Hi,
just checked archives without any success. I have a 6' roof rack canvas bag that needs waterproofing properly and am looking for confirmation of the right brand to buy that works.
Can
forum members please pass on the benifit of past experience and let me know what they have used.
My wife was in a shoe store yesterday and bought a pressure pack can of "Silcone
Water-Guard" $19.can blurb makes a lot of salubrious claims!
One can will not be enough I think, but more importantly is using the right product, so I trust you can help.
Regards
Joe

Usually with canvas all thats needed is to wet it and let it dry three or four times,this swells the canvas around seams and the like.Works for tents so should work for a bag.

Hi Nick:
I think it works for tents so long as you don't touch them on the inside when wet, otherwise the capillary action (I think it is) allows
water in. I recall this on at least one occasion when using my tent in extremely wet (tropical grade) weather. During the night my feet were against the end of the tent and I woke up with wet feet and a puddle at the end of the tent. Rest of the tent was fine. But for the duration of my stay the
water kept coming in where my feet had been.
Where is bag is wet and has items in the bag touching the canvas I think he will get
water in.
I have used Scotchguard on a canvas bag I have and it worked fine for me in wet weather. But there are also other similar options.
Cheers
jack

Hi Nick,
The bag is old, but in good condition, and it's been repeatedly wet on travels. The aim is to get a treatment that seals against the internal rubbing action caused by wind buffeting the bag and drawing in
water.

Joe,
Theres stuff you can buy from canvas people for reproofing canvas truck tarps. It looks like runny PVA glue and you roll it onto the canvas and it soaks in. Sure works
well. Makes he canvas kind of tough and a bit unflexible. From memory it is made by Bradmill but Im sure theres others.
Contact an commercial tarp repairer and see what theyve got

Hi Joe, I have used "Bradmills
water proofing compound for canvas" before on the canvas sides of my 20 year old camper van and it works
well.
I used a paint roller to apply it.

This stuff is excellent for waterproofing , but certainly not recommended on new canvas. Its suppoed to reduce it life.
On old canvas though , this stuff is the business.

Hi guys,
Bradmill product not stocked in stores near me.
Spoke with
Southern Cross and they recommended any product that is made for the purpose BUT with a Mineral Turps base will be fine.
They say donot use silicone based types or wax based types as future aplications will not take.
Ended up at RAys "Dry Seal" is turps based
Thanks
Joe
