What to Consider Before Buying the Redwood Sealer?
Types of Redwood
Knowing about different types of redwood helps you determine the kind you are owning, and eventually, it will help you choose the very 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, and like the giant redwood, they can live up to 3000 years. Their trunks grow straight sidewise, and they have thick bark that is kind of fibrous.
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.
Some sealers are particularly made for exterior use, like KILZ L832211 that I reviewed 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 furniture better than anything else.
If you are going to seal the outdoor fence or redwood deck, you need something that is expert in protecting the surface from weather elements like rain, snow, and gives UV protection, moisture. It needs to be equally useful in preventing mildew growth for 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 some are better for exterior redwood objects like fences, redwood decks, etc.
Before choosing one, you have to make sure that a particular type contains the ingredients to give the desired outcome.
For example, typically, the oil-based redwood deck’s stains give a glossy look, which you will want to apply on furniture without any second thought. Oil-based are quite expert in protecting 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 popular form for wood stain these days. Water-based redwood decks stains contain the lowest VOC; they are easiest to clean, dries fast, costs low. However, they tend to give low gloss.
So, choose the type of sealer based on the outcome you are expecting.
The wood deck stains can be divided into four levels of opacity.
Toner is the clearest 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, and it gives the wood a rich color.
Opaque is known as a solid stain among the users and can provide maximum protection and ensure more longevity than the other ones. It contains the highest amount of pigment.
When purchasing the best one, consider the amount you are going to buy.
All the companies offer different sizes of containers like 1 gallon, 5 gallons, etc.
First, you have to know the area you need to cover to seal the surface, then decide on the amount you require.
Typically, a standard sealer can cover 250-400 square feet for the first coat. For the second coat, you get more coverage per gallon.
Goof proof mostly means ease of use.
Almost every redwood sealer is straightforward to apply using a brush, sprayer, or roller.
Make sure the one you are buying is easy to apply with those simple tools. To get the best results, you will want to use an airless pump sprayer.
The level of Volatile Organic Compound (VOC) is vital to consider before buying a stain. Several states impose regulation 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 the redwood sealers, keep in mind that most of the sealers are applicable to various other wood types.
Some deck stains are equally applicable for both 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 use it for various wood types.
Benefits of Sealing Redwood
The core benefit of sealing redwood is to protect it from different weather elements like snow, rain, UV, etc. Notably, for the exterior objects, it’s vital to seal or stain the wood projects.
You got to keep the redwood fence, redwood deck, or redwood siding from mildew and mold growth as well. 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 from outside of the surface, and the deck stains penetrate into 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 redwood 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 the 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 not possible when you paint. The painting will always put several thick layers over the surface and make it an opaque coating.
Staining or sealing is more budget-friendly than painting.
Best Time To Seal the Redwood Deck
Once you install the redwood deck, fence, or whatever is made of redwood, it’s time to seal it.
You don’t have to seal the structure right after finishing the installation processes. Wait for at least 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 applying process, make sure the temperature is within the manufacturer’s recommended range. Some deck stains are ready to apply right off the bat, 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 that the sealer gets the opportunity to dry.
How to Apply Sealer on Redwood?
Applying sealer on redwood is probably one of the most straightforward jobs that anyone can do, whether he is a professional or 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, then 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, better 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. It would be great if you don’t go cheap in buying the sealer for redwood.
