The FIBER POLYESTER PUTTY is a two-component product formulated with unsaturated polyester resins, added with inert mineral fillers and reinforced with glass fibers.

Thanks to the use of high quality raw materials, FIBER POLYESTER PUTTY has exceptional anchoring, spreadability, flexibility, finish and excellent sanding quality. It does not cause lowering of thickness. It allows a finish and grouting without micro-holes and porosity. The addition of glass fibers determines an excellent filling power, making it suitable in cases of major cracks.

The product has excellent adhesion to steel, galvanized and aluminum surfaces. It can also be used on wood, concrete and more.
Immediately before use, the FIBER POLYESTER PUTTY is added with about 2% of a red paste benzoyl peroxide-based catalyst.
