What glue to affix velcro to canvas?

Hi Grassparot

You don't say what type of Velcro so I will assume the woven type (not sticky back stuff)

The woven type has an elastomeric binder coat which locks in the hooks and loops in the ground weave and so most commerical glues don't work well with it.

Hence they reccomend sewing, or at least starting with the adhesive backed stuff and hand sewing a few points to help it hold.

I'd take a little hand sew kit and sew it when you can.

No glue will provide a bond strong enough to achieve what you desire.
That's why they are sewn in the first place.

I wouldn't risk contaminating the canvas and potentually destroying its waterproof properties.

My tip is to do without the awning "one more time" and have the velcro sewn on at a more convenient time.

You need cotton glue, apply liberal amounts using a needle or a sewing machine!!!!

Grass Parrot, Give Doug Smith a call on 8586 3647. He works from a shed near the pub on Para Street. He might be able to squeeze you in. He is Gus' brother if you knew him.

I reckon that the advice on sewing is the best, but one product I have used on canvas is worth a mention. There is stuff in a tube called "Shoe Goo." You use it to build up new soles on worn shoes. Waterproof, tough and flexible when dry. I have used it successfully on a number of repairs to tents and waterproof jackets. I'd be inclined to use some and sew it as well.

Hi Grassparrot

You might laugh but I have seen Velcro Stapled as a temporary
solution,

There is an industrial type glue used by Motor Trimmers and Upholsterers.

I recently had a canopy built for my trailer and the Upholsterer forgot to put the velcro strips on to Dacron type material. He then glued them on and they are stuck fast. Seeing same fella this afternoon and will ask for the name of the glue.

Cheers

Grass,

If you are gunna glue it, try Selley's Liquid Nails. I know its a woodworking adhesive, but we used to use a similar type glue, back in the BTEC days, to stick back tags onto cattle.

It used to stick like the proverbial!!!!!!!!!

Have a good holiday,

Hooroo,
