Post Cat Finish3/14
I Use ML Campbell Krystal and DuraVar Plus on a regular basis. When I'm finishing a porous wood like African Mahogany, I spend a lot of time with the compressed air gun cleaning the sanded finish dust out of the pores between coats. Sometimes I also wipe the wood with a thin wash of lacquer thinner after the air dusting.
There are hardly any coatings that have true chemical bonding between coats. The vast majority go way past their green curing stage by the time you sand them and recoat.
Matter of fact you would not be able to sand them during the green stage. They would clog the sand paper.
There are no short cuts in finishing. Sounds to me like you are doing it the correct way.
Depending on the product you can spray coat to coat with no abrasion to build the finish. You need a good spray environment to keep the dust from landing in the coats. You also need to truly know the product, which would require you to talk with the technical department of the company that makes your product. MLC has a very good tech dept.
You will get better and more responses in the Finishing Forum.
We fill open grain like mahogany with a slurry of grain filler mixed with the intended stain. The pores are filled. I would not spend the time washing the wood down with thinner or blowing out the pores individually. Wipe it down after a scuff, blow it off and move on.
We use a myriad of finishes from Becker Acroma, Sherwinn Williams, Chemcraft, Gemini, ML Campbell, ranging from precat to post cat and don't experience this.
