Product Q&A

Q:What are the main applications of this product?

It is designed as an underlayment for roof decks, walls, and floors, used beneath asphalt shingles, wood shakes, tiles, and other slope coverings.

Q:What are the installation requirements for the roof deck?

The deck must be clear of all debris and moisture. Installation should start from the bottom edge in horizontal layers, avoiding installation when wet.

Q:How should the felt be installed on different roof slopes?

For slopes up to 33%, use a double layer with 19-inch headlap. For slopes 33% or greater, use a single layer with 4-inch headlap.

Q:What fasteners and spacing are required?

Use minimum 12ga, 1-1/4 inch ring shank nails with 1-5/8 inch diameter tin caps. Spacing should be max 6 inches on center at laps and 12 inches in the field.

Q:How should wrinkles be handled during installation?

Avoid wrinkles during rolling. If formed, slice them, fasten flat to the deck, and seal the cuts with waterproofing cement.
