Caravan Repair with HBC System E Step by step

Caravan Repair with HBC System E – Step by step

1. Check the dent (there may not be any areas there are to high.) 
2. Knock down edges/kanter so the overgang/transition of the dent becomes slanting/skrå, about 45 degrees. 
3. Grind the damaged area until the paint is gone. You can use a wire brush. 
4. Clean the dent and the area were the copy is going to be taken. Clean with E-cleaner. 
5. Measure the dent on the plate/caravan. Check the fixed points several times. 
6. Fit the niveau rail by applying an appropriate layer of mouldmaker on the back of it. Make sure that the injection hole is in the centre of the damage. 
7. If it is upgrade: Check the fixed points and fit the niveau rail with vacuum.  
8. Fasten the vacuum tool. Fit the vacuum tool on top of the niveau rail. 
9. Check if there is space between the niveau rail and the vacuum tool. Check fixed points. 
10. Copy: Fill mouldmaker in the hole slowly to the edge. 2cm larger than the damaged spot. Pull up the mixing tip slowly to avoid air pocket/a hole. 
11. Take the vacuum tool of the plate/caravan. You can use a palette. The copy is done. Press out the air lightly.  
12. Forskyd/displace,place the vacuum tool/copy to the dent efter fixed points. Check the space between the niveau rail and the vacuum tool. 
13. Mix the støbemasse (E-filler and hardener.) ½ pipette, ½ HBC mixing jar at 20 degrees.  
14. Fill the injector. Make sure that there is no air in the injector. 
15. Cut of the prop/top of the copy. Important: Place the needle in the middle of the copy and inject the e-filler very carefully while at the same time twisting the injector/needle to avoid air in the cast. 
16. Remove the needle at the first sign of e-filler next to the mould. Carefully keep on filling while the needle is being removed, to fill the hole in the cast.  
17. If it needs more filling: Leave the needle in and fill the injector.  
18. The hardening time is 30 minutes at 20 degrees.  
19. Grind with the glass pen. 
20. Apply the Primer between the repair area and the plate.  
21. Spray carefully the area with primer and grind again. Avoid spraying too much into the middle of the repair.  
22. Regrind with the glass pen if necessary.  
23. Apply the right caravan colour. Warm up the area to 50 degrees to speed up the curing process.
24. Apply fade thinner in the mat area (in the rim zone). Bruges til at fjerne sprøjtestøv. The fade thinner dries in 10 minutes, so wait and see the result before applying more fade thinner.  
25. After a couple of hours you can polish if needed. 

Good advices:

  

- Clean the tools after use.

- The vacuum tools are going to be placed right after use to avoid damages on the gasket.

- Good light.

- You can use a palette or fishing line to get the copy/vacuum tool of.

- Avoid taking of the vacuum tool to fast, when you have made the copy.

- There may not be any air in the injector with e-filler.

- Mouldmaker: Leave the mixing tip on for next time. Change the mixing tip before you use it again.

- Painting with aerosol: Press or don’t. Remember to spray before use.

- Important:
Clean the plate on the caravan.
Clean the caravan tools in hot water.
