Are all CV's the same requiring upper 60's to cure properly? How long must that temp be maintained? Besides pot life and adding catalyst, is there anything else I need to know about CV, (as I have been using nitro for years)? Are there any differences among brands other than price? (Finishing oak for restaurant with airless).
From contributor B:
Upper 60's temp is ideal, but I've used CV's anywhere from 40's-90's and I've never had a problem. Main difference between lacquer and CV is it is harder to do touch-ups. CV is much tougher by nature so itís harder to blend in and what not. Also, when applying multiple coats, lacquer melts into itself forming almost one thick coat. CV does not have this melt-in property, so the only form of adhesion you get is through sanding and creating scratches for the next coat to grab onto. As far as I know there is no recoat window. It must be sanded in between every coat.
The threshold was 68 if I remember correctly and at the time was not provided in the data sheet. A failure occurred as a result and I had to strip a few mahogany tops and start over- it could have been worse. Based on my experience with this product I would recommend taking the temp threshold seriously, make sure the ambient temp and the material temperature is well above the minimum.
