On this page, you’ll find all the information you need on how to find, use, and automate 
Sealant production in Starfield. We detail some of the best planets and biomes to find Sealant, as well as provide an exhaustive list of all Sealant uses in Outpost building, weapon and spacesuit modifications, and more!
Sealant is a glue like substance that is common in crafting, research, weapon mods and more.
Best Sealant Farming Locations in Starfield¶
Both flora and fauna can be a source of sealant but you can only automate Sealant production using the Greenhouse. The bonus is that the Greenhouse is a more economical module than the Animal Husbandry Facility as all you’ll need is water and power to start producing sealant. Below we’ll provide a list of different flora and fauna that can be harvested for Sealant.
| Flora/Fauna | Biomes | Planet Location Examples |
|---|---|---|
| Scarlet Hillfrond (flora) | Hills, Mountains, Rocky Desert | Heisenberg II,  Heisenberg System |
| Pack Hammersaur (fauna) | Savanna, Hills | Rana III,  Rana System |
| Kingshead Bugloss (flora) | Volcanic, Coniferous Forest | Jaffa III,  Jaffa System |
| Sandclaw (flora) | Mountains, Sandy Desert, Deciduous Forest | Nesoi,  Olympus System |
| Herding Sunflower Filterer (fauna) | Frozen Hills, Rocky Desert | Altair II,  Altair System |
| Tremor Root (flora) | Rocky Desert | Altair II, Altair System |
| Herding Brainblimp Filterer (fauna) | Frozen Mountains, Craters | Andromas III,  Andromas System |
| Cold Cave Nettle (flora) | Frozen Plains | Procyon III, Procyon-A System |
| Swamp Bottle Root (flora) | Swamp, Wetlands | Gagarin, Alpha Centauri |
| Herding Cagebrain Herbivore (fauna) | Tropical Forest, Deciduous Forest | Tau Ceti VIII-B,  Tau Ceti System |
To be able to automate the production of Sealant, you’ll need to first scan a flora to 100%. Then, you’ll be able to set up a Greenhouse to start your own supply of sealant. Head over to our guide on how to set up a Greenhouse for more information!
You can also purchase Sealant with relative ease from different vendors found throughout the Settled Systems. Our top vendors are the Jemison Mercantile in 
New Atlantis, the Goods stores in 
Neon, and The Depot at 
The Key (Crimson Fleet only). Any 
Trade Authority shop will also likely stock Sealant as well.
What is Sealant Used For?¶
Sealant is a major component for crafting loads of different things in Starfield. From Outpost buildings to Research Projects to Weapon Mods, you’ll definitely need a constant supply of Sealant to deal with it all! Below, we’ve given an exhaustive list of all Sealant uses, and also provided additional information regarding other required materials and skills.
Outpost Building, Furniture and Decoration Uses¶
Sealant, given its a strong glue-like substance, is naturally well suited to building and crafting furniture and outpost buildings. You’ll find that many outpost structures require Sealant and below are some of the most important structures that require sealant. You can also head over to our Decorative Items and Furniture Items guides for furniture and other decor that use sealant! It is also used in the building of all hab buildings for your outpost - you can check out our guide on those here.

One of the most common uses of Sealant is in weapon modifying.
Pharmaceutical Lab Uses¶
In addition to weapon and spacesuit modifications, Sealant also has a big part to play in the production of Aid supplies at the 
Pharmaceutical Lab. You’ll need x1 Sealant and x1 Fiber to make 
Bandages, and you’ll also need x1 Sealant and x1 Structural to make 
Immobilizers. These supplies can then be used to craft higher-tier, more effective medical aids - as long as you’ve done the research!
Sealant is an important material in crafting Bandages.
