Topic tags/keywords: finish cure dry time general salad bowl fast quicken speed

I have a couple of projects I’m putting SBF on, and would really like to speed up the wait time between coats. I have the ability to put a shelf in my clothes dryer, and run it on low heat, or no heat at all (just circulates air). Would this help? Is there any downside to doing this? Thoughts?

Heat and circulation will decrease the cure time somewhat. If it were me however, I’d be patient and let it cure at room temperature. Next time you’re in a hurry, choose lacquer instead.

A warmer environment will speed up the curing process. If my shop is on the cool side I usually bring the work into a solarium off our family room where it is much warmer. The clothes dryer is an interesting idea. I think I would let the finish sit for an hour or so before heating it up.

The only down side I see in speeding things up is that if it cures too fast the finish may not have time to level out smoothly. I usually apply the salad bowl finish with a piece of high quality paper towel. That way I can just throw it away instead of trying to clean a brush. A lint free cloth works too. Wear gloves to keep it off you hands.

If you are trying to get a faster build up you may want to try Behlen’s salad bowl finish. I find it goes on much thicker than Generals. I usually apply 3 coats of Behlens but use 4 coats of General.

I’d be afraid that your clothes will smell like the finish for a while so I wouldn’t do this. I think you best bet would be warmer spot and plenty of air flow. I tried that finish (now called wood bowl finish) recently for the first time and personally I was not impressed. It works well enough but I don’t like the 24 hour cure time between coats and it smells unpleasant. If I have to wait that long between coats anyway, I like Tried and True varnish oil better.

I find I get best results by not rushing things. Is there a reason you are trying to speed it up? or just antsy? What is the temp and humidity where you are/ When I do need to “rush” I’ll use a hair dryer, or bring a space heater into the garage to get the whole garage warm and dry. I’d personally avoid the clothes dryer thing, I don’t want to end up on the news.

By rushing it, you will run the risk of a gummy finish, you will then have to strip it off to correct and then start all over. That will take much longer. Go slow, it’s faster.
