains a Technical Staff that will be glad to answer your questions and give youadvice pertaining to your particular installation.DUR-A-WALL VC is applied by brush, roller and broadcastmethod. When recommended spread rates are followed, adouble broadcast of either MICRO or MACRO decorative chipwill produce a nominal 35-40 mil wall system.SURFACE PREPARATIONSurface must be clean, dry and free of all oil and grease.Please refer to the Surface Preparation Guide on our websitefor more information. No epoxy coatings should be appliedunless surface temperature is a minimum of 5 degrees Fabove dew point. See Dew Point Calculation Chart on ourwebsite for detailed instructions.MIXING AREASelect a convenient mix area and protect the surface fromspillage by covering with a layer of cardboard and sheet ofplastic. Be generous with the amount of space you allocate forthis function. The more comfortably your mixer works, the lesslikely you are to have a “mix error”. Make ready all necessarytools, mix and measure containers, etc. DO NOT MIX ANYEPOXY UNTIL READY FOR IMMEDIATE USE. Once hardenerand resin are combined, it must be used immediately. Applymasking tape wherever coating is intended to stop.DUR-A-WALL APPLICATION METHODNOTE – For masonry surfaces such as brick, block, ceramictile etc. (A pre-installation meeting is recommended todetermine surface finish.) Substrate finish will affect finalappearance of wall coating. Drywall must be finished to alevel #4 - #5 finish. DUR-A-BOND 90 joint compound isrecommended for adhesion. DUR-A-GARD and DUR-A-GLAZE# 4 epoxies are applied with a 3/8” nap roller. Coverage willvary depending upon porosity and texture of substrate.Multiple applications of filler material may be necessary. Sandor grind between coats to achieve a smooth surface.use DUR-A-WALL HP GRIPPER PRIMER. This will preventthe base coat from soaking into the sheet rock.B. Base Coat -Add 1 part DUR-A-GARD NO-SAG hardenerto 2 parts DUR-A-GARD resin by volume. Mix with a slowspeed Jiffler type mixer for 2-3 minutes. Apply at a spreadrate of 250 Sq Ft per gallon.C. Broadcast Coat – Using the Flaketech Hopper Gun that isconnected to an air compressor set at 20 - 30 psi, applythe vinyl chip into wet base coat at approximately nine SqFt per pound and allow to cure.D. Second Broadcast Coat – Remove loose vinyl chips bythoroughly scraping the surface with a trowel or wall paperbrush and apply a coat of DUR-A-GLAZE # 4 at 150 SqFt per gallon. Apply the vinyl chips at approximately ninesquare feet per pound using the Flaketech Hopper Gun thatis connected to an air compressor set at 20-30 psi.E. Seal Coat – Remove loose vinyl chips by thoroughlyscraping the surface with a trowel or wall paper brush andapply a coat of DUR-A-GLAZE # 4 at 150 Sq Ft per gallon.Allow to cure for 10-12 hours before sanding off bumpsand imperfections.TOPCOAT INSTRUCTIONSTwo coats of a urethane topcoat are applied for the DURA-WALL VC system. The urethane topcoats provide a highdegree of abrasion resistance and are available in high glossand satin finishes. Refer to the Chemical Resistance Chart forperformance characteristics to help determine which topcoatto use to meet the requirements of your particular application.IMPORTANT: Be sure to pour the hardener into the mixingbucket first, when working with the epoxy and vice versawhen working with the urethane. Always scrape thesides and bottom of mixing container to assure thoroughblending. Do not allow any water on coated surface for24-48 hours.NOTE: Tile grout lines may “mirror through” the finishedsystem even though the surface is smooth.A. Priming – When applying over concrete or block walls,DUR-A-WALL HP BLOCK FILLER is recommended to fillany pores in the substrate. When applying over sheet rock,8

SURFACE PREPARATIONGUIDELINESDUR-A-FLEX, INC. has developed this document to help Facility Owners, Architects, Engineers,Specification Writers, and Contractors gain a better understanding of the importance of a properly preparedsubstrate, and the methods to achieve an appropriate bond. This document is intended to be a generalguideline, for specific jobsite information, please contact your local DUR-A-FLEX Representative.There are many satisfactory methods of preparinga substrate to receive a DUR-A-FLEX flooringsystem. The preparation method is typically chosenbased on service requirements, time allowed forentire process and accessibility.PERSONAL PROTECTION EQUIPMENTIt is the responsibility of the surface preparationcontractor and the flooring contractor to insure thatall personnel are properly protected from hazards.DUR-A-FLEX is committed to promotingawareness regarding these potential hazards. AllDUR-A-FLEX products are rated according to theHazardous Material Identification System (HMIS).OSHA regulations specify when, where and howworkers are to be protected. These regulations andthe local OSHA officials should be consulted asnecessary to insure proper protection, compliancewith the law, and to avoid liability issues. Safetyand health issues should be addressed prior to thestart the job.TESTINGMOISTURE CONCERNSPlease refer to the Floor Evaluation Guidelines inthe Contractor’s Center of our website to assist indetermining the condition of the concrete.Testing For An Existing SealerTest to see if the floor is “sealed” by pouring asmall amount of muriatic acid on the floor inseveral spots. If it “froths” instantly, the floor isnot sealed. If the acid doesn’t froth immediately, asealer and/or paint is present and must be removedby scarifying, steel shot blasting or othermechanical methods.Salt Contamination TestingSalt contaminated slabs that contain steelreinforcement are very susceptible to corrosion ofthe reinforcing steel. As the steel corrodes itexpands causing cracking, delamination ofconcrete and any toppings bonded to it andeventually, structural failure of the slab. Obvioussigns of chloride or salt contamination are spalledconcrete with exposed, rusted reinforcing steel.Testing is recommended to determine the depth ofcontamination and the extent of corrosion activity.A Litmus Test for pH will determine the presenceof chloride or acid contamination, if the pH isbelow 10.Bond TestThe purpose of the bond test is to make surepreparation method is adequate for the primer tobond to the substrate. The test is done only whenapplying MMA systems. For more information onbond test refer to CRYL-A-PRIME data sheet onour website @ www.dur-a-flex.com.12

Surface Prep Guidelines (Continued)REMOVAL AND REPAIRASTM D 4258-83 Standard practice for surfacecleaning concrete for coating.This practice includes surface cleaning of concreteto remove grease, dirt, and loose material prior tothe application of coatings. Procedures includevacuum cleaning, air blast cleaning, watercleaning, detergent water cleaning, and steamcleaning.Removal of bond inhibiting contaminantsThis includes, but is not limited to removal of oils,grease, wax, sealers, curing compounds, laitance,salts and any other hydrocarbon based materials.This will ensure that a good bond takes placebetween the resinous flooring and the concretesubstrate.REASONS FOR SURFACE PREPARATIONSurface preparation of a concrete substrate isrequired to remove surface laitance to create asurface profile and porosity for adhesion ofpolymer floor systems.METHODS OF SURFACE PREPARATIONCare should be taken to define the degree ofabrasion required for the coating system so that theconcrete will not be eroded beyond what isnecessary. All concrete surfaces should be abradedto remove laitance and contaminants. Thefollowing Table describes the required profilesaccording to the ICRI guidelines for variouscoating systems.CoatingRemoval of Adhesives, Mastics and MembranesIn many retrofit projects, existing tile, VCT orsheet goods are being replaced with polymerflooring systems. Removal of the floor finish willoften leave a layer of some type of mastic,adhesive or membrane. In thin applications thesematerials can often be totally cleaned up byshotblasting the concrete. In thicker applications,the steel shot will tend to bounce, requiringadditional preparation with the use of scarifyingequipment or possibly even the use of chemicalstrippers. Wherever possible, consult the DUR-AFLEX Tech Service Department or your localDUR-A-FLEX Flooring Contractor and schedule asite visit to investigate the best removal methods.Removal of Existing Seamless FloorLike mastics and adhesives, the need to remove anexisting seamless floor will occasionally arise.There has been much progress made in thedevelopment of equipment for removal ofresurfacers. Typically, removal requires a heavygrinder with “rotating heads”. These heads can beoutfitted with different “teeth” or carbide “blades”for removal of a particular type of overlay.SealersHigh-BuildSelf LevelingPolymerOverlayCoatingThickness3 mil10-40 mil50 mils-1/8”1/8-1/4”ConcreteSurfaceProfile (CSP)CSP 2-3CSP 3-4CSP 4-5CSP 5-7ShotblastingShotblasting is the recommended method ofsurface preparation of concrete for most polymerfloor installations. Shotblast equipment utilizes analloy wheel spinning at high speeds to throw smallsteel particles at the substrate in a controlled, dry,99% dust-free operation. This process removessurface contamination, adds profile and vacuumsthe concrete clean in one process. The size andangularity of shot, along with the travel speed ofthe unit, can be adjusted to determine the degree ofthe surface profile. Because shotblasting is a drypreparation process, it allows the installation tobegin immediately after completion of prep(surface must be dry before blasting). Shotblastingwill also identify weak areas in the surface of theconcrete.NOTE: When selecting shotblastpreparation for thin film coating systems (under 20mils) be aware that a blast pattern or track linesmay be visible.-213

Surface Prep Guidelines (Continued)Diamond GrindingDiamond grinding should only be used in areasinaccessible to shotblasting and then only withcoarse diamond wheel.ScarifyingScarifying is primarily used for the removal ofdeteriorated concrete, coatings and polymerflooring systems.Hand ToolHand tool preparation consists of the use ofmechanical tools and equipment designed toabrade or chip away the surface of the concrete.Common tools available include chippinghammers, hand held diamond grinders andconcrete crack chasing saws. These tools aretypically used to make keyways, prepare edgesagainst walls and columns.TYPES OF SUBSTRATESRegular ConcreteRegular concrete surface must be prepared with asteel shot-blast machine, scarifier or diamondgrinder. Floors with oil, grime and grease r before preparing. Allow floorto dry. Good ventilation, fans and/or auxiliary heatwill accelerate drying time. Do not use oil firedportable heaters.Replacement of Structurally DeterioratedConcreteReplacement of structurally deteriorated concretemust be done in accordance with The InternationalConcrete Repair Institute (ICRI) Bulletin.Patching material must be a DUR-A-FLEXapproved patching material.Make sure ofminimum cure time before installation of resinousflooring.DUR-A-FLEX flooring Contractorsshould be contracted whenever possible tocomplete these repairs appropriately.Fiber Filled ConcreteFiber filled concrete must be burned with apropane weed burner, swept and vacuumedperfectly clean and then primed. When primer hascompletely cured, the floor must be sanded andtack ragged (This step may not be necessary forthick resurfacing systems).Quarry/Ceramic TileQuarry/Ceramic tile have been successfullyresurfaced on many projects without removal oftile and setting bed. A site investigation along withcores through the entire slab will help identify thetype of setting bed, the existence of anywaterproofing membranes, additional toppings, orother unusual existing conditions. Water trappedwithin the floor will create long-term sanitationand performance problems.If the tile is well bonded and placed over anunsaturated latex setting bed, the floor may beresurfaced as follows: Surface must bemechanically abraded with a steel shot-blastmachine, scarifier or diamond grinder andvacuumed perfectly clean. “Tack rag” area toremove dust and to soften surface. Apply DUR-AFLEX recommended Poly-Crete or Hybri-Flexsystems or DUR-A-GLAZE TIECOAT II orCRYL-A-PRIME P-101 with CRYL-A-BONDMT primer to the entire area immediately andallowed to cure.Existing Epoxy Coating/ResurfacerExisting seamless floors may be resealed orresurfaced from time to time due to excessive wearor the need to change the appearance or skidresistance of the floor. The existing floor shouldfirst be cleaned and degreased with EZ-CLEANfloor cleaner/degreaser.It must then bemechanically abraded with a floor-sandingmachine or a steel shot blast machine to totallyremove gloss. Vacuum perfectly clean. “Tackrag” area to remove dust and to soften surface.Apply DUR-A-GLAZE TIE-COAT II to entirearea immediately followed by subsequent epoxycoatings.-314

Surface Prep Guidelines (Continued)PlywoodThe plywood substrate must be sound and nonflexing under the expected load. Typical plywoodsubstrate must be exterior or marine grade, new,clean, and smooth finish (NO KNOTS).Cast in place Concrete and Ceramic Tile:Use DUR-A-GLAZE RAPID PATCH for cracks,holes, spalls, and voids in concrete up to ¼” thick.Multiple applications of filler material maybenecessary. Sand or grind between coats toachieve a smooth surface.Two layers with staggered joints are required.Plywood should be positively fastened to theexisting surface with a high quality constructionadhesive as well as a 6” screw pattern.NOTE: Tile and block grout lines may “mirrorthrough” the finished system even though thesurface is smooth.For further information on plywood substrates,please contact your local sales representative orDUR-A-FLEX technical department.WallsFor Dur-A-Wall Applications:Block wall: Apply Dulux (ICI) block filler to fillpores over new or existing concrete blockfollowing manufacturer’s instructions.CRACKS AND JOINTSRefer to Joint Guidelines for complete joint detailson our website in the Contractor Center section @www.dur-a-flex.com.Use DUR-A-GLAZE RAPID PATCH for cracks,holes, spalls, and voids in concrete up to ¼” thick.Drywall: Drywall must be finished to a level #4 or#5 finish prior to coating. Prime with ICIGRIPPER Multipurpose primer or GLIDDENGRIPPER primer. Substrate will affect finalappearance of wall coating.0814-415

CLEANING GUIDELINESWHY CLEAN YOUR FLOOR?Appearance: Your floor will look its best when it is clean. By establishing a scheduled cleaning program, the floor will continue tolook and perform as it did when it was first installed.Safety: No matter how aggressive the texture of your floor, if it is not cleaned properly, it can present a slip hazard. Emulsifying,rinsing and drying your floor properly will reduce the risk of a slip and fall incident.Note: Wet environments need to be kept dry as possible to prevent slip and falls. Proper signage, non-slip shoes, floor fans, andwalk-off mats will help prevent slip and falls in any facilityService Life: The lifetime of your floor will depend upon how well you clean it. In aggressive use areas (i.e. kitchens andmachine shops) contaminants such as oil, dirt, and grease work with water and bacteria to break down the floor.FLOOR CLEANING PROCESS & TOOLSThe best way to clean a Dur-A-Flex floor is to use the recommended cleaning product and follow a six-step process.
