The house we moved into has an old tanning bed that was made in 1989. I’m wondering if I can use it to speed up the drying time on finishing; like polyurethane or gel stains. If so, what would be the best way to set it up?

it’s heat, not light that finishes rely on to “cure”; most finishes need some sort of evaporative process to remove the solvent. UV light exposure causes aging/weathering/fading and finish degradation which is what most of us are trying to avoid by finishing our projects!

Sounds like a really good way to ruin your finish in a hurry. Most finishes attempt to protect wood from UV rays. I bet a tanning bed would really bypass that and directly damage the wood. On the other hand if you wanted to distress a finish to make it look old there might be an application. It would take some serious experimentation, to get the right look w/ different finishes.

Short answer is “NO” it probably would do more harm than good.

The “OTHER” answer is you can work on a really KILLER TAN while your project is drying! :-)

Beside all the above, you’ll give your project skin cancer.

I wouldn’t chance it. Doesn’t sound like even drying. Start another project while it’s drying.

Some woods, like cherry, develop a natural patina with exposure to sunlight. I wonder if you could use the UV lights from the tanning bed naturally darken cherry, redwood, and possibly other woods PRIOR to finishing them. May be worth throwing a few boards in there to see what happens.

Perhaps useable if you are using stuff like this: http://www.woodgears.ca/wood_grain/uv_finish.html

While it’s tanning grab the wifeys curling iron. They work awesome for evaporating paint thinner out of a freshly cleaned brush. I won’t even clue you as to the abilities of a blender or dough mixer….especially gear reduction models from Kitchen Aide.

Thanks alot for your replies and advice. I was having a bit of a brain fart when I asked this question. Thinking that the tanning bed was putting out as much heat as it was light. The situation I’m in that brought up this question was that the weather is getting colder and I have a ton of projects to urethane and stain before Christmas and I’m trying to figure out a fast way to get my work to dry. I’ve set up my garage pretty decently for a workshop but it can be a trick to keep it warm in the winter time with my kerosene heater and worry about the possibility of a flash flame from the fumes.

It would probably darken cherry, though…

Some industrial lacquers are UV curable but I don’t think it will work for off the shelf products. A small fan heater might suit you better though not pointed directly at your piece.

Martin, I was having trouble getting my finishes to dry in the garage workshop. Lacquer that ought to have been ready for another coat in 1 hour was still tacky after 3. I set up a small fan in one corner and got it to create some circulation (no added heat). Viola! Cure time back down to what the label said it ought to be. A little air movement might be what you need.

Don’t know if it’ll work, but I’d be afraid my work would look like George Hamilton!

NO, and your wife/ girlfriend / significant other might be upset you re-purposed such devices. (laughing)

I wonder if you could tape down masking patterns to UV-sensitive wood then use the tanning bed to darken the rest. You could make leaf patterns in padauk or something… might look neat.
