I never worked with hardwood before and I'm quite new to woodwork. I ordered a 2.2m long, 450mm deep and 25mm think piece of oak. I planned to sand it and treat it and use as top of a built in entertainment unit.
The piece came in early January and I put it in my shed standing longways on the floor, not flat but upright laying longways against a wall.
I didn't do anything with it for 2 months until March and when I went back to it the plank had warped very badly.
Did I store it wrong, should it have been laid flat on the ground? Or should I have just sanded and treated it straight away?
Any advice appreciated....I know it is completely my fault and a rookie error.
