Applications

Ethylene propylene diene monomer (EPDM) is a type of synthetic rubber commonly used for single-ply roofing membranes. As they age, EPDM roofs erode, shrink, and experience seam failure as they age, which can lead to leaks and roof failure. Metacrylics coatings are proven to provide ample protection against weathering and water infiltration, leading to better overall building efficiency.

Single-ply TPO membranes can often be difficult for coatings to adhere to. When applied to a suitable cleaned, weathered TPO roof, Metacrylics TPO Primer and Metacrylics coatings provide optimal adhesion. TPO roofs with leaking or deterioration issues due to ponding conditions and seam failures should be coated with Metacrylics. Metacrylics coatings withstand ponding conditions and resist debris, protecting the existing membrane from water infiltration.

Metacrylics coatings provide protection over failing or aged built-up roofing (BUR). BUR absorbs and holds heat, advancing the aging and weathering of the roof and eventually causing leaks and failure. Coating BUR with Metacrylics increases the efficiency of the building by reflecting hear and damaging UV rays.

Metacrylics coatings also create a monolithic membrane, protecting the existing roof from damaging weather and moisture. Metacrylics coatings withstand ponding conditions and resist debris, protecting the existing membrane from water infiltration. By using Metacrylics to coat the existing roof, building owners and managers are able to avoid costly tear-offs and re-roofs.

Metacrylics coatings provide protection over aging or failing tar and gravel roofs. As tar and gravel roofs age, the gravel loosens and leaves the membrane vulnerable to UV rays and weathering. Tar and gravel roofs also absorb and hold heat, increasing roof and internal temperatures, causing increased energy and utility costs. Metacrylics coatings provide protection by reflecting heat and sunlight, leading to a more energy efficient building. Metacrylics coatings also withstand ponding conditions and resist debris, protecting the existing membrane from water infiltration. By coating the existing tar and gravel roof with Metacrylics, building owners and property managers are able to avoid costly tear-offs and re-roofs.

Standing seam metal roofing systems utilize interlocking panels attached by concealed fasteners. Although standing seam metal roofs are typically much more durable compared to traditional roofing materials, they’re still susceptible to weathering and wear and tear as they age. Metacrylics coatings provide additional protection by preventing rusting and damage from harsh environmental conditions, extending the life of the standing seam metal roof. Coating a standing seam metal roof with Metacrylics creates better insulation from heat, water infiltration, and external noise.

Metacrylics coatings provide protection over failing or aging metal roofs. As exterior temperatures fluctuate, metal roofs expand and contract and experience movement that can wear down sealants protecting the roof from leaks. Coating metal roofs with Metacrylics reflective coatings lower roof temperatures by reflecting UV rays and sunlight and are formulated to handle the movement of the roof without failing. Metacrylics coatings protect metal roofs from rust damage and are a more cost effective repair than a complete re-roof.

Metacrylics coatings protect new construction plywood from weathering that can degrade the roof and cause leaks. Metacrylics coatings over new construction plywood reflect heat and UV rays, lowering roof and interior temperatures, potentially lowering utility costs. Class A Fire Rating over plywood requires either DensDeck® or Atlas FR Slipsheet.

Metacrylics Roof & Tile Sealer protects and restores tile roofs. Aged or failing tile roofs absorb moisture, creating extra weight on the structure. Metacrylics Roof & Tile Primer penetrates and strengthens the surface. Metacrylics Roof & Tile Sealer creates a seal on the surface that blocks moisture from the tile. As a result, it eliminates the extra weight load. Roof & Tile Sealer is available in 36 colors.

Gutters

1. Thoroughly pressure wash gutters at a minimum of 3,000 PSI. Rusted areas must be replaced with new gutters.
2. Apply primer to gutters.
3. 3-Course with GEL & FABRIC over all joints. Do not use PEEL & COAT on any gutters!

Parapets Coping (CAP)

1. Thoroughly wash or pressure wash parapet coping.
2. Prime coping. Any rusted areas must be primed with black primer instead of clear primer.
3. Apply 4” Metacrylics PEEL & COAT and GEL or CLEAR BASE, or 3-Course with GEL & FABRIC over the top of the coping (cap) joints.
4. Coat with additional BASE & WHITE topcoat.

Nosings, Edge Flashings, & Gravel Stops

1. Apply primer to all edge flashings. If new, wipe with vinegar or a suitable cleaning agent.
2. Apply 3-Course with 6”-9” FABRIC & GEL over the top of the edge flashing.
3. Apply the 3-Course 3” on horizontal flashing and 3” on the vertical flashing on the outside wall.

Wood Blocks

1. Lift and remove block.
2. Apply GEL or ACRYLIC BASE & WHITE coating to the area.
3. Allow to dry and replace block.
4. If damage to the roof occurs while removing block, 3-Course with GEL & FABRIC and replace block when dry.

Wood Sleepers (HVAC Supports)

1. Jack up the HVAC unit and remove sleeper.
2. Install Metacrylics one-ply or granulated slip sheet under the entire area of sleepers and HVAC.
3. When the system is cured, replace sleepers. Be sure that lags attaching HVAC to sleepers are not too long and will not penetrate the roof system.
4. If sleepers cannot be moved or lifted, they must be completely encapsulated. The area under HVAC should be coated with Metacrylics and reinforced with fabric.
