Drying the scaffold boards is a fairly easy process, it just takes a little time, so getting organised is key.
The best practice is to get your boards air dried, many people feel that kiln drying is best, but we have found that this method forces the timber to dry much too quickly and many people over cook the product which just leaves a hideous board to use, almost crispy. This is a softwood timber with low strength compared to similar timbers and very long in length but not so wide, which if dried too quickly will twist!
We have found that air drying leaves us a better product to work with. Simply stack the boards on some bearers so that they are off the ground and slat with timber spacings in between each layer so that the air flow can pass through and escape easily, make sure that the spacers you are using are the same thickness and stacked evenly so that the boards are stacked flat. Also not forgetting to mention the obvious, (undercover) so that they stay dry is kind of important.
