3. Mask baseboards and trim

Use painter’s tape to mask off the baseboards, window and door trims, and molding to avoid getting any primer or paint on these surfaces.

Deglossers

Another option to sanding is a liquid deglosser, which can quickly, easily and safely remove glossy paint if you’re short on sanding and cleanup time. Most deglossers are environmentally friendly, non-toxic, non-combustible, biodegradable, and extremely concentrated, so removal time and product use is at a minimum.

Deglossers can be found through any home improvement outlet, hardware store or online retailer. One product that is good for removing glossy paint, Krud Kutter’s Prepaint Surface Preparation, can be found through Amazon. Be sure to follow directions exactly in order to accomplish gloss removal.

Can You Paint Lacquer Over Enamel Paint?

This one is really tricky. Lacquer and enamel paints have kind of a love and hate relationship. So while it is possible to cover Enamel Paints with Lacquer Paints the outcome can be quite unpredictable.

It is possible to paint Laquer over Enamel Paint. Lacquer, however, has a tendency to lift Enamel Paint off of the painted surface. Apply a little bit of Lacquer in a location that is hard to see to test how the painted surface reacts to the Lacquer.

It is generally possible to paint Lacquer straight on Enamel Paint if the paint was not sealed with a topcoat. But it is kind of hard to predict if the outcome will be good because Lacquer can in some cases react with the Enamel paint and pull the paint of off the surface resulting in bubbles.

So it is recommended to test if the paint will be accepted well by the Enamel paint, by adding a small amount of paint in an area, that is hard to see.

In case the Enamel Paint is not reacting well to the Lacquer you can still remove the previous paint job from the surface by sanding the entire object. Or, if you are lucky and the enamel paint was not applied with a primer, then you can sometimes scratch the paint off of the object with a metal spatular.

Painting Over Oil Based Paint: Oil Over Oil

Here’s the kicker, I don’t recommend doing anything different if you plan on using oil based paint to paint over your old oil based finish.

Even if you paint over your old cabinets (or whatever you are painting), and they have a glossy surface that you don’t properly prep or prime, your new oil based finish won’t bond properly and you’ll likely have peeling and chipping issues in the future.

Can You Paint Over Wallpaper?

If you ask a painting expert or paint manufacturer, you will likely be told that the best approach is to remove the wallpaper first and remove any residual adhesive before painting. But there are times when removing the wallpaper can actually harm the wall beneath.

That can happen if the wallpaper was installed over unfinished drywall or plaster. Or you might be facing the removal of multiple layers of wallpaper, which would make the task exponentially more difficult.

Steps for Painting Over Wallpaper

Follow these steps to learn how to paint over wallpaper in your home.

Step 1: Clean the walls

Wipe the dust and dirt off the walls with a barely damp cloth. Primer won’t stick well to a layer of dust.

If the walls are greasy and grimy (think highly-used kitchen), clean them with a diluted solution of TSP. Don’t soak the walls with the water or solution because that could soften the adhesive below the wallpaper and cause it to loosen or bubble.

Leave plenty of time for the walls to dry.

Step 2: Repair any damages to the wallpaper

Look for peeling edges or seams, as these are the weakest areas in terms of adhesion. Some experts recommend using a thin layer of wallpaper seam adhesive to reattach these loose fragments.

Another recommendation is to lift those areas with a thin putty knife, cutting the loose bits away and filling in with spackle to create a level surface, then sanding lightly when completely dry.

If the wallpaper has a texture you don’t want to detect through the paint, the whole wall should be sanded until smooth, using either a palm or orbital sander. With a slightly damp cloth, wipe away dust.

Step 3: Tape off molding and trim

Using painters tape, carefully tape off any molding, trim, wainscot, or baseboard you want to protect.

Step 4: Prime the walls

No matter which type of topcoat you will be using—oil-based or water-based—you want to use an oil-based primer. That’s because a water-based primer could soak into the wallpaper and loosen the adhesive.

An oil-based primer will not do that. Just as with painting, use a brush to cut in the corners and edges, then use a roller to finish the big stretches.

Allow plenty of time to dry according to the manufacturer’s directions. Make sure there is plenty of ventilation in the space.

Step 5: Start painting

Once the wallpaper is cleaned, repaired, and primed, paint it as you would any other surface. This will be especially necessary if the wallpaper has a bold pattern, or if you are applying light-colored paint over dark-colored wallpaper. You’ll likely need two coats, with plenty of drying time in between.

Painting over wallpaper can be done, and sometimes it should be done rather than removing the wallpaper.

As with many home improvements, the quality of the result depends on the effort exerted at the beginning. In other words, it’s all in the preparation.

1. Clean the walls

‘The first step in painting over wallpaper is to make sure the walls are completely clean,’ says Emily Perez, Head of Design at Kitchen Infinity. ‘It is necessary to ensure that there are no particles of dust or other dirty things. The priming process is hampered if the wall is not properly cleaned.’

To get the walls clean, use a cloth to remove any dust or grime. It should be barely damp as you don’t want to wet the walls.

If the walls are greasy, you could use a mild detergent solution but you may need to use a TSP solution instead. Follow the manufacturer’s instructions and make sure you wear safety gear. 

Allow walls to dry thoroughly.

Why You Need To Prime When Painting Over Oil Based Paint

This is the real kicker when I get asked if it is possible to paint latex over oil based paint. No matter what, I always recommend using the proper primer for the project.

Primers are built for two main reasons (there are more, but these are the main ones) when it comes to painting the interior of your house.

First, is sealing and stain blocking. A primer is built to seal in and block stains such as water, grease, smoke, pee, and other stains. A good primer stops these stains from seeping through into your top coat.

The second main reason to use a primer is bonding. Primers are made to bond to the surface you apply them on and to bond to the new top coat you apply over them.

If you look around online, you can find very specific primers that are made for a specific application. Some specialize in bonding and are typically called “Bonding Primers” while others specialize in stain blocking.

A great general purpose primer that is great at both while having a low VOC content is Zinsser Smart Prime. This is my personal choice for all kitchen cabinet, window, door, and trim painting. Zinsser Data Sheet.

Zinsser Peel Stop is a exterior specific primer that is so good at bonding that it is sold to specifically stop exterior peeling!

Peeling Paint Warning

Always be cautious when scraping and sanding paint on older houses built before 1978, as there is an increased likelihood of any painted surfaces containing lead. It is good practice to wear a Respirator Mask when there is a risk of dust particles entering the lungs. These can be easily purchased at any local building merchant.
