  1. .When I first saw this I thought - I had to get it. The amount of times it would have been handy to have a tube to either fix a leak or just put something in place and keep it there. So many things you can do with this. Live Rock, Marine use or fresh water. Fix leaks, stick items in place - does just about everything.... Seals leaks in concrete butyl PVC glass and many other surfaces. Gold Label Underwater Sealer Can I actually use this in wet conditions ie rain or under water? Yes. Gold Label is able to stick to a surface by displacing moisture from the surface. Will it cure under water? Yes, as it uses the oxygen in the water to cure. Does temperature affect it? In its uncured state, it does. It will not cure below freezing and it will be very slow curing under 5°C. Optimum temperature is 16°C. I cannot get it to stick 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 approx 5mm and gently attach 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) Can I use it to repair gutters, roofs etc? Yes, Gold Label will stick to most surfaces. Will it stick to vinyl? Yes, make sure surface is clean and sound, and abrade lightly. 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 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 eg 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 line 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. Do I have to drain the pond / tank before using Gold Label? No, you can use this under water to bond practically anything. Can I use Gold Label in swimming pools / spas? Yes, this will adhere even in chlorinated water. Can I fix a crack in a concrete pond / pool? Yes. First vee-out the crack to approx 10-20 mm and fill with Gold Label. If concrete is powdery, use primer first.
  2. Hi. First post here I am going to attempt my first DIY background in the next few months. I have been reading lots on the subject. I am going to use styrofoam coated with concrete then sealed with (most likely) a pond sealer to avoid the pH spikes. The only problem I have encountered is the lack on info on the subject. Most DIY's just state to coat with a pond sealer but do not mention a brand. What brand of pond sealer is best? I have read some can turn white over time. Anyone experienced this? Any brands worse than others? If not pond sealer, what epoxy can you recommended? Would prefer stuff I can just pick up at bunnings or masters. I have seen mention of crommelin and pondtite. Anyone used these? This is all going in a frontosa tank so I don't want to take any chances. Thanks!
  3. Does anyone know if the Cement driveway epoxy sealer (crommalin i think it is) sold at Bunnings is safe for use in fishtanks??
