Applying a Maintenance Coat of TWP

 

Wood maintenance is different from a complete wood restoration. Restoring a wood surface means bringing it back to a like new appearance from a neglected state or deciding to switch from one stain type to another. Wood maintenance, on the other hand, is an ongoing process to keep well-kept wood looking good. Wood maintenance is simply cleaning and recoating the wood with the same wood stain that was previously used.
In preparing an exterior wood surface for maintenance, it is important to know what type of old stain is present. TWP Wood Preservative can be cleaned and recoated easily but switching from one stain to another requires a different process. Assuming you are maintaining a wood surface that has a fading TWP Wood Stain on it, you are ready to begin maintenance.

Cleaning the wood properly is essential to get lasting results. Use the Gemini Restore Kit for this.  This does an excellent job of removing dirt, grime, and unwanted soils. They come in a powdered form that mixes with water.

TWP Tip: If the deck stain is 1-year-old, use a lesser concentration of cleaner for the prep. Try 2-3 oz per gallon of water. If the current stain is 18+ months, you may need a deeper cleaning concentration of 6-8 oz. per gallon of water.

Apply the wood cleaner using a pump sprayer or brush. Scrub or pressure wash the surface clean then rinse well. After the wood is cleaned and rinsed, it is necessary to apply a wood brightener. This will reverse the darkening effect of the caustic cleaner and restore pH levels in the wood. This will brighten the wood and help to ensure proper stain penetration. Do not skip this important second step in the wood cleaning process.

Allow the wood to dry for at least 48 hours prior to staining. Protect things you do not want the stain on, like windows, shrubbery, concrete, or siding using plastic or tarps. Always wear protective gear like gloves, mask, and safety glasses.

Apply any of the TWP Wood and Deck Preservatives using a brush, stain pad, roller, or garden pump sprayer. It is best to start up top on high surfaces like wood siding or gazebos and to work your way down. On decks, stain the railings first before staining the deck floor.

Be sure the TWP stain is fully penetrating the wood and wipe away any excess stain that remains on the surface. Remember, there is still an older coat of stain in the wood so you will not apply as much stain on a maintenance coat as you would on bare wood surfaces. Stain each board or piece of wood from end to end. Stopping in the middle of a section can create unsightly lap marks. Once you are satisfied that the wood has absorbed all the TWP stain that it can you are finished.

I had my deck stained yesterday with twp ws cedartone. They did a terrible job and only applied one coat. There are many lap marks and no stain between the boards in many places. Can I have a second coat applied to fix these problems?

Live in Atlanta, GA and need to apply a maintenance coat (after cleaning and pressure washing) to a deck that has previously been coated with TWP 100 Cedartone. Would you recommend using TWP 100 again or TWP 1500? Also for this maintenance coat do I need to apply two coats or just one? Thanks in advance for your response.

I have cedar siding the its pretty worn in some areas. The previous homeowner used cabot oil stain and it was done a very long time ago I’d say at least 5yrs. I’m trying to avoid power washing because it isnt dirty and I dont want to damage the cedar. Could I apply TWP1500 on the siding as is? I know anything isnt a guarantee, so I promise not to hold you to your word. Just need guidance.

We stained our mahogany deck with 1500 Clear last Fall – now that the snow has cleared from the deck (it is a covered porch) – there are a few boards that need some stain re applied- We just purchased the Gemini kit – but our question is can we just treat the 2 boards that need more stain? We really do not want – nor need the rest of the deck to be done again. thanks

I am preparing to stain my deck with 100 pecan. Used steps 1 and 2 last weekend and wanted to apply stain in the upcoming weekend. My question is about pollen. We are seeing large amounts of pollen settling on all exterior surfaces in the south–will probably last another week or so. Will pollen settling after application affect the appearance/durability of the product? My problem is my helper is only available friday-monday–yikes!Thanks in advance!

We built our deck two years and 4 months ago, prepped and applied a stain about 18 months ago, it is time to do a maintenance coat correct? For applying a maintenance coat, this article says “Apply the wood cleaner using a pump sprayer or brush. Scrub or pressure wash the surface clean then rinse well.” When we used a pressure washer for the 1st application of our stain (18 months ago) the pressure washer must have been too strong, it left our deck looking fuzzy. Most of that fuzziness is gone now, but I’m afraid to repeat the same… Read more »

I applied TWP 1500 1511 to a cedar deck in May 2017 that was 7 months old. The deck was prepped according to instructions using your cleaner and brightener kit. The stain on the vertical surfaces is fine and looks great. Unfortunately, the stain on the horizontal surfaces is actually coming off and/or appears very thin in some spots. I have plenty of stain leftover. Can I just reapply to the worn areas or do I need to apply to the entire horizontal surface? What went wrong?

I will be applying a mx coat to my redwood deck using TWP 100 Cedartone. I last applied this stain as a new application (after complete sanding, washing, brightening) in Sep 2014. This included all railings and other vertical surfaces.

The vertical surfaces still look good and the only places that “seem” to need a new coat are the horizontal tops to the railings.

Question: My plan was to skip the vertical surfaces, is this a bad idea?

I have 2 kinds of redwood siding: one is horizontal lapped, over 100 years old. the other is rough sawn board and batten, about 70 years old. About 10 years ago I applied Preserv-a-wood clear penetrating oil finish. The wood is still pretty good looking , but has some graying at the low end of the boards on the west side. Will I need to strip the wood? If so, is it because the oil in Preserv-a-wood is not compatible with the oil in TWP? Thankyou.

I have a redwood deck that I stained with 1500 in 2014, at this time, there is very little indication that it has ever been stained, see picture. I am willing to try it again with the remaining stain (over 1/2 of a 5 gallon can) that I have kept stored in a sealed plastic paint container. Will it still be useable to stain it again? I assume I will prep as described in the maintenance section.

We had a new pressure treated wood deck installed during the Summer of 2015 and waited until the Spring of 2016 to stain the deck with one coat of TWP 1560. I was told not to apply a 2nd coat until this Spring and I’m preparing to do so. The deck looks great. Should I use both the cleaner AND brightener in the Gemeni Restore kit or just the cleaner? Also, do you recommend applying a 2nd coat of stain to the rail balusters or is one coat sufficient?

I just finished the first coat of TWP 100 on my deck, but I ran out of stain before I could do a second “wet-on-wet” coat. Now I have to reorder and it will be at least a week before I can do a second coat. Are there any special steps before applying a second coat?

The deck is cedar, 1 year old, cleaned and brightened before staining. This is the first coat of stain on this wood.

Thanks,

My deck was stained almost 2 years ago with TWP I want to restain it but some parts of my deck are in complete shade and still repel water while other parts the stain is worn off and absorbs water. Will I have to strip the deck or will using the cleaner and brightener allow the stain that is in good shape allow stain to penetrate those areas?

I have a customer who has hated the Dark Walnut stain since day two. I finished the job last year. She now wants me to stain it a lighter color or replace the entire deck (her dime). Is there a way to lighten the stain? If not, can I use a light colored solid stain over the TWP after a Gemini clean? BTW, I think the deck looks great. It is hot though. Love your products.

You cannot lighten it by adding more stain. You can remove it and start over. Use the Restore A Deck Stripper and Brightener Kit. Once removed, she can use any color she wants.

We stained our deck Summer 2014 with TWP 100, 1 part dark oak, 2 1/2 parts pecan and got a very nice brown finish rather than the red tones. We plan to clean and maintain this summer. Once we do the Gemini plan, can we just use the natural stain to maintain the current color, but get the water/weather protection? Do we really need the brightener in this case, as we assume the natural is basically a clear stain
?

No you cannot use the Natural over this. You should use the same mix, just one light coat. You do not need the brightener.

Confused on this and similar replies. Thought that when you use the Gemini cleaner, you need to use the brightener to “neutralize” the PH level …. No ?
So your saying that if its a maintenance clean ( to reapply the same TWP stain after a few years or so ) you only need to use the cleaner and not the brightener ?

I had a pressure treated deck installed a year ago. The contracted used TWP 205 California Cedar. They insisted that the 200 series was best for decks even though the spec sheets show differently. The deck developed a lot of severe cupping which I had to drum sand out. I am planning on using the same stain on the deck for this treatment as I don’t see the 205 california cedar in any of the other twp deck stains, is there anything I should know about the 200 series application, and next time should I switch to another TWP?
