Drying

• 20°C : 15 - 20 min
• Pot life at 20°C : 3 - 4 min

Mixing Ratio:

• 100 parts by weight polyester filler, 3-4 parts by weight hardener for polyester filler.
• The exact mixing ratio is not critical, although over or under catalyzation 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. 
• Do not overdose! Excessive quantity of hardener can cause colour change on the topcoat.
