BecauseManningtonCommercialResilientSheetFlooringproductsareintendedforuseinhigh-trafficareas,underfloor selection and preparation are especially important. In most cases, remove all existing floor coverings before installing these commercial products. (You must strictly follow all federal, state, and local regulations regarding the removal of existing flooring.) Furthermore, all concrete under floors must be tested for moisture beforestartingtheinstallation.ManningtonrequiresthattheconcretebetestedformoistureusingeithertheanhydrouscalciumchloridetestfollowingASTMF1869proceduresandorthein-siturelativehumiditytestfollowingASTMF2170.MaximumpermissibleMVERaredeterminedbyproductconstructionandadhesivetype(seechartabove).NOTE:Whileeitheroftheseindustryacceptedmoisturetestingmethodsmaybeused,theresults are not exchangeable, if both tests are performed they must both be in the acceptable range to be considered valid.

Handling proceduresIt is imperative to maintain the material, adhesive, and job site at a minimum temperature of 65°F and a maximumtemperatureof85°Ffor48hoursbefore,during,andaftertheinstallation.Ifthematerialhasbeenstored at colder temperatures, it will need to be unrolled and allowed to relax overnight before proceeding with theinstallation.WhenusingV-95adhesive,makesuretomaintaintheadhesive,floorcovering,andjobsiteataminimumtemperatureof65°Fforaminimumof48hoursbefore,during,andaftertheinstallation.

NOTE: If the flooring contractor elects to install new floor covering over an existing floor covering, the flooring contractor assumes all responsibility as to the suitability and continued performance of the existing floor covering.Ifremovalofexistingresilientfloorcoveringisrequired,followallrecommendedResilientCoveringFlooringInstitute(RFCI)workpracticesatwww.rfci.com.Pleasebeawarethatinstallingtheseproductsoverexistingflooringmayreducetheirexcellentindentationresistance.Theseproductsmayalsobeinstalledoverproperlyprepared and approved wood panel or wood composition panel underlayments on wood subfloor systems.

Flash coving resilient sheet productsAllManningtonresilientsheetgoodscanbeinstalledusingtheflashcovingmethod.Thisedgingtechnique,often preferred by hospitals and other health care facilities, is a process of extending the resilient flooring up the wall to create a wall base. Normally, the floor covering is extended up the wall to a height of 4” to 6”.

As with all resilient installations, proper preparation of the work area is critical to the success of the installation. Clean the underfloor carefully and make certain it is structurally sound.

Concrete floors with a radiant heating system are satisfactory, provided the temperature of the concrete floor does not exceed 90°F at any point. Before installing the flooring, the heating system should be turned on to eliminate residual moisture.

C. Existing resilient floor coveringsTo achieve maximum product performance, fully adhered Mannington Commercial LVT should not be installed over existing resilient floor coverings.

If the concrete is glazed or very smooth, it must be thoroughly sanded or shot blasted to assure proper adhesion. Remove all dust by vacuuming.

Adhesion (bond) testA bond test of at least 24 hour duration should be performed. Recommended to cut Mannington tile into 9”x 9”piecesandinstallthemusingtherecommendedadhesive.Thesetestpatchesshouldremaininplaceforaminimum of 24 hours to determine if there is good bond to the subfloor and also to observe if there is sufficient transfer of adhesive both to the subfloor and to the back of the floor tile. Removing the test patches from the subfloor should be difficult with most of the cured adhesive remaining bonded to the subfloor. If proper bond is not accomplished, do not proceed with the installation.

Important Make sure you inspect carpet modules prior to installation. No claims will be honored if modules are installed with visible defects. Read all instructions prior to beginning installation.

Site and modular material conditioning is a mustModules must be conditioned to room temperature for 24 hours prior to installation. Floor temperatures must be a minimum of 65° for 24 hours prior to installation.Floortemperaturecanusuallyvary5-10°lowerthanroomtemperature.Relativehumiditymustbebetween10%-65%maximumfor24hourspriortoinstallation.Theseconditionsmustalsobemaintainedfor48hoursaftercompletionofinstallation.

Surface preparationDust, dirt, debris, and noncompatible adhesive must be removed before installation begins. Surfaces must be smoothandlevelwithallholesandcracksfilledwithalatexbasedPortlandcementpatchingcompound.

Latex adhesivesMustberemovedandfloorssandedorcoveredwithaskimcoatofPortlandpatchingcompound.Latexadhesivemay also be covered with TRISEALadhesivesealer(800-367-4583).

Note: Failure to remove or seal old latex adhesive may cause installation failure, plasticizer migration, shifting, buckling or edge curling; these conditions will not be covered under warranty.

Cut back adhesives Must be wet scrapped and covered with 2 applications of TRISEAL(800-367-4583).

Note: Failure to remove or seal old cut back adhesive may cause installation failure, plasticizer migration, shifting, buckling or edge curling; these conditions will not be covered under warranty.

Moisture testingSubfloorsurfacesmustbetestedformoisturecontent.Itistheresponsibilityofthegeneralcontractorand/orinstallertoperformmoisturetestpriortostartingtheinstallation.MANNINGTONrecommendscalciumchloridetests be performed to detect the presence of moisture. Acceptable results require that moisture content does not exceed 3lbs. Per 1,000 square feet per 24 hours. Mannington also accepts the Relative Humidity ASTME-F-2170testmethod.Acceptable moisture leves are 75% maximum relative humidity. Alkalinity must haveamaximumPhlevelof9orless.ContactTechnicalServicesforrecommendationsformoisturereadingsover3lbs.,75%RHorPhlevelsover9.

Full adhesive methods Mannington recommends a full spread adhesive system for the most trouble free installation.
