Gold Label Pond & Aquarium SealerHutton Aquatic Products

This clever sealer will allow you to repair cracks/holes etc or bond items to your pond/aquarium/tank underwater and is safe for fish! Being non-toxic, solvent and isocyanate free there is no need to drain your pond or disturb your fish any more in order to make a repair! With the strength of 4 times a normal silicone sealer it will bond almost anything to anything including drains, gutters, tanks, boats, rockery, coral, decking, concrete (please note, if applying to concrete, a PVA or concrete primer will be needed prior to application to seal any loose surfaces), wood, PVC, glass etc. It will start to work instantly and will continue to cure over 24 hours. Available in Black, Clear & White in 290ml cartridges and Black & Clear in our “One Shot” version. Please note; cure times vary between colours and the amount applied.

For best results ensure surface is clean and free of grease/algae etc. Pipe the sealer using a sealant gun directly on to the surface you wish to seal/bond, ensuring a thick enough bead in order for the product to work. Gold Label Pond & Aquarium Sealer is NOT glue but a sealant, so DO NOT PRESS DOWN/COMPRESS FLAT. (Please refer to the instructional video on the website or our YouTube channel should you need a demonstration). For bonding where there is movement (expansion/contraction) between surfaces, allow a minimum 2mm thickness of beading. For best results when attaching different liners together, use 2 lines of beading 150mm apart. Full curing time is approximately 24 hours but will be touch dry after 2-3 hours. If using the clear version of the sealer, full cure time is approximately 36 hours as this version is less dense. Please note: should livestock be present, protect from ingestion whilst curing. (See FAQ should you have queries). Should you wish to paint over the sealant, this can be done up to 4 hours after application. Do not use below 10 °C air or surface temperature.  Shelf life up to 12 months in ambient conditions (10-25°C).

  Can I actually use this in wet conditions i.e. rain or under water?

Gold Label is able to stick to a surface by displacing moisture from the surface. It works in temperatures between 5°C – 40°C. Please note; it will not stick to wet or dry concrete without using primer ie:-PVA or concrete primer.

  Will it cure under water?

Yes, as it uses the oxygen in the water to cure.

  Why does Gold Label Sealer need primer on concrete?

Concrete has a loose surface, and if the sealer bonds to a loose surface it will come off. A primer is used to bind the surface, allowing the sealer to get a solid bond.

  Can I use it to repair gutters, roofs etc.?

Yes, Gold Label will stick to most surfaces. If using on plastic, fibreglass or steel (smooth surfaces) etc., abrade first to ensure good adhesion.

  Can you use it to bond to stainless steel or galvanized steel?

If using on stainless steel, abrade the surface first using wire wool, and with galvanized steel just degrease as normal using “Gold Label Cleaning Solvent”. This applies to both our paint and sealer products.

  Will it stick to vinyl?

Yes, make sure surface is clean and sound, and abrade lightly.

  How long after using Gold Label Sealer can I refill the pond?

If the patch that has been sealed is on the side of the pond, it can be refilled immediately. If however, the seal was at the bottom of the pond, wait for 24 hours to refill, due to the weight of the water will compress the sealed patch compromising its ability to seal affectively.

  Does temperature affect it?

In its uncured state, it does. It will not cure below freezing and it will be very slow to cure in temperatures below 5°C. The optimum temperature is 16°C.

  I cannot get it to stick

The most common reason is trying to use it as a glue! It is a sealant which needs a body of product to work. If you squash the surfaces to be stuck then the area cannot affect a cure. Always apply a bead of approx. 5mm and gently attach the object or liner patch to leave a bead of approx. 2-5mm. (Do not be tempted to pull it off to see if it is stuck before 3 days as temperature and thickness of sealer will affect the cure rate). It will also, not stick to algae, so make sure that your pond liner is cleaned deeply using a stiff brush! Another reason could be that the water or surface is too cold, so ensure your repair is done in temperatures referred to above.

  Do I have to use a pond liner patch to fill a hole or split or can I use the sealer?

A small split or hole (no larger than 10mm) can be filled in with the Gold Label Sealer, without the need to use Pond Liner Patches. To do this, fill the hole or split with the sealer, ensuring the sealer has spread to both/all sides of the liner that is split. This will create a plug in the liner, sealing up the hole.

  I read that in order to seal up the bottom drain, I will need to drain the pond first. Is this correct?

If you can reach the bottom drain with water still in the pond, then the drain can be sealed with water in the pond still. The surface will still need to be clean and free of algae etc. Preferably release the clamping ring pump sealer into the seal area and re-clamp rings. For dry sealing apply a bead around sump to liner and leave for 1-2 hours before clamping down tightly for best results.

  Do I have to drain the pond/tank before using Gold Label?

No, you can use this underwater to bond practically anything.


  Can I use Gold Label in marine tanks?

Yes, there is no difference in performance between fresh water and salt water.

  Can I use Gold Label in swimming pools / spas?

Yes, this will adhere even in chlorinated water.

  Can I use Gold Label to stick living rock or coral?

Yes, because Gold Label is an inert non-toxic product it can be used safely on coral or living rock.

  I need to use acrylic glass for safety in my pond / tank. Will Gold Label stick the acrylic to the frame?

Gold Label has 4 times the bond strength of silicone on acrylic and has been used in major installations using acrylic sheet.

  Can I use Gold Label to fix equipment e.g. pumps/ filters to the side of ponds or tanks?

Yes, make sure you bed the equipment on a bead of sealer at least 5mm. This is to allow slight movement between the two surfaces and support for 24 hours to allow the sealer to cure before any weight is put on it.

  Can I join two pieces of liner together?

Yes, by putting two beads of 5mm diameter, 100mm apart on the overlap. Then gently run your fingers over the liner to make sure the sealer has connected both pieces of liner. DO NOT PRESS FLAT. By having two beads of 5mm, the liner can expand and contract without tearing and it will allow for any imperfections in joining of the two liners. Please refer to the “Gold Label Pond Liner Patch” Method of use.

  Can Gold Label be used to stick rockery/decking/slabs/slate etc. to the surround of the pond or the liner?

Yes, Gold Label has a very strong bond to most surfaces. If the product you wish to stick is powdery, it is advisable to seal it with a primer first – contact us for advice.

  Can I use the sealer on top of pond paint or marine ply

Yes apply as per method of use.



  Can I fix a crack in a concrete pond / pool?

First V-out the crack to approx. 10-20 mm and fill with Gold Label. If concrete is powdery, use primer first PVA or concrete primer.
