I just finished varathaning a project and it dried to a chalky-white. It looked good when i put it on, and now, it dried to a chalky white.
Why?
Does anyone have any suggestions on how to fix this?
Thanks

i believe what you have is moisture in the finish. this can happen if it is a relly humid day or it drys to fast and traps the moisture inside [sometimes sitting something in the sun will dry it to fast]. i would scuff sand it lightly and put another coat on it,it should be ok then larry
hand me the chainsaw, i need to trim the casing just a hair.
Now i have finshed a second coat and as it is drying it seems to be getting chaulky again.
Yesterday was pretty humid, but all night I left the heat and fan on to dry the room out.
I'm thinking about covering the finish with a linsead oil!? What do you think?

i can't really answer about the linseed oil,i would think you would have to strip to bare wood to make it work . larry

Will be interesting to see replies.
Have used probably close to 50 gallons of polyurethane of various brands over the years, a few even were Varathane brand. Most were oil based, never had the problem you describe.
Have had "satin" finish look cloudy due to using an old can where the 'satin' filler did not mix well, never anything I'd describe as chalky.
Can you post a picture?
What stain on what wood was it over? Probably no difference if the 2nd coat did the same.
Was this an old can that had been left 1/2 full for a number of months?
What was the stain? How long did it dry before you Varathaned over it?
Bump,
Have never personally seen the condition described in the original post -- anyone????
I have - using oil based stain and then applying a waterbased poly too soon. The stain needs at least 24 hours to evaporate.
