EUCO-GUARD VOX

V.O.C. COMPLIANTCONCRETE DECK SEALER

EUCO-GUARD VOX is a V.O.C. compliant deeppenetrating liquid sealer designed to protectconcrete surfaces, decks, pavements and surfacesagainst adverse effects of salt contamination,moisture and weathering. EUCO-GUARD VOX re-acts chemically with the concrete surface to pro-vide a highly effective chloride screen and waterbarrier. EUCO-GUARD VOX is provided as a con-centrate which is easily mixed with potable waterat the job site and applied to both new and oldconcrete surfaces.

PRIMARY APPLICATIONl Parking structuresl Highwaysl Lane barriersl Bridgesl Rampsl Marine platformsl Auto/truck repair baysl Driveways and sidewalksl Exterior concrete

FEATURES / BENEFITSl V.O.C. compliantl Provides an efficient, continuous chloride

barrierl Reacts in pores and capillaries to create a

hydrophobic surface which repels waterl May be applied to new, cured concrete or

old concretel Excellent alkali resistancel Suitable for use over dry concretel Full protection in one treatmentl Easily diluted with potable water on the job

site. Diluted material must be used within 3hours

l Provides a low cost protection system thatcan extend the life of a structure

l Protects reinforcing steel against thecorrosive effects of surface chlorides andsurface moisture

l Renders new concrete virtually free ofsurface scaling

l Decreases the surface absorption of waterl Retards deterioration of existing, distressed

structures

DIRECTIONS FOR USESurface Preparation:New Concrete - Surface should be well cured (28days minimum) using water, wet burlap, polytheneor curing membrane. Where a curing membrane isrequired or desired for curing, only KUREZ DR dis-sipating resin curing compound is permitted. WhenKUREZ DR is used, a high pressure water blastor clean-up with an aggressive scrubber is requiredat 45 days or longer after application of KUREZDR. Surfaces must be free of all dirt and debris.All joint sealants and caulks should be in placebefore applying EUCO-GUARD VOX. The concretesurface must be dry with no darkening due tomoisture.Old Concrete - Remove all foreign substancesthat could prevent absorption-dirt, dust, tar, oil,etc. Pressure wash with water and cleaners whereappropriate. Membranes of any kind must beremoved. The concrete surface must be dry.Mixing - EUCO-GUARD VOX is a single compo-nent material which requires no pre-blending priorto dilution Select the proper dilution required forthe particular concentration desired and add theappropriate amount of water to EUCO-GUARDVOX. Blend for 1-2 minutes and the material isready for use. Note: The diluted material must beused with three (3) hours or the product’s effec-tiveness will be significantly reduced.Placement - EUCO-GUARD VOX must be job sitediluted and mixed with potable water. Gentleagitation is all that is required for thorough andcomplete mixing. To apply the diluted sealer toconcrete, use a pump-up or airless sprayer for best

rresults, alternatively a short nap roller or lambswool applicator may be used.Horizontal Surfaces - Flood surface using lowpressure sprayer, roller, brush or broom. Broom orsqueegee material around for even distribution. Letthe surface absorb the EUCO-GUARD VOXsolution and follow immediately with a secondapplication (if required) before the surface dries.Redistribute any puddles or free-standing EUCO-GUARD VOX.Vertical Surfaces - Apply by spray, roller or brushin two applications from the bottom up. Be sure toapply “wet-on-wet” as described for horizontalsurfaces.

CLEAN-UPUse soap and water to clean tools and equipment.

PRECAUTIONS / LIMITATIONSl Flash Point (21°C)l Do not dilute EUCO-GUARD VOX with

solvents or thinners.l Protect metal, glass and other surfaces

from oversprayl Do not use over saturated surfaces or

curing membranes.l Protect containers from direct sunlightl Heavy application rates may cause stainingl Diluted material must be applied within three

hours
