Topic tags/keywords: question finishes water based poly spray poly

Many years ago, as water based finishes were becoming available to hobbyists a store gave me a small bottle of poly. I recall that it was off white liquid with a thick part that kept settling to the bottom. I tried it on some scrap and then a small box and was not the least bit satisfied with the results.

Now I find myself with a request to finish a box with water based poly and I am hoping for two things:
1. The quality of water based poly has improved
2. Someone would suggest an easy to use hvlp spray finish that is cost effective.

Any additional suggestions would also be appriciated.

I have been using Sherwin-Williams Wood Classics® Waterborne Polyurethane Varnish. It has worked out well for me both with brushing and spraying HVLP. And if you knew how bad I am at finishing you would know just how good it has to be for me to not mess it up.

I also like it because it is readily available in my rural area. If you catch it on a 40% off sale (which is a fairly frequent occurrence) then it is pretty inexpensive.

If you have other sources available, or don’t mind mail order, there are probably other (and possibly better) ones out there, but this is something that works well and is easy to get.

I like WB poly for lots of reasons, and space and lack of ventilation have pushed me to brushing. Using these quality Gramercy brushes from toolsforworkingwood.com I get results I thought would forever be only from spraying.

The brushes aren’t cheap. But clean readily and are very high quality. I wouldn’t open a can of GF without them.

I do a minimum of 6 coats, two hours between, strain the material for each coat. I sand after two coats and with 500 grit toward the end as needed.

Kindly,

Lee

It might surpise you to know that a great many pros spray Minwax Polycrylic. Its probably one of the only truly very good Minwax finishing products out there. Any home center will stock it. It sprays beautifully too. You might also try Endurovar from General Finishes. Polycrylic can be brushed too as can Endurovar. Stuff you’d have to order but would like: Target EM6000 and Hood Resisthane Plus. Both of these are very much like solvent lacquer but are water based.

Have your say...
