How to Use Aquarium Silicone Sealant?
One of the first things you should do when preparing to apply silicone aquarium sealant is to read the instructions provided with the brand you have chosen. Although it is true that they are all used in basically the same way, the biggest difference you will find is how long each product takes to cure.
It is really important to make sure you are not using the aquarium before it is ready. Repair will not be delayed or water will be adversely affected. These products are non-toxic and safe for your fish, but only after you have had the right moment of care.
Ideally, aquarium silicone cures at a slow and steady rate. If it is too fast, there is a risk of proper surface adhesion.
There are a few ways you can use silicone sealant in an aquarium. One of the most common is with an aquarium that has been stored. Sometimes when you are ready to use it again you will see that it is no longer waterproof. Silicone can be used to repair a leak in this or any other situation.
Here is a general step-by-step method on how to seal a significant corner leak with silicone.
1. Completely empty the aquarium.
2. Use a razor blade to remove as much old silicone as you can. Why is this When applying the new silicone, you want it to come into contact only with the glass, not the old parts. The bond will not be as strong between the old and the new silicone layer as it will be between a new silicone layer and glass.
3. Clean the surface and brush with fine-grit sandpaper. This slightly stiffens the surface and forms a stronger grip.
4. Make sure everything is completely dry before continuing.
5. Use a silicone gun to apply a new layer of silicone inside the edges. Use duct tape or clamps to hold everything in place while it heals.
6. Smooth the silicone along the seams with your finger to remove any excess.
7. Allow the silicone to harden for the period of time recommended by the manufacturer.
This general method can be adapted for some different situations. Here are a few examples.
If you notice that there is a chip causing a leak, it is not necessary to replace the entire seam. Drain the aquarium a few inches below the chip. Clean broken glass with gloved fingers, then use fine sandpaper. Insert the silicone into the chip with a small piece of glass of similar size. Cover with wax paper and use masking tape to hold it in place until the silicone hardens. Then fill the tank.
Another reason why a leak might arise is if there is a crack in the glass that passes completely. To fix this, completely empty the aquarium and clean both sides thoroughly. The best way to do this is to scrape a razor blade into the slot to make sure small glass beads are removed.
Apply the silicone along the crack with your finger to smooth it evenly inside. Repeat on the other side. If you want additional reinforcement, add a thin sheet of glass to the inside of the crack with silicone to secure it in place.
Most silicone repairs will last a long time. In fact, if done correctly, they can last a lifetime. That being said, silicone repairs are more effective on a really used tank. What we mean is that if you fix a tank and then put it away and let it dry, those repairs will most likely have to be redone when you refill it with water.
There are also uses for silicone in addition to repair repairs. If you have rocks, slate, or wood that you want to place in your aquarium, silicone is one of the best things you can use to bond them together. You can also use it to repair broken aquarium decorations.
If you notice leaks in pipes or tubes, silicone is a great way to repair them. Simply place a bead over the leak and spread it out with your finger to make sure the entire area is sealed.
Again, regardless of how you’re using it, remember to let the silicone harden completely before putting it in the water.
How to Remove Aquarium Silicone from Glass?
There are some methods for removing silicone from glass. The first and easiest is to use a razor blade and simply scrape it. This is a quick and easy way to remove any silicone from the surface. With that said, you may find that if you have a lot to remove, this method can leave many bits behind.
If you need to remove the silicone from a large area or if you are trying to remove it from the corner seam, you will need some other consumables. Use a heat gun or hairdryer to blow hot air along the seam. A hair dryer will work but it will take much longer than a heat gun because it is not that hot. It is a good idea to wear gloves that protect against heat when using these tools.
Once the silicone is heated and more flexible, use a razor blade to scrape it. It is important not to heat it to the point it starts to melt. You just want it to be a little more flexible, so it’s easier to remove. You can use a utility knife to split the corner if you’re taking everything apart. After removing all you can and the glass has cooled down, use a rough sponge to wipe away any remaining bits.
