wanting a smoother paint finish

Post by Mpmarvin » Thu Oct 05, 2017 7:59 pm

Got a question guys. I tried my hands at painting. I'm getting a finish the wife is not feeling

As you can see in these photos I have a lot of ripples. I used these to apply the primer

And I use a foam roller to apply the paint.
But this is the result I'm getting. The wood I'm using is a birch veneer plywood. At least I believe it is. I sand it down on the palm sander from 60 to 120 to 220 grit. And feels smooth but I guess that's in comparison to what it feels like before sanding.

Any help guys would be appreciated. Wife doesn't want any of those ripples.

Here's the blue. Same thing

If you want a very smooth finish I think you probabably have to spray the paint rather than using a roller.

Thanks. I was talking with the wife and that's exactly what I thought you guys were going to say.

That is exactly what you will get with a roller, regardless of foam or nap. IMHO, foam rollers are worse because they aerate the paint as it is applied, creating even more bubbles and bumps.

If you lay the paint off with a brush, you'll have long lines instead of the orange peel texture of the roller.

The only way to get a reasonably smooth finish is spraying. You can add flow additives to the paint that will help lessen the roller/brush marks, but you will always have them, spraying applies smaller beads of paint, hence why it's a smoother finish. You will want either an airless sprayer or an HVLP gun, though I'm not certain that an HVLP will shoot something as thick as latex, it is used primarily for lacquers and stains.

If your samples are on surfaces that you intend to keep, you can sand them once cured and shoot them again to smooth them out.

I'm not really planning to do anything with these pieces. I'll just paint the other side of them with a sprayer. I ran across this post and the author makes this sprayer seem like it's heaven sent. I, on the other hand, am a bit skeptical. http://www.addicted2decorating.com/the- ... inish.html

If something sounds too good to be true, it probably is.

The problem with air guns is that they blow a lot of air, so you not only get a lot of drift and overspray, it dries the material out before it has a chance to hit the surface and settle. If you've got $100 burning a hole in your pocket, give it a shot, otherwise, save your money and put it towards something that is actually going to function as advertised.

I would shop for an airless sprayer, Wagner makes some inexpensive ones, you could probably find a decent professional grade one on Craigslist, or you could rent one, just make sure that it has been well cleaned before you start trying to use it and try to get a brand new tip or go buy your own tip so that you get the best possible results from the rental equipment.

I use an electric sprayer for trim and doors. Here is a discussion from another post. viewtopic.php?t=5444

Guess I'll be going with a spray gun then. Probably will have to wait until I get in the house to try it out. Don't think my apartment paint station will handle a spray gun.

You think that gun will give a real smooth finish for cabinets? Also, I might have asked this already, but what kind of paint should I be looking to use for kitchen cabinets? Latex, oil etc?

When I've asked the KM dealer this question I always get "alkyd", which is the oil replacement. Supposedly it has a harder finish that stands up to the abuse and moisture that cabinets have to endure. I've not used alkyds enough to have an opinion on them, most of what I have done is latex flat and semi-gloss work with only the occasional kitchen cabinet paint job.

This gun gives me a smooth finish on trim and doors with latex paint. I would be guessing that it would spray alkyd paints pretty good as well. If you are buying one then I think I would go to the same version as I have but the HVLP type. Should be better for cabinets and less overspray i believe.
