TGIF: Cold weather finishing

Rate this topic

Recommended Posts

Here is an article on cold weather finishing.  Note that it is supplied by a vendor so they lean toward their product.

 

Remember that finishes "cure" by one of three methods

  • Evaporation of the solvent (spaghetti) lacquer, shellac, and wax
  • Chemical reaction with oxygen (tinkertoys) varnishes  (that also contains a dilutent that evaporates off first) and oils
  • Bonding of large molecules that have been softened (soccer balls) water borne

 

The first dry fast (minutes) but to fully cure take a bit longer, the second and third get solid in a few hours, but can take up to 21 days to fully cure.

 

Note that most chemical reactions double their speed with every 18F (10C) rise in temperature, conversely take twice as long when temperature drops, or may stop completely.

Well that explains a few things.  Basically this paint is probably not going to work for me?:)

Just Saying,

Who We Are

Operation Ward 57 Challenge Coin Display Project

We are a woodworking community with an emphasis on sharing and learning the skilled craft of woodworking and all of its related disciplines. Our community is open to everyone who wishes to join us. We support our American veterans and active duty, being a veteran is not a prerequisite to join. Join us now!

Objective

Air Force Command Center Plaque

Of course just like most online woodworking communities we are centralized in the arts, crafts, and trades that are woodworking. But, we have another focus in our Patriot Woodworker community, we are the only woodworking community that was founded on our care and concern for our disabled veterans.

Volunteer

Patriot Woodworker Volunteers

The Patriot Woodworkers are an all volunteer community, from the staff and hosts who run our online woodworking community to the members who frequent our forums, you'll find volunteers in all of us. We are not on a payroll, unless you consider the spiritual rewards gained from volunteering, as compensation.

Education

Logging

One of the many projects we are working on is a wiki for our online community. A wiki is a great way for woodworkers and enthusiasts to share their knowledge to others, and to impart their knowledge for others to learn from, and utilize as well for their own benefit. We hope you'll consider being a wiki contributor.
