Samples of the actual coatingwere used as test GS4 PRODUCT DESCRIPTIONS tonkote GS4 is a two-component, solvent-free, general service, epoxy coating. It is formulated to increase abrasion and chemi-cal resistance while improving cleanability. Stonkote GS4 is easilyapplied and hardens to an attractive gloss , APPLICATIONSS tonkote GS4 is a general service coating designed for usewhenever a high solids, corrosion-resistant, gloss coating isrequired.

2 It may be applied on various substrates to both verti-cal and horizontal surfaces. Some applications of Stonkote GS4include: In conjunction with various Stonhard flooring systems Protection of concrete surfaces exposed to abrasive or cor-rosive environments For substrates requiring a protective coating that is easilycleaned and maintainedPRODUCT ADVANTAGES 100% solids Long-term abrasion and corrosion resistance Excellent bond strength assures good adhesion Protects against moisture penetration Bonds to many different substrates Durable, gloss finish permits easy cleaning and maintenance Factory proportioned packaging ensures consistent, highquality, simplified mixingPACKAGINGS tonkote GS4 is packaged in units for easy handling.

3 Each unitconsists of one carton containing:4 foil bags of Part A (curing agent)4 poly bags of Part B (resin)COVERAGEA pproximately 400 sq. sq. m per unit at 4 mil thicknessover a porous substrate (unsealed concrete, uncoated mortarsystems, etc.).Approximately 750 sq. sq. m per unit at 4 mil thicknessover a sealed substrate (primed concrete, coated mortar sys-tem, etc.) STORAGE CONDITIONSS tore all components of Stonkote GS4 between 60 to 85 F/16to 29 C in a dry area. Avoid excessive heat and do not shelf life is 3 years in the original, unopened GS4 is available in Clear and 14 standard colors are available upon PREPARATIONP reparing Stonhard Flooring SystemsBefore coating a Stonhard floor, all trowel marks and surfaceimperfections must be removed to produce a smooth the floor using a floor grinder with medium stones andvacuum using an industrial wet/dry vacuum to remove all dustparticles.

4 The Stonhard floor is now ready to be coated withStonkote Concrete SubstratesProper preparation is critical to ensure an adequate bond. Thesubstrate must be dry and free of all wax, grease, oils, fats, soil,loose or foreign materials and laitance. Laitance and unbondedcement particles must be removed by mechanical methods, ,abrasive blasting or scarifying. Other contaminants may beremoved by scrubbing with a heavy-duty industrial detergent(Stonkleen TD9) and rinsing with clean water. The surface mustshow open pores throughout and have a sandpaper recommendations or additional information regarding sub-strate preparation, contact Stonhard s Technical use over a Stonhard floor, no primer is necessary. In mostcircumstances Stonkote GS4 is self-priming over concrete, how-ever, in certain circumstances Stonkote GS3 or HT Primer arerecommended to ensure maximum product Stonhard Technical Service for further primer GS4 is supplied in factory proportioned quantities.

5 Toachieve thorough and proper mixing, the Stonkote GS4 mustbe mechanically mixed using a heavy-duty, slow-speed drill (400to 600 rpm) with a Jiffy Mixer. Empty the contents of Part Binto a mixing container and pre-mix to assure the suspension ofsolids. Add Part A and continue to mix to a uniform consistencyfor 2 minutes. Avoid high speed mixing that will entrain air intothe mix. Thorough mixing of the two components is required. POT LIFEA fter mixing, Stonkote GS4 has a working time of approximate-ly 35 minutes at 77 F/25 C. The working time may varydepending on ambient and surface GS4 should be applied at ambient temperatures of 60to 85 F/16 to 29 C and humidity below 80%. Stonkote GS4 isapplied with a rubber squeegee and medium nap roller.

6 Theroller is used to remove squeegee lines and smooth out thesurface. A brush may be used where necessary. Stonkote GS4may be applied at variable thicknesses ranging from 4 to 6 milminimum dry film thickness. Each additional coat may beapplied when the surface is tack-free, which is about 8 questions regarding the application of Stonkote GS4should be directed to Stonhard s Technical Service surface of Stonkote GS4 will be tack-free in 8 hours at77 F/25 C. The coated area may be put back in service in 24hours. Ultimate physical characteristics will be achieved in Apply only on a clean, sound and properly prepared sub-strate. Minimum ambient and surface temperatures are 60 F/16 Cat the time of application. Application and curing times are dependent upon ambientand surface Use these materials only in strict accordance with the manu-facturer s recommended safety procedures.

7 Dispose of wastematerials in accordance with government regulations. Accetone is recommended for clean up of the unreactedStonkote GS4 material. Use these materials only in strictaccordance with manufacturer s recommended safety proce-dures. Dispose of waste materials in accordance with govern-ment regulations. The reacted material will require mechanicalmeans of removal. The selection of proper protective clothing and equipment willsignificantly reduce the risk of injury. Body covering apparel,safety goggles or safety glasses and impermeable gloves arerequired. If material is ingested, immediately contact a physician. DONOT INDUCE VOMITING. In case of contact, flush the area with copious amounts waterfor 15 minutes and seek medical attention.

8 Wash skin withsoap and water. Use only with adequate Procedures for maintenance of the flooring system duringoperations are described in the Stonkleen Floor CleaningProcedures Brochure. For environments not referenced in the Chemical ResistanceGuide, consult Stonhard s Technical Service Department forrecommendations. Safety Data Sheets for Stonkote GS4 are available on line under Tech Info or upon request. A staff of technical service engineers is available to assist withproduct application or to answer questions related toStonhard s products. Requests for technical literature or service can be madethrough local sales representatives and offices, or corporateoffices located worldwide. The appearance of all floor, wall and lining systems will changeover time due to normal wear, abrasion, traffic and , high gloss coatings are subject to a reduction ingloss, while matte finish coatings can increase in gloss levelunder normal operating conditions.

9 Surface texture of resinous flooring surfaces can change overtime as a result of wear and surface contaminants. Surfacesshould be cleaned regularly and deep cleaned periodically toensure no contaminant buildup occurs. Surfaces should beperiodically inspected to ensure they are performing asexpected and may require traction-enhancing maintenance toensure they continue to meet expectations for the particulararea and conditions of use.
