If you aren’t willing to change your wood siding color, then using a sealer is the right deal for you, and the outdoor wood sealer will be the perfect choice for sealing.

Sealer is basically a transparent material used on the wood siding and helps enhance the wood siding’s natural color. Also, UV integrated sealers can protect the exterior from sunlight.

Now, move to the procedure of how to use the sealer.

• Prepare the yard

Before starting your work on siding, you must prepare your house’s yard so that other furniture doesn’t get harmed from stain splatters, scattered chemicals, or flying offal.

For more safety, it’s better to cover the outdoor furniture, appliances, plants with clothes, or anything you feel safe.

You might want to cut the branches that can be an obstacle in your work or touch your house.

• Prepare the siding

The wood siding should be prepared entirely before using the sealer and removed old paint layers and sealers as well.
Steps to prepare the siding –

 Firstly, sweep off the dust and meshwork from the surface.
 Look for inspections of any rot or superficial cracks.
 Replace the damaged pieces if there are found any.
 To remove old paint or stain, you can use a professional grade eliminating product.
 When the rest of the works are done, use a pressure washer or hose pipe to clean the wood siding surface finally.

• Apply the sealer

This is the last and final step of this process. When you have finished all the earlier stages, now let it dry for hours. Take the next step slowly to use the sealer and ensure the sealer that lands into every corner of the wood siding.

Note: If the brand you are using requires two coats, you must wait for the first coat to dry fully.

2. Staining

As it doesn’t need any primer, it is a bit easier and simpler. But you have to go through a process of steps. You have to choose a stain among all the capacity levels and also how much wood grain you want to show.

Before deciding, test several types of stains to choose the best for you, especially the exterior stains – because a see-through option will not protect against sunlight, as well as the thicker ones. So, testing is required to decide the optimum level.

Let’s get to the steps.

• Cleaning

Use a pressure washer to clean the surfaces of the siding thoroughly. Now use a bleach coating all over the surface, following the instructions. Let it dry and again use the pressure washer to wash off the bleach mixture. Now prepare the siding for staining.

• Wash the surface

Keep patience. Let the wood dry out completely. To prolong the wood siding’s life, it’s essential to remove all the water from the wood and stop it from causing patches to develop during the application.

• Use Caulk

To make the wood siding thoroughly watertight, fill in the gaps with a good quality exterior caulk. You need to use it on every bit of gap that can possibly let moisture in behind the material.

• Apply the stain

Now pick an oil-based exterior stain that matches your desired colors’ pigment. Don’t forget to spot-test it first before using it.

Now use a very wet brush to apply the stain. This will ensure that the stain penetrates the wood siding properly and get a good seal for effective protection.

Do not use the stain over any surface in direct sunlight. This will ruin the sleek finish.

After you have finished the staining, you have a well-colored siding that is also equipped to stand up to the elements.

3. Painting

If you want to cover up any imperfection of your wood siding and want to give your home a colorful look, painting the wood siding lures another successful way. You can enjoy a nice textured surface without all the wood grain variations you will get with staining

• Doing Pressure Wash

Before you think of applying a coat of paint, make sure the surface is adequately cleaned. To serve this purpose, use a pressure washer to all the boards on the house. This will clean up the body and help the paint to stick to the surface.

• Use Caulk

Make sure that you use a professional grade exterior caulk, which is invented from polyurethane or silicone, to prevent all the leaks so that it doesn’t leak water. Fill in all the gaps appropriately so that the paint can also protect this surface and make the application better overall.

• Prime the Wood Siding

Choose a primer that matches the actual paint color and is tinted a few shades lighter also. This will make the paint even and allow the color to stretch further.

To ensure you have the best result, make sure to coat every inch of the sidings properly.

• Use the paint

After you have applied the primer properly, it’s time to apply the paint now. Try using a sprayer, as it is faster and more likely to achieve an even coating.
But if you are not experienced enough, you can go with a brush or a roller. If you are going with the sprayer, cover all the neighboring objects and your backyards also.

Apply the first coating and let it dry. After the first coating dries appropriately, apply a second coating to make it long-lasting.
There you go, three steps to deal with sealing wood siding.


Whether you choose painting, staining, or sealing for your home’s wood siding, it’s essential to apply an adequate finish in every seep of the surface. It will enhance the wood siding’s lifespan and bring out a new shiny texture on the exterior of your house.
