Topic tags/keywords: stain drying time temp humidity

The can of GF warm cherry stain states a ideal drying conditions are 70F and 70% RH. If the temp is 86F and the RH is 37% is the drying time increased or decreased?

Warmth will usually increase the speed finishes dry at, and humidity over 70% will start to hamper drying because there is added moisture in the air. So in your case I’m envious of your 37% Rh.

The age of the finish will also change the time to dry, older finishes get slower to dry, but you can’t know until you can touch it to see how it is coming along.

I always say if in doubt, leave it alone, nothing can queer a project like a finish that isn’t ready.

Decreased significantly. Best to do a rub check with a white cloth to see if it is dry.

Should a rub test result in zero stain on the cloth?

Zero oil yes. Some of the pigment may rub off. Dont have to rub hard.

Have your say...
