AQUARIUM SAFE Silicone, Glue, Cement and Adhesives.
Today, I want to talk about my favorite silicones glues cements and adhesives that I use in and around my aquariums and for my projects So the first thing we should talk about is silicones that is the number one question that I get about Aquarium adhesives is what type of silicone can I use and what type of silicones are safe? Well, that’s not necessarily an easy question to answer I can tell you what I use But depending on where you’re located in the world you might have zero access to these So let’s start out by telling you what I use in some recommendations And then we’ll follow it up by what you can look for in other types of silicones if you can’t find these the number one [silicone] that [I’ve] been using and I’ve been using for about ten years now is Ge silicone one window indoor it’s a hundred percent Silicone with no additives the other type of silicone that I use which is in here right [now] is ge Scs 1200 it’s Also a great silicone Now when I can’t get to a store that sells this or I can’t find it I go to my local home hardware and get weather shield Which specifically states that it’s safe for aquariums right on the packaging. I need to be clear here [I] find zero difference in whether I use this one or this one or [any] other types of silicone? [I] find they have the same strengths same consistencies, and they’re about the same prices [I] paid between five and eight dollars for a large Tube like this when I’m building aquariums this is the size that [I] use and For smaller tubes like these I’ll pay closer to three to five dollars usually I stock up on silicones when I see them go on Sale though the big Tubes I use with a caulking gun to build aquariums [and/or] some of the bigger jobs that I need to do Smaller Tubes, I like to use these for a lot of smaller jobs like installing baffles inside of a sump and or any other small little job I need obviously this is a lot easier to get in and [around] everything then a big caulking gun with this on the end So what if you can’t find the ones that I use well the number one thing [that] you want to look for is that it? says a hundred percent silicon then it has additives you want to look for if it says Mildew resistant or Mold inhibitors, or anything like that if it does stay away [from] it those are what are not safe for your aquarium? [if] you’ve ever used silicone before it comes out in a very thick substance typically taking about 10 minutes to start Curing and by that it only starts to cure on the on the outside of it And we call this skinning where it forms a cured skin on the outside The inside of the silicone will not be for a bead of silicone. That’s about six millimeters in diameter It’s going to take about 24 hours for that to cure for something bigger you typically need a little bit longer for [example] for big glass tanks I’ll wait three to seven days before I start a test [film] but for something as simple as a Small tank like a Thirty gallon and or if your [riesling] in your tank 24 hours is sufficient if you’re still not sure What aquarium silicone to use ask? join a local aquarium club join a local forum get on a Facebook group and ask around and find out if anybody in your area knows of an aquarium safe silicone, that’s commonly available to you So like I said if this doesn’t apply to you do your research and ask around locally okay on to cements I used to build Acrylic aquariums when it comes to working with acrylics or even Plastics for that matter my favorite product to use is well done now Well Dawn comes in a variety of different types including [weld-on]  which is water thin and [weld-on] 16 which is a more of a syrupy type of cement both doing pretty much the same thing the differences are pretty clear though well don 4 is meant to Bond acrylic on a molecular level it works by softening the Acrylic first and once both edges of the acrylic Soften within minutes the well Dodd 4 actually evaporates leaving behind a Welded Seam of acrylic that is bonded on a molecular level [well] Don 4 comes in a variety of sizes This is actually 473 millilitres. I paid about 15 bucks for it for example [a] hundred gallon. Tank will only take me [about] 20 20 to 30 milliliters of well Don  to build it so [as] you can imagine I could build a lot of aquariums with just this one pint when it comes to weld on 16 This is a little different. It’s still great for bonding acrylics, but it’s almost like silicone Whereas once you apply it. It actually remains. It doesn’t evaporate Being more syrupy in consistency it means that it can also fill in gaps and bond things that are not perfectly flat It also doesn’t cure nearly as fast you can still move things around for about the first five minutes But after ten minutes it becomes a more permanent fixture after 24 hours It’s fully cured a little thing like this will cost me about [eight] bucks which might sound expensive But it’s entirely worth it once you apply it to acrylic It’s definitely permanent now if you can’t find weld on for all you need is Methylene chloride Which is actually its main ingredient if you can’t find Methylene chloride Chloroform actually works as well both being water thin but cure a lot faster So while you have about one to two minutes to work with your acrylics with this you only have 10 to 20 seconds to work? With Chloroform or Methylene chloride? Okay, let’s move on to another cement This is hugely popular in the Hobby And it’s just simple Superglue or I like to call it [krazy] [glue] when it comes to using crazy glues This is for really small jobs Where you simply need a couple of small things to stick together quickly the gel type is what I use the most [this] is actually most Popular for attaching plants to things like rocks and or driftwood [any] super glue is fine because once it’s cured and since you’re using such A small amount it’s harmless now why use this instead of this well? Well done 16 is typically best for Acrylics and plastics Whereas [Superglue] will bond to more surfaces with that said this is also a bit cheaper being 5 bucks and far more and far more common to find a glue gun is Extremely useful in the aquarium Hobby especially for the do-it-Yourself hobbyist and When you need bigger jobs done and need something to cure quickly instead of waiting 24 hours like you would for silicone This will actually go on in the same consistency of silicone yet cure a lot Faster with that said it’s not really good to see leaks however. It is great to bond things together So if you’re building your own decorations [or] even doing some repairs a glue [gun] is perfect for it once cured It’s fine for underwater use as well Now you be thinking that a glue gun is expensive But I got this for ten bucks at Walmart [and] a bag full of the glue refills for about five bucks This is going to last me for months cure times for this is typically under 30 seconds the next thing I want to talk about is this new product called Bondic now I’m not sponsored, and I didn’t get any of this for free I bought it at my local hardware store in fact they only cost 15 bucks [apiece] I stocked up on them because over the last few days I’ve been using this for [a] lot of different things, and I’ve been completely impressed so far basically the way It works is it’s shaped like a little pen you take the top off and you squeeze the pen and out comes a little gel now that gel will never cure until You shine this ultraviolet light on it with about four seconds of shining the light on it It cures now. It cures to a consistency is much like The glue gun except it cures a slightly harder I found now could be used to bond things together. You [can] build up in layers. You can sand it and shape it You can use it to fill in things it can actually be used underwater And you can cure it underwater you can even paint it according to all this packaging. I’ve used it for a number of things already including using it in place of soldering Which this actually ended up working really well for that if you made it this far in the video You’re obviously into do-it-yourself aquarium projects Just as much as I am and if that’s the case I highly suggest picking up my book the ultimate do-it-yourself Handbook for the do-it-yourself aquarist. You can get your signed copy at the king of diy Com anyways Hope that you guys enjoyed today’s video. I certainly enjoy making them for you every Thursday I do a topic of the week just like this and on Sundays. I do a do-it-yourself aquarium project So if you didn’t enjoy today’s video join me next Sunday or next Thursday, and I’ll have something totally different
