I think I ruined my new deck

Hi there,
I used timber oil to waterproof my new deck, probably my first mistake though it sounded like more natural alternative to the traditional waterproofing.
What I did was apply it with a sprayer at ten o'clock on the morning, then it got about 90 degrees out and the oil just bubbled and flaked.
To make matters worse I didn't even finish as I ran out because the sprayer was pushing it out so fast. So now I have most of a deck that looks terrible and the stairs and a small part of the deck that haven't been touched. It was Thompson's timber oil and it has a red color to it so the treated wood is a very different color. Aaahhh!
Any suggestions? I have never treated a deck before-big surprise

 

Welcome to the forums!

What prep was done prior to applying the stain? How big is the deck? how much stain did you use?

And how "new" is the deck? Had you given time for the water content of the pressure treated wood to evaporate? It usually takes several months.

 

Good point! It generally takes 6 weeks to 6 months for wood to dry out from the PT process. A lot depends on how wet the wood was when installed and the weather conditions it's exposed to.

 

The deck was built in November, I live in the sf bay area, to prep I used Thompson's deck wash with oxalic acid then pressure washed and let dry for a day

 

What is the sq footage of the deck and how much stain did you apply? How soon did it hit 90°?
I'm thinking maybe you applied the stain to heavy, pics would be helpful.

 

The deck is 144 sq ft. I used 2 gallons in a sprayer. The temperature outside went to 90 about two hours later. I believe the sprayer was the wrong method of application. While the oil was going on it seemed heavy. I should have stopped right then but I finished it out

 

1 gallon should have been more than enough stain. Did that include railings? Stain generally covers 300 - 350 sq ft although a thirsty [dry] deck will take more than a sealed or new tight grain wood. Rough texture of the wood will require more than a slick texture.

Spraying is ok for applying the stain but it sounds like you put it on way too thick. It's always best to back roll or brush over the sprayed coating to work it into the wood. I often spray on the stain, back roll and then spray another coat.

 

I agree, the sprayer was pumping it out so fast it was gone before I knew it. So now I have this crackly mess I'm not sure how to get off.

 

The original clear TWS could have the excess scrubbed off with mineral spirits but I don't know if that would work with what you used, is it still tacky? pressure washing might remove the stain otherwise I suppose you'd either have to use a stripper or sand.

I don't know what sprayer you used but every airless I've used had a control knob on the pump to turn the pressure [volume] up and down. Also what tip is used also plays a part in how fast the coating is pumped.

 

I decided to scrape off what I can with a plastic putty knife then sand, out is coming along pretty well so far. I think I will just have to go over the parts that I didn't get to after that. I will use a brush this time just to be safe.
