Roppe Rubber Stair TreadsRaised and Smooth ProfilesProduct DataSection 9Resilient FlooringInstallation6.1 General Preparation and ConditioningRead the literature concerning the product description, product limitations, product installation,adhesive & ROPECC Epoxy Caulking Compound information, product maintenance, andwarranty before installing stair treads. All materials are to be delivered to the installation locationwithin 48 hours of installation in its original packaging with labels intact. Store products in a dryarea protected from the weather with temperatures maintained between 65 F (19 C) and 85 F(30 C). DO NOT stack pallets. Remove all plastic wrapping and strapping from the pallets andun-box all material in the installation area at least 48 hours prior to installation. Stair Treadsmust be stored horizontally and placed on a smooth, level, dry surface, which supports theentire width of the stair treads. The installation area, substrate, rubber stair treads, associatedmaterial and adhesive are to be maintained between 65 F (19 C) and 85 F(30 C) for at least 48hours before installation, during installation, and thereafter. In addition, the subfloorstemperature range must also be between 65 F (19 C) and 85 F(30 C) prior to installation,during installation and maintained thereafter. Inspect all material for proper type and color.Conduct the proper moisture emission and pH testing on the substrate. Proceed with theinstallation only when the conditions are proper and correct. A bond test using ROP360 AcrylicTile and Stair Tread Adhesive, ROP435 Epoxy Adhesive, ROP535 Solvent-Free TwoComponent Polyurethane Adhesive (required for metal and recommended non-poroussubstrates, and for butting stair tread installations), ROPECC Epoxy Caulking Compound, andROP Quik-Stik Adhesive Tape must be conducted throughout the area approximately 50 feetapart and one test must be conducted per flight of stairs, in addition to each connecting landingareas at least one week prior to the scheduled installation to ensure the surface is suitable. After72 hours, there should be an unusual amount of force to lift the stair treads from the substratewith adhesive/ Quik-Stik Tape and ROPECC Caulking Compound or bonding to both the stairtread and the substrate. DO NOT proceed with the installation if the concrete subfloor hasdarkened, if visual moisture is present or if adhesive is still wet. Each is clear indications ofsubfloor moisture problems. Close the area to traffic during stair tread and flooring installation.Install stair treads and accessories after other finishing operations, including painting, havebeen completed. Do Not expose installed stair treads to dollies loaded with heavy material ordrag items across stair treads to prevent stair tread nosing from cracking or adhesive failure.Prevent the back of the stair treads from becoming contaminated and protect the face fromdamage. If the back of the stair treads becomes soiled prior to installation, clean with denaturedalcohol, rinse and a clean white cloth, and let dry. Warning: Follow all local, state, and federalstandards and practices for the proper removal and disposal of flooring, adhesives, or othermaterials. Follow all local, state, federal, and manufacturer’s safety standards for the use of allproducts and equipment.6.2Subfloor/Substrate Inspection and Preparation6.2.1 All subfloors/substrates must be inspected prior to installation. All substrates must beclean, smooth, permanently dry, flat, and structurally sound. The substrate must be free ofPage 1 of 21 Roppe Corporation, Printed in the U.S.A.
Roppe Rubber Stair TreadsRaised and Smooth ProfilesProduct DataSection 9Resilient Flooringmoisture, dust, sealers, primers, paint, oxidation, curing compounds, parting agents, residualadhesives, adhesive removers, hardeners, resinous compounds, solvents, wax, oil, grease,asphalt, gypsum compounds, alkaline salts, excessive carbonation or laitance, mold, mildew,any other extraneous coatings, films, materials and all other foreign matter which mightinterfere/restrict proper adhesive bonding. DO NOT use sweeping compounds, solvents, citrusadhesive removers, or acid etching to clean the substrate. DO NOT install over gypsum-basedor plaster based leveling or patching compounds. DO NOT install new floor covering over oldfloor covering, as the old floor covering may not be adequately bonded, hide possible structuraldefects, or cause plasticizer migration into the new stair treads and flooring. In renovation orremodel work, remove all existing* adhesive residue so that 100% of the overall area of theoriginal subfloor/substrate is exposed. Follow The Resilient Floor Covering Institute’s (RFCI)“Recommended Work Practice for Removal of Existing Floor Covering and Adhesive, and allapplicable industry, local, state, and federal standards. Care must be taken to analyze theconditions and correct any problems prior to installation. Follow the manufacturer’srecommendations for any patching or underlayment materials, excluding gypsum based orplaster based levelers or patching compounds.*Some previous manufactured asphaltic “cutback” contained asbestos. For removal instructions,refer to the Resilient Floor Covering Institute’s publication “Recommended Work Practices forRemoval of Resilient Floor Covering”.6.2.2 Concrete substrates on all Grade Levels must be tested in accordance with ASTM F 1869Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor UsingAnhydrous Calcium Chloride or ASTM F 2170 Standard Test Method for Determining RelativeHumidity in Concrete Floor Slabs using in situ Probes to quantitatively determine the amount ofmoisture vapor emission at least one week prior to the installation. Caution: ASTM F 1869 orASTM F 2170 tests cannot predict long-term moisture conditions of concrete slabs. Moisturetesting only indicates moisture conditions at the time the tests are performed. Before conductingASTM F 1869 or ASTM F 2170 test, the installation area must be maintained between for 65 F(19 C) and 85 F (30 C) for at least 48 hours prior to testing, during testing and thereafter. Inaddition, the concrete’s temperature range must also be identical to that of the installation area.Conduct three test for the first 1,000 sq. ft. and one additional test for each 1,000 sq. ft. orfraction thereof per grade level. The Vapor Emission Rate shall not exceed 5.0 lbs and RelativeHumidity Test shall not exceed 75% when using Roppe 535U “Universal” Urethane EnhancedEpoxy, ROP435 Epoxy Adhesive and ROPECC Epoxy Caulking Compound. ROP360 VaporEmission Rate shall not exceed 4.0lbs and Relative Humidity Test shall not exceed 70%. QuikStik Adhesive Vapor Emission Rate shall not exceed 3.0lbs and Relative Humidity Test shall notexceed 65%. If the substrate does not meet the above noted requirements, the flooring shall notbe installed until the problem has been corrected. DO NOT install flooring if there is hydrostaticpressure. Every concrete floor slab on-grade or below grade to receive resilient flooring shallhave a permanent, effective moisture vapor retarder installed below the slab. A pH test must beperformed to test for excessive alkalinity using a pH pencil or litmus paper and deionized water.A scaly, sandy, or powdery surface is an indication of some form of contaminant, usuallyexcessive alkalis or an alkali-silica residue. A pH reading higher than 8 is an indication of aPage 2 of 21 Roppe Corporation, Printed in the U.S.A.
Roppe Rubber Stair TreadsRaised and Smooth ProfilesProduct DataSection 9Resilient Flooringpotential problem and the concrete must be neutralized by rinsing with clear water. Apply clearwater with a mop and allow to dry. Re-rinse with clear water, allow to dry and retest to ensurepH level is within acceptable range of 5 to 8 on the pH scale. Continue to neutralize until the pHlevel is acceptable. The testing of concrete for alkalinity indicates the degree of alkalinity only atthe time the test is conducted, and cannot be used to predict long-term conditions. Moisture andalkali salts in the concrete can cause the following problems after installation: adhesivedeterioration, bumps, ridges, bubbles, discoloration, mold, mildew, bacteria growth,efflorescence, tile shifting, tile releasing, tile peaking, or sheet seam curling. DO NOT installover burnished (slick troweled) concrete to avoid adhesive and underlayment patch or selfleveling bonding problems due to the non-porosity of the concrete finish. Corrective measuressuch as bead blasting (shot blasting) or scarifying must be performed prior to installation. Theconcrete slab must be of good quality, standard density concrete with low water/cement ratiosconsistent with placing and finishing requirements, having a maximum slump of 4”, a minimumcompressive strength of 3500 psi, and following the recommendations of ACI Standard 302.1R96 for class 2 or call 4 floors and the Portland Cement Association’s recommendations for slabson ground. Joints such as expansion joints, contraction joints, isolation joints, saw cuts, controljoints, grooves or other moving joints shall not be filled with patching compound or covered withresilient flooring. Expansion joint covers designed for use with resilient flooring should be used.Any non-moving surface cracks, depressions, and other irregularities shall be filled andsmoothed with a high quality grade Portland cement-based, water resistant, non-shrinking, nonstaining, mildew resistant, alkali resistant underlayment having a minimum compressivestrength of 3500 psi after 28 days. Some underlayments may fail under excessive weight; anepoxy caulking compound may be required for certain repairs. Mechanically cleaning thesubstrate by shot-blasting, scarifying, or sanding shall be performed to achieve a flat, smooth,clean surface to prevent irregularities, roughness, or other defects from telegraphing through thenew resilient flooring. The surface of the concrete shall be flat to within the equivalent of 3/16” in10 feet, as described in ACI 117R. The surface shall be cleaned of all loose material byscraping, brushing, vacuuming, or other methods, or a combination thereof, immediately beforecommencing installation of resilient flooring. Follow the proper safety practices during thepreparation and installation. Follow the recommendations of the American Concrete Institute(ACI 302.1R, Guide for Concrete Floor and Slab Construction; ACI 360.R, Design of Slabs onGrade; ACI 223, Standard Practice for the Use of Shrinkage-Compensating Concrete); TheAmerican Society for Testing and Materials (ASTM F 710, Standard Practice for PreparingConcrete Floors and Other Monolithic Floors to Receive Resilient Flooring), and the AmericanNational Standards Institute (ANSI A157.1, Recommended Practice for Concrete Floor and SlabConstruction) for the preparation of concrete to receive resilient flooring. Refer to 6.2.1.6.2.3 Wood subfloors to be used as subfloors/substrates are to follow the proceduresrecommended in 6.2.1 and 6.2.2. Wood subfloors should be of double layer construction with aminimum thickness of 1”. Crawl spaces underneath wood subfloors shall be in compliance withlocal building code ventilation practices and have clearance of at least 18” of cross-ventilatedspace between the ground level and joists. Wood joists should be spaced on no more than 16”centers. Place a moisture retarder; having a maximum rating of 1.0 perm, on the top of theground under the wood subfloor overlapped at least 8”.

Use APA approved exterior grade plywood if finished floors are subjected to moisture.OSB, lauan, maranti, solid-core mahogany, waferboard, particleboard, chipboard, flakeboard,tempered hardboard, glass mesh mortar units or cementitious tile backer boards, sheathinggrade plywood, preservative-treated plywood, or fire-retardant treated plywood are notrecommended as some manufacturers may use resins or other adhesives in the manufacturingof the product that may cause discoloration or staining of the flooring. Wood subfloor movement,flexing or instability will cause the flooring installed to release, buckle or become distorted. Donot proceed with the installation until corrective measures have been made. The warranties,performance, installation, and use are the responsibility of the manufacturer and/or contractor.DO NOT use plastic or resin filler to patch cracks. DO NOT use cement or rosin coated nails orstaples or solvent-based construction adhesive to adhere the plywood. Installation on a sleeper,a wood subfloor system constructed over the top of concrete, is not recommended. Installationdirectly over Sturd-I-Floor panels is not recommended. All wood subfloors, single constructionplywood floors, single and/or double tongue-and-groove strip floors, and wood plank floors mustbe prepared to receive resilient flooring in accordance with federal and industry standards.Follow the recommendations of the APA, The Engineered Wood Association,Design/Construction Guide, Residential and Commercial, and ASTM F 1482, Standard Guide toWood Underlayment Products Available for Use Under Resilient Flooring, for the installation andproper construction of the panels to receive resilient flooring. It is the contractor’s responsibilityto determine if the subfloor is acceptable to receive the flooring.6.2.4 Cementitious Terrazzo and ceramic floors to be used as subfloors/substrates are to followthe procedures recommended for concrete in 6.2.1 & 6.2.2. Ceramic tile must be solidlyadhered and all loose tiles must be removed and repaired or replaced. Ensure all glazed,sealed, smooth, and/or shiny surfaces are properly sanded and cleaned. Fill all grout lines andother irregularities with a manufacturer’s recommended Portland cement-based underlaymentwith a minimum compressive strength of 3500 psi. The subfloor must be structurally sound.Inspect and ensure there is an adequate bond of the old flooring to the original substrate. Do notinstall over epoxy based terrazzo. Cementitious terrazzo must first be sanded to remove allfinishes, and then cleaned. Conduct a bond test with adhesive to ensue a successful bond canbe achieved before installing. Roppe will not warranty the product if there is a bond failurecaused by problems relating to the old flooring.6.2.5 Metal floors to be used as subfloors/substrates must be thoroughly cleaned of anyresidue, oil, paint, sealer, rust, and oxidation and properly sanded/grinded to provide a smooth,level, clean substrate to receive stair treads and flooring. Metal floors and other substrates canonly be slightly flexing. Do not install over extremely flexing substrates. The stair treads andflooring must be installed within 12 hours after sanding/grinding to prevent the metal from reoxidizing. The metal subfloor shall be structurally sound. Deflection of the metal can cause abond failure between the adhesive, Quik-Stik Adhesive Tape, ROPECC Epoxy CaulkingCompound and the metal substrate. It is the contractor’s responsibility to decide the feasibility ofthe application, and Roppe Corporation will not be held liable for failures caused by flexing orPage 4 of 21 Roppe Corporation, Printed in the U.S.A.

On an extremely smooth, non-porous, metal substrate, alonger “tack up” may be required in order to prevent the adhesive from oozing between theseams. Refer to 6.2.1. Caution: The installation of Stair Treads, risers or other flooring materialwill not prevent deterioration of metal substrates from occurring.6.3 Adhesive Application6.3.1 ROP360 Acrylic Tile and Stair Tread Adhesive:ROP360 Acrylic Tile and Stair Tread Adhesive is a solvent free, high strength, acrylic adhesive forindoor installations over recommended and properly prepared concrete and wood subfloors only,on grade or above grade. Use of this adhesive is limited to casual foot traffic, in areas where thereare no lateral shear stresses or rolling loads, nor in areas that will not be subjected to topicalmoisture or liquids. (ROP360 must be used in combination with ROPECC Epoxy CaulkingCompound). Do Not use ROP360 to install Butting Stair Treads. For Butting Stair TreadsInstallations, refer to ROP535U Adhesive and ROP435 Epoxy Adhesive Sections. Caution:Before applying the recommended Roppe Adhesive or ROPECC Epoxy Caulking Compound,the stair tread, riser and stringer’s entire backing must first be thoroughly cleaned withDenatured Alcohol (always follow manufacturer’s recommendations, cautions and warningsetc.) and a clean white cloth to remove contaminates which could interfere with the bondingprocess. Once cleaned with Denatured Alcohol, allow backing to dry completely before applyingrecommended Roppe Adhesive or ROPECC Epoxy Caulking Compound and then test toensure a successful bond can be achieved. ROP360 Spread coverage using a 1/32” x 1/16” x1/32” “U” notch trowel is approximately 200-300 square feet per US gallon on a smooth or nonporous substrate. Coverage will vary according to the type of surface, surface texture, spreadingangle, and adhesive temperature. Note: Over extremely porous or rough concrete, a 1/16”x 1/16”x 1/16” Square notch trowel may be required (125-184 sq/ft/gal). Over porous substrates, allowadhesive to “flash-off” for 10 minutes before installing. Over smooth or non-porous substrates,allow adhesive to “flash-off” 20 minutes before installing. Approximate Working Time: 20-30minutes (depending on substrate temperature, humidity & trowel size). At least 90% transfer tothe products backing is required.Calculated VOC’s: ROP360 Acrylic Tile and Stair Tread Adhesive Calculated VOC’s accordingto California SCAQMD Rule #1168: 13 grams per liter of coating.
