Topic tags/keywords: question finishing

I am building this wall of bookshelves for my sister. She is planning on having another kid and needs to clear out the 2nd bedroom which is currently her sewing room/ catch-all. They have a large finished basement and are having me build a Multipurpose bookcase for books, dvd storage, and murphys bed style sewing table. and just for a little fun, a hidden bookcase door to the office.

My question is, what is the best type of paint to use for this project? back in highschool i once painted a cheap tv unit with some latex paint. it seemed that anytime i left something heavy on it for longer then a day it would stick to the surface of the paint. not always to the point of peeling the paint off, but enough for me to be cautious about using it on a real project in the future.

any ideas or have you used something in the past that has worked for you? any help is greatly appreciated.

Here is a sketch-up of what it will look like.
bookcase closed

and one of it opened up.

Latex with a gloss or semigloss finish will remain sticky forever. Not to the touch, but like you noticed, things left sitting for long times will stick.

You might want to try a flat or eggshell latex, and topcoat it with a waterbased poly.

i’ve always used killz as a primer. the oil based one, not latex! after it has dried for about 24hours, i sand the mdf and all the edged come out glassy smooth. then i use whatever top coat i want. using a latex primer wil not give as good a finished product.

+1, Dan.
I’m in a pretty dry climate, but I’ve never had any problems with sticky latex enamel. I always use high gloss and coat with a water based poly.

Unless your compressor can kickout about 21 cfm, Becker Acroma will do you little good but thats what I use and the again, you need to strain/filter your paint, add catalyst, add thinner in the right percentages and then run it through a viscosity cup…...........all a pain in the @$$ and you have to do the same thing for the primer.

I like the acrylic paints and primers…....more money but less waste, very durable.

I just painted some MDF shelves, I use BIN Shellac Primer to seal the mdf, an it worked great. It dries super fast so you can throw two coats in 2 hours to seal up all the end grain. Make sure to pre sand the end grain to 220 or so first.

I used latex semi gloss, and I would not recommend it. It was a pain to spray, and I feel that it would stick if something heavy was left on it. Luckily, this only stores paper.

Here’s something to consider. A few years ago, I got the idea to paint the cabinets in the kitchen. I went to the local paint store and they recommended a Pittsburgh paint called “Direct to Metal” (DTM). They said the paint was really for applying to metal but does great on any surface. The thing that sold me on it was when they told me how durable it was. They said that the county’s high schools were using it on their school’s walls because it could hold up to the abuse. I had just finished putting up while (ice) tile on the walls above the cabinets and asked for the brightest white they had. The paint worked great.

Cool project. If you don’t care (or it’s not a problem), just use oil based (alkyd) primer and paint. Then it’ll be hard and you can sand it easily. The vapors don’t hang out that long in my opinion. If you use latex I would suggest minimum thin coats. Then let it cure for a period of time. I’ve heard up to a month on other forums, but you can be the judge. Most people don’t have the option to use a sprayer.

Tim,
Depending on color, and there are a lot, have you condidered milk paint? Seriously, it goes on, STAYS on, and can be topcoated with polyurethane, shellac, or your choice to smooth, deepen or protect the color. It’s not very expensive, and somewhat different to apply, but you can bet your bippie the next time my deaughter wants a painted piece of furniture, it’ll be milk paint ! Latex on furniture sucks. Get the most recent issue of Woodworking Magazine to get their perspective.
