KM Coatings Prime Poly Mesh Stitchbonded Polyester Reinforcing Mesh, White, 4 in. to 40 in. x 300 ft. Rolls
KM Coatings Prime Poly Mesh is a stitchbonded polyester reinforcement used in cold process roofing with acrylic coatings. It combines high tensile strength with good elongation to accommodate thermal stress forces. Each sell unit is one white roll, available in 4 in., 6 in., 12 in., 20 in. and 40 in. widths by 300 ft.
Key Features:
- High strength: Stitchbonded polyester construction is among the strongest reinforcement materials available to the roofing industry.
- Thermal stress control: Good elongation properties provide excellent accommodation of thermal stress forces in the membrane.
- Acrylic compatible: Designed for use with acrylic coatings in cold process roofing systems.
- Seam reinforcement: Suitable for reinforcing seams, flashing details and the field of liquid-applied roof membranes.
- Multiple widths: Offered in 4 in., 6 in., 12 in., 20 in. and 40 in. widths to match different detailing needs.
- White fabric: Supplied in white, which helps the fabric read clearly under subsequent coating passes.

Coverage & How Much You Need:
One 300 ft. roll covers 300 linear feet at its nominal width, so a 40 in. roll yields roughly 100 sq. yd. of reinforcement per roll at full width. Size seams and full-field reinforcement separately, choosing narrower widths for seams and flashing and wider widths for field lapping.
Fit and Compatibility:
Intended for use with KM Coatings acrylic coatings and Primebase-type base coats in cold process, liquid-applied roofing assemblies. Sold as fabric only; base and top coats are purchased separately.
Frequently Asked Questions (FAQ):
Q: What is included in one order?
A: One roll of white stitchbonded polyester mesh in the selected width and length.
Q: Which widths should I use?
A: Narrow 4 in. to 12 in. rolls suit seams and flashing details, while 20 in. and 40 in. widths cover field reinforcement and larger patched areas.
Q: Does it work with any coating?
A: It is specified for use with acrylic coatings in cold process roofing; verify compatibility with your specific system before use.
Q: Why stitchbonded fabric?
A: Stitchbonding gives the mesh high strength while retaining elongation, so the reinforced membrane can flex with thermal movement.
Q: How do I size a job?
A: Multiply linear feet of area to be reinforced by the roll width, then add overlap at seams when estimating roll count.
Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose the narrowest width that fully bridges the detail you are reinforcing; oversized mesh creates extra lap waste. Embed the mesh fully wet into the base coat with a roller, then apply the top coat at the specified coverage before the base skins over. Keep laps to the manufacturer's specified overlap and avoid stretching the fabric, which can telegraph through the coating.
Wear gloves and eye protection when handling reinforcing mesh and coatings, and follow the coating manufacturer's SDS and job-site fall protection requirements.
