Hi folks, I am doing a redo of a old microwave cart by placing a oak piece on top. I have placed 3 coats of oil based poly and it is turning out well. Can anyone recommend a proper cure time that should be allowed before setting the weight of the microwave on it for daily use? I would hate to damage the appearance of the Oak by using it too quickly. I know dry times and cure times vary greatly. Thanks in advance.
Hi mrs.Rita most poeple would say 6 hour's but I let all my project's set for 12 hour's I know it's a long time but it's batter than a fly paper project.But thats my 2 cent.
I’d suggest waiting 48 hours, before putting it to use, as you've described.
The appliance likely has 4 small diameter feet or spacers made of rubber or plastic.
The pads will leave imprints into soft material, such as poly or the like, thus the reason for longer cure times,
I’d place a furniture type leg pad, 2- 3” diameter, under each foot. The larger foot pads will distribute the weight over a larger surface area.
Rubber type foot pads are more resistant to slippage over the plastic pads.
Drying and cure times are affected by temperature and humidity.
I would say at least 24 hours. I think that is what my can says. But humidity makes a huge difference in dry times. I'm in the south so the longer the better!
Thanks guys! I'll admit, a little surprised because I was certain I would hear suggestions of perhaps a week or more. I knew that you could recoat in a matter of hours but I thought it needed much more time to reach a level of protection. Temps have been warm with low humidity, rather perfect actually. I placed the last coat on Tues so I should be ready to go. Thanks again!
you are probably used to hearing the cure times for varnish used on flooring which is normally 30 to as much as 60 days, especially to put rugs on or heavy furniture. for furniture, mainly table tops I have always waited a minimum of 48 hours for use. you can tell the amount of curing by the smell. the smell is a result of the chemical reaction taking place as the varnish cures, the longer it sets, the less it smells. when making something for a customer I normally try to wait 4 to 5 days because most people don't like the varnish smell in the house. to me, the smell of laquer is better than any scented candle, or better yet the smell of fresh cut oak, cherry, or walnut.
Thanks Mandodad. Have the top in place and in use. So far so good and I am liking the way it has brought new life to the piece. I guess that is called upcycle. Works for me :)
