About a year ago I painted the doors and woodwork in my house (interior doors, closet doors, base board, door trim, window trim).
I had birch wood with gloss varnish. Kind of a golden color.
I bought a container of liquid sander and hoped I to use it and avoid sanding and primer coat.
I tried some and it softened the finish and I said to myself “this should work really well because the paint will stick like glue to the softened varnish”.
I painted the woodwork and now a year later am not happy with the results.
I do not recommend using this product. The topcoats of paint have chipped and peeled.
The paint did not stick to the varnish.
Maybe others have had better luck.
I’m going back to the old methods which are to sand the gloss varnish and then apply a coat of primer.

did you paint within one hour of applying the deglosser?
I remember reading the instructions and the importance of applying paint within the allotted time frame.To my knowledge I did apply the paint within the recommended time frame.If I remember correctly I would apply the liquid sander, paint a section, apply more liquid sander, paint the next section, etc.The house is 50 years old and the varnish is probably hard as a rock.^^^^^^

Thanks for posting. Always good to know what works and what doesn't.

I have found a good role for liquid sandpaper is to use it in a tack cloth / rag type fashionlight sand first then clean up w/ liquid sandpaper - should etch / give tooth to your surface
Thanks to everyone for their responses. O was wondering if Others had better luck with the product than I did.Since I was living in the house I was hoping to avoid sanding and stirring up dust.I had also hoped that I would be able to use the liquid sander and then one coat of paint and that really didn't work either.One last thing that did work for me though - I used the small foam rollers and I thought they were really good as a way of applying paint to doors and having a nice looking painted finish with no roller marks and no brush marks.^^^^^^

I've never had a problem with it at all. I do however use a rough towl like a turkish towel with plenty of texture to it and I rub it on real good. Not just wipe it on.
I usually go over the walls with some TSP first which is a cleaner but also dulls the gloss as well. Then I use the Liquid Sand.
Its not a miracle that just takes the gloss off on its own. You have to "work it" onto your walls.If Blodgett says, Tipi tipi tipi it must be so!

I've had real good luck with liquid sandpaper. I've used it maybe three or four times. All of the uses were painting previously painted cabinets that had a glossy finish.
If I was using it on a varnish, I think I'd still use a primer.
Don't know if that would make any difference.

Another day, another tool.
Excellent advice about properly cleaning the dirt and oils from the woodwork.I didn't clean the woodwork with any type of cleaner such as TSP or even soap and water.I may have inadvertently been painting over lemon pledge, murphy oil soap, many years of waxes, polishes, oils, etc etcThanks again.^^^^^^

For years I have used a product called EASY SURFACE PREP for this purpose, and the results have always been perfect. http://www.flood.com/Flood/Products/Exterior/PrepProducts/ESP+Product+Page.htmI have always wiped it on, which will remove most of the surface crud (like any furniture polish, dirt, etc.)I also think a good part of the problem was skipping the primer, which acts like kind of bonding agent to allow your new paint to stick to the old surface.********************************************************

I think your problem was incompatible finishes. The "liquid sandpaper" products work best when the new finish is compatible with the existing one.
Dan, now I'm getting confused (OK, maybe not getting confused ;-). Is the consensus that the liquid sander actually does work (but maybe not on waxed varnished surfaces)?
I take it you've had good results with it?
Thanks.

Varnish and paint aren't (in general) especially compatible. You need a good primer between them.The liquid is useful for "deglossing" and cleaning, and is useful when a primer coat has set too long (most should be recoated within 24 hours or so). It's also useful for repainting with a paint similar to the existing coat, though in that case a light manual sanding (before the liquid) is probably a good idea.
