We will reply to your comment shortly· 10/15/2020Hello,
My deck is hardwood (mahogany). Is your product a stain and sealer from weather all in one product? Which product would be best for a hardwood deck? -
We will reply to your comment shortlyMy new smooth cedar fence is installed in Southern California. After letting the fence dry out for one year, it was cleaned, fuzzies buffed-out, brightener applied, and finally, one coat of TWP stain #1530 was applied. (It looks awesome!)
If I understand correctly, your recommendation is that after waiting approximately 12 months, I should clean the fence, and then follow-up with a second coat of TWP stain?
And finally, what is the maintenance schedule following those initial two coats of stain? (ie; how often would I need to clean & re-apply the stain?)-
We will reply to your comment shortlyFences will last twice as long as a deck so do a maintenance coat as needed in 1-2 years and then redo every 3-4 years.
-
We will reply to your comment shortlyHi,
what will be the difference in process between maintenance vs. redo for the fence?-
We will reply to your comment shortlySame thing.
-

We will reply to your comment shortlyThe contractor that added the skirt to my deck put the boards on the ground. Now the boards are stained with water marks. It has one coat of TWP 1500 Cedartone that is about 2 yrs old. Any ideas on how I can the stains off before I restain with a new coat TWP? Do I need to dry the ends of the boards out with a heat gun? Completely strip and sand?
-
We will reply to your comment shortlyYou will need to strip and brighten but it will not be possible to get the water stains completely out as it is deep throughout the wood.

We will reply to your comment shortlyI have a western red cedar fence in Oregon. I have stripped and brightened it with the RAD products. It has dried for a week in 75 degree weather. I am now ready to stain with the 25 gallons of TWP 1500 that I purchased. However, it is very foggy until 10a in the mornings right now in the fall that puts a lot of moisture/dew in the air and on the surface of the fence. Do I need to wait until later in the day to stain? It would probably have to be 11 or so before it dries completely. It also starts to get dew in the air around 6p, making for a very short work day. I have a week before the rain comes and need to get this done. What do you recommend? Thank you

We will reply to your comment shortlyWhat to the dew dries off and then stain.

We will reply to your comment shortlyDo I have to wait until deck railings stop beading water before I can apply a new coat of stain. It will be same cedartone color? Hoping to avoid having to strip the old stain.
-
We will reply to your comment shortlyIs the stain on the wood TWP and when was it applied?
-
We will reply to your comment shortlyYes it is TWP Cedartone 1501. Almost 3 yrs old. Horizontal boards are mostly stain free. Railings still have stain.

We will reply to your comment shortlyOur redwood siding has been completely sanded, ready for TWP1511. Do I understand from your reply to Brian Bohenick below that since it's sanded, we should NOT plan on a 2nd coat, neither wet on wet nor a couple days later? Just one coat is best?

We will reply to your comment shortlyI have a pier 980sq ft. built in October 2018. Would like to use 1501 Cedartone. How much stain do I need?
-
We will reply to your comment shortlyMake sure to prep with this kit if never been stained prior: https://www.twpstain.com/gemini-restore-a-deck-kit-detail
About 10 gallons of stain for two coats.-
We will reply to your comment shortlyI have power washed the pier to remove the grey. Is the restore kit still needed?

We will reply to your comment shortlyWe are using 1503 to stain and preserve a PIER that is L shaped and combined 274 sq feet. Will one 5 gallon bucket allow for coverage? I am confused about 1 or 2 coats. The pier is at least 10 years old and was stained before. Now its just grey and we've replaced a few boards. Its otherwise in good shape.
-
We will reply to your comment shortlyTwo coats after prep. About 3-4 gallons.

We will reply to your comment shortlyHi. Getting ready to apply 1504 - Black Walnut next weekend. How many coats do you recommend? All remaining blue/white/gray paint has been/will removed from surface. I removed 4-5 layers of existing paint and finish sanded the entire surface with 80 grit orbital. Do you recommend wet on wet if one application do I really need to wipe excess if I don't go heavy? Or if I'm doing two coats over a 24 hour span do I need to wipe excess. Just wondering how to get access to wiping excess if any without markup up or should I just mark it up by walking on it and backbrush out?
-
We will reply to your comment shortlyJust do the one coat since you sanded the deck.
-
We will reply to your comment shortlyOk. So just one coat...wait 15-30 min...second wet coat light so no puddles...and no wipe down?
-
We will reply to your comment shortlyOnly one coat, do not apply a second coat after 15 minutes to sanded wood. No need to wipe unless some stain does not soak in after a few hours or so.
-
We will reply to your comment shortlyThank you.

We will reply to your comment shortlyIs the coverage per gallon quoted for TWP 1500 for 1 coat or 2? Does Mahogany typically require 2 coats?
-
We will reply to your comment shortlyOne coat for the coverage and only one coat for Mahogany.

We will reply to your comment shortlyI have a new redwood arbor with brick floor. The redwood is about 3 months old and has been in direct Northern California sunlight. I calculate the total square footage of the structure to be about 2200 square feet. I plan to use 1516 Rustic for staining. How much stain would you estimate to use?
-
We will reply to your comment shortlySee here about new wood tips: https://www.twpstainhelp.com/prepping-new-wood-for-twp-stains/
Just one coat after the 4+ months and the prep. You will need about 10-15 gallons of the stain and 2-3 kits of the Gemini Restore Prep.-
We will reply to your comment shortlyI'm unsure that the Gemini Restore Prep is needed. Is there any way to test the wood or otherwise verify that it is a necessary step?
-
We will reply to your comment shortlyYou always have to prep new wood to remove the mill glaze and any oxidation. No way around it.

We will reply to your comment shortlyI previously used TWP 1500 in Cedartone several years ago on my cedar fence. We didn't like the color as it was too orange. I want to go with the TWP 1500 Dark Oak this time. Do I need to strip the old TWP or just clean and brighten?
-
We will reply to your comment shortlyStrip and brighten would be best.
-
-
We will reply to your comment shortlyA friend stained our deck three years ago with TWP and it was great. We just powerwashed and are planning on staining the deck ourselves this year. Do we use one coat or two? Can we upgrade from 100 series to 1500?
-
We will reply to your comment shortlyStick with the same color and series. We would need to see a picture of your prep to determine how many coats are needed.
-
-
We will reply to your comment shortlyCalculated square footage for my deck, roughly 1031 sq ft, deck has very worn stain, will be doing strip and brighten first. Is the 1000 sqft coverage per 5 gal based on one or two coats? Was planning on getting 10 gals anyways, should that be enough?
Will also be doing a two tone look - Light stain on top of railing and floor, and dark on verticals.-
We will reply to your comment shortlyFor 2 coats you would need about 8-10 gallons but that does vary based on wood type and the age of the wood.

We will reply to your comment shortlyI will be stripping and refinishing my redwood deck in direct sunlight as there is no shade around my deck. I live in San Diego and the temp where I live reaches 88-100+ degrees In the summertime with about 15% humidity. I will be using TWP 1515 honeytone stain. So, in high temps, How can I determine if the wood is ready for the 2nd coat without waiting too long?
-
We will reply to your comment shortlyHi Frank. I also live in San Diego and stained last month. 30 mins gave the first coat enough time to soak in, but w/o drying. It dries slowly, so I probably could've waited longer. I also allowed the second coat to soak for 30 mins before wiping off excess. It is easy to recoat annually or whenever you think you need it. Wiping off all excess before it gets too tacky is critical.
-
We will reply to your comment shortlyIf doing a second coat it needs to be applied wet on wet or 20-60 minutes after the first coat. Typically decks that are older and very dried out will require the wet on wet application.
-
-
We will reply to your comment shortlyCan I get by with one coat of stain for a fence? Also how many gallons? Will be using a airless spray painter on 165 ft long, 6ft tall privacy fence on both sides
-
We will reply to your comment shortlyOne coat may not cover correctly as wood fences are very absorbent. For 2000 sq feet, you would need about 20 gallons for two coats.
-
We will reply to your comment shortlyThat comes to 100sq.ft. coverage per gallon, much lower than what's specified. Is this typical for fence due to high absorbance?
-
We will reply to your comment shortly100 Sq feet per gallon for 2 coats is correct. The spec is one coat.
