in this video I'm going to test out some more common grab adhesives or
construction adhesives, I actually have eight or nine different types this time and I've
actually tried some of these in the past so there are other videos available
showing some of these adhesives this time I've actually bought some of these
this which have been recommended by the viewers on YouTube so some people have
recommended the adhesives I've gone out bought them we're going to test them
we're going to do three different tests in the first test we're going to stick
some stainless steel box section to some sheet stainless steel and then measure
the force required to separate the pieces using a hydraulic ram and the second
test we're going to test the grabbing power by sticking some block pavers to
a plasterboard petition I must point out that some grab adhesives do recommend
that anything stuck to such a surface should be propped until the adhesive is
cured if you are wondering why I do this test is because of a video that used
this exact test but gave biased results towards the manufacturers of
the video it is getting very expensive now doing all these tests and there is
quite a lot of work involved in setting them up, so this will probably be the
last test for a while all these stainless steel test pieces
have had a label attached and I'm gonna put the corresponding grab adhesive on the
stainless steel and then glue that down these have all been cleaned on the back
using methylated spirit and in each case I'm going to try and put a similar
amount on each piece of stainless
I'm going to turn that over and then I'm going to glue that down in position
I've actually got halfway down the tube now there's nothing come out of that well
I'm afraid that one's a fail I can't actually get that out it's gone to about
there and then we can't actually get any of the product out I have actually pierced it
with the screw in the end there but it just won't come out this is the PL
premium I actually had to transfer this into a regular sized silicone tube
as the tube that it came in was huge
I'm now going to speed things up a little
for some reason that's not coming out very well
try it again it works that well it's obviously glued the end into the
cartridge
I've got a little bit coming out of the end there so as you can see the product
is still soft but we can actually get it to come out of the tube obviously it's a
bit disappointing the tech 7 never worked we couldn't even get that out
the tube because that was 15 pound this one was a lot cheaper this was about
three pound but I can actually feel that that one is completely solid I
suppose that is one of the disadvantages of putting it in a
cardboard tube so we can definitely write that one off I want to try and get
some of the tech seven out of the here I'm going to actually put it in a new
cartridge that way we can test it out at least then we've not wasted the 15 quid
these blocks have had well over two weeks for the adhesive to cure
I'm gonna start off with the gorilla grab adhesive I'm then going to push that
onto the board now I'm giving it a really good push and with a slight
twisting motion and I'll try the HB 42
now the PL premium now the new improved adiseal and the last we have one
that's not actually slid right off just yet!
well just apply the next one which is PU
18 now the super bond and then finally I'm going to try the saves nails
so the only two adhesives that actually stuck out of that test where
the Superbond which is done really well that's only slipped a small amount and
the Adiseal the Adiseal has slipped considerably but it is still stuck to
the wall we'll now do the grab test with the
Tec 7
obviously that has slipped down considerably but it has still stuck it
to the wall I've now glued these blocks of hard
wood onto this stainless steel this is 316 stainless I did
actually put all these on at the same time and then I did actually have to move it
out of the way so the saves nails has actually creeped a bit
backwards so like that's this slid back none of the others actually moved but
for some reason that one has moved these blocks have had well over two weeks
for the adhesive to cure
that one has finally failed and we do have a bit of a hydraulic leak on there now we've used that much pressure
well, I think we can quite safely say that that one is firmly stuck and I
do have hydraulic fluid leaking all over the place here so as you could see the
Adiseal is quite firmly stuck to that stainless steel the stainless steel
actually screwed down to the timber and it's actually started to rip the screws
out of the timber so there was no way at all and that was actually gonna budge so
that is stuck extremely well that is actually unbelievable I'm I'm going to
test out the final one which is Tec 7 hopefully the hydraulics will hold up
enough just to do that because it does now like the seals are now passing in
the cylinder so there we have that test I think the clear winner there was
definitely Adiseal so I've done a few different tests there there's no overall
winner but there is a vast difference in the price of these products hopefully
this has helped you to choose one of the better ones which is not necessarily
always the most expensive
I will put all the results in the description I do hope you've enjoyed
