FB-180 series polyester km-mesh is a stitchbonded material that is ideally suited for use with RV Roof Magic coatings. The parallel fiber structure allows RV Roof Magic to quickly wet-out and totally saturate. These properties ensure a true monolithic membrane which remains intact even under thermal shock conditions.


  • Reinforcement of seams, cracks and penetrations on:
    • Various roofing surfaces
    • Concrete, stucco and brick
    • Wood joints and cracks

RV Roof Magic FB-180 provides high tensile strength with good elongation for excellent thermal stress force properties. When used with RV Roof Magic, they provide flexible, reinforced repairs.

RV Roof Magic FB-180 are soft flexible polyesters that will readily conform to corrugated metal and many other irregular surfaces. This makes them easier to handle and apply properly than other products.

RV Roof Magic FB-180 polyester km-mesh is compatible with both solvent-based and water-based coatings.

Our polyester mesh is a stitch-bonded material that is ideally suited for use with RV Roof Magic coatings. It is used in conjunction with our Seam Tight. Along any seams you will paint an 8 inch long vertical line down the seam and then roll out the polyester mesh and embed the fabric into the wet SeamTight. Let dry and apply another coating of the SeamTight over the exposed fabric and let dry. Now you are ready to apply the RvRoofMagic to the entire roof. This process ensures that the fabric is encapsulated into the SeamTight allowing your seam to never come apart.
