    Phil Mangan:
    I have a TREX accent deck with some areas that are discolored. Are the following products recommended by Defy to use safely on my TREX deck?
    1. Defy Wood Cleaner
    2. Defy Exterior Wood Cleaner?

    Thanks, Phil Mangan

    You can clean the Trex with the Defy Wood cleaner to remove dirt, mold etc. Not sure what you mean by discoloration as you cannot fix "fading" of the Trex.

    Susan:
    We just spent the weekend stripping old solid stain from our deck and we are now down to the natural wood. How long should we wait after the stripping is done to apply the wood brightener and after the brightener how long should we wait to apply a stain.

    You should brighten right after the stripping, while wood is wet. Stain 48 hours after brightening to let wood dry.

    The Defy Brightener will not harm the
    Azek nor will the Defy Wood Cleaner. If you are going to stain the natural wood, then you must not get any of the Defy Stain on the Azek as it will stain it.

    I have a new deck. It is Azek Deck with cedar railings and risers, with pressure treated wood supports. What products do you recommend for the railings, risers and pressure treated wood supports? Will any of them discolor the Azek Deck? Do I need to take any special precautions for this?

    The Defy Hardwood Stain penetrates new wood the best. I would suggest this.

    I am building, and sell, wood display boxes and wagons. While some are inside displays, many are used to as plant displays I people yards. I use only new wood both cedar and pine. Some of these boxes sit out in the sun and rain year round. Since it is new would, what would be the best product?

    Without knowing what the black stains are it is hard to give a correct answer. I am guessing it is water damage since it is close to the ground. If so, the balck water stain will be deep in the wood and cannot be removed with a cleaner or sanding. The wood would need to be replaced.

    I am trying to restore my redwood deck, it has black stains on the vertical surfaces close to the ground. I tried several products but can't get those black stains. I am planning to keep the natural wood grains of the deck. Do I need scrap it, sand it or do you have a cleaner that can work well.

    Roberto,

    I would use the Defy Extreme in the Redwood after prepping with the Defy Wood Cleaner and Wood Brightener.

    The cleaner can raise the pH balance of the wood which darkens it. The brightener will lower this and give the wood a more even appearance.

    I have treated my deck several times with the Defy Wood Cleaner and I was planning to apply the Oil without using the Brightener. The Wood Cleaner worked great and all of the mildew is gone, but the deck is now many different shades ranging from very light in some areas to very dark in others. The deck used to be very evenly colored and on the dark side but now it's a variety of shades. Will the Brightener help to even out the color of the deck or is it supposed to be a variety of shades? Thanks.

    For vertical newer wood we would suggest two light coats wet on wet.

    You cannot use the Defy Extreme on top of the Cabot semi-solid. It will not properly work. It needs to be able to penetrate into the wood and the old Cabot would prevent this.

    We have just stripped a "semi-solid" cabot stain from all horizantal surfaces of a very big deck in prep for a new stain. The railings and apron around the deck (that are also cedar) held the old semi-solid stain better and were not stripped completely to the bare wood. Can/Should the Extreme product (being a semi-transparent) be applied on the railings and apron, or does all wood need to be stripped down to the bare wood?

    Thanks!
    Steve and Michele

    Most likely you will not have an issue but best to always do a test spot first as all surfaces may react differently.

    Hello. I plan on using the deck stripper & brightener soon. Are there precautions that need to be taken with vinyl siding or the aluminum ballisters with the baked on metal finish? Thank you! :-)

    Jon, I would use the Defy Hardwood stain for both. It will not match exactly but it should be close in color.

    Jon · 05/08/2013
    I am installing a new cedar deck with Pressure Treated 4x4 railing posts. Is there a stain that I can use on both? Is there a stain the will make the colors of the two different woods close to matching?

    New wood should weather for a few months then be cleaned and brightened before applying the stain.

    Craig · 04/21/2013
    Is a cleaner and brightener needed for prepping a new cedar deck for stain? Or could I skip the cleaner during this initial application?
