Zinc tubs are ideal for nostalgic mini garden ponds. The containers may well show some rust. This emphasizes the rustic look all the more. A leak, on the other hand, is problematic. Luckily, the leak was quickly fixed. On this page you will learn how to seal your zinc tub.

Ways to fix a zinc tub

silicone

The all-rounder silicone is probably the first thing that comes to mind for keen do-it-yourselfers when an object needs to be sealed. However, the remedy is not always as effective in use as assumed. Whether you can seal your zinc tub with silicone depends on the type of use. If you use the tub as a flower bed and only fill the container with soil, the use of silicone is unproblematic. However, if your zinc tub houses a mini pond, a silicone seal will not hold up.
When applying, it is important that you always work on the outside wall.

Seal with pond liner

If you want to seal a mini pond, you should use pond liner. You use this to lay out your zinc tub. Make sure there are no wrinkles.

fiberglass mats and synthetic resin

Two other useful tools are

  • fiberglass mats
  • and synthetic resin

You can get both of these items in car dealerships, with a bit of luck even in craft shops.
When sealing, proceed as follows:

  1. Pour the viscous resin into a tub.
  2. Dip the mat in.
  3. Place the mat over the leaking zinc tub.

Attach spare parts

Zinc trays are mostly made of the same material as your gutter. Do you have any waste left over from the assembly? Then just solder these onto the small crack. However, you should first consider whether the effort is really worth it. Soldering irons have a high cost that is often far too expensive to repair tiny cracks. However, if you have the opportunity to borrow the tool, it is definitely worth using.

tips

You have never worked with a soldering iron? Then ask a roofer for help.

alternatives

Perhaps the repair is superfluous. If the hole is at the top of the zinc tub, simply fill the tub with shallow water and plant it with aquatic plants that thrive even when the water level is low, such as:

  • filled marsh marigold
  • heart-leaf frog spoon
  • fresh green Cyprus grass
  • arrowhead
