Stain All Sides with TWP?

Stain All Sides of the deck board with TWP? 

When staining a deck using TWP, is it necessary to stain all sides of each board? Consider the reason for staining wood – to shield it from weather damage, which causes rot and decay. This can lead to an unsightly appearance and structural failure.

Wood that is exposed to the elements will experience constant changes. Wood swells as it absorbs water and moisture, then shrinks when it dries out. These constant changes begin to break down the cellular structure of the wood causing it to crack, split, and warp. Ultraviolet rays fade and discolor the wood leading to a neglected appearance.
To prolong the life of any wood structure, and help maintain its original appearance, it needs to be coated with a weather-resistant stain like TWP. However, because at least one side of the boards will not be as exposed to weather as the other sides, it is not necessary to stain all sides with TWP. The bottom sides of deck boards, for example, are not exposed to much water or UV rays.

The only reason to stain all sides with TWP would be for aesthetic purposes. On a second-story deck, having all sides stained with TWP would be more appealing. This is a purely personal preference. To stain all sides with TWP for appearance is going to be more expensive and labor-intensive. It would take double the amount of stain and time to stain the underside of a deck.

To ensure the wood is shielded from weather and will stand the test of time, staining with TWP is a good investment. To stain all sides with TWP is really only for appearance where applicable but certainly is not necessary. It is really up to the deck owner whether or not to stain all sides. Not doing so will not lend a hand to weather damage or shorten the life of the structure in any way.

We used TWP last year on our cedar pergola and now want to restain the floor of the deck with TWP. The pine is 5 years old and is peeling in some areas. We can strip and brighten using your products and sand if necessary. How would we know if we need to purchase any of the additives to help with the stripping? I would hate to get the stripper and then wish we would have bought the additives also. In your experience does the TWP last longer on cedar or pine? My husband wants to rip out this deck and replace with cedar so the TWP will last longer and we don’t have to keep redoing the staining every couple of years. Is it necessary to strip the old TWP or can you clean the wood and apply a coat of stain when necessary? We will keep the pine deck if we don’t have to strip it every few years.
Thank you for your help.

Hello,

I have a pressure treated deck that I have stained every three years with 1502 for the past 12 years. It always does a great job. I have had to flip one board (curled on the ends). When I stained the deck two days ago this board did not darken up to match the others. I didn’t think to give it a wet-on-wet coat. Is there anything I can do now to darken it up a little?

My “covered” porch is treated pine, 10 years old, been stained once (6 years ago) and it extends around the entire circumference of my house. While it is covered, the outward edges received more rain and sun and thus take more abuse from the weather. I also have dogs that like to run on the deck. So I’m looking for the best protection I can get from rain, sun, and dogs. I know, that’s a lot to ask for. But the deck has weathered very well considering it’s mostly covered. I don’t really need a restore type product as I don’t have the damage. I like the idea of a solid color stain and need it in a “grayish” color. Our climate is 6B, on the Missouri / Arkansas border. Temps can get to 100 in the summer and single-digit in winter. Which stain would you suggest and can I get it in a gray color? Thx in advance.

In late 2013 our deck was re-stained with what I was told was TWP + Radcon. Apparently a blend of what now would be TWP 1500 and TWP 200 (for more pigment). Local companies mention a mix/blend of 1500 and 200 from 80%/20% to 20%/80%. The concerns being that the more TWP 200, the longer drying time and the higher chance of pigment rubbing off.
Comments??
P.S. I searched the TWPStain.com web site for Radcon and did not get any hits.
P.P.S. Location is Northern California, SF Bay Area about 3 miles from the coast. Fair amount of daily sun on the deck; hot occasionally; winter rains

Is “Radcon” a ‘thing” – that is, is it a specific product or a specification of the mixture?
Alternatively, is it generic and is term to describe a mixture, of any proportions, of TWP 200 & TWP 1500?

I am thinking to use your stain stripper and brightner combo then stain with TWP. I would like to lighten the wood as much as possible. Do you have any before and after pictures of log homes having used this product? How difficult is the stripper to use and how is it applied? Will it harm my patio which is attached to house.?

On waiting 48 hours: I’m currently in a very limited window of opportunity to get stain on a prepared deck. If I wait 48 hours, we’re expected to have rain the evening of the day I want to stain the deck. I have a moisture meter for wood and I’m not afraid to use it. The deck has been drying well since washing. Do you know the moisture percentage that I should be looking for before applying stain? I’m guessing somewhere in the 5 to 12% range?

For prep, prior to using TWP, we sanded the entire house to get the very old other (don’t know brand) stain off the logs.

I plan on using your TWP Cedartone 101 on my new 2×4 cedar deck boards. I would like to first use a preservative on all six (6) sides before I install the 2X4. I plan on using the following procedure before using your stain:

1. Remove the “Mill Graze” with your product Gemini or Wolman Deck and Fence Brightener.
2. Power wash the brightener off.
3. Use Woodlife Classic Clear Wood Preservative on all sides and three coats on the cut ends.
4. Install the boards to the joists.
5. Six (6) months later use a brightener then put use one coat of your TWP Cedartone 101.

Will this be okay?

We have used the Gemini prep on our cedar deck and getting ready to stain. We have deck skirting out of cedar that slightly touches the ground to keep rabbits out. Some of the skirting is on rock but some is going into mulch. My question is when staining towards the bottom – should I let the stain run at the very end to prevent my brush from picking up any mulch or debris? I have raked away debri but the ends are dirty.
Thanks for the help!

I live in MD and my deck is many years old and weathered in some spots. It was kiln dried pine and has been stained twice with oil-based Olympic semi-transparent (caramel color). Olympic has now switched to water-based stains which I would rather avoid. Because I live in MD, I guess I have to use TWP 1500 and I was thinking about 1516 – Rustic since it seems closest in color to how the deck looks in most spots. I have power washed the mold/mildew off but I have not removed all of the pigment from the previous stain. Is that required ? It has been many years since my last staining and I assume the wood will quickly soak up the new TWP stain. Please advise when you can and thanks.

Hi — I live in Knoxville, TN and my ‘new’ BACK deck is 18 months old and was done with kiln dried pine. It has never been stained. I recently pressure washed it. I bought Sherwin Williams Deck stain, read about your product and am returning SW now and buying yours :)). With that being said, I’d like to know which stain is best to buy for my area (100 or 1500) and my deck gets full sun exposure. It is approximately 550 sq.ft. based on your calculator (16×18 deck w/9 48″ steps. Would you recommend the 5 gallon bail or less? One or two coats? Do I still need to do add’l prep work? Would you recommend brushing on the verticals and using paint pad on decking or for a novice, can I get away with spraying the deck? Need to do the option that will turn out best for a person never having stained a deck before :)).

Lastly, I have rough cut cedar posts on my FRONT porch — used SW on them and the railings 5 years ago — looks horrible now, dark & graying. What can I do to make them look “fresh” again, anything? Then I will stain with the cedar stain that I plan on buying from you.

THANK YOU SO MUCH for your time and help!! Can’t wait to get this project going. Tried to upload photos, but couldn’t get it to work.

One thing I would say to anyone using this product is this. LET THE WOOD AGE A LONG TIME! I built a beautiful deck last Summer and let it age about 3 months before prepping and staining it. One year later I have mildew, stains, and lots of places where the stain has just worn through. The deck has very little use most of the year, so I know it’s not wear. I’m fairly certain it just needed more time to dry in the Pacific Northwest. So this Summer, I am stripping it all down and letting it dry another few months and then re staining. What a pain. It sure looked beautiful for a couple of months. Hopefully, this next application will retain its beauty. In the meantime, I’ve got to order more stain. Bummer.

I recently built a cedar fence with new rough cut cedar. I also have 4″x4″ treated posts and treated 2″x4″s. It has been completed for about two weeks and I won’t be able to get to staining it with the TWP 100 that I purchased for another two weeks. Basically a month of weathering. I live in WA state. Do I need to do anything to prep the wood before I stain it? I will wait for a period of four days of dry weather (48 hrs to dry and 48 hrs after I apply the stain to dry). I currently plan to:

1. Do zero preparation since it is new wood.
2. Spray with a pump sprayer and than back brush.
3. Apply a second coat within 30 minutes using the same method of application.

Any suggestions or corrections? Thanks!

I have a new deck (decking being put down right now) and while the pine is treated it has been kiln dried afterwards. Do I still need to wait a season to apply the 1500 for good penetration? Do i need to use any products like brightner or cleaner on it before applying? Everything states since it’s new wood I should only do one coat (which I’m okay with that!), I assume this is so that way you only apply what the wood can absord, but with it being kiln dried should I do 2 coats as if it has seasoned?
Thanks

I live in WI. I have an existing cedar deck that I buff sanded to remove years of old stain. In June, we built a cedar addition to the existing deck. The new addition has rough cedar skirt board. I’m planning these steps: 1) Order Gemini cleaner and 1500 natural color stain. 2) Use Gemini cleaner on existing deck now and stain after drying. 3) Stain new skirt board now. 3) Wait until October to stain new cedar addition after cleaning with Gemini cleaner so it’s protected before winter. What do you think? Finally, can I stain new cedar lattice now, or should I wait to age the wood? Will the Gemini cleaner damage aluminum railing? I plan to cover it.

You don’t you just do it all at once in the Fall. Much easier. It should not damage the spindles but not all spindles are made the same so always test first to see if there is a reaction. The spindles without a clear coating on them may have an issue.

Should I reapply Step 1 to get a smoother finish before staining? Do I need to use the neutralizer/brightener again? Can I spot spray the blotchy spots or would you recommend I spray the whole area?

There was a lot of residue during the cleaning process. I scrubbed it several times and rinsed numerous times both scrubbing and spraying.
The wood is a nice cedar color when wet, but is drying to a very light color. I just thought it was the brightening agent. I’ve followed the directions, so not sure what to think.

You might need to use a pressure washer after applying the cleaner as it seems form the picture you are not removing all of the oxidized wood cells while scrubbing.

I have a 14 year old mahogany deck on a covered porch that still has an old coating of Defy stain for hardwoods on it. The deck is being sanded and several mahogany boards are being replaced as they have rotted at the ends. Since I will have a mix of old and new wood, is it necessary to wait 4-12 months before staining the deck with the 1500 product?

Yes you can do that but make sure to saturate oil rags with water when done to avoid accidental spontaneous combustion.
