How Do You Seal Ikea Greenhouse Cabinets?

When you buy a greenhouse, it’s important to know how to preserve it. This article will tell you everything that you need to know about sealing your Ikea greenhouse cabinets.

Sealing IKEA greenhouse cabinets is essential for maintaining optimal conditions for plant growth.
Silicone caulk or weatherstripping can be used to seal gaps and prevent air leakage.
Applying adhesive-backed foam tape to the edges of the cabinet can help create a tight seal.
Regularly inspecting and resealing the cabinets can ensure long-term effectiveness.
Proper sealing helps regulate temperature, humidity, and prevents pests from entering the greenhouse cabinets.

Paint With Benjamin Moore

For the interior of the cabinets, you want to use a high-quality paint that is specifically designed for plastic. This will help your cabinet last longer and prevent any damage or discoloration over time. 

You can use any type of exterior paint on the outside of your greenhouse cabinets, but oil based primers are recommended since they dry faster than latex paints do.

Stain With Varathane

Use a rag or brush to apply the stain, following the directions on your can. Once you’ve applied one coat, let it dry for at least four hours before applying a second coat. After it dries overnight, use your new cabinet as normal!

Use A Vinyl Laminate Coating

You’ll want to use a vinyl laminate coating for the best results.

You can apply it using many different methods:

Sprayer – You can purchase a sprayer and get the job done quickly. It will give you an even coat of paint, but this method can be messier than some of the others.

Roller – The roller is another great way to give your cabinet doors and drawers an even coat of paint or sealant, plus it makes it easier to apply too much product in areas that need less coverage than others.

Brush – Brushes are also great for applying coatings evenly because they allow you to spread out the product without putting too much on one area at once, which ensures everything gets covered completely without being too thick or thin on any particular surface (like a brush stroke).

Rag – Rags are another good option if you don’t have access to any other tools like rollers or brushes because they allow for more control over how much product gets applied per spot so that nothing gets missed while still making sure everything looks uniform after application has been completed overall throughout all surfaces being worked with at once (not just one area alone).

Cleaning The Lower Cabinets

To clean the lower cabinets, use a mild detergent and a soft cloth to wipe down the outside of each cabinet.

Use another soft cloth or sponge to clean the inside of each cabinet and wipe off any dust from the shelves. Finally, use another soft cloth or sponge to clean all sides of the glass doors and shelves.

Now that all your cabinets are nice and clean (and sealed), it’s time for you to seal them!

Sanding The Cabinets

The next step is to sand the cabinets. Use a sander fitted with a sanding pad and vacuum to remove the dust. 

Sandpaper suited to the job will allow you to get into corners and crevices and create an even surface for your stain or paint. If you’re using stain, use a paintbrush instead of spraying it on because spraying can create uneven coverage that may need touching up later.

To ensure the longevity and stability of your canopy, it’s important to reinforce the canopy top properly. Our article on easy tips for reinforcing a canopy top offers practical advice and techniques to strengthen your canopy, providing peace of mind during outdoor events.

Cutting A Hole In The Back Of The Lower Cabinet

To cut a hole in the back of your lower cabinet, use a jigsaw or circular saw. Wear safety goggles when cutting to protect your eyes from stray wood chips and dust.

  • Measure and mark where you want to cut using a tape measure, pencil, and ruler.
  • Cut along these marks with your saw blade set at 45 degrees (this will make it easier for you to access the fan later).

Painting Them With Loft Paint

If you can’t find a sealant that meets your needs, you may want to paint the cabinet doors and/or drawers with a paint that’s made for both indoor and outdoor cabinets. 

To make sure your new coat of paint will last as long as possible, consider using Loft brand paints by Valspar. These paints are designed specifically for use on household furniture like cabinets and drawers, so they’re guaranteed to stand up well against moisture damage. 

They also come in a wide range of colors including white! If you decide to go with this option instead of sealing up cracks yourself or purchasing pre-sealed cabinets from Ikea (which will be more expensive), make sure your cabinetry is clean and free from dust before painting it with Loft Paints.

Installing A Baseboard

In order to install the baseboard, you’ll need to first measure it and cut it to size. Cut your baseboard with a jigsaw or circular saw, but be sure that you’re using a blade specifically designed for softwood (i.e., wood that’s not hardwood).

Next, glue the baseboards onto the cabinet. You can use any type of wood glue you like here; we recommend using Titebond III Premium Wood Glue because it works well on both softwood and hardwoods and is waterproof once cured. 

We used clamps while our glue dried overnight so that it would adhere well—you don’t have to do this if you don’t have them handy!

Filling In Gaps

A variety of tools can be used to fill in any gaps between the cabinets and doors. Caulk is a simple solution, but it’s messy and can take a long time to dry. 

A putty knife is also an easy solution when combined with some caulk or another type of filler. Foam brushes are great for creating even surfaces when using caulk or other types of fillers, while rollers are good if you’re working on a larger surface area.

Painting The Top Shelf And Stemware Racks1

Use a paintbrush to apply the green paint to the top shelf.

Use a long-handled brush to reach the top of your cabinet if you’re using an extension ladder. You could also use a flexible extension pole, but make sure it’s securely attached as you don’t want it falling on you while you’re trying to get paint on there (unless you like pain).

If you’re using a foam roller, use it to apply green paint onto each rack in between glasses or other items that will be stored inside of them, then allow each rack time to dry completely before moving onto another one.

Sealing Ikea Greenhouse Cabinets Is Important

Sealing Ikea Greenhouse Cabinets is important because it protects the wood from moisture. If you don’t seal the wood, it will absorb moisture and eventually rot. 

Also, since you’re building a greenhouse and not a regular house, it’s likely that you will be using your greenhouse in wet conditions (rain).

You should use paint that is specifically designed for cabinets and other wood surfaces that need protection from UV rays (the sun), moisture, etc. Most paints aren’t UV resistant on their own—they need to be combined with other materials to achieve this effect.

Unlocking a canopy can sometimes be tricky, especially if you’re unfamiliar with the mechanisms. Discover expert tips and techniques in our guide on unlocking a canopy to make the process effortless and avoid potential frustrations during setup and takedown.


As you can see, there are many ways to seal Ikea Greenhouse Cabinets. The most important thing is to protect your cabinets from water damage and mold. 

If you don’t want to spend money on professional paint or vinyl laminate coating, then we recommend using a latex based paint for an easy DIY job. 

Just remember that none of these methods will last forever; make sure that you keep up with maintenance so that your cabinets stay looking great!
