Preparing Roof for Shingle Shield
Application.
Surface preparation before applying a sealer to the roof is extremely important. Ensure that the roof is
free of active organic growth and or stains from mold or mildew on the shingles. The roof should be
structurally sound and free of loose or deteriorated shingles. All damaged areas should be repaired prior
to application. Repair or fill leaking areas with appropriate roof caulk or sealant. The roof should be
cleaned by a professional roof cleaning contractor to prevent further deterioration of the roof.
Ensure that there is no other water repellant treatment on the roof to provide best adhesion of the
product. Always test the product on the surface to be treated in an inconspicuous area to ensure proper
adherence and satisfactory appearance.
When to Apply Shingle Shield™ to your
Roof
When you apply sealer is important as well. Here are some guidelines:
• Shingle Shield must be applied under dry conditions. Applying to damp substrates could cause
haziness or loss of adhesion.
• Air temperatures should be above 50°F and below 85°F during sealer application. It is best to
perform the application in the morning hours due to the heat of the shingle. Heat directly impacts
the workability of the sealer. The hotter it is the faster it will dry on the shingle.
• Do not apply Shingle Shield Sealer when rain is forecasted within 24 hours.
How to Apply Shingle Shield™
Using the right tools is critical to achieving the best coverage rate and sealer thickness for optimal
performance. The most common method of applying the sealer is using a pump-up sprayer and roller for
back rolling when necessary. Review the Shingle Shield Technical Data Sheet and follow the Directions for
Use. It will include in more detail the surface preparation requirements, mixing of product, placement,
coverage, curing and clean up. Below is recommended application techniques to achieve best results.
1. Begin the application from the low side of the roof and work your way up. This helps eliminate
any streaking from excess runoff if it occurs.
2. Ensure that the pump-up sprayer maintains proper pressure to produce a consistent, even
amount of product on to the shingles. Avoid using sprayers that drip or cause splatter.
3. Maintain tip about 8 to 10 inches from the surface being treated (more or less depending on the
type of sprayer) and apply with steady, even strokes in a manageable area.
4. Continue this up until you reach a good break point and then begin again at the low side working
each section up against the previous wet area. Continue this until entire roof is covered.
5. Allow to dry, (minimum 30 min.) and apply second coat thin coat in a perpendicular or diagonal
pattern to the first coat. This will ensure the coverage in areas that may be missed or to thin.
Always strive achieve the recommended maximum coverage. The typical coverage rate is 250 to 300
square feet per gallon, depending on the porosity and condition of the shingles.
