OPTIMAL STRENGTH AND SEAM SUPPORT
Ames Poly-300 Roof Fabric is a strong, conforming polyester reinforcement fabric perfectly suited for use with Ames roof coatings over flat or low pitch roofs and roof decks. It provides additional tensile strength and elongation to help resist tears and punctures as part of the Ames Roof Coating System Membrane. It is a soft material and easy to use as it conforms to the roof and saturates easily in the embedding process. The result is a tightly bonded, waterproof, and seamless protective membrane over the roof surface. Poly-300 is used in leveling low spots at ponding areas, large spot repairs, and for full reinforcement across the roof system when specified.
PREPARATION & SEAM REINFORCEMENT
Prepare the roof or roof deck removing dirt, moss and other debris by carefully power washing. Let dry thoroughly and make any needed repairs. Prime the roof surface and apply 4-inch wide Ames Poly-Bridge Fabric and Ames Elasto-Barrier or Ames Blue Max over joints, seams, flashing, and transitions on the existing roof.
- Utility Knife
- Soft-Bristled Push Broom or Long Handled Roller with Cover
- Ames’ Poly-Bridge 4” x 100’ Reinforcement Fabric for joints, seams, flashing, and transitions.
- Ames’ Blue Max Caulk for smoothing transitions at penetrations, curbs, sharp angles, embeds, etc.
- Ames’ Elasto-Barrier or Ames’ Blue Max adhesive base coats.
36” WIDTH FABRIC APPLICATION PROCESS
Step One: Determine your starting point on the roof and intended direction of travel across the roof. Pour or spray apply the selected Ames Roof Coating in a path slightly wider than the roof fabric being used. The material can be leveled out with a paint roller, or roofing squeegee.
Step Two: While coating is wet, place fabric over the coating by unrolling the fabric while avoiding folds and wrinkles. Keeping a slight tension on the roll of fabric in the direction of travel will assist you in keeping wrinkles out. As the fabric settles down onto the wet material roll out trapped air and excessive material with a paint roller. Avoid pressing down too hard with your paint roller during this process to avoid creating folds or wrinkles. Roll from the inside of the fabric toward the outside edge and in the direction the fabric was unrolled to avoid trapping air, creating wrinkles, or picking up edges of fabric with your wet roller. In the event sufficient material is not wicking up through the fabric to fully saturate the fabric; then add more material as you roll in the fabric and adjust up the amount of material you are spreading on the next course (row) of fabric. Now is an excellent time to pick up excess material left along the outside edge of the fabric line with your roller and roll it out onto the fabric surface as you go. If the underlying coating is drying out before you can get the fabric fully rolled in and saturated with the coating, then you need to reduce the active work area on the next course to maintain a wet surface or add manpower.
Step Three: Determine your overlap on the next course of fabric and apply your coating for the next pass accordingly. You can place pencil marks along the roof area, use a yard stick or mark a gauging stick to use as a guide while making your determination. As previously done on the first row of fabric, apply the wet material in a path slightly wider than the fabric while overlapping the previously installed fabric by at least 3 inches. Fully embed as instructed in Step Two repeating this process across the entire roof and allow to dry from 24 to 48 hours.
Step Four: After all courses of roof fabric have been installed and are sufficiently dry, a full sealing coat of the selected Ames Product is required to be applied at recommended rates to completely seal and fill any remaining pinholes in the fabric. After Step Four your fabric installation is complete and ready for succeeding coats of Ames Roof Coating for your specific roof.
