Technical Information Polyester Resin
presto Polyester Resin is an elastic, very reactive unsaturated polyester resin, which can be applied on nearly any surface, especially in combination with fibreglass tissue and fibreglass matt to brigde bigger holes, perforations from corrosions and damaged areas. Very good applicable on metal, wood and concrete, in the car sector, in the household, mould and model building, in the garden (spray-fiber manufactured ponds) and in other industrial sectors, for example for leaking conductions and ductwork, tanks, boats etc.
If you intend to paint afterwards, we recommend to apply presto Body Filler or presto Filler after the use of the resin.

Before use, carefully read and observe the warning texts on the label!
- The object you wish to repair should be de-rusted, clean, dry, fat-free and sanded.
- Cut the glassfibre tissue depending on size of damaged area, calculate a sufficient overlapping.
- Take the requested portion of putty compound out of the can and mix it well with the corresponding quantity of hardener, then go on as following:
- Brush some resin on the prepared surface and put the fibreglass material on this spot.
- Press it with the help of a brush evenly onto the repair spot, starting at the edge, then soak it again with polyester resin. The glassfibre may have no air inclusions.
- As last layer you should apply and soak glassfibre fleece as a suitable coat for subsequent repair work. It is possible to proceed with several layers.
- If you wish to lacquer the surface, we recommend to go on with prestolith plastic Body Filler or with prestoflex Fine Filler. The surface of the polyester resin remains sticky and thus works as optimal adhesion promoter. If desired, you can wash off this sticky surface with nitro thinner.
- Clean tools immediately after use, if necessary with a nitro thinner.
- Do not return mixed material into the can.
- After approx. 40 minutes the repaired spot can be drilled, sanded, sawed, rasped and painted.
