Do I Need A Clearcoat Over Paint



I just finished building a toddler bed for my little girl out of MDF. I've already applied a coat of tinted primer, and I'm planning on two coats of latex paint and then applying some wall applique stickers. Is a coat or two of clear coat (poly or salad bowel finish) necessary? I thought it might help protect the paint, but it might be overkill.
Thanks.

You could put a couple coats of water based poly over the paint, but, yes, that would be overkill.

Is your latex paint a flat or an enamel?
Enamels are formulated for wear and don't need an additional coat of protection although a coat or two of waterbased poly may help to protect the stickers.

Thanks for the input.
From what i hear you saying, if I choose a clear coat, it should be water based, not oil based poly.
The paint sheen is satin.
Also, do you usually sand between coats of paint?
Thanks.

It is always a good idea to sand between coats - it both helps with adhesion and promotes a smoother finish; eliminates or reduces brush/roller marks and removes any grit in/on the coating.
Since you've been using latex, it makes sense to stick with a water base. Oil base poly does dry to a harder film = wears longer but it will alter/yellow the color underneath it. It will also amber as it ages. Waterbased poly dries clear and shouldn't yellow/amber any as it ages.
Satin enamel doesn't usually need any further protection but if you decide to poly - don't sand the enamel as the poly may not hide the sanding scratches.
