Sealing

This is the first task you need to do. Sealing balsa wood is not that complex of a process. But that is only if you follow the instructions carefully.

There’s a few steps given below that you have to follow!

Make sure you are following all of them accordingly.

Step 1: Arrange A Workbench

First, you need to arrange a drop cloth or a workbench to work over. Because, the process of sanding balsa and sealing it will create a mess. 

So, working on them will ensure that they are easy to clean. Also, you will be able to pick up leftover sealer and sawdust much easier.

Step 2: Sand The Balsa

Now, you have to sand your balsa using a 220-grit sandpaper. Apply a smooth motion back and forth so the wood surface is roughened up. 

As you can see, it is quite similar to sanding plywood.

Make sure to sand every part you’ll be staining. This way your primer and stain would stick better. 

Put light pressure so no holes or uneven smudges are caused on the wood. Might be a bizarre finish.

And then you have to start cleaning unfinished wood.

Step 3: Apply The Filler

Now you need to brush on a layer of wood filler. This is to seal the balsa wood surface. Plunge a regular paintbrush inside the wood filler bottle. 

After that, swab a thick layer of filler over the whole balsa surface. Do this until no wood grain is visible underneath. 

Make sure you do not miss any areas otherwise the paint would be uneven.

Step 4: Let It Dry

Leave the wood filler to dry for approximately 2 to 8 hours. Keep the balsa wood in a spot where it will not be touched. Wait until it is dry before moving on.

The dry time of wood filler may vary. It is approximately 2 hours. Thicker kinds may take up to eight hours. 

Step 5: Sand It Again

Now, you have to sand the balsa again using the 220-grit sandpaper. Use the same sandpaper you used for sanding the first time. 

Proceed with sanding till you notice the wood grain through wood filler. Doing this actually gives you a good and smooth surface for the stain to stick to.

Priming

The next thing in how to stain balsa is priming the wood. It will prepare the wood surface for a better finish. Plus, the stain will sit very nicely and evenly.

Here are the steps.

Step 1: Choose A Well Ventilated Area

Firstly, keep in mind that you need to work outside or a place that’s well-ventilated. 

Both primer and spray paint are the best for balsa wood. However, it produces a lot of fumes. 

That’s why make sure you work outdoors.

Step 2: Spray A Layer of Primer

Now, just spray a layer of primer on the balsa. It has to be a sandable primer. Before applying, shake the can well. Then hold it about 6 to12 inches from the wood. 

Spray using sweeping motion till the entire surface is covered. Keep the primer going. This way it will not pool or drip.

Step 3: Sand Using 400 Grit Sandpaper

You have to wait until the primer is dry and then sand it using 400-grit sandpaper. After that, again use the fine-grit sandpaper to give the balsa a light sanding.

Step 4: Complete The Coating

After you are done with all that, apply two more layers of primer. First, spray a coat of primer using the same process and dry it. 

After it dries, sand it again for a final coat. It will provide you an even finish when staining.

Staining

Now, the final task before we are done with the entire process. This is the most important part as well.

Up until now you have prepared the surface for this step. Now make sure you are following the steps properly.

Here are all the steps for staining balsa.

Step 1: Tape off The Balsa

Firstly, Tape off the sections which would be a different color. It will give nice and even lines for the stain. 

Use the painter’s tape for that. With that, cover all the areas which you want to be a different color. Or there would be the hassle of removing the latex stain from wood.

Make sure you do not use tapes which are sticky. For example, packing or duct tape. This can leave behind residue over the wood and damage the finish.

Step 2: Spray A Thin Coat

In this step you need to spray a thin coat of enamel on the wood. Or you can try applying latex paint as well. Then let it dry. These are known as the most preferable types of stains for balsa.

To apply, shake the can very well. Then hold the can about 12 inches away from the wood. This will make the finish even. 

Spray in a sweeping motion to cover the balsa. Just apply a thin coat first so the paint won’t run.

Step 3: Apply More Coating

Now you have to keep spraying the stain after the earlier coat dries. Continue till you get an even finish. 

Allow the first coat to dry out fully. Once it has dried, spray another light coat. Again, leave it to dry. 

Continue doing this till you get an even and nice finish. And it does not show the wood grains underneath the balsa.

You may need to apply even 3 to 4 coats to attain an even finish.

Step 4: Complete The Process

Now, you need to stain the remaining sections, if any, that were enclosed with a tape. 

In case you taped off any of the sections of balda, peel it off. Do it only when the first stain is fully dry. 

Then cover that dry section using tape and spray the remaining parts to stain.

And, in case you have only used one color stain, there is no need to tape. You do not have to paint anymore either.

Now, let the stain cure completely for 2 to 3 days. The stain should take somewhere between 36 to 72 hours to fully cure.

Leave the balsa alone during the time. It’s because the stain can be treated properly. After that, you may move it to the place you want it.

And that is it! You are successfully done with staining your balsa!
