We spray magnamax thinned down with fast thinner. From time to time we notice that some areas don't dry and cure. We’re using different woods and different types of ML Campbell lacquers. It seems to be something in the prep or wood. A light mist coat over the areas seems to dry it out. Just wondering if anybody ever came across this or has any ideas as to what causes it. We are a refinishing company only. Out process is:
Strip and dip.
Dry for a few days.
Sand to 320.
Seal/stain and three coats on top of MagnaMax.
From contributor G:
Why are you using fast thinner and is it MLC thinner? You should be using standard thinner. The fast thinner is now the same as the economy thinner which is really used for cleaning because it is inexpensive.
- Try a slower reducing solvent to allow the matting agent to flow out more evenly before the coating starts to kick.
- Ensure that you are over lapping 50% on each pass of the spray gun to get even coverage.
- Allow the coating to dry longer between coats to ensure all the tail solvents are out before entrapping them with a subsequent coat.
