DESCRIPTION

CERTI-VEX GUARD CLEAR AIMM is a clear proprietary one step penetrating water repellent cure and seal that can be applied to new or existing concrete. It immediately penetrates the pores and capillaries of the concrete reacting with the alkali and moisture to form a hydrophobic gel in the pores and a water retentive film on the surface. This membrane, which meets ASTM curing requirements and the Chloride Ion Penetration requirements of NCHRP 244 forms a film that restricts moisture loss allowing concrete to reach maximum hardness and reduces staining, chloride migration, stops intrusion of water, salts, deicer chemicals and acids that can result in costly damage to concrete and masonry. This innovative one-step product eliminates the costly removal of curing compounds and time consuming water curing and leaves the surface cured and water repellent in one application. The final film has excellent moisture vapor transmission rates while excluding water and chloride ion penetration

BENEFITS

• An effective chloride screen
• Cures fresh concrete
• Vexcon breathable technology
• Deep penetration for maximum protection
• Especially suitable for alkaline concrete surfaces. Prolongs the surface life and prevents damage from within by maintaining vapor permeability of concrete
• Quick formation of surface repellency and chemical resistance
• Enhances surface appearance providing greater stain and oil resistance
• Non-yellowing
• Available in three gloss levels

RECOMMENDED FOR

Infrastructure, transportation, commercial and residential applications and any new and existing concrete that requires the long term protection of a water repellent sealer and a high performance stain resistant protective coating. It may be used as a water and stain repellent on vertical surfaces, on cast in place and pre-cast concrete or concrete block.

APPLICATION NOTES

• Prior to application a test area must be performed to determine proper application rate, techniques and required surface preparation.
• Application of Certi-Vex Guard Clear AIM may be done with a short 1/4" nap roller, brush or low-pressure industrial sprayer with neoprene fitting.
• Use a roller pan to take off excess product. Do not dip and roll or pour and spread.
• The product is supplied ready to use, do not dilute.
• Do not apply over free standing water.
• Application to damp surfaces is acceptable.

SURFACE PREPARATION

• The surface must be properly cleaned. Use one of Vexcon’s surface preparation and cleaning products to properly clean the surface prior to application.
• The surface must be properly repaired and structurally sound. Use a Vexcon repair mortar to correct any surface defects.
• Large cracks should be repaired using PowerCoat Epoxy Flexible Joint Sealant
• All caulking, patching and joint sealants should be installed in accordance with ACI standard specifications.

APPLICATION VERTICAL

• Begin application from the highest point; top to bottom.
• Roll or spray sufficient product to completely absorb and cover the surface.
• Succeeding passes must lap the previous run down. Do not over apply.
• Do not allow excess product to build on surface. Coverage depends on porosity.
• Check dried area for absorption and apply a second coat if necessary. For best coverage, apply the second coat perpendicular/90° to the first coat.

CURING AND SEALING NEW CONCRETE

• Apply in a single saturating application with sufficient material applied so that the surface remains wet for a few minutes before penetration.
• Surface residues, pools and puddles should be evened out until they completely penetrate into the surface.
• Remove efflorescence and laitance with Certi-Vex Etch & Efflorescence Remover.
• Apply Certi-Vex Guard Clear AIM three hours after the concrete has received final finishing and all gauging water has been absorbed. See Coverage Section for first coat application rate.

SHORT SPECIFICATION

[03 35 00] [03 39 00] [07 19 13] [09 96 00]: Basis of design, Low VOC compliant, clear silane/acrylic curing and sealing compound, water and stain repellent. Conforming to ASTM C-1315 type 1 Class A and NCHRP 244 series IV as manufactured by Vexcon Chemicals.

SEALING EXISTING CONCRETE

• Apply in a single saturating application with sufficient material applied so that the surface remains wet for a few minutes before penetration.
• Surface residues, pools and puddles should be evened out until they completely penetrate into the surface.
• To determine that the concrete is penetrable perform a water absorbency test by applying water to a representative portion of the prepared concrete floor. A properly prepared surface when dry will immediately absorb clean water without any surface beading effects.
• If required use Certi-Vex Etch & Efflorescence Remover to improve penetration.
• The concrete should be coated at coverage rate described below and allowed to completely penetrate the surface with no puddles, ponding or wet spots.
• If a liquid membrane curing compound has been used to cure the concrete, the surface can be water blasted to remove the coating and any dirt, dust, contaminates or use Certi-Vex Concrete Stripper to remove old sealers, grease, dirt and curing compounds. If the concrete

SECOND COAT

• A second coat is recommended if the initial first coat is damaged or a higher gloss protective top coat is desired.
• Before applying a second coat, the concrete surface should be cleaned free of dust, surface dirt and contaminants.
• Concrete that has become heavily contaminated with surface dirt, tire marks, oil, etc., during construction may require thorough cleaning for best performance of the second coat. See Coverage Section

SPECIAL NOTES
