Bonding, sealing and varnishing

Which techniques and which products can be used to achieve perfect results in model making? At ScaleMonkey, we have noticed time and again that more and more questions are arising in this area. The global market and new media such as social networks, forums and model-making events are creating new and even better products every day.
At best, articles are advertised that are ideal for their intended use, but not for everything. You should carefully consider whether you really need this. Unfortunately, there are also dubious characters and a lot of charlatans who re-label inferior products and market them as high-end. In most cases, people later doubt their own abilities because they are supposedly using a “super” product.

We would like to emphasize in advance that our recommendation is aimed at the construction of wooden-style models, i.e. real model building.

Bonding and gluing

Especially when it comes to gluing or bonding wooden parts on ships or airplanes, you often hear hair-raising stories, but there is only one correct answer: wood glue (white glue). Anything else is just a waste of money and has no place in proper models.
Here you should rely on the leading manufacturers and preferably use a waterproof white glue, such as Bindan D3 propeller glue or Ponal Express.

A little tip: stock up on glue before winter. Delivery of these glues is no longer possible at temperatures below 0° Celsius, as they could otherwise be damaged.

These glues have the advantage that they can be easily diluted with water for certain applications and can therefore be better dosed. Excess glue can be easily removed with water as long as it has not dried.
Now, unfortunately, white glue takes about 12 hours to harden and sometimes you have tricky areas to glue that can’t be permanently held or fixed. In such cases, we use superglue to first fix the parts with small dots and then fill the gluing areas with diluted white glue.
Syringes from the medical sector with 1.2 mm needles are ideal for this purpose.

For hulls, especially in model shipbuilding, which are built with frames, the aim is to achieve a high level of stability. Due to the many curved surfaces, the bonding surfaces are often not optimal. It is advisable to coat the entire fuselage with thick resin afterwards. This fills any cavities and glues the entire fuselage into one unit.
We use a 40-minute resin for this, which can be thickened with thixotropic agent as required.
If additional stability is required in some areas, it is possible to fill these in advance with the resin thickened with cotton flakes. This is particularly helpful in the bow area or with engine mounts.
