Technical data:
100 parts by weight TOPSTOP polyester filler, 2 parts by weight U-POL hardener for polyester filler.
The exact mixing ratio is not critical, although over or under catalysation may affect the gel time.
Do not greatly over catalyse the paste as this will not significantly speed up the gel time and could lead to bleed through and bleaching problems when over-painting later.
Staining may also occur where too little hardener is used.
Over Painting: Ideally a full system is recommended including primer.
