TWPStainHelp.com Tips: TWP Stain Application is Spotty/Shiny and How to Fix
Staining a deck can be a challenge. There are some common mistakes that can occur that may greatly affect the final results. One such common mistake is over applying the stain.
With TWP Stain it is recommended to apply the stain using a brush, roller, or some type of sprayer. If the wood seems very thirsty, you can apply two “wet on wet” coats. TWP is a penetrating stain so you should never apply more stain than the wood can absorb. Once the stain as had 20-40 minutes or so to penetrate into the wood, you should go back and wipe away or back brush any puddles, drips, or runs.
When excess stain (stain that did not soak in) is left on the surface to dry it becomes shiny. This can give the deck an unsightly spotty or blotchy appearance. If you notice your TWP Stain application is spotty/shiny you should know how to fix it.
Once the surface has dried you can see the extent of the spotty or shiny issue from over-applying. To fix it you can lightly wipe your deck with rags and mineral spirits to remove the excess stain that is on top of the wood.
Note: it is very important to saturate all oily rags with water once done. Lay the rags flat on the ground outside to dry fully.
If you are still having trouble removing the shiny spots, meaning the stain is too thick, you may have to use a stain stripper. You can also try sanding the areas using medium-grit sandpaper. Once the problem areas are cleaned or sanded off, allow the deck to dry before reapplying a light coat of TWP.
Only apply TWP to the areas you cleaned or sanded. Apply as much stain as the wood will absorb but no more. If the stain is not soaking in after 10 minutes wipe the excess away with a clean rag or brush. Try to even out the finish as best as possible without over-applying.

I’ve been using TWP 207 Butternut Brown, but see it now only comes in 5 gallon pails? I only need a gallon, so which color in TWP 100 or 1500 matches closest on pressure treated wood? Thank you.
It comes in gallons: https://www.twpstain.com/twp-200-series-5-gallon
It’s been about 12 hours since my contractor applied TWP 100 in cedar tone. Seeing lots of sheen this morning. Do I need to let this cure more or should I intervene?
You can wipe it down now.

We have a new wood deck that we just stained with TWP 100. We wiped away excess after 30 minutes but most of it had soaked in already. The wood looks very blotchy. What happened? The wood was dry when we applied and no rain.
Did you follow the directions for new wood?

I didn’t use the kit you describe but did clean with soap and water and rinsed well. I let it dry for over 2 days. Is there anything I can do now or will it look better when the second coat is applied in a year or so.
Best to just prep and eapply next Spring. It will not take another coat now.
We used TWP stain over the summer to stain our new deck. As you can see, some spots still have a ‘wet’ look to them. It’s been a few months so I’m not sure what our best option is. We live in Southeast Texas so that means lots of humidity. We also have black (moldy??) spots that have showed up over the last week. Did we not use enough stain? Thanks in advance!
You over applied it and possibly did not prep correctly. Not sure if you followed the new wood instructions? https://www.twpstainhelp.com/prepping-new-wood-for-twp-stains/
Best to redo this Spring. Strip and brighten for prep.
I did a test sample on my house with 1500-series pecan and it looked pretty good with a nice warm brown tone. Afterward, my contractors sanded down all of our cedar using 40-grit sandpaper and then applied a sampling of the pecan and it came out very blotchy and red. The outcome was night and day compared to what I originally tested. The first photo is the first test sample I did after cleaning and sanding with 80-grit. The second photo is the test area the contractor did after cleaning and sanding with 40 grit. The third image shows the siding in the process of being sanded. Do you think the 40-grit sanding could have something to do with this? If so, is there a grit that you recommend for clear cedar?
The final color is due to the wood itself, how old it is, and how it is prepped. There is not a way to sand it a certain grit and have it come out a given color.
Our deck is 12 years old. We hired a company to prep and stain it. They power washed it with a cleaner but there was still black moldy areas. We’re replaced some of the boards and all the top hand rails. We bought RAD stripper/brightner and power washed a second time. After it dried they lightly sanded the splinters and applied TWP 1500 in Dark Oak. There is variations in color on the old wood and the new wood has splotches. The old wood was very thirsty and the guys applied many coats. They might have over applied the stain as I suspect. Is there anything we can do to make it better or shall we wait? We appreciate any advice.
Pics. after staining, and few days later after it rained.
Nothing you can do at this point. Clean and apply another coat next year.
Thank you for your response. How do I clean next year?

Hello,
We rec’d our 5 gallon 1500 stain and will be renting a sander to take off the peeling stain on our redwood deck. it’s 3 year old, we live in Denver, CO. My question is: if we sand today (Friday) 88 degrees and sunny and we stain tomorrow (Saturday) same weather; will the deck be okay if we are getting snow (Monday night into Tuesday?) It will be 50-60 on Wed. and Thursday and sunny. We are just getting that one crazy snow day. How long should the stain dry before it gets snow?
Thank you,
Tammy

Hello,
After sanding, I applied TWP 1500 in cedar tone to a portion of my deck. It’s been about 5 days since application, and there are still some shiny parts which have not been absorbed (see photos). The shiny parts are smooth and not tacky.
Do you suggest any remedies for these shiny areas or is it better to just allow time for the deck to weather at this point?
Thanks for your help!
You can lightly wipe your deck with rags and mineral spirits to remove the excess stain that is on top of the wood.
Note: it is very important to saturate all oily rags with water once done. Lay the rags flat on the ground to dry fully.
cloudy finish has appeared on log cabin is it time to do a maintenance coat

I just finished having my deck stained. I did not do it myself but paid a professional. I gave him all the instructions for proper application. He finished on Wednesday afternoon and I didn’t go out to walk on it until today and was disappointed with some of the splotchy boards. It’s not on every board but is on quite a few. Is this from over application? He used a roller to apply. I told him he needed to remove any excess with a brush or rag but he assured me it would soak in. Can this be fixed now with a rag and mineral spirits? I found a section on spotty/shiny boards but wanted to be sure that was the issue here. Please see pictures. Any advice is greatly appreciated. The boards without the splotches are lovely. He only applied one coat. I have a lot left over so I thought I might re-do it next year to get a second coat on. Thank you.
Try to wipe the spots down with mineral spirits and rags to see if that helps.
The attached is the result of a company that cleaned and stained my deck. The deck is three years old. I advised the company of my concern and was advised the result is due to not getting all the old stain off with cleaning and the deck would now need to be sanded. I’ve had many deck cleaning and staining done in the past and have never seen this result. I was never advised either of the risk of cleaning not getting the old stain off. There was a strong rain storm within 2 hours after staining. I asked about that and they were not too concerned, but if need be they would re stain. To me, only re staining at this point, will only make it look worse. Feedback appreciated as to my options and if I should request my money back from this company.
The rain did not harm it but there is some deeper discoloration in the wood. Does not look like an old stain but internal wood discoloration. Not sure if that would be their fault though.
Thank you for your feedback. Would sanding then and re staining turn out better do you think?
Not sure if it will come out, it seems deep in the wood grain.
We hired a company to clean and stain our deck. We’ve had this done before and always use TWP stains, but this result we have never seen before. I’m being told now after complaining to the company, that this is the result of the old stain not coming off with the cleaning and the deck will now need to be sanded. I was never advised risks of not getting all of the old stain off with cleaning. I was told there could be some “blotchy” look but that it would go away. There was a rain storm, heavy rain, within a coujple of hours after staining. I called and they were not too concerned about it and if a concern they would re stain it. But I’m concerned now, only re staining will only make it worse. The attached picture is about one week after staining. Attached is picture of result. Feedback is appreciated.
deck furred and twp taking unevenly. it grabs the stain darker over the furred areas. I tried lightly sanding whit 80 grit and it did not seem to help. should i have the deck sanded. the prep was stripped and brightened with Behr. I may have been too aggressive with the stripping product and the grain suffered
Yes, you would have to remove, sand, brighten, and then restain.
The brightener seemed to raise the grain. You would still have to use it after sanding? Is the Behr cleaner and brightener not a good choice? I would assume that they all do the same
You want to open up the pores so the stain can soak in after sanding. Do not use the Behr.
What product would you recommend to clean/brighten?

How long after staining can you put rugs and tables back on deck? I finished last Sunday with the TWP Pro 100 Series.
You can do it now.
Hello, unfortunately my deck looks shiny after 48 hours of drying . The railing looks great because I used a paint brush. The floor looks shiny even l remove excess and the next day l used a mineral spirit to remove the shiness. I am so confused why the boards did not absorbed the stain and dried shiny. Can l leave like this or the planks will be damaged and prone to mold?
You over applied and or did not prep correctly. It will be fine though so just let it fully cure.
After it fully cures will the shiny spots go away I have the same issue with my tongue & groove ceiling ?
Yes, they should go away.
I applied TWP101 cedartone yesterday. I used wet on wet, spraying it on and brushing it in. I didn’t notice any pooling and it didn’t seem excessive. This morning I rubbed some of the boards and came away with kind of an oily residue. When I wiped it a little with a paper towel there was stain on the towel. It will be a good day of drying today, 90 degrees and windy. Should I try to wipe down the boards which seem a little “oily”. They don’t really seem shiny.
No, just let it dry out today, it should be fine.
We just paid a man $3000 to apply stain to our deck. We had new cedar flooring, rails and stair treads put on last fall. We let it age 7 mos. He came back last week to power wash it and prep it for staining. He said that it was the fault of the wood that it is spotty saying the knots soak it up faster. When we inquired about options for fixing it he said we just had to wait a year and a half for it to wear off. If he applied anymore it would just bubble up and flake off. Then the stairs are very dark and spotty and shiny. It appears very uneven to us. We’re wondering what other options there might be?
He is correct. Knots are a denser and will take the stain lighter there and adding more will not darken them and could lead to over-application issues. The stairs need time to cure and will even out.
So we will have a polka dotted deck til it wears off?? There are no options for fixing this? I’ve never seen this before on any decks I’ve been on. Is it common? Isn’t cedar a common deck material? I am feeling very frustrated.
It also rained really hard the night after he applied the stain. Could this have affected the stain?
Could this result have happened because it rained really hard the night after the stain was applied? If the knots take more stain than surrounding wood, why are they lighter and not darker? I’m having trouble finding any other examples of decks that look like ours.
No, and it is not the stains fault but your wood. It has a lot of knots, more so than normal.
I’m not trying to blame the stain. I’m trying to get help to figure out how to fix it and make it look nicer. Is it possible to power wash and restrain. Do I need to let the Wood age longer. I’d be fine if the knots looked darker not lighter. That is my question.
I am not sure adding another coating will work or not. You can try but it really comes down to the fact that this is the way your wood/knots are accepting the stain. I am thing the grade of the wood is not of the best quality?
Do a test board and see how it looks and dries after a day or two. If better and it dries fine, then lightly recoat all floors.
Applied TWP two days ago. Stain is dry to touch, no spotty/sticky/glossy areas, but when walking on the deck and coming indoors their is a slight oily brown residue on our feet. Does this eventually go away or is there an issue?
It will cure fully, give it some more time.
So I used the restore a deck and brighter. I used one coat TWP dark oak using a brush. This is the result. If I let this go will it be ok. It’s a little tacky. I don’t want to strip this deck again.
It will be fine.
Hi! So I over applied…. Tried wiping w mineral spirits but it kept raining and more kept coming out… Huge mess. I’ve stripped the deck twice and it looks good except several places w larger cracks have oily spots still. Do I need to keep stripping it until it’s gone or move on to the cleaner/brightener?
Also, the wood (cedar) seems so thirsty. It was neglected before I moved in. I applied w a brush. Would a roller put on less stain maybe? I don’t want to screw it up AGAIN
Post a picture of the prep so far. Apply with a stain pad, not a roller.
Ok – pad it is.
Here’s a picture of an oily board. Don’t have a dry picture and probably won’t for a few days but when dry, it isn’t shiny and tacky anymore just darker in the more open grain spots
We would need to see a dry picture.
Ok I’ll get back to you. Thanks for the quick responses!
Okay, here’s the deck dry. The dark spots are where it’s still getting a little oily when wet and actually I can rub off a little excess still in some spots.
Sorry if this is posting several times, I’m having technical difficulties!

Looks fine for prep. Use a stain pad for applying, only one coat.
Great, thank you!
I applied test patches for a few of the TWP 1500 colors I’m considering to my deck that was sanded, stripped with RAD and pressure-washed off, sanded again (60 or 80 grit), and RAD brightened. The stain didn’t seem to be absorbing well, and the colors look essentially the same. There is more color variation of the same stain on different boards than there is between different colors on the same board. The railing pic from L to R has pecan, cedartone, and natural. The floor pic top board has natural, clear, and pecan. Bottom board has natural, clear, cedartone.
I’m worried that it will end up blotchy since it’s not absorbing well and there is distinct color variation of same stain on different boards. Stripping the old Sherwin Williams oil based Deckscape has been extremely laborious, so I want to get this right the first time and not have to redo. Thanks!
