Benefits of technology
[0051]As the water soluble sealant penetrates into the paver, it bonds with the concrete capillary structure of the paver. The sealer dries before the internal moisture in the paver is completely wicked to the surface. Since the sealer dries prior to the internal moisture being wicked to the paver surface, the paver surface is protected from effervescence. After the sealer dries paver internal water moisture slowly evaporates through the “pores” in the dried sealer. The controlled viscosity of the custom developed sealer assures that the pavers are properly sealed with a minimum of calcium carbonate formation.
[0052]To deter the growth of mold, fungus and mildew, a water-soluble fungicide may be added
Problems solved by technology
Any moisture in the paver during application of the sealer or during the curing process will result in bubbling, that ruins the finish and visual appearance of the application.
Urethane sealers are typically not UV tolerant, hence are normally restricted to indoor applications.
Epoxy sealers are not tolerant to ultraviolet light, hence are not typically used for outdoor paver sealing applications and typically do not allow the paver to release moisture, hence may lead to premature sealer failure or paver structural failure over time.
Both Epoxy or Urethane sealer application can result in trapped moisture in the paver that may ultimately result in a loss of “sealer to paver surface bond” indicative of pealing or flaking failures.
Cure and seal acrylic resins are not well suited for fully cured co

Example
[0020]To appreciate the invention described herein, one must examine the manner in which paver sealer chemicals are typically applied today.
[0021]Normally, pavers FIG. 1 (1) are set in a prepared base foundation suitable for the local soil, climatic and geographical conditions. In frost free areas this base foundation may only consist of a several inches of aggregate material base FIG. 1 (4), while in northern parts of the country exposed to severe frost the aggregate material base FIG. 1, (4), may be many inches thick and will probably contain drainage components to reduce the likelihood of frost heaves. Typically, an aggregate base FIG. 1, (4) or asphalt treated based is topped with bedding sand base FIG. 1 (3). Individual pavers FIG. 1, (1) are set in the bedding sand material FIG. 1 (3) and spaced to produce a small gap, typically ¼ inch, which is filled with sand or an equivalent material as shown in FIG. 1, (2), the sand joint. The inter-paver joints FIG. 1, (2) are usually fi...

Abstract
An application process for an environmentally friendly water soluble acrylic emulsion paver sealant. The process described herein supports environmentally friendly application, a cost effective application that can be completed in 1 day without the normal “drying time” of other sealants and other application processes. The process stated herein is not sensitive to moisture as with other sealants. The sealant can be applied under wet or dry conditions and provides deep sealing with the application of a flood coat. The ability to apply a flood coat of sealant under wet or dry conditions speeds the application of the sealant and results in the elimination of the normally necessary “drying time” required in the application of other sealants. Furthermore, the application of a flood coat under wet conditions minimizes the formation of effervescence.
The described process herein further supports a host of sealant additives to improve the environmental characteristics of the sealant. Anti-algaecide and anti-fungicide additives retard the growth of mold, mildew and moss on the pavers. Another sealant additive retards the propensity for tire marking when pavers are used in areas of vehicular traffic.
The process further supports a surface enhancement that results in improved surface luster, making the pavers more visually appealing.
The unique and novel process has been developed in conjunction with a specially formulated water soluble acrylic emulsion sealant compatible with this wet application process that provides paver sealing, sand joint stabilization, and visual surface enhancement.
Description
BACKGROUND[0001]1. Filed of the Invention[0002]It has long been known that patio, sidewalk and driveway pavers were subject to physical and visual degradation and ultimate failure over time due to various environmental factors. Environmental factors such as sunlight, rain, snow, freezing and biological factors such as fungus, moss, mold and mildew over time can degrade the structure and physical appearance of pavers. Numerous techniques have been developed over the years to protect pavers from such adverse attacks. The need for paver protection is increasing, especially in recent years. Between 1998 and 2004 concrete paver installed square footage has grown from 251 million square feet to 630 million square feet.[0003]This patent application describes a method for the application of a specific water soluble and environmentally friendly acrylic emulsion sealant using an application process that speeds application, reduces the release of Volatile Organic Components (VOC's), enhances s...
