8500PRODUCT DATATechnical Data SheetSections19 1607 07Water RepellentsTECHNOLOGY // ADVANTAGES Composition -Nanotechnology driven high-performanceisooctyltriethoxysilane. Its smaller molecular structure allows fordeeper penetration increasing performance Excellent waterproofing - Penetrates deep within the concretechemically reacting within the pores and capillaries creating along-lasting hydrophobic surface that beads water 100% breathable - Non-film forming. Allows moisture within theconcrete to escape without adverse effects to the sealer. Does nottrap moisture Increases abrasion resistant - Reduces concrete dusting.Provides ease of maintenance, resist ASR / Alkali attack Protects against chloride ion penetration - Forms an effectivechloride screen dramatically reducing chloride ion ingresspreventing deicing salt / chloride damage Stops moisture intrusion - Resists wind-driven rain, preventsfreeze-thaw damage, spalling, pitting and cracking. Resists freeze thaw and thermal cycling damage Natural flat finish - Does not change surface appearance, UVstable will not breakdown with light exposure Can be applied to cured, honed and polished concrete - Idealfor horizontal surfaces exposed to pedestrian and vehicle traffic,compatible with silicate densifiers Water based - Low VOC’s, environmentally friendly Unrivaled industry leading 100 year warranty - Penetratesnever delaminates, never diffuses, peel or flakes will not discoloryellow or degrade from UV light exposure.TYPICAL PROPERTIES Resist organic growth - Resists mold, mildew, lichen, andefflorescenceAppearance - Milky white liquid (dries clear) Department of Transportation approved - Meets or exceedsDOT specificationsPackaging - 1 gallon (3.78 L), 1 gallon ultra concentrate (3.78 L) and55 gallon (208 L) drums Improves durability - Prevents capillary uptake of water and theaggressive substances dissolved in itVOC’S - 90g/L maximumFlash Point - 199 F (93 C boiling)Specific gravity - 0.97 Density - 8 lb/galK r e t eTe k I n d u s t r i e s I n c .66 River Road Hudson, NH 03051//855-573-8383//www.ghostshield.com2

8500PRODUCT DATATechnical Data SheetSections19 1607 07Water RepellentsAPPLICATIONApplication - Ready to Use (Continued)Surface Prep1. New “green” concrete must be properly cured. Concrete shouldobtain 80% of design strength, typically achieved within 14-28 days.2. The concrete substrate must be structurally sound and clean of oil,grease, dirt, wax, curing compounds, efflorescence, paints, previoussealers, adhesives and other contaminants that might interfere withthe penetration of the sealer. Power wash, acid etch or mechanicallyscarify as necessary to achieve the desired surface condition. Allowfor proper dry time before application. The surface-zone moisturecontent of the concrete should not exceed 4% wt. Do not apply ifstanding water is visible.3. Surface and air temperatures must be at least 40 F duringapplication. Surface and air temperatures should not exceed 95 F.Do not apply when temperatures are expected to fall below 32 Fwithin 8 hours or when rain is expected within 12 hours followingapplication. Keep material from freezing. If freezing conditions existbefore application, let the substrate thaw before application. Do notapply during inclement weather or when inclement weather isexpected within 12 hours.4. Crack, patching and expansion joint sealants can be appliedbefore or after application; always test for compatibility andadhesion.5. Protect people, property, vehicles, window glass, roofing materials,plastic products, shrubbery, landscaping and all surfaces not set fortreatment from overspray.Application - Ready to Use1. Always test a small area before application to ensure desiredperformance, aesthetics, coverage rates and to verify applicationtechnique. Let test area dry thoroughly, 5-7 days, before inspection.2. Stir material throughly before and during application. Do notdilute or alter material for purposes other than specified.K r e t eTe k I n d u s t r i e s I n c .66 River Road Hudson, NH 030513. Two wet-on-wet coats are needed to ensure complete coverage.Apply with a roller, brush or low-pressure non-atomizing sprayer.Apply to saturation and let the first coat penetrate for 5-10 minutesthen reapply a second coat in the same saturating manner. Lessmaterial will be needed for the second coat. Roll or broom out anypuddles until the sealer penetrates the substrate. If it starts to rain,stop treatment and cover the impregnated areas.Application - Ultra Concentrate1. Always test a small area before application to ensure desiredperformance, aesthetics, coverage rates and to verify applicationtechnique. Let test area dry thoroughly, 5-7 days, before inspection.2. Always mix the concentrate with 4 parts water prior to application.Distilled water is recommended for maximum performance. Stirmaterial throughly before and during application.3. Two wet-on-wet coats are needed to ensure complete coverage.Apply with a roller, brush or low-pressure non-atomizing sprayer.Apply to saturation and let the first coat penetrate for 5-10 minutesthen reapply a second coat in the same saturating manner. Lessmaterial will be needed for the second coat. Roll or broom out anypuddles until the sealer penetrates the substrate. If it starts to rain,stop treatment and cover the impregnated areas.Dry TimeTypical drying time is 4-6 hours at 70 F and 50% relative humidity.Cooler temperatures or higher relative humidity can extend thedrying time. Treated surfaces will be ready for pedestrian and vehicletraffic within 24 hours. Water repellency will continue to developwithin 7 days of application.//855-573-8383//www.ghostshield.com5
