I'm looking for some advice. Yesterday one of my crews finished up an uninsulated porch. The flooring was AZEK gray decking. Throughout the project, we had covered the porch with cardboard with OSB over the top to protect it. Due to the extremely cold weather lately, we put a kerosene heater in the porch. Yesterday when my employees removed the OSB and cardboard, the decking had "lightened up" in the spot where the heater was. The area is probably 2' in diameter. It seems the decking got too hot even though the heater was on OSB.

The decking is in 16' lengths with no butt joints so I can't replace just a little of it. Each piece is about $60 so to replace them would cost about $300 + labor which I will do if there is no way to remedy this.

So....has anyone had any experience with this? I've tried a "heat gun" to bring back the original color with no success. Soap and water, paint thinner do not work either.

Are you sure the discoloration happened from heat, and not light, as in sun exposure was blocked by the heater?GMOD

Get it over with!

Unfortunatly there is no quick fix to the discoloration. Dont waste anymore time pondering it because the customer is looking at it and getting more and more upset, inturn doubting your skills and may lead to a bad referal. Do a good job and the customer will tell 10 friends, do a bad job and they will tell 100. We are not perfect but fixing the problem asap saves face.

Yeah, pretty sure it was not from sun exposure as it was always covered and the spots are in certain areas.

Its just something to consider, uv rays do some strange things, i often notice with composite decking, we can leave a piece of wood sitting on the deck surface for 1/2 a day, and when you lift it, the discoloration is noticeable. The whole surface eventually evens out, but if this is not the case for you, Suck it up< change it out, GMOD

Definitely call Azek. If nothing else, they may help with the cost of new boards as a gesture of goodwill. I think a reasonable person would assume that a heater placed on OSB would not discolour a product. I would also think that Azek has no such warnings pertaining to such. Maybe they do, I don't know. Composites scare the bejesus out of me for this reason. There are just so many unknowns with it.

That was my point too.
They sell it on how resistant
it is, they should be willing to
help out...evenif it's just to keep
your custome from bad mouthing them.
You might also tell your HO that
sun tan lotion is one of the few things
that will discolor it. :thumbsup:

A sincere thanks for your feedback. I appreciate the advice. Just got off the phone with the HO and they are completely understanding and sympathetic. I had ordered decking this morning before I posted as a "worst case" scenario. AZEK suggested that I use a heat gun to try to bring the color back.

I would have thought they wouldn't want you dickering around with it, what kind of warranty does the product have?

They say they have a limited lifetime warranty, I guess they limit what they will replace.:rolleyes:

I will keep this in mind if I ever do a job with AZEK

Are you sure you ain't just taken the moisture out from the boards with the heat. Remember these things contain moisture that darkens the color and over time they will all adjust to the climate they are in and either dry out and lighten or take in more moister and darken. They just may have to be left for a few days to adjust back to the climate they are in.

Like genecarp says decks can act strange depending on climate. I have left boards ontop of a new deck and over night it was cold and damp. When i got back in the morning the parts of deck that i had left the boards on were all a lot lighter than the deck areas that were not covered. The deck had taken in moisture over night and darkened them up. over a course of the day the direct sunlight dried them back out and they all looked the same.

So the heater dried out the OSB. The dry OSB then sucked the moisture out of the Azek decking, leaving a light spot.

Possible answer....?

Basicly yeah. Cant really word it any better than that. It sounds like it has just dried the deck out below the OSB and it needs a few days to ajust back to normal moisture content. I would leave it for a week or 2 and see if it goes back to normal color. Tell the customer that you will change it out if not.

Intersting Gentlemen. I also have seen S American react to boards laying around on it during the weekend same kinda thing same result a couple days in the sun everythings back to normal.

The idea of heat changing the color is intersting as well. It must have been that cause the area was right over the heater. Moisture hmmmmm man azek must be some strange stuff I can see the sun or lack of it making changes in color but not moisture. Picky stuff. J.

Moisture would make sense with wood.
Not so much with Azek.
