Can You Paint Over Sealed Wood?

If you are going to paint over sealed wood, it’s best if you have some experience with sealing. If not, then get yourself acquainted with the basics before attempting to seal your home. Sealants will definitely make your job easier and save time when doing any kind of painting project.

Before getting into the details of how to apply sealant, let’s first look at why sealing is necessary in the first place.

Sealing Your Home For Painting

The main reason to seal your house is so moisture doesn’t enter the structure. Moisture can cause mold growth which could lead to damage or even collapse of the walls. If there was no airtightness, moisture would easily escape through cracks and crevices in the wall causing rot and decay.

When you seal up a room, you prevent moisture from entering that area, but it still might seep in from other areas.

There are several types of sealants available for homeowners to choose from. There are traditional sealants like vinyl caulk and drywall repair products, but there are also new products such as waterproof coatings. These waterproof coatings don’t require any additional work on your part, they just need to be applied to the surface where you want the coating applied.

They’re usually non-toxic and safe for most surfaces.

How To Apply Sealant?

There are several types of sealants available. There are also different kinds of applications for each type. Some sealants work better than others for certain purposes, such as sealing doors and windows.

Sealant products come in various strengths and types, ranging from those that don’t require much effort to those that need a little extra attention to avoid cracking.

The first thing you need to make sure of is your tools are working properly and clean. You don’t want any dirt or dust in the sealant blocking it from adhering properly. Make sure the temperature is about 75 degrees Fahrenheit or higher.

Then spread the sealant on one section of the wall at a time, not more than 10-12 square feet.

The most common type of sealant is caulk. This comes in tubes and is used to fill in cracks and holes. The process is very simple, most people have used some kind of caulking at one time or another.

Just squeeze some out onto a putty knife, spread it over the crack or hole, and smooth it out until its flush with the rest of the surface. That’s all there is to it. Spread the sealant using a plastic or fiberglass applicator. For added strength you can also use a notched trowel to create grooves in the sealant. You should apply at least 12 mils of sealant per square foot for proper adhesion. Finally, clean up your tools and gloves before the sealant dries so it doesn’t become a mess later.

You should always check with the manufacturer’s instructions on how to properly prepare and apply their product.

Sealing Your Home Before Painting

Painting is an easy and fun way to add beauty and style to your house. A fresh coat of paint can instantly make your home look brand new. There are so many different colors, patterns, and textures to choose from.

It’s almost like decorating all over again. They usually include instructions with the package and you can also find information on their websites.

When it comes to painting over poorly applied sealant, it’s best to just redo the whole process. Using paint additives or primers might help with adhesion, but there’s really no way to patch up an existing sealant. If done improperly, a new coat of sealant could peel off right along with the old one.

Painting, however, can be a messy business. When you open those cans of paint you never know exactly what kind of mess you’re in for. Sometimes the paint seeps out of the can slowly.

Other times it comes rushing out like a tidal wave. You have to move quickly to get your base coat down before it starts drying. Then there’s clean up; it would be such a pain to scrape hardened white paint off of your hands.

The first step in painting over a badly sealed window or door is to remove the caulk. Clean off as much of the old sealant as you can without damaging the surface itself. Then sand down any raised edges, bumps, or uneven spots with sandpaper until everything is nice and even.

Next spread a fresh layer of thinset or sealant (depending on what’s recommended for your project) onto the entire surface you’re working on.

Sometimes it’s just easier to leave it on your hands.

The first thing you notice is how cold it is outside. Not record-breaking cold, but certainly uncomfortable. You’re surprised that you were able to sleep through the night with as little clothing as you have.

You look around for something to cover yourself with but see nothing suitable. The trees and undergrowth are too thin to make a blanket out of. Wait for the sealant to dry and then you’re ready for paint.

Semi-Transparent Colors vs Solid Colors

“Semi-transparent” paints are paints that allow light to pass through them, but still have a solid color appearance. They tend to have a subtle effect; in other words, they’re not as dramatic as a solid color paint. It looks like you’ll just have to make due.

You stand up and find that you’re a bit wobbly. You haven’t eaten or drank anything in who knows how long. You walk over to the closest tree and lean against it as your head begins to throb.

You take a look at your surroundings in the dim light of dawn. The full moon is still high above you, but its light is slowly fading with the arrival of the sun. Semi-transparent paints usually come in a variety of shades, ranging from nearly white (but still allowing less light to pass through) to nearly black (but still allowing most light to pass through).

You’ve decided that for this room you’re going to use a semi-transparent paint in place of the solid color paint. Which shade should you choose?

Lighter shades will make your room feel bigger, but not by much since it’s not a very large room to begin with. The trees around you look different in the daylight. They somehow look less threatening and more welcoming.

The earth around you is stained a deep crimson color, and there are small animal bones scattered around. There’s a path not too far from you that leads deeper into the woods.

You pick up one of the bones and inspect it. It’s been stripped clean of any flesh or meat. Whatever type of animal this bone came from, it isn’t something people eat.

You stand up and follow the path into the woods. After walking a fair distance you come across a small dirt road. It’s overgrown with weeds and is incredibly difficult to make out unless you know it’s there.

After debating with yourself you choose to follow the road. Eventually you end up at a huge iron gate with a sign.

“No entry, by order of the King.”

It’s quite the sight. The fence is incredibly long and goes on both sides as far as the eye can see. You’ve never seen so much metal in your life.

It must cover several miles worth of area. There’s no way to get through it. You decide to go back the way you came. You walk along the boundary of the fence in search of a gap.
