In a previous video I tested some grab adhesive using a jig like this using
some wooden blocks, I then used some hydraulic test equipment to see how much
force was required to remove each block. A couple of people weren't happy with
the outcome, one particular adhesive manufacturer got in touch and said that
a much fairer test would be to use stainless steel. So I've gone to the
trouble of cutting some stainless steel blocks like so and I've actually got
about 12 of those and then I've got some stainless steel which has been screwed
down here. So I'm going to repeat the test using stainless steel. Before I
stick down the blocks I'm going to clean each piece of stainless using methylated
spirits I'm also going to clean the plate that is going to be stuck down too.
So I've got some methylated spirits in a sprayer.
I'm now going to spray this onto all of the stainless I'm going to clean it all
thoroughly before we repeat the test using the stainless steel.
I want to start at this end and then I'm going to glue each one of the stainless
steel pieces all the way down the front of this sheet stainless steel.
I've cut off the nozzles so they are approximately all the same size that
should roughly give us the same size bead but it does of course depend on the
viscosity of the adhesive. So I'm going to start off at this end and the first
one we're going to use is Geocel The Works.
We will now turn that over and ensure I place that where there is no screw. Press it
down on the edge there and I'm going to apply a firm pressure. I'm not going to
take a marker I'm going to write on the stainless steel exactly what it is.
This has been left for over one week for the adhesive to cure fully. I am now going to start off
at this end and start off with the CT1 we're going to see how much
hydraulic pressure it takes to remove the piece of stainless steel from the
stainless steel plate.
As you can see that did not even hold as well as the wood which I tried in
the first test. The adhesive is still not dry on that and that has actually been in
the house for over a week. So it wasn't actually my idea to test this out on
stainless steel this was actually suggested to me as a test so I was
happy to oblige. I've done the test with stainless steel and it doesn't seem to be as good a
test as what it was when I used the timber. We will now try the Serious Stuff.
Now the No More Nails. That one just did not stick at all. Now the Uni Bond Mega Grip.
Again that's not stuck at all. This is quite a surprising test actually because a
lot of these adhesive's do say that they can be used on metal which is a very
vague term. They don't actually tell you which metals they do work on.
Now Adiseal.
Now the Sticks Like Shit.
Now Nemesis.
Now the Maximum Torque.
Now the Soudol Fix All.
And finally Geocell The Works.
I have actually done this test using stainless steel because somebody
suggested it. They were not happy with the way I did the first test using
blocks of wood. I have actually tried to do this test using some galvanized
steel and the metal didn't stick at all very well. So this time I used stainless
steel sheet and stainles steel pieces like so. I went to a great deal of trouble
cleaning them sticking them down and then these have actually been left in
the house with the central heating on for over a week.
You can see that some of the adhesive still has not gone off and the ones that
did go off they did not do a fantastic job of holding the stainless steel.
So you do have to be careful when the manufacturers say that grab adhesives
can stick metal.Yes they can but they don't do it brilliantly and most of
the grab adhesives do work a lot better on other substrates such as concrete
and such as wood. I'd like to thank you for watching this video if you haven't
