Acrylic

Completed liquid coating jobAn ideal coating for many types of roofing materials include metal roofing panels, Acrylic roof coatings offer pleasing aesthetics, high reflectivity and good resistance to chemical attack. In addition, Acrylic roofing products provide significant savings in installation costs. When combined with the proper primers, adhesion of acrylic coatings can increase by as much as a factor of six, providing better long-term performance normally not found in roof coatings. In addition, when using an acrylic coating, the life for the protected substrate may be extended significantly. Not only can Acrylic fluid applied roofing be used for new installations, but also as part of a maintenance program adding life to existing single-ply membranes. Acrylic coatings dry to a monolithic coating that resists ozone, ultraviolet and general weathering, as well as heat and cold. Acrylic coatings are available in many colors and are a great choice for extending the lifetime of metal roofing materials. Roofed Right America typically recommends the application of an additional clear coating of acrylic fluid applied roofing to protect the colored coating: this helps to protect the coating from some of the extreme weather conditions in America's harshest climates!

Before and after shot using acrylic liquid roofing

Acrylic roof systems are designed to permanently waterproof most new or existing roofs with positive drainage, including roofs with low slopes and complicated flashings. The system consists of two principal components: a premium elastomeric liquid acrylic coating and a polyester reinforcing fabric. The fabric is embedded between multiple layers of the coating to create a seamless, reinforced flexible membrane that can last indefinitely with minimal maintenance. Flashings are simply painted in place and become an integral part of the membrane. Features include: suitable for any climate - remains flexible in arctic cold and will not crack or dry out in desert heat; unaffected by ultraviolet radiation resulting from long-term sun exposure; resistant to ozone, acid rain, and most other air pollution environmentally friendly - water-base coatings contain no toxic dispersants or tints; ideal for roofs used for rainwater collection; safety precautions for applicators are same as for water-base house paints bonds to almost anything - suitable substrates include asphalt, wood, metal, concrete, and rigid foam insulation boards durable in colors - architectural colors such as reds, greens, and grays match traditional metal roofs; white keeps buildings significantly cooler in the summer, saves energy, and minimizes urban heat-island effect.

Sun resistant acrylic liquid coatingAcrylic roof systems can be applied over hot-applied asphalts, cold-applied asphalts, asphalt composite sheets, metals, plywood, wood composite sheets, concrete, rigid foam, spray-applied foam, fiberglass, and many other substrates. We do not recommend coating board sheathing, tongue and groove decking, shingled roofs, and many plastics. The substrate must be firm and mechanically sound with no loose material or trapped water. Old asphalt roofs with extensive deep fissures and large bubbles should be stripped and the underlying roof deck should be re-sheathed. Acrylic is recommended for use on well-drained roofs with at least 1/8" per 12" slope and should not be used on roofs subject to long-term ponding of water. However, small puddles that evaporate within a day in the summer are generally not a problem; neither is winter snowfall that can remain for many weeks such as what we get in the Northern America roofing areas. The roof must be fully exposed so that it can dry rapidly after rainfall: it cannot be covered with wood decks, tile pavers, outdoor carpets, soil, or other coverings that can trap water. For the same reason, heat pumps, solar collectors, and other rooftop equipment should be elevated on curbs or other supports. To prevent mechanical damage, roof furniture should not have pointed legs. For best results, Roofed Right America attempts to apply acrylic roofs in warm, dry weather. However, application temperatures can be as low as 45° if the roof receives direct sunshine, the humidity is low, and it will not rain or freeze within 48 hours.

Maintenance and Longevity

White acrylic coatingMinor damage to acrylic roofs can be quickly repaired by cleaning the problem area and painting a few coats of acrylic. More severe damage is only slightly more difficult since it is necessary to first embed reinforcing fabric. Since acrylic roofs typically lose one to two mils of thickness each year by weathering, or the equivalent of a full coat every five to ten years, they must be pressure-washed and re-coated every five to ten years to prevent long-term loss of membrane thickness. Determine the minimum number of gallons required for maintenance by dividing the roof area in square feet by 80. If periodic re-coating will be difficult, double the gallons in the initial top coat to significantly prolong the re-coat interval.
