Lacquer over latex paint?1/15
I am doing a frame and panel table top. Sapele veneer on the panel and a solid maple frame. I want the maple to be opaque black. I am planning on doing a pre cat lacquer clear over everything. I have read (in Knowledge Base) here that I can use a flat latex paint for the border and lacquer over that.
But when I went to SW and spoke with their technical support, they highly discouraged this. Is that specific to SW brand pre cat?
Alternatively, I thought to use a shellac over the paint as a “clean slate” for the lacquer. Would this work?
Or should I just do a black lacquer?
I don't think any finish supplier would tell you to go over latex paint with lacquer. For the black I would use black lacquer. That is the safest method.
I recently did a distressed paint finish where the piece was stained, painted with a flat paint, rubbed through, thin coat of lacquer, glazes, then another coat of lacquer. Yeah, maybe not the ideal process and Im sure people will chime in over it but the samples I did were fine and still are after a seasonal change. The reason for this process was the client wanted a hand painted(brush stroke) look.
Two options, black vinyl sealer or black precat. Just be sure to sand before coating with clear precat.
Maybe water based lacquer, but definitely not solvent based lacquer. Solvent based will act like paint stripper over latex paint.
General rule of thumb in finishing is to never put a harder finish over a softer one. The other way around is ok, though. I can't think of any finish softer than latex paint.
Further, lacquer is not the best choice for a table top. It ranks low on the scale of durability and resistance to spills.
They used to say you can put anything over lacquer but you can't put lacquer over anything.
I went with black lacquer primer and then black lacquer before the precat.
I also opted to coat after assembly rather than before and then tape off. It worked out well.
