Stain All Sides with TWP?

by TWP Help
 

Stain All Sides of the deck board with TWP?  – TWPStainHelp.com

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 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.

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… Read more »

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… Read more »

I have a 40 year old log home that was previously stained with CWF cedar color. It has darkened over the years and the wood looks dry. 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.?

We are building a cabin and have used TWP Cedartone on new white pine siding. We are seeing mildew and mold on the wood and thought TWP prevented such. We have take a piece of scrape stained siding to the supplier who agrees that it is mold and mildew. We don’t understand why this is happening and what can be done about it. Can you advise?

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?

Hey there. Dumb question here…I decided to order 3 samples to try out on my deck prior to buying 5 gallon drums. My deck is over a year old and I pressure washed it 5 days ago.
Question: Do I just brush on the 3 different colors of stain to see which one looks best? Captian Obvious here…but I plan on using a sprayer to handle the entire job so I wasnt sure if I should spray or brush it on.

We finished 1 coat last year of Rustic Oak on a white pine log house. Can we make it darker and more brown by using a different color for our second coat? It looks lighter and more red than what we expected. Didn’t look like the computer color chip. 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.

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.

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.

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?

Had 1500 series stain applied to 7 year old deck that previously stained about 4 years ago. Deck areas that experienced less weathering (under porch overhangs) have not absorbed the stain and have left a glaze on the wood. The glaze is still tacky, Can I and should I remove this excess with a solvent soaked rag?

I live in Maryland. I prepped the deck last Wednesday and applied the 1500 stain in Cali Red Wood. I followed the prep and application instructions and it is absolutely beautiful! I just placed the furniture back on the deck and slight movement of the furniture scratched the surface. The furniture is made of an aluminum alloy–very light. Is this typical–the finish not withstanding furniture adjustment? I’m a bit nervous because people adjust chairs frequently. Please tell me the finish will harden to resist simple furniture adjustment (especially when one scoots the chair back to stand).

Sorry about this but you do need to let TWP weather for 4-12 months and prepped first with a deck cleaner and wood brightener before staining. In addition, only apply one coat of the TWP. Mildew could be the results of pollen in the air as TWP contains and EPA registered algaecide that prevents the growing of it in the stain.

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… Read more »
