What to Consider Before Buying the Redwood Sealer?

deck stain buying guide

Types of Redwood

Knowing about different types of redwood helps you determine the kind you own, and eventually, it will help you choose the best sealer for redwood.

Let me name the three types of redwood –

  • Giant redwood.
  • Coast redwood.
  • Dawn redwood.

Giant redwood is the most massive type among these three, having spiky leaves. They have conical trunks and soft bark.

Coast redwoods are tall; like the giant redwood, they can live up to 3000 years. Their trunks grow straight sidewise, and they have thick, fibrous bark.

Dawn redwoods have conical shapes varying in maximum height.

In most cases, the sealers don’t vary entirely on the type of redwood. But in some cases, you might see one sealer is better than the other for a particular kind of wood.

Work Piece

Some sealers are mainly made for exterior use, like KILZ L832211 that I mentioned above. Some sealers are made for both exterior and interior use. Some are not good for furniture; similarly, some sealers are made to protect the table better than anything else.

If you seal the outdoor fence or redwood deck, you need an expert to protect the surface from weather elements like rain and snow, giving UV protection and moisture. It must be equally helpful in preventing mildew growth from getting the best results.

So, considering the workpiece to choose the best sealer for a redwood is vital here.

Main Ingredient / Types of Redwood Finishes

You will find multiple types of redwood stains, like oil-based, water-based, epoxy types, etc.

All these types have their own set of expertise. Some are better for furniture, and others for exterior redwood objects like fences, decks, etc.

Before choosing one, you must ensure that a particular type contains the desired ingredients.

For example, the oil-based redwood deck’s stains typically give a glossy look, which you will want to apply on furniture without any second thought. Oil-based are pretty experts in protecting against mildew and mold growth.

On the other hand, some users prefer epoxy to oil-based outdoor fences as they tend to withstand harsh weather conditions better than their oil-based counterparts.

Water-based redwood deck stain is another new but widespread form of wood stain. Water-based redwood deck stains contain the lowest VOC; they are easiest to clean, dry fast, and cost down. However, they tend to give low gloss.

So, choose the type of sealer based on your expected outcome.


The wood deck stains can be divided into four levels of opacity.

  • Toner.
  • Semi-transparent.
  • Semi-opaque.
  • Opaque.

Toner is the most straightforward type of stain. They don’t change the outlook of the wood.

Semi-transparent is the most popular among users. Semi-transparent deck stains add color to the surface, but you can still see the wood grain as they are not thick.

Semi-Opaque is also known as semi-solid. It has much pigment to hide the wood grain, giving the wood a rich color.

Opaque is a solid stain among users and can provide maximum protection and ensure more longevity than others. It contains the highest amount of pigment.


When purchasing the best one, consider the amount you will buy.

All the companies offer different sizes of containers like 1 gallon, 5 gallons, etc.

First, you must know the area you need to cover to seal the surface, then decide on the required amount.

A standard sealer can typically cover 250-400 square feet for the first coat. For the second coat, you get more coverage per gallon.

Goof Proof

Goofproof mostly means ease of use.

Almost every redwood sealer is straightforward to apply using a brush, sprayer, or roller.

Make sure the one you buy is easy to apply with those simple tools. You will want an airless pump sprayer to get the best results.

Health Hazards

The Volatile Organic Compound (VOC) level is vital before buying a stain. Several states impose regulations on the VOC level, and it’s for a good reason.

High VOC is quite hazardous to health as it produces strong fumes. It will cause health issues in the long run for humans, the environment, pets, etc.

So, choose the stain that contains low VOC.


Although I’m writing this article to guide you about redwood sealers, remember that most sealers apply to various other wood types.

Some deck stains are equally applicable to old rotten wood and new wood. Some are only good for new wood.

Some sealers/deck stains are better than others for softwood; some are equally good for softwood and hardwood.

So, knowing the stain’s application will give you an extra benefit to using it for various wood types.

Benefits of Sealing Redwood

The core benefit of sealing redwood is protecting it from weather elements like snow, rain, UV, etc. Notably, sealing or staining the wood projects for external objects is vital.

You must also keep the redwood fence, deck, or siding from mildew and mold growth. Not to mention, moisture is another element you must keep the wood objects from.

All these can be achieved by sealing the redwood.

Although sealing and staining are called interchangeably, there is a fine line between these two.

Sealers work outside the surface, and the deck stains penetrate the wood to provide waterproofing benefits. Most of the modern-day solutions are two-in-one, though. Meaning they have both the sealant and staining formula inside.

Why is Sealing Redwood Better than Painting?

Sealing and painting both have their upsides and downsides.

While the painting is also easy, like staining, and you can choose from so many color options for painting, at the same time, it’s not the expert in protecting the redwood from so many elements like UV rays, mold, mildew growth, moisture, etc.

Staining and sealing make the wood surface waterproof better than painting; hence the durability of the redwood fence or deck increases.

Painting makes the surface slippery, but staining or sealing doesn’t make the surface slippery.

When it’s about keeping the natural look of the wood or increasing its beauty, wood stains and sealers are the solutions you need to apply.

Painting won’t keep the natural look at all.

On top of that, you control the opacity you want if you seal or stain, which is impossible when you paint. The painting will always have several thick layers over the surface, making it an opaque coating.

Staining or sealing is more budget-friendly than painting.

Best Time To Seal the Redwood Deck

Best Time To Seal the Redwood

Once you install the redwood deck, fence, or whatever is made of redwood, it’s time to seal it.

But wait.

You don’t have to seal the structure after finishing the installation. Wait for 6-7 months before you seal the redwood deck/fence.

It’s because, by this time, the wooden structure gets enough time to open up the pores, resulting in more sealant going into the surface with ease.

During the application process, ensure the temperature is within the manufacturer’s recommended range. Some deck stains are ready to apply immediately, regardless of the temperature. On the other hand, some deck stains work only within a specific temperature range.

Don’t apply the sealer or stain right after the rain. Give the surface enough time to dry up before sealing.

In most cases, you will want to seal the redwood deck under ample sunlight so the sealer can dry.

How to Apply Sealer on Redwood?

Applying sealer on redwood is probably one of the most straightforward jobs anyone can do, whether a professional or a DIYer.

Let me summarize the steps involved in sealing redwood –

  • First, cover up the plants and other furniture where you won’t apply the sealer.
  • Then, pressure washes the surface and gives it enough time to dry perfectly. It’s essential to clean the redwood before sealing.
  • If it’s an older redwood deck or fence, strip off the previous finishing through sanding or using any chemical stripper.
  • Put on the necessary protective gear.
  • Now, start applying the sealer. To get the best results, use an airless pump sprayer or brush.
  • Give it enough to dry and cure.

This is how simple it is to apply sealer on redwood. Please don’t go cheap in buying the sealer for redwood.
