A712 Polyester Spray Filler Set (1,08l)

PPG P.E. Spray Polyester Spray Filler A715

PPG P.E. Spray Polyester Spray Filler A715 is a light grey, 2-component polyester spray filler developed for the repair of large surfaces with extensive defects and irregularities. It is an ideal solution where conventional knifing stoppers would be less practical and more time-consuming.

The product is quick drying, easy to apply and provides high film build, making it highly effective for professional body repair work. After sanding, it can be overcoated with a suitable PPG 2K primer or surfacer before the topcoat is applied.

A715 can be used on a variety of properly prepared substrates, making it easy to integrate into professional refinishing systems. Its smooth application, fast workflow and good sanding characteristics make it especially useful for larger repair areas.

It is designed for workshops looking for a reliable, high-build polyester spray filler that helps prepare damaged surfaces efficiently for the next priming and refinishing steps.
