Painting, gluing, fixing gaps, and protecting your Primal Bee hive — all with the right products.
Your Primal Bee hive is built from high-density EPS, a durable insulating material with one simple rule for any product you apply: water-based only. Solvent-based paints, glues, and cleaners will damage EPS. This guide covers safe products, painting best practices, assembly gluing, and how to address minor cosmetic or fit issues so your hive stays in good shape season after season.
For assembly steps, see Assembly and maintenance. For repairs and structural issues, see Repairs and structural issues.
Safe products to use on your hive
The golden rule: always use water-based products on your Primal Bee hive. Anything containing oil or alcohol solvents will damage the EPS material.
Glue — Water-based carpenter glue such as Titebond or Gorilla Glue
Paint — Water-based primers and water-based paints only
Top coat — Water-based polyurethane (e.g., Varathane Water-Based Polyurethane or Minwax Polycrylic)
Vinyl glue — Safe only if confirmed solvent-free
Important: Always check labels for "water-based" or "water cleanup" and confirm no solvent ingredients are listed.
Painting your hive
Painting is optional but beneficial. A coat of water-based paint enhances surface hardness, slows UV degradation, and lets you customize the color.
Natural hive color — A light, warm, neutral tone (not bright white) that may gradually shift with UV exposure.
UV discoloration — Purely cosmetic and doesn't affect thermal performance or structural integrity.
Exterior only — Paint the outside for UV protection; leave the interior unpainted so bees can coat it with propolis, their natural antimicrobial layer.
Tip: Adding paint to the interior can interfere with the bees' propolis envelope and introduce unnecessary compounds into their living space.
Gluing supers and nest boxes
When you glue the supers, you're tightening the coupling-profile seal — Pillar 3 of the Three-Pillar thermal system. A drafty hive doesn't perform.
Supers — Glue is recommended to achieve a complete seal and maximize insulation. Apply water-based carpenter glue only.
Nest box — Gluing isn't required thanks to the interlocking design, but you can add water-based glue for extra reinforcement.
How to fix gaps or loose seams on a nest box
Remove all nest frames and brood box frame rests, then disassemble the nest box (face and back panels separate from side panels).
Reassemble while applying firm pressure to confirm a tight fit.
If the fit is tight, disassemble again and apply a quarter-sized drop of water-based carpenter glue into each peg hole.
Reassemble and hold components tightly with the provided safety strap or strong tape while the glue dries.
Repairing wall separation on the nest
In rare cases, small EPS bulges on the bottom board can press against the front and rear walls, creating a minor gap. This doesn't affect hive performance or colony health.
Temporary fix — Use the provided strap or a ratchet strap to close the gap, especially useful if bees are already clustering for winter.
Permanent fix — When the colony isn't clustered, lift the hive, remove the bottom board, and trim the small EPS bulges pressing against the walls so they sit flush.
Replacement bottom board — Share your order details with the support team and a replacement will be sent for warmer-weather installation.
Tip: Contact the team for a walkthrough with reference photos showing what the bulges look like and how to remove them.
Opening supers
Use a hive tool gently between the seams. Bees use less propolis to weatherproof the Primal Bee hive thanks to its precise coupling-profile fit, so less force is needed compared to a wooden hive. For tool details and frame-by-frame technique, see Using the Primal Bee hive tool.
FAQ
Does sun discoloration affect the performance of the hive?
No. UV discoloration is purely cosmetic and doesn't impact the hive's thermal performance, structural integrity, or any other functional aspect.
Can I paint my hive to protect it from UV damage?
Yes. Painting with a water-based paint will enhance surface hardness, slow UV degradation, and improve long-term durability. Use water-based paints only — solvent-based paints can damage the EPS material.
What type of glue, paint, or top coat is safe to use on the hives?
Water-based products only: water-based carpenter glue (Titebond or Gorilla Glue), water-based primers, water-based paints, and water-based polyurethane. Avoid anything with oil or alcohol solvents — they can damage the EPS.
What color are the hives naturally?
The Primal Bee hive's natural EPS color is a light, warm tone — not bright white, but a neutral, natural shade. Over time, UV exposure can cause gradual surface discoloration, which is purely cosmetic and doesn't affect performance. You can paint the hive with any water-based paint to customize the color and further protect the surface. Avoid solvent-based products, as they can damage the EPS material.
Should I paint the inside of the hive?
Paint the exterior only for UV protection and surface hardness. Painting the interior is unnecessary and not recommended — bees naturally coat the inside with a thin layer of propolis, which has antimicrobial properties and is part of their natural hygiene system. Adding paint could interfere with the bees' propolis envelope and introduce unnecessary compounds into their living space. If you do paint any part of the hive, always use water-based paints only.
What brand of water-based polyurethane would you recommend for the hive?
Products like Varathane Water-Based Polyurethane or Minwax Polycrylic are popular, widely available options that work well on EPS surfaces. The key requirement is that the product must be fully water-based — avoid any polyurethane containing oil or alcohol solvents. When in doubt, check the label for "water-based" or "water cleanup" and confirm there are no solvent ingredients. A water-based polyurethane top coat will enhance surface hardness and provide additional UV protection.
Do I need to glue the hive supers together?
Yes — gluing the supers is recommended to achieve a complete seal and ensure maximum insulation. Use water-based carpenter glue only, and avoid any products containing oil or alcohol solvents.
Is it necessary to glue the hive nest?
The nest doesn't require gluing — its interlocking design already provides a tight seal and excellent insulation. If you'd like to add glue for extra reinforcement, use the same water-based adhesive guidelines as for the supers.
What kind of glue is safe to use on the hive?
Use only fully water-based glue to protect the EPS surface. Water-based carpenter glues such as Gorilla Glue or Titebond are excellent choices. Water-based polyurethane is also safe as a top coat or sealant.
Can I use vinyl glue on my Primal Bee hive?
Yes, but only if the vinyl glue contains no solvents. Always confirm the product is solvent-free before applying it to EPS — solvents will damage the material.
Will solvent-based glues damage the hive material?
Yes — solvent-based products, whether glue, paint, or cleaners, can damage EPS. Always check labels and use water-based products only.
Why is there a small gap in my nest wall?
In rare cases, small EPS bulges on the bottom board can press slightly against the front and rear walls when everything is assembled, creating a minor separation. This is a rare manufacturing detail and doesn't affect hive performance or colony health in any significant way. If you'd like help addressing it, reach out to the team for assistance.
Will a small gap in the hive wall harm my bees or affect performance?
No. Minor wall separation of this type doesn't significantly impact hive performance or colony health.
Can I use a ratchet strap to temporarily close the gap?
Yes — using the provided strap or a ratchet strap to close the gap is the ideal temporary solution, especially if the bees are already clustering for winter when you discover the issue.
Can I get a replacement bottom board to fix the wall separation?
Yes. Share your order details with the support team and a replacement bottom board will be sent for installation when the weather is warmer and the colony is no longer clustered.
How do I permanently fix the wall gap on my own?
When the colony isn't clustered, lift the hive, remove the bottom board, and trim the small EPS bulges that are pressing against the walls. Once trimmed, the walls will sit perfectly flush. The team is happy to walk you through the steps and share reference photos.
How do I fix gaps or loose seams on my nest box?
Remove all nest frames and the brood box frame rests, then disassemble the nest box (face and back panels separate from the side panels).
Reassemble while applying firm pressure to test for a tight fit.
If a tight fit is achieved, disassemble again and apply a quarter-sized drop of water-based carpenter glue (such as Gorilla Glue or Titebond) into each peg hole.
Reassemble the components and hold them tightly in place with a strap or strong tape while the glue dries.
Contact the team if you'd like a walkthrough.
What type of glue should I use to fix the nest box seams?
Water-based carpenter glue — Gorilla Glue, Titebond, or a similar product. Never use solvent-based products on EPS — solvents will damage the material.
How do I keep the nest box components tight while the glue dries?
Use the provided safety strap or strong tape to hold the components firmly together while the glue cures.
How do I safely pry open the supers?
Use a hive tool gently between the seams. Bees use less propolis to weatherproof the Primal Bee hive thanks to its precise coupling-profile fit, so less force is required compared to a wooden hive.
