Important note 
This model is not made of Styrofoam™, and it is not possible to glue the material using white glue, polyurethane or 
epoxy; these adhesives only produce supercial joints, and simply break away under stress. Please be sure to use 
medium-viscosity cyano-acrylate glue exclusively, preferably Zacki ELAPOR® # 59 2727, which is optimised specically 
for ELAPOR® particle foam. If you se Zacki ELAPOR® there is usually no need for cyano ‘kicker’ or activator. However, 
if you wish to use a different adhesive which requires the use of activator, please note that these materials are injurious 
to health, and should always be applied in the open air. Take care when handling all cyano-acrylate adhesives, as they 
harden in seconds, so don’t get them on your ngers or other parts of the body. We strongly recommend the use of 
goggles to protect your eyes. Keep the adhesive out of the reach of children! For certain joints it is also possible to use 
hot-melt adhesive; the instructions indicate where this is the case.
Working with Zacki ELAPOR® 
Zacki ELAPOR® has been developed specically for glued joints in our models which consist of moulded ELAPOR® 
foam parts. 
Please observe the following points in order to obtain perfect joints: 
•  Avoid the use of activator. ‘Kicker’ signicantly weakens the joint. We advise leaving joined parts for 24 hours to obtain 
maximum strength, particularly when the glued area is large. 
•  Activator should only be used for temporary, small-area joints (‘tacking’). Spray a little activator on one surface, and 
allow it to air-dry for about thirty seconds. 
• To obtain maximum joint strength you should lightly sand the surface with 320-grit abrasive paper before applying glue. 
Bent parts - actually don’t exist. If you nd that a component has taken up a curve, perhaps after being trans-
ported, it is easy to straighten again. In this respect ELAPOR® behaves  in a similar  way to metal:  bend the 
component back slightly beyond the correct position, and the material will then spring back to its proper shape 
when released, and maintain it. There are limits, however - don’t overdo it! 
Bent parts - really do exist. If you wish to paint your model, apply MPX Primer # 60 2700 to the surfaces, wiping it on 
very lightly as if you were cleaning the model. Paint must always be applied thinly and evenly, otherwise the component 
will warp. Then you really will have bent parts, and they will also be heavy and perhaps even unusable. We have found 
that matt-nish paints produce the best visual effect.
