The ability to create your aquarium out of wood has been revolutionized by Liquid Rubber. Previously you would not have been able to create intricate designs or even use wood. With the flexibility and ease of use provided by Liquid Rubber, you're only limited by your imagination.  Here's a couple examples of some pretty neat designs.  How to create Ponds and Pond Repair with Liquid Rubber


First off, Liquid Rubber NeoPond Sealant is an excellent choice on how to waterproof an aquarium.  It has 100% waterproofing ability and excellent adhesion to give a completely seamless membrane.  It can be rolled on, brushed on and even sprayed on with a high quality piston pump (used in large jobs).


Initially you'll want to bridge all seams, glass, cracks and gaps with Liquid Rubber Seam Tape.  What this does is ensure a bulletproof system.  If your aquarium is going to leak, it most likely will be at one of these areas.


Once the Liquid Rubber Seam Tape has been applied, you can start applying the Liquid Rubber NeoPond Sealant.  The best way to build your membrane is in multiple coats.  The thicker you put it on, the longer it takes to cure.  Curing ranges 6-8 hours per coat depending on temperature and humidity.  The best way to determine is by touch.  Once the final membrane is applied, it's best to leave curing 4-7 days before use.

Coverage rate is 1 gallon for every 40 sq ft final coverage.

Silicone is not compatible with Liquid Rubber.  If you need to use a type of caulking, a butyl rubber is recommended.


Liquid Rubber products are water based making them safe for fish, they contain no solvents or VOC's.  You can find more information on our website for products and where to buy Liquid Rubber.
