A while back I did some tests using some popular grab adhesives. I'm now going
to repeat that test because quite a few people were suggesting other makes which I
didn't actually try in the first video. So I've now got about six or seven
different types. We're going to do two tests the first test is going to be an
initial grab test on this plaster board and to do that we're going to use some
block pavers. So we're going to see what the initial grab is like on a
vertical surface like that. After we've done that we're then going
to do a test where we glue some blocks down onto a piece of wood we will then
test them out using an hydraulic test rig and see just how much force is
required to break the bond between the two pieces of wood. These are the seven
grab adhesives I'm going to use we've got CT1, Gripfill, Adiseal, Serious Stuff,
The Works, No More Nails and Pink Grip. We are going to start off with the No More Nails original.
So I'm now going to run four beads of adhesive
and then I'm going to take that and I'm going to push it into position
on the plasterboard. I will push it on there as hard as I can.
and then you can see that it does look like it's actually sliding down quite a bit.
I'm now going to try the Pink Grip and again I'm going to push that into position.
I'll push that on there as hard as I possibly can
and the initial grab on that does look pretty good it's not actually slumped
down at all. Now Geocell The Works
and again that does look like it's got a bit of creep on it. It does look like it is
sliding down slightly. Now the Adiseal.
So I think we can safely say that the initial grab on that one isn't all that good.
Now the Grip Fill. The wall isn't looking too good at the moment we do have the
Adiseal and the No More Nails that have slipped down considerably. Now for the Grip Fill.
That one just isn't holding at all it's sliding straight down the wall.
Now the Serious Stuff.
You can see that just isn't holding at all.
So I'm just going to move that before it falls. Now I'm going to try the CT1.
I'm now going to push that into position.
So I have to say that the initial grab on all of those adhesives was not all that
good especially considering as some of these are nearly £10 a tube.
The only real one that has successfully stuck without moving very much is the
Pink Grip and surprisingly that is one of the cheapest adhesives that I've
actually used in this test. The CT1 does seem to be holding now although it
did slip down considerably. We're now going to do the second part of the test
so on each test block I have put the label. I'm going to put the adhesive on
that and then I'm going to screw it down in that position
using the drill through the two holes, then after the adhesive has set after a
couple of days, we'll remove the screws and test the amount of hydraulic
pressure it takes to remove each block.
