Sand & Ballast Freeze is capillary action acrylic adhesive with very low surface tension formulated to bond loose material such as sand, gravel, rubble or ballast. Allows for bonding together very tiny, even micronised grains, without disrupting the structures they are forming, tested with both fine 40 µm sands (0,04 mm) and coarse gravel up to several millimetres in diameter. Saturated terrain, can be further shaped after application. Making foot prints, dunes, tire or track prints in wet structures is easier than before!
Dealing with loose materials easier then ever! Simply form your structures from sand, gravel, ballast or gravel and then saturate them with this capillary action adhesive using supplied dropper bottle. Shapes are intact and natural, glue itself is 100% invisible once dry. You can spray a finished structure afterwards or leave it in its original colour.
With Sand & Ballast Freeze you will be able to make dioramas in a complete new way. City ruins, industrial sites, railways, sandy and rocky beaches will look better than ever!
You can fix virtually any kind of loose material. You can leave it in it’s original colour or airbrush over like we did with the sand to the right.
How much terrain will I be able to model?
Effectiveness the product is high. You will be able to fully saturate 1150 cm² of terrain (equivalent of a 33×33 cm diorama, layer 0.5 cm thick )
How long does it take for the adhesive to bond?
The glue itself dries within around 30 min, actual structure drying time depends on what material you use and how thick a layer is. Finer materials take longer dissipate solvents than say gravel. Thick layers (1 cm+) take longer to dry than thin ones as solvents have longer distances to travel from the centre to the surface. As a typical diorama terrain is irregular, we recommend leaving your terrain to dry for 24-48h with absolute minimum of 12h, so that nothing is left to chance. You can use hair drier to expedite things.
What is the open time of the product?
Depending on ambient temperature and materials used open time is around 60 – 120 minutes.
What tools to use?
Use supplied dropper bottle to easily apply the adhesive. Hold the spout very closely to your terrain, squezze it very gently and saturate it with adhesive so as to avoid the “rain drop” effect. Drops will slide from the spout and penetrate the structure.
How to make imprints such as tank track or tire marks?
You can make imprints around 30 – 45 minutes after application, no special technique needs to be involved. Best imprints can be made in fine sands.
What’s the minimum and maximum grain size I can fix?
Sand & Ballast Freeze is very well balanced. We have tested the product extensively with both fine sands 40 µm (0.04 mm) and coarse gravels 2-8 mm, with bigger stones mixed in. In case of fine sands there was no slow drying problems which is often the case with similar products. In case of gravels resulting bond was very strong.
Can I use this adhesive to fix separate objects such as single stones?
The glue has low surface tension and it is formulated to penetrate structures made of loose material. To fix single objects such as extra stones, pieces of wood, bushes please use one of VMS PVA adhesives or Flexy 5k CA adhesive for dioramas. PVA bond slowly and allows for a lot of manipulation while Flexy 5k CA bonds almost instantly
I overdosed the adhesive and the glue is bleeding at the base of my structures.
That’s no biggie, simply sprinkle more sand or gravel over the excessive glue.
