DESCRIPTION

POWERSEAL 40 is a premium high performance breathable, efficient water base clear penetrating water repellent sealer that deeply penetrates into new (14 day minimum) or existing concrete and masonry surfaces. Surfaces treated with PowerSeal 40 have a totally natural appearance. PowerSeal 40 stops the intrusion of water, salts, deicer chemicals, and acid rain, which often result in efflorescence, mildew growth, corrosion, scaling, spalling, surface erosion, and other costly damage to hard surfaces. PowerSeal 40 penetrates into the pores and capillaries of the cement based materials reacting with the moisture and chemicals in the substrate, polymerizing and sealing the pores, which prevents water, chemical and chloride ion penetration. PowerSeal is specially formulated with a reduced evaporation rate so more of the active ingredients react with the substrate rather than evaporate with the solvent or water as with similar products. Material efficiency is increased, making PowerSeal more effective than competitive products

BENEFITS

• Extends the life of concrete and masonry surfaces
• Best long term protection against salt corrosion, deicing chemicals, mildew, water, wind driven rain, airborne contaminants, surface spalling from freeze/thaw cycles, and other severe weather conditions
• Reduces corrosion of rebar and surface erosion in reinforced concrete
• An effective chloride screen
• Prolongs the surface life and prevents damage from within by maintaining vapor permeability of concrete
• Superior water repellency
• Can be applied to damp surfaces
• Suitable for alkaline concrete surfaces
• Water base - safer to use - low odor
• Does not alter natural surface texture or appearance
• Keeps substrate cleaner

EXCLUSIVE PROTECTIVE COLLOID EMULSION

PowerSeal water repellents are produced with Vexcon's proprietary protective colloid emulsion technology. This technology prevents premature hydrolysis of the silane with the water used as a carrier in the emulsion. Premature hydrolysis is a process that reduces the effectiveness of water repellents.

PRE-INSTALLATION NOTES

• A test application is necessary on each surface to be treated to ensure compatibility and desired water repellency. Test areas are also useful in determining final application rate and procedures.
• If the material in the test area does not fully penetrate due to coatings or inadequately cleaned surface, use one of Vexcon’s cleaners and stain removal products to properly clean the surface prior to application.
• If a tacky residue remains after 24 hrs, the application rate must be modified. Material which remains tacky on the surface can usually be removed by washing with water or a vinegar solution.
• Tests should be applied using the same equipment and techniques planned for job application.
• Overspray can be removed with Certi-Vex? Equipment Cleaner before the solution has dried. Protect non-porous surfaces

SURFACE PREPARATION

• All caulking, patching, and joint sealants should be installed and fully cured prior to application. Concrete should be properly cured; see Curing Recommendations section.
• All surfaces must be cleaned free of dust, dirt, surface materials, previous coatings, and contaminants.
• New concrete normally does not require etching. However, slick trowel finished concrete that has become heavily contaminated with surface dirt, tire marks, oil, etc., during construction may require thorough cleaning and a mild etch using StarSeal EF Safe Etch.
• Older concrete surfaces should be power washed with high-pressure water and StarSeal Brick & Masonry Cleaner to assure removal of surface dirt, oil and other contaminants; use StarSeal EF Stripper to remove coatings, adhesives and floor waxes.
• To determine that the concrete is penetrable, perform a water absorbency test by applying water to a representative portion of the prepared surface. A properly prepared surface when dry will immediately absorb clean water without any surface beading effects.

CURING RECOMMENDATIONS

1. Concrete can be cured with Certi-Vex Envio Cure, an emulsion resin cure, which will dissipate. Allow to dissipate or remove with StarSeal EF Stripper.
2. Wet Cure

SHORT SPECIFICATION

PACKAGING

PowerSeal 40 is available in 55 gallon drums and 5 gallon pails. Contact Vexcon directly to discuss your customized packaging requirements

APPLICATION

• PowerSeal 40 should not be diluted or altered, see Coverage Rates.
• Apply with low-pressure (20-PSI) airless industrial spray equipment. Sprayer should be fitted with solvent resistant hoses and gaskets.
• If using brushes or rollers, care should be taken to ensure that enough solution is applied.
• Treated surfaces should be protected from rain and foot traffic for 4-6 hours following application.
• Protect from vehicular traffic up to 24 hrs. or until the surface is dry.
• Allow 5-7 days for the product to fully react before evaluation

HORIZONTAL SURFACES

• Apply in a single saturating application with sufficient material applied so the surface remains wet for a few minutes before penetration into the surface.
• Surface residues, pools and puddles should be broomed or brushed out until they completely penetrate into the surface

VERTICAL SURFACES

• PowerSeal 40 should be applied and absorbed on the substrate to the specified coverage rate.
• In the case of extremely dense, mirror finish architectural concrete and similar surfaces, it may be necessary to restrict the amount of material by first applying a light mist coat by the procedure listed below in order to prevent surface darkening.
• Allow the mist coat to penetrate the masonry surface (approximately 3-5 minutes) and apply in the same saturation manner.
• Apply PowerSeal 40 in a flooding application, from the bottom up with sufficient material applied to provide a 6" to 8" run down below the contact point of the new spray pattern with the surface
