I haven't tried this out myself myself but I've read about using flat latex tinted to the color you want then top coating with poly. From what I understand, flat paint cures a lot faster that those with a shine and the you can topcoat with poly to get the protection you need and the sheen you want without being sticky. I'd just be guessing, but in that video i think it looks like semigloss to me. Google "poly over latex" and you find a bunch of advice. I've never painted MDF so I don't know how it reacts, but I hope this helps.
Also, as Bill Boehme said, alot of paints fall under the catagory of "latex". I would ignore advice from those that think latex paint contains latex.
That sounds like it might work, but if i can get the same effect with just paint, id rather just use paint since my budget is small and it would be easier anyways.
After a bit of research just now, im kinda leaning towards semi-gloss oil pant now instead of eggshell. Reason being, i want almost like a hard shell kind of feel and look that you get with gloss paint and gloss stains/clearcoats, but i dont want the super shiny look and reflection... i want a slight shine. I guess i dont really know right now since i havent even seen the finishes in person, only google images, so next time or when i go buy the wood and paint, etc. ill make sure to take a good look at the paint finishes and feel them, but i think semi-gloss is what ill go with. If im not satisfied with what finish ill get based on sample splotches display, or for whatever reason, ill ask questions.
Looking at pictures online like these: LINK
i really wish i could have a wood grain look on my future desk surfaces, even a wood floor look that doesn't have a continuous grain like in those pictures. Ive been thinking, maybe i can buy a few square feet or however much i need of wood flooring laminate or something, shouldnt be too expensive since its only like less than a dollar per square foot? And somehow i can mount it to the tops and sides of the mdf?
What do you guys think about this idea and everything else i covered here? Please help guys, thanks!
