WEATHER REQUIREMENTS FOR APPLICATION

A.

Application Acrylic Roof Coating Materials, including Acrylic Rust Inhibitive Metal Primer must be performed at 50 °F (10 °C) and rising. Temperatures must remain above 50 °F (10 °) for both application and cure time. Cure time will vary, depending on weather conditions. Low temperatures and high humidity will prolong cure time required.

B.

Do not begin work if rain is expected within twenty-four (24) hours of application. Do not apply if weather does not permit four to six (4 to 6) hours dry time prior to rain, fog or temperatures falling below 50 °F (10 °C).

3.02

SUBSTRATE PREPARATION

A.

It is the contractor’s responsibility to ensure that the substrate (roof surface to be coated) is adequately prepared to receive the Elastomeric Roof Coating System

B.

Holes, splits and openings in the metal roof must be repaired prior to application of the Elastomeric Roof Coating System.

1.

Holes less than or equal to (6.4 mm) in diameter can be patched using Acrylic Patching Cement and/or Elastomeric Seam Tape.

C.

New metal must be installed on all deteriorated metal panels with dents, holes or splits greater than 1/4" (6.4 mm) in any dimension.

1.

When a panel has deteriorated in the center but is still sound at the edges, it can be covered by a new panel without removing the damaged section.

2.

The new panel must be completely secured in the side laps with the screws of the proper type and size and taped at both ends.

D.

New metal must weather a minimum of six (6) months or be cleaned to remove residual oil. Residue can be removed using an environmentally safe cleaner.

E.

Replace loose or missing fasteners with oversized fasteners.

F.

Loose panels must be reattached using the appropriate fasteners to ensure panels are pulled together flush.

G.

Remove existing sealing materials (i.e., bituminous mastic, calk type sealant materials, etc.).

H.

Substrates must be clean and dry with no oils, grease, moisture or loose debris. Power washing is recommended.

I.

Treat all areas of corrosion with Rust Inhibitive Metal Primer or Acrylic Rust Inhibitive Metal Primer prior to applying repair products and coating.

J.

When Elastomeric Seam Tape is used, it is recommended that the installed tape be coated with Elastomeric Coating the same day as installation.

K.

Seal end laps with Elastomeric Seam Tape or three-coursed with Polyester Fabric and Acrylic Patching Cement.

L.

Side laps (vertical seams) must be sealed. Note: It is not necessary to seal vertical seams on standing seam roofs.

M. Install Elastomeric Seam Tape on all breaks in metal at corrugations

N.

On standing seam roofs, metal closures must be sealed with Acrylic Patching Cement.

O.

Caulk all reglets and termination bars.

P.

Corrective measures must be taken in areas where water ponds for more than forty-eight (48) hours. The inclusion of crickets or other remediation measures to remove low spots must be completed prior to coating application.

3.03

ELASTOMERIC ROOF COATING APPLICATION

A.

Inspect the roof to ensure that preparatory work has been properly completed and all substrate problem areas have been corrected.

B.

IMPORTANT: Allow for complete coverage by multiplying the total square feet of the area to be coated by a minimum of 1.15. The extra material will compensate for the additional surface area of corrugation and irregular metal surfaces, and will insure that adequate coating is on hand to complete the job.

C.

Apply a base coat of Elastomeric Roof Coating that is a different color than the surface coating to be used (Gray base coat is recommended, any color can be used).

D.

Base coat may be applied with airless sprayer, brush, or roller.

E.

Allow base coat to dry a minimum of twenty-four (24) hours before applying top coat.

F.

Inspect base coat prior to application of top coat. Confirm proper adhesion and that surface is clean.

G.

Provide finish coat in accordance with manufacturer’s application guide relative to current condition.

H.

All work to secure/maintain the manufacturer’s warranty must be completed using materials from that manufacturer.

I.

Inspect the completed application for uncoated areas, loose panels, gaps, holes, and joints that have been improperly taped.

J.

Correct any defects.
