Teardrops n Tiny Travel Trailers

Ok I plan to re cover the Duck tape tear after our January gathering with canvas and was wondering what temp is good for glueing the canvas to the outside. I am working in a garage but it is unheated I have plenty to do inside the camper with inlarging the bed, adding built in cabinets and paneling so I won't be doing the out side till closer to spring.

I have not had any problems using TB2 down to about 45 deg F. I think on one occasion I pushed it to 40 deg F, but would be reluctant to go any lower than that for fear that the temp would drop after I left the shop (after shutting off the small portable heaters and Coleman lanterns, and usually with evening temps approaching fast).

Yesterday the shop started out at 32 deg F (freezing) with outside temp of 25 deg F. I did other things until the heaters brought it up to 45.

Today the morning temps were in the teens with no relief in sight, so I left my glue and polyurethane at home.

One thing clearly stated on the TB2 bottle is “Keep from Freezing “ ...

Yes, and if you do your homework you will find that they don't recommend using it below 50 deg F. (I forget if that is on the label or something I found on their website.)

edit: ... or maybe that was for the GG (???)

WIth PVA glues, there is something called the "chalk temperature." This is the temperature at which the glue turns white and has dramatically reduced strength. It has to do with how the moisture leaves the glue during its curing process. For most PVAs this is between 45 and 55 degrees. Relative to the adherands, the temperature of the glue has much less effect because the thermal mass of the adherands. In simple terms, this means the temperature of the wood & canvas is more important than the temperature of the glue.

I've got a whole folder of technical information from a day-long Titebond seminar I went to if you really want to geek out on glue.

Strictly speaking from experience, the more humid the longer it will take TB II to dry.

No plans to work in freezing me and the cold aren't the best of friends. So I'm probably looking at March around here that will leave me enough time to finish before May's gathering.

January thaw, Indian Summer?????

Its what I'm planning for to finish assembly.
At least thats the current target.
