Working with resin

This article runs through the basic techniques and tools you should be using when working with resin miniatures or models. If you need any extra guidance please do not hesitate to get in touch:


Firstly when opening your Hive City Terrain product take care to check your kit for mould release. Mould release is used to ease product removal from the moulds and to increase the shelf life of the moulds.

Wash any areas which are slightly glossy or greasy with warm soapy water and a sponge. This will remove the mould release easily.

Excess Resin and Resin Gates

Excess resin and flash lines are par-for-the-course when working with pressure cast resin. They are areas where resin creeps out through the joins in the mould. These can be removed by using a modeling knife. Use a file to then ensure the area is smooth and ready for priming.

Resin gates are areas where liquid resin is poured into the mould. Often in pressure casting it is vital that more resin is used than needed; this makes sure the entire mould is filled. These are best removed close to the model with a pair of modelling clippers. Then the remaining excess needs to be filed smooth, ready for priming. In some cases resin gates may need to be removed with a modeling or hack saw. Please remember that resin dust is bad for you and you will need to wear a dust mask when working with resin models


Sometimes resin can warp. There are main reasons for this, however at Hive City Terrain the resin we use rarely warps after it has cured. None the less, if you do experience some warping you can easily return the piece to its original shape. Just submerge the warped piece into a bowl of hot water and allow the resin to warm through. Once warmed the resin piece will become flexible. Simply bend the resin piece slowly and with care to its intended shape and hold until cooled. Careful not to burn yourself with hot water!


Hive City Terrain models are pretty self explanatory but it is recommended that you try a dry run of building your model before gluing any pieces in place. This will help you notice whether any extra filing is needed and show you the best order to build your model in. Super glue is recommended for gluing your models. Be careful not to glue your hands to the model or table!


Once your model is built, you will need to prepare it for painting. Personally I have found the best way of priming resin models is a thin coat of grey car primer from Halfords (UK). Then, once the primer has dried, spraying the base coat over it. Remember to always wear a mask and spray in a well-ventilated area!
