I'm spraying (HVLP) some built in dining room cabinets with Benjamin Moore Satin Impervo (waterbourne paint). I've sprayed out some test pieces with 15% XIM extender added and the finish is smooth and flat...looks great. Here's my question: I plan to final coat with General Finishes Clear Poly. Do I sand the final coat of the Satin Impervo prior to applying the clear poly, or apply the poly over the Impervo and then sand before applying a second final coat of poly?
Thanks
Benjamin Moore Satin Impervo is a quality alkyd resin - enamel. It is harder and more colorfast than the poly you want to put on top. Poly is for floors.
Just add another coat of paint and skip the poly altogether. Touchups if needed wil be much easier too.
Scott, I purchased the GF Enduro Clear Poly on the advise of both Jeff Jewitt and the General Finishes rep to use as a top coat for the Impervo Latex Acrylic in a kitchen cabinet application. I thought I'd use the same schedule for the dining room cabinets which are immediately adjacent to where the new painted kitchen cabinets will be.
Below is a product description indicating the Enduro Clear Poly is tougher and more durable than the Clear Acrylic. Also note the GF Clear Poly is advertised as non-yellowing. Perhaps you were referring to another Poly product that is used on floors (Varathane perhaps?).
As for ease of touch up, you bring up a good point. However, I believe the cabinets will be more durable with the Enduro top coat Vs the Impervo top coat. I've been told Impervo would not be the best choice for kitchen cabinets.
It's really frustrating being ignorant about this stuff...I guess I'll learn from which ever way I go :)

BM has both oil based and water borne versions of the Impervo product. The water borne is a 100% acrylic, although they stupidly put the word "latex" on the label because to many folks that means "water borne/water base".Quote:

EDIT: I see that you did say water-borne I missed that, sorry.
I was surprised as anyone to learn that Benjamin Moore has a water base acrylic and calls it Satin Impervo. It's not an alkyd product so it shouldn't be the same name. It really hacks me that manufactures change a product entirely and keep the name the same. It's either Alkyd Impervo or Acrylic Impervo. They both can have a satin finish, but they are not the same.Quote:

With more and more focus on VOC, I suspect that we'll start to see this more in the marketplace as pressure increases to move away from oil-based/solvent-based products.
Probably so, Jim. More pressure based on politics and juck science. When alkyd goes so goes quality. Both in looks and durability.Quote:
