Polyester roller with thermo-fused 18mm long pile fabric. Knitted polyester is a high absorbency fabric, ideal for applying masonry, emulsions and all other water based paints onto semi rough interior or exterior surfaces. The Thermo-fusion manufacturing process bonds the fabric to the inner plastic core using a heat process giving the roller far greater longevity. Wash before use, the roller is 15 Inches wide with a 1.75 inch diameter core with end caps and is compatible with all 15 Inch double arm paint roller frames, and adjustable frames available on this site.
