Why replace when you can Overlay?

Concrete Overlays date to the 1960s when chemical engineers from some of the larger, well-known chemical companies began to experiment with acrylic paint resins as modifiers for cement and sand mixes. The result was a thin cementitious topping material that would adhere to concrete surfaces and provide a newly resurfaced coating to restore the worn surface. Concrete overlays lacked the long-term performance characteristics of acrylic resins. Acrylic resins provided good UV resistance, but lacked long term water resistance and adhesion characteristics needed to provide a long term and permanent solution.

Polymer Overlays

Polymer cement overlays, consisting of a proprietary blend of Portland cements, and various polymer resins. The purpose of adding a polymer resin to the cement is to greatly increase the performance characteristics and versatility of conventional cements, mortars and concrete materials. Unlike conventional cement and concrete mixes, polymer cement overlays can be applied thinly or thickly without fear of delamination or product failure. In addition, polymer cement overlays are much more resistant to damage from salt, petrochemicals UV, harsh weather conditions and traffic wearing.Originally intended for use as a thin surface restoration material for concrete substrates, polymer cement overlays were introduced into the architectural concrete and commercial flooring industries in the early 80s, subsequently, its use in these industries has become standard. Polymer cement overlays are regarded as economical in providing long term, durable renovation without the need for costly and continuous repairs associated with deteriorating concrete surfaces.Polymer cement overlays are used for interior and exterior applications ranging from:

Concrete Resurfacing- Skim coat/broom finish

Redecoration and Renovation of existing substrate

Restoration- Restore and protect damaged, pitted, flaking and stained concrete back to the look of a new concrete surface.

Concrete regrading & leveling- Repair and level concrete surfaces that have settled.

Alter the appearance of existing concrete or wood substrates through applying "thin stamped" or "thin stained" overlays, creating new textures, colors and designs. For use on commercial or resident pool deck, this frequently takes the form of "splatter textures" or "knockdowns," in which polymer cement is applied to the existing concrete substrate in a moderately textured finish (average of 1/8” thickness) in various patterns. Often, the texture is knocked down with a trowel to slightly modify theappearance and feel of the finished application.

Stamped Overlays

Rubber imprinting tools (stamps) are impressed into thin pre-mixed concrete overlay material to create natural stone or brick textures. These rubber-imprinting tools are manufactured from molds created from authentic stone or wood. Release agents are used to help release the stamps from the concrete without sticking. Release agents come in either a liquid or powder form, and with a wide range of secondary color options.
