Continuing the project of varnishing the exterior face of a mahogany entry door.
Is going well - better than I would have expected, certainly the result of all the helpful guidance from members of the group - with special thanks to DadiOH.
The first coat of Flagship varnish was thinned 10% (per manufacturer's instructions) with their T120 brushing thinner and went on well for my first time applying varnish and to a vertical surface.
The product tech bulletin states time to dry hard is 8-12 hrs @ 90 F.
Four days after application there were areas where the varnish had accumulated that were still very gummy / tacky - note our max. temps have been in the mid to upper 90's. The accumulation was approx. 1/32 +/- thick.
Thinned to the max. recommended - do not understand why this would be the case.
Should remaining coats be similarly thinned or applied with no thinner - although may need some considering the temperature.
Best time is late afternoon when the humidity is below 50% - of course that is when the temp is at or near max. for the day.
Thanks again for all the great advice!
