Flashing Grade™

Heavy Bodied, Flexible, Waterproof Flashing Compound

Flashing Grade™ is a trowellable or brushable waterborne paste with good adhesion characteristics. It dries to form a flexible and waterproof membrane ideal for flashing, seaming and crackfilling.

Uses

Sealoflex Flashing Grade™ is used:
• To form flashing around penetrations, air handling units, skylights and roof to wall junctions
• To seal vertical joints on metal roofs
• As a sealer for fasteners on metal roofs.

Advantages

Sealoflex Flashing Grade™ displays the following advantages:
• Easily applied with brush or trowel
• Excellent Ultraviolet resistance
• Flexible when cured
• Fast drying
• Water-based for easy cleanup
• Excellent adhesion to wood, metal, stucco, painted surfaces, concrete, brick and other surfaces
• Ultra Violet resistant
• Excellent filler over rough surfaces

Surface Preparation

Remove all oil and grease, grit and loose particles from the substrate. Prime where necessary. Refer to the Sealoflex Priming Chart.

Application

Apply Flashing Grade™ with a brush, putty knife, or trowel. Do not apply more than 1/8” thick. When applying multiple layers, ensure that the previous layer is fully cured. Over coating with Sealoflex Finish Coat™ or Sealcoat Elastic™ can commence once the Flashing Grade is thoroughly dry. To create flashings, use 6” wide Coraflex Jointing Fabric™ symmetrically across the change in plane such that the fabric is applied 3” up the wall or penetration and 3” onto the roof. Apply a generous coat of Flashing Grade™ through the fabric ensuring that the fabric is in full contact with the surfaces below. Allow to dry. Apply a 2nd generous coat to the area. Allow to dry.

Curing

Drying time will be approximately 2 hours, depending on weather conditions.

Cleaning

Clean all equipment and tools immediately with water. Dried Sealoflex Flashing Grade™ can be removed with Sealoflex Quickclean™ water-soluble solvent.

Important Notes

• Do not apply when precipitation is imminent
• Ensure that areas where Flashing Grade™ is applied are well drained and will not pond water
• Do not apply at temperatures below 40˚F
• Do not cover with stone chips, screeds, tiles or soil
