tarp repair glue?
 

Hi all!

Is there a glue that will work on polyethylene tarp material? Often
I'd like to make patches to secure rips so that they don't get larger,
but no glue I've tried seems to "melt" the tarp material to
form a good bond.

Is there a glue that will work?

thanks!

Don't know about a glue, I haven't found one either, but Harbor Freight
Tools has a tape that works about as well as anything I've found.

Hi Jacques!

Contact cement - good idea. I'll give it a try.

"contact" cement is also called "rubber" cement

people who make polytarp sails also bond by heating with a hot iron.

.... and will pull apart with very little stress. Polyethylene is notorious
for having a surface that nothing will stick to. You can heat weld it, but
it's beyond most non-commercial applications. It takes specific heat,
pressure and dwell times, done either by bar sealers or "doughboy"
continuous band sealers. You can try any glue you want, but I can tell you
from years in R&D in the plastics industry, there is nothing that will work
well with PE. Best bet are those tapes mentioned earlier, used on both
sides. Duct tape will for for a few weeks, but weather and UV will tear it
up pretty fast. Really... those blue poly tarps cost what... $5-15? Replace
it if it's gone!

Nothing that's not a lot more expensive than the tarp. However, there's
always duct tape.

double sided carpet tape is also used in making cheap tyvek and polytarp
sails. I haven't used it myself but from what I've read on the Internet
its reinforced with glass fibre and is very strong. It might be ideal for
applying patches where tape alone won't do.

It all it was, was a blue poly tarp I would just replace it.

But it is not. It's a 33 foot by 20 foot piece of 6 mil clear poly
that I use as a roof on my boat shelter. It works great as a
"greenhouse", and to be honest, I dont' feel like replacing it because
of one tear. But if I don't deal with the tear, it will get larger.

How long has it been up? Regular 6 mil poly is not going to last more
than 6 months to a year in the sunlight. Any repairs on old sheets is
wasted effort. I suffered with it for a couple of years and then went
to real greenhouse film. It has been up for over 3 years now and is
still just as strong as new. It cost about 3 times as much as regular
builders 6 mil poly but it will last 4 or 5 times as long and you are
not faced with the hassles of replacing it.

I can't remember the brand name. That happened in Haiti 25 years ago and I
used some german contact cement that I had on the boat.
It worked relatively well but I remember that we had to press the glue line
down under a 2x4 then hit with a hammer . . . all fine sailmaking skills . .

It's not like this is the first time I've done this:

I've gotten pretty good lifetimes out of this stuff in thw
past. This is because in the winter what sun we do get is low angle.

And in the summer, I cover the clear plastic with a white tarp to
reflect the sun off the shelter/boat. So the harsh summer sun is not a
factor in breakdown of the clear plastic tarp.

However, as I wrote in another note, the production qualityof this
stuff has fallen off severely. So I might be interested in a substitute.

Do a search on "Greenhouse coverings".

What I used is Tufflite IV made by Tyco plastics. I got it from Parks
Seed but they are wholesale only. Search for Tufflite or AT Plastics
Dura-film. It is not cheap. 20' wide cut lengths of Tufflite are about
$2/foot and a 100' roll of Dura-film is about $150.00. Maybe someone
else here with a long term project will split a roll with you.

If it has only been up a month you may as well duct tape it closed and
wait until next year. Better yet is Poly-patch, a tape made for
patching poly greenhouse film. The patch will last longer than your
cover. Try B&T Growers supply. They have 2" wide rolls for about
$10.00. Thye also have Dura-film.

Try some weathershield clear tape available at Walmart, the stuff you
get in the winter insulation isle. It looks like packing tape, but it
is not the same, it is stretchy a little so it gives and holds real
nice. We use it to repair plastic weather sheeting all the time, it
holds up as long as the plastic if done properly. Put a layer on each
side of plastic, along the tear.

Yea, search for greenhouse film. Monsanto makes it, as do others. It uses a
nickle UV inhibitor that will give it a reasonably long life, as long as
it's installed properly. If the clear plastic has a greenish tint to it, it
has nickle UV inhibitors in it. If it's clear, it doesn't. Regular poly has
no uv inhibitors, and will crack up in less than a year, especially clear.
The best UV inhibitor BTW is carbon black, so black plastic will last the
longest. White plastic will cut down on the transmission of UV to whatever
is underneath it, but will still allow some. The pigment is titanium
dioxide.

Well no need to worry about repairing rips inthe tarp - this weekend's
Nor'easter took car of the cover.

So now I have to get more plastic. There's the Greenhouse film, but
that seem slimited to 6 mil. I was wondering if there was another
source of clear poly plastic that's thicker than 6 mil.

Jamestown also sells clear ploy with a weave in it to resist tears. I
might try that.

Black will last a lot longer, if the heat isn't a problem. That clear woven
stuff will be OK for a few months, but will still degrade in the sunlight.

Black isn't optimal because it doesn't let the light in. Makes the
interior of the boat shelter very dark even on the sunniest of
days. And that's year around.

In the summer, the black tarp would make it unbearably hot.


That clear woven
: stuff will be OK for a few months, but will still degrade in the
sunlight.

I manage to extend it's lifetime by putting a white tarp over the
clear in teh summer. This wards off UV degradation and also reflects
sunlight enough to keep the interior of the shelter much cooler than
in sunlight.

In winter the clear plastic is exposed to the sun - what little we
get of it. And the angle of the rays of the sun is much less in the
winter.

I've had clear, non-UV protected, poly last several years - so long as
snow loads don't destroy it.
