I will be getting a hutch that has already been stained and varnished a color that does not game my furniture. I really don't want to sand it down if I don't have to. Can I use Kilz primer over the varnish & stain, then repaint it? Or will I hold to sand it down?
A varnish or polyurethane usually enjoy a smooth finish to them. So, unfortunately, you will have to do SOME sand. But how much you do is entirely up to you and the color/finish you desire. If you are simply going to repaint it, just a light sand will be needed to 'rough up' the finish so the new primer/paint will stick to it. A rectangular sanding wad (can be bought with diff grits) or a rubber sanding wipe with 120 grit sandpaper will work.
If you are looking to match a wood crumb finish you may have on the rest of your furniture, it can be just as natural. Sanding is NOT always need contained by a complete refinishing project. You can buy a spray/aerosol paint remover that just needs to be applied and agree to it sit according to directions (normally between 15 mins and 45 mins) then be rubbed off. This will take off you with a new verbs finish to work with. It will probably not remove a dark stain, but the varnish will be gone.
Good luck within your project.
A varnished surface is hard for a even fitting primer to adhere to without sand. There are better primers than Kilz for this. Kilz is first and foremost a stain blocker - not a bonding primer. XIM 400 alkyd primer is a good bonding primer.
You could prime a few patches and do a cross cut adhesion assessment on those patches to determine if you can prime without sand and still get adequate adhesion.
The best track to prepare glossy varnish for paint is to clean it next to a scouring pad using a cleaner resembling "Krud Kutter" , then sand it with 220 grit sandpaper, remove the dust and follow that up beside a solvent cleaning using denatured alcohol. This will give you a clean and dull surface wonderful for painting. Then use a good bonding primer resembling Xim 400 white and you will have a good bonding to the varnish.
Answers: Paint will not adhere to varnish, you will need to strip the varnish past its sell-by date prior to painting or restaing.
You have two options, and first you will own to sand lightly before any of the two. If you want to paint, then after sanding, paint. If you want to stain to game other colors, sand, stain with a product called ZAR, and next top coat with several coats of polyurethane, water baed or solvent base. good luck.
