??? about gluing velro to plastic tarp

[Y***@damngood.dog]

Hi,

I want to attach velcro to a plastic tarp, and
want the tarp able to roll up. The person at
the fabric store said sticky back would stick
to the tarp more than to itself. She was wrong.
It comes off much too easily. I don't want it
ever to come off the tarp. What sort of glue
or whatever would be good for something
that rolls up? I wonder about Goop. Also, would
it be better to use a cloth backed velcro that
can soak up the glue, than the rubbery material
of the sticky back type? Can zippers be glued
to tarps like this?

Thanks for any advice or suggestions!

Is it possible to stitch the Velcro to the tarp? Some of the better
made Velcro stuff I've encountered has been sewn to the item.

i wanted to put some velcro on my tarp to hang it to keep from blowing
i used zipties to attach it to the existing gromets i was using 2 inch
wide velcro i would cut a hole in the velcro and then seal it with a
lighter

i was thinking of staples but they would rust

zipties eventually crack due to the sunlight but are easy to replace

zipties are pretty useful if you ever need to attach something through
one hole you can send the leg through then use another zip tie to lock
it then trim the excess

The right adhesive will permanently bond a cloth or plastic-backed
velcro strip to a plastic tarp. Identify the plastics and choose.

Sew it on and then use seam sealer on the attachment points.

Polyetheleyne is very hard to attach to. I probably have used
silicone rtv type 1 with some success. I bought these things
a long time ago from Sportsman Guide. A two piece yellow
ring and hook. With those on both sides of the material, you
push them together until they lock. They can also
come apart and be reused indefinately. I don't have a part number.

Yea I would Sew the velcro on. It is really easy you know you can
handsew it you dont need a sewing maching. I might would consider
getting webbing a couple buckles and making a semi compression set up
to get it really tight.

Someplace there's a web site with a title something or
other like "how to glue anything to anything." It's got
a database of the right glue to attach anything to
anything. If I recall, it also has info on solvents that
will detach many glues without harming, or minimally
harming, the things that are attached. Look on google
for this page, and see if there's something that will
work for your tarp.

There are several types of "sticky-back" hook and pile products. I'm
betting the stuff you used was purchased from a fabric store and used
temporary adhesive. We use hook and pile fasteners in the aerospace
industry and attach them to various materials (fabric, alloys, etc.) and
they simply do not come off. In fact, it is difficult to remove the
material without using the correct solvent. Go to an industrial
electronics supplier and they will likely have the correct product.
Make absolutely sure the material is clean, dry and the coating on the
tarp is secure.

Good luck,

Walmart sells something called "Industrial Strength Velcro". It can be
found in the sewing department and comes as a 1.5" wide by 5-foot length
for about $6.00. Of all the self-adhesive velcros I've tried, this
stuff has the best and strongest all-around adhesive. I can't guarantee
it'll work but it stands a pretty good chance.

It's important to prepare the surface properly. Use 90% isopropyl alcohol
(available from many drug stores) to remove protectants and skin oils from
handling. Sand lightly with a fine sandpaper. Then clean again to remove
the dust from sanding. Allow to dry thoroughly before applying the velcro.
Adhesion will improve over time.

Sharp corners peel up more easily than rounded corners, so round the
corners before sticking the velcro down.

[none2u]

I used the industrial Velcro to glue to plastic sheeting. Like thick garbage
bags. I used staples and a square piece of paper on the other side as a
backing. It didn't look like it was going to stick, but after I let it stick
a week without screwing with it, it doesn't come off.

If it does pop off later (polyethylene is almost as slick as Teflon),
I'd suggest using a nylon tarp instead of plastic, which glue will stick
to better, and to which you can sew the Velcro if necessary.

I always prefer nylon to plastic sheets anyway. A large sewing store that
carries outdoor fabrics should have some very thin nylon that weighs less
than a plastic of equivalent strength, is less bulky, and will outlast it
by a long shot.

For protecting tent floors I suggest a non-waterproof nylon, since you
don't want to trap puddles of water between ground sheet and tent. It's
not necessary for ground sheets to be thick. What matters is that the tent
floor can slide easily over the ground cloth. (IMO far more damage is done
by abrasion than by things poking holes through the tent floor)

I don't don't think there is anything thats a sure hold on it.
i just thought, by making some holes at the velcro
site. Some silicone or polyurathanes can be applied, and
use a backing piece on the other side. The glue will then stick, not
linited to actually sticking to the polyethelene.

Backing on other side, pop rivets, Goop or Shoe Goo to seal any little
leaks?

OK, I had this same problem because I was making sails for home built
sailboats from poly sheeting. I was very systematic about what I tried
and went to several hardware stores buying every type of adhesive I
could. NOTHING WORKED WELL ENOUGH. The closest I came to getting it
to work was to melt it on with a hot iron. Eventually, i went to
polytarp sails that were sewn.

Thanks to everyone for the help! I did get the idustrial strength, but
didn't prepare the surfaces or let it sit for any period of time before
trying it. It has had several days now, and if it still comes off I'll try
Gorilla Glue on it next.
At Home Depot, back by the tarps, I bumped into 7' tarp zippers:

http://tinyurl.com/u4d6r

which are cheaper than anything I saw in WalMart or fabric stores.
Also I thought of a way of bonding things using tape that I haven't
heard about but may be a common practice for some people. The
idea is to use a hole punch and punch holes along the edge of the
tarp and whatever is to be applied...like the sides of a zipper that
could be sewn to it. Make it so the holes line up so you can see
right through both objects where the holes are, and then run a
strip of tape over the holes on both sides. Where the holes are,
the sticky parts of the tape will stick to each other and should have
a very strong grip at the points where it does so. Punching holes
in the tarp behind the sticky back of the velcro, and then running
tape over the holes to stick through to that might work too. I'll
try it on some scrap to see.
One more thing I learned is that gaff tape works a *lot!* better
on a tarp than duct tape does. Gaff tape is some awesome stuff
for several reasons.

Tarp zippers are the bomb, I didn't know about them either until I did the

No, but I learned that gaff tape will hold tarps together and will also
hold clear plastic windows in them. Then learned about the tarp zipper,
again re-inforced with gaff tape. The only real problem I was having
was with the velcro, but I finally figured that out too :-) Using one inch
sticky back industrial strength velcro I traced out where it would go on
the tarp, then took a hole punch and punched holes in the tarp behind
where it would be about 1/2" - 3/4" apart, making two rows of holes
along the length of it. After sticking the velcro to the tarp, I stuck gaff
tape on the other side so a good bit of sticky parts of tape and velcro
stuck together through the holes. Now the velcro doesn't pull off the
tarp any more.

Tarp zippers are the bomb, I didn't know about them either until I did the
Velcro thing...

I've found the velcro to be useless as velcro. It holds things together so
far, but if I take it apart a few times it won't stick to the tarp any more,
so I learned that as far as I can tell sticky back velcro just won't work.
I tried using Gorilla Glue along with it, and that makes it even worse...
the glue forms a thin hard sheet which doesn't stick to the tarp, and which
also destroys the stickiness of the velcro. It just sux.

I want to attach velcro to a plastic tarp, and want the tarp able to
roll up.

Someplace there's a web site with a title something or other like "how
to glue anything to anything." It's got a database of the right glue to
attach anything to anything. If I recall, it also has info on solvents
that will detach many glues without harming, or minimally harming, the
things that are attached. Look on google for this page, and see if
there's something that will work for your tarp.

There are several types of "sticky-back" hook and pile products. I'm
betting the stuff you used was purchased from a fabric store and used
temporary adhesive. We use hook and pile fasteners in the aerospace
industry and attach them to various materials (fabric, alloys, etc.) and
they simply do not come off. In fact, it is difficult to remove the
material without using the correct solvent. Go to an industrial
electronics supplier and they will likely have the correct product. Make
absolutely sure the material is clean, dry and the coating on the tarp is
secure.

Walmart sells something called "Industrial Strength Velcro". It can be
found in the sewing department and comes as a 1.5" wide by 5-foot length
for about $6.00. Of all the self-adhesive velcros I've tried, this
stuff has the best and strongest all-around adhesive. I can't guarantee
it'll work but it stands a pretty good chance.
It's important to prepare the surface properly. Use 90% isopropyl alcohol
(available from many drug stores) to remove protectants and skin oils from
handling. Sand lightly with a fine sandpaper. Then clean again to remove
the dust from sanding. Allow to dry thoroughly before applying the velcro.
Adhesion will improve over time.
Sharp corners peel up more easily than rounded corners, so round the
corners before sticking the velcro down.

Thanks to everyone for the help! I did get the idustrial strength, but
didn't prepare the surfaces or let it sit for any period of time before
trying it. It has had several days now, and if it still comes off I'll try
Gorilla Glue on it next.

which are cheaper than anything I saw in WalMart or fabric stores.
Also I thought of a way of bonding things using tape that I haven't
heard about but may be a common practice for some people. The
idea is to use a hole punch and punch holes along the edge of the
tarp and whatever is to be applied...like the sides of a zipper that
could be sewn to it. Make it so the holes line up so you can see
right through both objects where the holes are, and then run a
strip of tape over the holes on both sides. Where the holes are,
the sticky parts of the tape will stick to each other and should have
a very strong grip at the points where it does so. Punching holes
in the tarp behind the sticky back of the velcro, and then running
tape over the holes to stick through to that might work too. I'll
try it on some scrap to see.
One more thing I learned is that gaff tape works a *lot!* better
on a tarp than duct tape does. Gaff tape is some awesome stuff
for several reasons.

Gaff tape sounds like good stuff..

When I place a geocache using velcro I always use glue in addition to the sticky
stuff that comes with velcro.

I think the suggestion to get out your sewing needle and then seam sealer is the
best. Think about it, tents are not glued together.

No, but I learned that gaff tape will hold tarps together and will also
hold clear plastic windows in them. Then learned about the tarp zipper,
again re-inforced with gaff tape. The only real problem I was having
was with the velcro, but I finally figured that out too :-) Using one inch
sticky back industrial strength velcro I traced out where it would go on
the tarp, then took a hole punch and punched holes in the tarp behind
where it would be about 1/2" - 3/4" apart, making two rows of holes
along the length of it. After sticking the velcro to the tarp, I stuck gaff
tape on the other side so a good bit of sticky parts of tape and velcro
stuck together through the holes. Now the velcro doesn't pull off the

Properly called Gaffers Tape..its a version of the umbiqutious 100 mph
tape or real high quality duct tape, designed to be applied, then be
removed.

Its rarely found in hardware stores. Its a specialty item.
http://search.ebay.com/search/search.dll?from=R40&satitle=gaffers+tape

I'll call it duct tape. I have been using the green stuff sold by Sportsman guide,
and I have taped a home made fly for my tent using this stuff. Still holding after some years.
Its also called airplane repair tape. I have also tried Gorilla Tape, but the ducts up
in the attic, have made the tape not stick very well to aluminum. I,m not
convinced of the overall quality of this tape. Time will tell.

I can't find the good tape on their web page, but have others. The green stuuf is able
to stretch, which makes it unlike others. I would search for airplane repair or 100 mph tape.

This seems like a real good price if its the real thing.
