Metal Roof Slideshow

Read all label instructions before beginning. Always run a test patch first in an inconspicuous area, to ensure that proper adhesion and drying occurs and the product works to your satisfaction.

1. Surface Preparation
The roof must be dry. Remove loose dirt, flaking rust, and debris from the roof surface. Refasten any screws or nails that may have worked loose. Be sure surfaces are clean and dry before the coating application. Caulk all cracks greater than 1/8” wide with Blue Max trowel-grade coating and filler.

2. Seam Tape & Prime the Roof Surface
Prime with 1-3 coats until the roof surface is smooth and sealed. Maximum-Stretch or Iron Coat may be used to prime the roof, but with difficult surfaces such as rusty metal or oxidized aluminum, Ames' Super Primer is required to optimize adhesion to metal surfaces. Surfaces with joints, cracks, flashings, vents, parapet wall flashings or where two unlike surfaces come together, require Ames’ Peel & Stick Seam Tape (PS250, PS450, PS650) to provide some additional strength and reinforcement. For the best adhesion prime all metal surfaces with Super Primer before applying the seam tape. Where adhesion is in question always use Super Primer. Use the entire product. Let cure so that it's dry to the touch.

1. Peel off the backing	2. Line tape up with seam	3. Press firmly into place.

3. Pour it out and Paint it on
Apply coating as needed for a durable, hard shell, thermo-reflective surface.

Good: 1-3 coats of Maximum-Stretch or Iron Coat.

Better: 1 coat of Super Primer, top coat with Maximum-Stretch or Iron Coat.

Best: 1-2 coats of Super Primer: top with 3 coats of Maximum-Stretch, Iron Coat or similar Ames’ product.

Clean up, Storage, Disposal and Thinning
Clean up tools and small spills with water. Store unused product in its original can, tightly sealed at 45 to 85 degree F. Dispose of this product in accordance with state and federal and local requirements. Thin with water up to 10%.

Weather and Drying Guidelines
Best results when applied between 40 to 90 degrees F on warm dry surfaces. Apply when the streets are dry, the sun is in the sky and no inclement weather is forecast. Dries in 1-2 hours, depending on thickness of application and weather; cures in 24 hours. Low temperatures, high humidity and evening and morning dew will require increased drying/curing time.

Estimated Coverage
Standard product coverage on a smooth surface is 100 sq. ft. per gallon per coat (est. 10ml). More than one coat recommended. More coats equal longer life. Super Primer covers up to 500 to 1,000 square feet per five gallons when used as a coating.
