I painted all the doors in my house with this product - it's a water based product that levels like oil based - and it worked really well. I had no brush marks at all.

Most of my trim I painted with the standard BM latex product. There was one piece of doorway trim that is about 7" wide, completely flat that I wanted to paint without brushmarks. I had a half quart left of the Satin Impervo that is a few months old. Right away when I started painting it I noticed there was a lot of brush drag which I had never noticed with this product. I had to fiddle with it too much and of course I ended up with quite a bit of brush marks. I'm thinking that this product degraded quite a bit in the 3 months even though it was only a half full quart. Is this possible? Can lid was tight but it just did not behave as it did when I painted a dozen doors.


The perfectionist in me wants to do this over however I have tried to coarse sand latex paint in the past and it was no fun. Since the paint is still fresh I'm thinking it may come of fairly easy especially since it's a totally flat surface. The paint underneath was sprayed and is relatively hard so I don't think there is much danger of going through to bare wood or MDF. In fact I could use an orbital sander on this. What are the chances that I will create an even bigger mess?


I also wanted to ask what you do if you want to get rid of all the old paint on interior house trim because the existing paint is too thick and/or was poorly done. Do you use stripper? Can the stripper damage the adjacent drywall?

Thanks

I've used the Latex S.I. alot lately and I've noticed that it behaves alot like oil
if it sits in a can for any amount of time it will need to be thinned, you can use water or floetrol, http://www.floodco.com/Products/floetrol.cfm

As for the re-coating, you might want to let the paint cure for a few days then you can sand with a 150 grit sand paper until smooth, if you sand too soon it will dig into the paint making a bigger mess.

Paint removal: mask off the walls with blue tape, it should help, if you don't then the stipper will mar the wall paint, the stripper will start to break down the adhesive on the tape, but this is ok because it is better then removing the paint from the sheet rock. You will most likely need to re-paint the walls.
If there are multiple coats of old oil you should get a "Marine grade" semi paste stripper (this is a chemical stipper please read all cautions and directions) you can apply this with a brush, and if the paint really has a grip cover the stripper with aluminium foil to keep it from drying out before it has a chance to soften the paint.

Hope this helps

Yeah, it definitely thickens over time. I wouldn't use water myself, it never seemed to really mix in well. Floetrol would be my first choice. And you also need to shake the can a lot, aggressively.

Also an old timer showed me one time when you close the can up for storage, blow into it as you cap it off, forcing out the oxygen and replacing it with carbon dioxide. I'm no chemist, but it does seem to work.
