Fall is approaching, which means it’s time to tackle some home improvement work. Why not start with the deck in your backyard? How does it appear? Is it beyond its prime?

Perhaps it’s time to change the color of your deck. You must apply a primer before painting it. A primer will help the paint cling to the wood better.

Check the sort of wood you have for your deck before you begin. If you’ve had your hypertension addressed, you should proceed with care. Here are some pointers on anything from what a primer is to which primer is best for pressure-treated wood.



What exactly is Primer?

Everyone who is doing this for the first time will need to understand what a primer is. What exactly is a primer? A primer is a paint-like liquid that is used to prepare and protect unpainted surfaces including wood, metal, and canvas against rust and water damage.

It’s essentially a protective layer for the wood against the outdoors. It also makes receiving paint more easier. The paint will stay considerably longer and will have a far nicer appearance.

A deck is an important element of your house that requires regular care to keep it looking beautiful and working properly. If the decking boards get too damaged, they may need to be replaced, which may be pricey.

A conventional oil-based primer and a modern latex-based primer are the two major forms of primer. A primer may help you save money by extending the life of your paint and helping it apply better than it would on bare wood. 

Primer may be purchased in the same locations where paint is sold, as well as online. You’ll also need to know what sort of primer you’ll need based on the kind of wood on your deck.

How to Put Primer on

We’ll teach you how to apply the primer to wood now that we’ve showed you different primers to buy. Primer is a chemical that dissolves while masking blemishes and imperfections on your wood’s surface.

When you’re completed, the little holes, knots, and stains won’t be visible, but there are a few things to check before applying the primer to the wood.

The first step is to ensure that your decking planks are clean. You may clean the wood with soap and water, but a pressure washer is the most convenient option. Check to check whether the wood is dry after cleaning it. You’re ready to go to work if the water droplets soak into the wood.

After that, double-check that the primer is correctly mixed. It should be poured into a bigger bucket and well mixed using a mixing stick. Take a brush and paint it on a surface to make sure it’s uniform. (You might use a piece of cardboard or something similar.)

If there are any heavy lumps in your primer, whisk it again. Then you must test the combination one again. You’re ready to apply the primer after it has a uniform texture.

Applying the primer to your deck is as simple as rolling it on the top surface and then brushing it down the margins between the boards. To get it into every nook of your decking planks, you may need more than one application.

Allow for six to eight hours of drying time after you’ve completed. If you have pets, you should probably let them out the front door. You don’t want your hard effort to go to waste.

Finally, when the primer has dried, you may begin painting your deck. If you’re unsure whether staining or painting the wood is preferable, we have further information on both! Read our other post if you’re still planning on painting your pressure-treated wood.
